-------Update History------ [L4DUPDATE]
**************************************************************

1.0) FAQ's initial posting.

1.1) 7/8/09 - Minor spelling / grammar corrections throughout the
guide. Some additional strategies and corrections to the Dead Air and
Blood Harvest campaigns.

1.2) 7/12/09 - More minor spelling / grammar corrections. Several
alterations to strategies in the Death Toll, Dead Air, and Blood
Harvest campaigns. Added several new tips in the No Mercy campaign.

1.21) Minor update. Granted permission to several other website
editors/administrators to post this FAQ. Said websites can be seen in
the "Legal Stuff" section of the guide. Thank you for the recognition!

1.31) 12/14/09 - Major, major, major update! Added Crash Course
achievements and added a rough "skeleton" style guide for the Crash
Course campaign. It should be updated with more strategies in the next
few weeks.

The reason for my delay in the update of the FAQ? It's a long story,
and now you have to read it...if you want.

My computer was crashing with CPU over-temperature errors. I'm
thinking: "Ok, sounds like my CPU fan is failing or the thermal
compound on my heatsink is coming loose. $30 quick fix."

Not to be...

Turns out my CPU was failing. $160. I figure if I have to replace
something, I might as well upgrade! Well, the shop I went to for
installation didn't install the CPU correctly. This sent my Power
Supply into "overdrive mode" and it surged...badly. Ended up destroying
my Power Supply, my Motherboard, my CPU (again), and my graphics
card...

$600 later, I got my computer back up and running and I got to working
on the guide again! So don't think I'm lazy! Computer parts aren't
cheap, especially when you have a pretty high-end gaming rig like
myself.

And that, my friends, is the reason for the delay in my 1.31 update to
this FAQ.

1.32) Minor update. A few spelling errors corrected and granted
permission for this FAQ to be posted on another website. Said website
can be found in the "Legal Stuff" section of the guide. Thanks for the
recognition!

-------About the FAQ------- [L4DFAQ]
**************************************************************

So you've gone ahead and entered what many consider to be the most fun
part of Left 4 Dead.
You've entered Versus mode. And you're here because...

Well, let's think through this logically first.

1) You enjoy reading everything that can be read. You're bordering on a
mild case of Obsessive Compulsive Disorder.

2) You'd like to learn some strategies to help you out with your Versus
mode career in Left 4 Dead.

3) You clicked on the wrong link, but because you had a feeling about
how awesome the author is, you decided to stick around.

But seriously now...we both know why you're here, really.

4) You got your ass handed to you gift-wrapped with a "Get Well Soon"
card attached to it.
You've probably been kicked out of a game or two by angry teammates who
thought your I.Q. didn't exceed water's freezing point...in Celsius
degrees. (For the record, that's 0)
You've been accused of having a "Fail Tank" on numerous occasions.
You find yourself rage quitting more often than not.
You actually find playing as the survivors more fun than playing as the
infected.

If #4 was correct in any of those areas, fear not, for there is help.
Welcome to "The Infected Handbook." Your one stop source of all
information on the zombie side of Left 4 Dead. This guide will cover a
wide berth of topics ranging from individual map strategies to tips and
tricks for using and exploiting all five of the special infected
characters. This guide will help you succeed in stopping the survivors
in their tracks. But most importantly, it will help you regain that
lost confidence. Help you to become a great team player. And help you
discover the potential you have within yourself.

This guide was written with YOU in mind, my friend.

-------About the Author------- [L4DAUTHOR]
**************************************************************

I'm Eric. I've been a member of GameFAQs since April 30th, 2002.
So yeah, I've been around. I picked up Left 4 Dead a few weeks after it
was first released, so
I've been through plenty of updates. And I know what I'm talking about.

I am awesome. You are not.
I never wear a cape when I fly.
I have at least $30 in my pocket. That's probably more than you have
right now.
I can lead a horse to water, AND make it drink.
I keep telling your mother that she can't have me. She doesn't get it.
Sometimes I sleep in your back yard.
I give off a constant 1.21 Gigawatts, so if you have a Flux Capacitor
and a Delorean, we could time travel.
I am no longer in the Mafia.
I have played Left 4 Dead more than you have.
I invented rubber bands.
Your friends will like you 30% more if they find out you know me.

But all facts aside, this is my first FAQ. And since Left 4 Dead is
still a pretty new game (by this FAQ's initial post), there's bound to
be things that I will miss. That being said, if you find anything
inaccurate or have additional strategies that aren't too well known,
please let me know. I'll post them in the FAQ and give credit where
credit is due. My e-mail address is listed at the beginning of this
FAQ. That's probably the best way to contact me. Otherwise you could
try calling random telephone numbers, but I don't really recommend
that.

I'm writing this FAQ up to date. If things get patched, I'll change
them as soon as I can. There will be nothing in this FAQ talking about
how it "used to be." I will diligently alter this FAQ to keep it up to
date in accordance to any change that takes place with future patches
or download content that makes alterations to VS mode in Left 4 Dead.
That's just the way I am.

This FAQ also doubles as a "What to expect" guide. Because it points
out ambush locations, some of which are less common, it provides sort
of a reverse "How To" perspective on the survivor side of Left 4 Dead.

Now let's get started, shall we?

**************************************************************
-------The Hunter------- [L4DHUNT]
**************************************************************

"Cause we hunt you down without mercy! Hunt you down all nightmare
long!" - Metallica

Hunter Specific Achievements:
***Double Jump*** - Pounce on two survivors in one life as a Hunter.
This is a fairly straightforward achievement and can be accomplished in
one of two ways. The easiest way is by pouncing on someone, and being
shoved off your victim, but not killed - allowing you to run away and
pounce again. The other way (and more fun way at that) is by pouncing
on someone and outright killing them...THEN pouncing on someone else.
To my knowledge there is no way to get yourself off of someone you have
pounced before they die.

***Jumpin' Jack Smash*** - Pounce a Survivor for 25 points of damage in
the Crash Course campaign.
While you may have experience in landing big pounces in the other four
campaigns, Crash Course offers a surprisingly low number of areas in
which to land one of these monster pounces. The easiest area I've seen
to get this achievement is in the 2nd chapter of the campaign while the
survivors are starting or re-starting the generator during the finale
event. You can perch at the top of the tall depot building and take
advantage of the stationary target survivor as he/she attempts to start
the generator.

Primary Attack: Pounce
Secondary Attack: Claw Swipe
Health: 250

When it comes to dishing out damage, the Hunter is the breadwinner in
the infected family.
A four player infected team will always have at least two Hunters, but
on some occasions, a
four player infected team can get three, or on even rarer occassions,
four Hunters.

Hunters are fast, agile, strong, and hard to pick out of a large crowd
because of their appearance.
The Hunter's main attack is pouncing on survivors. A survivor who has
been pounced on by a Hunter cannot defend themselves while being ripped
to shreds and needs a teammate to rescue them.

Pouncing is done by crouching (default Ctrl key) and left-clicking. To
get more distance out of your pounce, make sure to aim slightly upwards
for a nice arc. With some practice, you can start landing big pounces
with some consistency to really mess up a survivor team. You will get
the most distance out of a pounce if you angle yourself upward about 45
degrees. From the various perches you can reach in the game, it takes a
bit of practice to know when to time your pounce, what angle your
pounce should be at, and how much directional play mid-air you may need
to put into your trajectory in order to succeed in landing on a
survivor. Unfortunately, there's no real way to try and teach this
through a guide. All I can say is practice, practice, practice! You'll
get it. It may be best to start off trying for shorter pounces to get a
feeling of how the physics engine affects your trajectory and moving up
from there. If you can comfortably and consistently land 10-13 damage
pounces, try stepping it up a bit. Go for those 15-18 damage leaps. And
once you get consistent with those, go for the monster 20+ damage
pounces.

The damage a pounce does on contact varies from 1 to 25. Yes...25. The
BIGGEST factor in determining pounce damage is DISTANCE, not height,
and not both. The further your pounce, the more damage you will do on
contact. If you pounce straight up from a rooftop and land that pounce
on a survivor directly below you, you will only get probably a 3 to 4
damage pounce, however, if you are on a very high perch and pounce
straight down to land on a survivor, you may get a large amount of
damage on contact. The way it works is kind of screwy and I've yet to
figure out how exactly damage is calculated with a pounce straight
down, as pounces that have a lot of height may only yield a modest
amount of damage the first time, but manage 15+ damage from the same
spot the second time. This kind of wishy-washy occurrence may possibly
get changed in a future patch, but as of now, go for long pounces
instead of high ones for the best results.

The Hunter's pounce will interrupt a Smoker's tongue attack while he
has a survivor constricted. It is 90% of the time BAD to pounce on a
survivor constricted in the Smoker's attack. For a couple of reasons:

1) Now the Smoker has to wait 15 seconds for his tongue attack to
recharge, essentially making him useless or a sitting duck for the
allotted time.

2) Only 1 survivor ends up being rendered helpless instead of a 2nd
survivor coming to the rescue you could have pounced.

The only time it's actually beneficial to pounce on a survivor in the
middle of a Smoker's attack is if you can get a big damage pounce
(we're talking about nothing shy of 15 damage here) when 2 or more
survivors come back to help their trapped friend and the Smoker has an
easy escape route. You need to make sure you can dish out more damage
than that Smoker could have ON CONTACT because now all of the survivors
are together, and one of your allies was about to die. Pouncing on the
constricted survivor in this (and only this) scenario is beneficial to
the Smoker on your team as it can allow him to run away and find cover
while his tongue attack recharges and you still dished out more damage
than just the tongue attack would have done.

Because Hunters rely on the element of surprise, you'll almost always
want to spawn in front of the survivor team. There are some occasions
where it's helpful to spawn behind them, but get into the habit of
setting up for big pounces for when the survivors enter your particular
area. There are many areas in most of the chapters of each campaign
which can yield big (20+) damage pounces. I will explain and point out
those areas in detail later in this FAQ.

The Hunter's secondary attack is his normal melee claw swipe. This
attack does 6 damage per hit. It doesn't seem like much, as it will
take 17 claw swipes to incapacitate a survivor from full health, but
realize that if you can dish out over 25 damage as a Hunter in one
life, you're doing fine. The Hunter makes no noise when not crouching
and only screams when he has a survivor within his sights, so you can
silently sneak up on people and get a couple of melee swipes off. If
you miss a pounce in the middle of the survivor team, usually it's
better to try and get at least one claw swipe off because it will
result in more damage than a close range pounce. And you'll more than
likely be quickly killed by the survivors. A claw swipe can hit
multiple targets - a pounce cannot. There are also a number of areas
where survivors commonly huddle up into a corner to hold off a
crescendo or finale event. Claw swipes may be more beneficial because
of their ability to hit multiple targets.

Hunters love stragglers. Hunters also love rushers. If a survivor is
alone, target him/her. A successful pounce can result in excess damage
as the rest of the survivor team needs to backtrack or catch up to
rescue the downed survivor. You may also want to take advantage of
making pounces on a survivor in the process of helping up an
incapacitated teammate. Regardless of who you pounce, it's beneficial.
If you pounce the survivor helping up the teammate, you obviously
render two of them helpless, though the downed survivor could easily
shoot you off the one you pounced. If you pounce on the incapacitated
survivor, you'll reset the revival time by making the rescuing survivor
stagger back and hasten the "bleed out" timer for the incapped
survivor. Depending on the situation, you can really break the
survivors down. Remember that you can always press Tab (by default) to
monitor the health of the survivors. Also, if you think a pounce isn't
worth it, using your claw swipe on the downed survivor as he/she is
being helped up will reset the revival timer.

That being said, it's usually in your best interest to focus your
attacks on the survivor with the lowest health. Killing the first
survivor is always the hardest part, but once you do, the other three
go down rather quickly if your team can co-ordinate an ambush. A four
player infected team will always have at least 3 people who can render
a survivor helpless, so all it takes is a little planning.

Ladders are great choke points for Hunters. Not only do they force the
survivors to travel in one direction for a short time, but in some
cases, a pounce on a climbing survivor can result in tremendous fall
damage as you'll send them (and anyone else on the ladder) all the way
to the bottom! I will go into greater detail pointing out these
locations later in this FAQ.

The Boomer is the Hunter's best friend. Because the Boomer's vomit
blinds survivors, Hunters love to jump in on the action. A survivor
blinded by a Boomer's vomit cannot see the outline of the pinned
survivor as he/she is getting ripped to shreds. Simple logic will tell
you to go after any survivor who was NOT VOMITED ON by the Boomer. By
pouncing on the unaffected survivor, you can potentially dish out
tremendous damage as the vomit-dripping zombie magnet survivor(s) will
need to not only fight their way through a mob of infected, but also
have to locate their teammate. A survivor vomited on by the Boomer will
be able to see clearly again about 10 seconds after the vomit first
made contact, but the outlines on any pinned survivor will not be
visible for a few more seconds, so take that into consideration when it
comes to picking your target. It's not uncommon for one of the
survivors to run off while their teammates are still technically
vomited on, and not see the silhouette of their teammate being torn to
shreds until after a decent chunk of damage was inflicted.

Hunters can reach places no other infected can. This means very high
perches that may not even cross the minds of the survivor team to check
before venturing onward. Remember, the element of surprise is a great
ally for the Hunter, and if you can find a good ambush location that
not only conceals you, but also allows for a massive damage pounce, all
the better. Hunters can also wall jump to reach places a single pounce
cannot. Aim at a wall, pounce, then while you're in mid air, aim where
you want to go, and as soon as you hit the wall, pounce again. With
some practice you can reach perches many people never bother to check.
And now you can make them pay for it! There will be various locations
listed in each chapter of each campaign for you to take advantage of
later in this guide. Hunters can also use wall jumps to travel much
faster through areas with narrow hallways. The hospital level in the No
Mercy campaign is a great place to practice this. Many times you can
actually close the distance between you and a survivor taking aim at
you by simply jumping from wall to wall and finally landing on one
them. It takes a lot of practice, but it's one way to really surprise
someone.

Wall pounces can also be used vertically to reach extremely high
perches. Against a flat surface, face away from the wall, aim straight
up and pounce while holding back (default "s" key). While in midair and
holding back, angle yourself forward about 10 degrees or so and pounce
again. With practice you can string together 5+ of these wall pounces
to reach some incredible vantage points - some of which that get
completely overlooked by many survivor teams.

If you see a survivor pinned by another Hunter and the other survivors
aren't in a position to rescue him/her quickly, join in by using claw
swipes on the pinned victim. This can cause incapacitation much faster.
Just make sure you're aware of your surroundings and can pounce on
someone coming to rescue when you get the chance!

A Hunter on fire is now a bad thing. In the campaign and survival
modes, a flaming Hunter is a force to be reckoned with as they dish out
BIG damage in a short time. VS mode...not so much. The damage you do as
a Hunter while on fire *is* greater, but it was severely toned down in
a patch. Because the damage was reduced by such a large degree, it is
generally considered a bad strategy to light yourself on fire before
pouncing on a survivor. You can weigh the pros and cons against each
other.

Pros:
+ Double damage while pinning a survivor.

Cons:
- Most survivor players avoid fire and only use molotovs or gas cans
when they really need to.
- You are losing health, so you are easier to kill.
- You are easier to pick out of a large crowd.
- You may have to go out of your way to light yourself on fire, then
try and catch up to the team.
- You probably won't be able to get a big damage pounce while on fire.
- You need to immediately attack if you wish to deal ANY damage at all.
- This makes you less of a team player because now your teammates must
compensate.
- Less active infected players hinder the possibility of a devastating
ambush.
- You cannot wall pounce while on fire.
- You run slower.

Yeah...do yourself and your team a favor by NOT lighting yourself on
fire as a Hunter. If you get lit up by a molotov, then yeah, go ahead
and try to dish out a little damage before you burn up. Just don't
voluntarily light yourself up. Remember, there is no way to stop, drop,
and roll in this game.

Happy Hunting!


**************************************************************
-------The Smoker------- [L4DSMOKE]
**************************************************************

"Got you in a stranglehold baby, you better cross your way!" - Ted
Nugent

Smoker Specific Achievements:
***Big Drag*** - Drag a survivor 100 feet with your tongue as a Smoker.
I actually found this achievement rather difficult to unlock. It's
easiest against stragglers. Spawn behind them, and use your tongue
attack as they're running away from you, trying to catch up to their
team. As long as the targeting reticle is red when you used your tongue
attack, it WILL connect unless the survivor goes around a corner. Drag
them all the way back to you to get this achievement.

***Chain Smoker*** - Constrict 2 survivors on one life as a Smoker.
Fairly easy to unlock. I found the best way to get this is by sticking
to rooftops and aiming straight downwards to snare a survivor. Most
times, a rescuing survivor will simply melee attack their teammate and
break your hold. Wait 15 seconds, and do it again.

***Slippery Pull*** - Smoker pull a bile-covered Survivor until you
hold him during Crash Course.
Simple enough. The easiest way to get this achievement is to have the
Boomer on your team cover all four survivors at once with puke, then
try to get as close as you can to the survivors before you try pulling
one. If you're at point-blank range when you use your tongue attack,
you will instantly ensnare the survivor and get the achievement.

Primary Attack: Tongue Snare
Secondary Attack: Claw Swipe
Health: 250

United we stand, divided we fall.
The Smoker serves one major purpose in Left 4 Dead. Separate the
survivors.

Smokers aren't nearly as fast, strong, agile, and quiet as Hunters are.
And many would say that the Smoker is largely a situational character.
I whole heartedly disagree. A good Smoker player knows when and how to
pull a team apart when they're vulnerable making it easier for
teammates to orchestrate their attacks. Smokers, along with Boomers are
almost necessary to start up an ambush and create a decent distraction.

The Smoker's main offensive weapon is his tongue that makes Gene
Simmons from KISS look normal. Any survivor constricted by the Smoker's
tongue attack is rendered helpless and needs a teammate's assistance in
order to get free. This attack does a modest amount of damage while
pulling the ensnared survivor towards you, but once your victim reaches
you, or gets caught up on something, the damage ramps up a bit. It
still doesn't compete with the Hunter's damage output, but it isn't
anything to laugh at, either.

Because you can drag a survivor towards you, you will ALWAYS want to
spawn behind the survivors. Make them backtrack to rescue their buddy.
There are many situations where you can severely hinder the team by
dragging a survivor over a ledge resulting in an instant incapacitation
as they'll be holding on for dear life while a teammate must first
break the tongue's hold, then help their friend back up. There are also
plenty of locations where you can drag a survivor down to a lower level
resulting in a hefty amount of falling damage for your victim. I will
go into greater detail in the individual map strategies later on in
this FAQ.

Aside from dragging survivors into massive amounts of falling damage,
Smokers can also drag their prey through hazardous areas and into very
dangerous situations. Smokers are great for pulling survivors into
alarmed cars which will draw a large mob of zombies to complicate
things. Smokers are great for dragging a survivor right next to a Witch
which will startle her and cause some serious trouble for the team.
Smokers can pull survivors through fire for additional damage. Smokers
are excellent at pulling a straggler survivor back to an area the rest
of his/her team cannot return to. And Smokers are great for pulling a
survivor away from his/her teammates who were vomited on by a Boomer.

That being said, Boomers are also good friends with Smokers. The Smoker
can yank a survivor away from the team while the rest of the pre
occupied survivors lose track of their comrade. So just like the
Hunter...if you see the team get puked on, aim for a survivor NOT
dripping with stomach acid as it will most likely cause more damage.

Unlike Hunters, Smokers are rather loud because of their constant
coughing and wheezing. And to make matters worse, as their name
implies, they let off a pretty distinct visual cue as well. Green smoke
will follow you wherever you go, and it makes you extremely easy to
find and hunt down in many of the various environments in the game. To
try and combat these downfalls, you need to stay hidden at all costs.
Some maps are better than others when it comes to offsetting your
visual cue. The Death Toll and Blood Harvest campaigns are great for
concealing a Smoker's visual giveaway on the majority of their maps.

Smokers are great when attacking from rooftops. If only your tongue
gets broken, you have a safe and quick escape route you can run to
while you wait for your tongue attack to recharge. Survivors can't see
through thick trees, but you can still see their silhouettes, so keep
that in mind as you may be able to technically attack from "out in the
open" but remain unseen because of the foliage. Just make sure that if
you DO attack from behind trees, that you can still find your way to a
safe spot as those leaves don't provide any protecting cover from the
hail of bullets that will surely be sent flying your way! Smokers also
don't run quite as fast as a healthy survivor can, so if you see a
survivor coming your way and your tongue attack isn't nearly done
recharging, you may as well try and get off a quick claw swipe to do a
little damage before the inevitable happens.

The Smoker's claw swipe does a measly 4 damage. It will take 25 claw
swipes to down a survivor at full health. Yeah...if there's one thing
situational about the Smoker, it's when you want to use your secondary
attack. Last ditch effort to dish out a little more damage before the
inevitable shotgun shell to the face puts you out of your coughing,
hacking, wheezing misery...well, at least for a while.

The Smoker's tongue has a hidden 50 health. A few shots from a pistol
will break your tongue's hold from a survivor. Obviously, being killed
will break your hold as well. But a survivor can also be freed from a
Smoker's tongue attack if a fellow survivor uses his/her melee attack
on the constricted teammate. Fragile enough for you? Well, there's
more. If you get attacked by one of YOUR teammates while constricting a
survivor, it will break your hold.

There is some good that can come from this, however. If you manage to
drag a survivor over a ledge so that they must be helped up by another
teammate, you can have one of your infected teammates attack you to
break your hold and allow you to run for cover. Respawn times are
always longer than waiting for your tongue attack to recharge, so it's
actually beneficial to you by being attacked when your victim has been
dragged into an instant incap.

If you miss with your tongue attack, it will take 3 seconds for it to
recharge. If you connect with the tongue attack for whatever length of
time after the first hit, it will take 15 seconds for it to recharge.
So try to make your attack count. It's not really beneficial to dish
out 3 damage on a single hit and having to wait 15 seconds because
there was another nearby teammate who immediately helped his friend.
You should also know that your tongue takes a short time before it
actually "connects." The survivor will know he/she is being constricted
because of involuntary movement and saliva drops on their screen.
During this short time, the survivor can still shoot, and nothing is
more frustrating than using your tongue attack on a survivor only to be
killed by that same survivor mere milliseconds before your tongue
attack actually took hold. Smokers are best at a distance against
survivors who are equipped with either of the Shotgun weapons due to
their poor long range power and accuracy. However, if you use your
tongue attack at point blank range, the survivor will become instantly
ensnared.

When the Smoker dies, he creates a dark cloud of smoke that obscures
the survivors' vision. It doesn't dish out any damage, however, if a
normal infected scores a hit while inside the smoke cloud, it counts as
an "assist" for you.

Try not to be predictable when playing as a Smoker. Many survivors will
throw Molotovs at alarmed cars in anticipation of you spawning next to
it ready to set it off. Spawn around the corner. Next to a different
car. On a rooftop. On a ledge. Then as the survivors run past the car,
drag one back. That way you may still activate the car alarm, AND the
survivor team used a Molotov for no effect whatsoever.

There are many locations in each chapter of each campaign in Left 4
Dead where the Smoker can be a very valuable asset for the infected
team by exploiting the environment. I will go into greater detail later
on in this guide to point out these areas.

Now go and *smoke* your competition!


**************************************************************
-------The Boomer------- [L4DBOOM]
**************************************************************

"BOOM! Here comes the BOOM! Ready or not!" - P.O.D.

Boomer Specific Achievements:
***Barf Bagged*** - Cover all 4 survivors with Boomer Bile at the same
time.
Pretty straightforward. When all of the survivors are huddled together,
go and spray them! I don't believe this achievement works by exploding
near them, however. You must cover all of the survivors with puke in
the duration of one attack.

***Outbreak*** - Catch a rare strain of infection, then pass it on to
someone else.
***How the Outbreak achievement works***
From what I've heard, a Valve employee gave himself this achievement to
get it started.
It works by being vomited on by a Boomer player who already had the
achievement, then when YOU play as a Boomer, vomit on someone who
doesn't have the achievement yet. The Outbreak achievement is only
available on the PC version of the game.

Primary Attack: Projectile Vomit
Secondary Attack: Claw Swipe
Health: 50

Go and shower your love all over them!
The Boomer's purpose in Left 4 Dead is very simple. SLOW THE SURVIVORS
DOWN.

That's it. Simple logic will tell you that the longer the survivors
stay in the field of play, the more likely they are to die. When you
vomit on a survivor, it acts like a pheromone drawing zombies-a-plenty
to attack the addled person. The Boomer's vomit attack also blinds the
victim, gets rid of any silhouette for fellow survivors that could
otherwise be seen, and creates a loud eerie music for the affected
survivor, thus lowering awareness via audio cue to teammates in
trouble. So naturally, when someone gets "boomed" as it's commonly
called, the team goes into defense mode. They'll normally stop what
they're doing, run towards a corner, toss a molotov or a pipe bomb, or
on some rare joyous occasions, start spamming bullets every which way
in a futile attempt to dispel a mob of zombies surrounding them that
causes more friendly-fire incidents than planned!

Slow them down. All it takes is for one survivor to get vomited on to
stop the team. If you think that you can wait a bit to cover more of
them, DON'T. Boomers are very fragile with an anemic 50 health so
waiting around is usually bad. The Boomer constantly gurgles, belches,
and makes other noises like he belongs on a side show that even the
most twisted person would be hesitant to see. And he makes these noises
rather loudly. He's easy to pick out of a crowd because of his obese
body, and he moves slowly. So that being said, *AND I WANT TO MAKE THIS
PERFECTLY CLEAR*...if you see an opportunity to vomit on a survivor,
TAKE IT. It's 99.999% of the time more beneficial to get one survivor
instead of risking a wasted life because you *thought* you might have
had a better opportunity by waiting.

In the vast...and I mean VAST majority of cases, spawn in front of the
survivor team. A Boomer playing catch-up is more embarrassing than your
mom showing your girlfriend your baby pictures. There are only a slight
few situational cases where it's beneficial to spawn behind the
survivor team, but those cases are usually few and far between.

The Boomer can get the same effect of vomiting on survivors by dying in
close proximity to them as well. When the Boomer dies, he...BOOMS...and
it can be extremely effective against trigger happy survivor teams.

Boomer's aren't necessarily great at dishing out damage, but you will
see how many hits your mob of zombies got on whoever you vomited on by
a counter. These "assists" can be misleading when it comes to damage
output. A normal infected deals 1 to 2 damage per punch, kick,
whatever. Yet, I've had assists well over 50 in a short time that have
done less than 25 damage it seems.

For an incapacitated survivor, being vomited on is a death sentence.
Unless at least 1 other survivor is covering, a horde of zombies
beating on an incapped survivor will *very* quickly take care of the
helpless victim. Don't be surprised if you see an assist over 200 if
you vomited on an incapped survivor.

The Boomer's vomit attack has a 30 second recharge time. Take that into
consideration because you'll most likely get a 20 second spawn time
after dying on a 4 player infected team. If you manage to cover a
survivor or two with vomit, go ahead and try to run into the fray and
explode over more survivors. Chances are you'll respawn faster than
your vomit would have taken to recharge, not to mention you'll be able
to choose where to spawn instead of trying to catch up to the team and
running the risk of dying out in the open.

The Boomer's projectile vomit travels in an arc. Aim upwards for a
little more distance. Problem is, the range on it isn't exactly
fantastic. Odds are you'll die a few seconds after getting your vomit
attack off. Boomers can use their vomit attack from rooftops for a
surprise, though sometimes it can be a bit of a pain to aim. I've found
that jumping down from a rooftop in the middle of the survivor team and
vomiting on them is more effective, but if you manage to get 1 or 2
survivors covered with vomit from a rooftop vantage point, more power
to ya! I should also mention that the Boomer cannot vomit immediately
after spawning. There is a delay of roughly 1 second before you're able
to use the vomit attack. Take that into consideration as you won't be
able to spawn and puke immediately. However, you can spawn, and then
get blown up immediately for the same effect.

The Boomer's claw attack is the same as the Smoker's. 4 damage. Not
spectacular in any way. It will take 25 claw swipes to down a survivor
from full health. The claw swipe comes in handy after vomiting on the
survivors and going into try and explode on more of them. You may get 1
or 2 swipes off before dying, and every little bit helps.

The Boomer's explosion will not "re-boom" a survivor who was covered
with vomit an outline is still purple. You must wait for that
survivor's purple silhouette to change back to green, yellow, or red
before attempting to splash them again.

The Boomer's explosion will stagger back anything around it. Survivors
can be knocked back a few steps. If they're close to a ledge, you can
actually stagger them over the edge resulting in an instant incap which
is needless to say...awesome! However, the Boomer's explosion will also
knock Hunters off their pinned victims. If standing next to a Smoker,
it will cause him to release his grip on constricted survivor. The
Boomer's explosion, however, will NOT knock a survivor off a Smoker's
tongue as long as your explosion doesn't rattle the Smoker. It can even
stagger back a Tank for a few seconds. So keep that in mind when trying
to aide your infected teammates.

If you see a survivor pinned by a Hunter or pulled by a Smoker, vomit
on the survivor(s) coming to rescue their helpless friend. It's much
more difficult to save a teammate when you have to fight your way
through a horde of zombies.

The Boomer's explosion no longer startles a Witch. So don't try to camp
out next to her - you'll be easy pickings! However, the Boomer's
explosion still activates car alarms to my knowledge, so go ahead and
camp there! The Boomer's explosion also instantly destroys nearby
doors, windows, and other breakable obstacles so future hordes will
have an easier time reaching the survivors.

Boomers team up with every other special infected well, but they really
shine with the Tank. During the finales on each of the campaigns, a
blinded survivor with a Tank active spells bad news for their team.
Communicate with your team to save a Boomer's normal spawn (rather than
auto-spawn) on finales for when the Tank is about to show up. It's a
great way to really disorientate the survivor team, and if done right,
you can end the match right then and there because of the ensuing horde
slowing down survivors allowing the Tank to close the gap. It's a
deadly strategy. Try it some time!

Now go out there and have a BLAST!


**************************************************************
-------The Tank------- [L4DTANK]
**************************************************************

"Savior to my own. Devil to some. Mankind falls. Something wicked
comes!" - Iced Earth
You Will Become the Tank!

Tank Specific Achievements:
***All 4 Dead*** - Kill all 4 survivors in one life as a Tank.
Pretty self explanatory. I found the easiest way to do this is by
punching movable objects into them. Another, although much rarer
occurrence in unlocking this achievement is hitting multiple survivors
into a corner and trapping them there. When they're incapped, move on
and get whoever is left.

***20 Car Pile-up*** - As a Tank hit 20 Survivors with a car in the
Crash Course campaign.
Pretty much explains itself. If you become the Tank, do your best to
smash cars into the survivors. Keep at it, you'll get it.

Primary Attack: Punch
Secondary Attack: Rock Throw
Health: 6000

Like the Incredible Hulk with some steroid-rage turned into a
zombie...here comes THE TANK!

The Tank is random. Some maps you'll get one, some maps you won't. The
ONLY time you are guaranteed a Tank is in the finale of each campaign,
in which you'll always get at least 3. A good Tank player can really
rip apart a survivor team. Each hit from the Tank does a whopping 24
damage to the survivors, and you have 6000 health to take them out. The
problem with this is that you are now the primary target. And a big
target, you are. It will take 5 punches to incap a survivor at full
health.

If a survivor gets punched by a Tank, they get sent flying. On one map
in particular, this is extremely devastating to the survivor team as it
can result in instant death. Not incapacitation. Death. These
particular shots are commonly called "Home Runs," and they are more
common than you think on that particular map. I will go into greater
detail about these locations later on in this FAQ. If you hear anyone
say Bob Uecker's famous Milwaukee Brewers Home Run call "GET UP! GET
OUTTA HERE! GONE!!!" you're probably playing in the same game as me.

The Tank's biggest enemy is fire. Unlike the regular campaign mode, a
Tank lit on fire in VS mode actually moves SLOWER. Not faster. Once you
are lit on fire, it starts an invisible 40 second timer. Regardless of
how much health you have left, after you've been a-blazin' for 40
seconds, you die. There are a few locations in the game where you can
put out the fire, but just as a general rule, avoid fire like the
plague if you can. Tanks are far too rare to squander. Sometimes it's
inevitable you'll be lit on fire, and sometimes, the game Director will
really screw you over by spawning the Tank IN FIRE... Sometimes you
just gotta make due with what you have, though.

That being said, it's a common survivor strategy to save a molotov for
when they hear the Tank's music theme playing. Sometimes a survivor
will carry a gas can with him/her for a short while in anticipation of
a Tank. The biggest upside for the infected team when it comes to a
random Tank spawn in the middle of a map that's not the finale is that
he just pops up. There's no listening for the Tank's signature growling
beforehand from what I've noticed.

If you find out that you're going to become the Tank, get ready to
attack the survivors. If you don't, you will lose control of it. A
frustration meter appears on the screen indicating when you'll lose
control unless you attack. If you DO lose control of the Tank, it will
get transferred to another player on your team. If THAT player loses
control of the tank, the AI takes over...which is really bad for the
infected team as AI Tanks enjoy pummeling only one victim and taking
bullet after bullet while it stubbornly tries to kill that single
downed survivor rather than going for multiple incapacitations.

Tanks love corners and narrow hallways. Reason being is because you
have the opportunity of hitting a survivor only a short distance away,
closing the gap, and hitting them again before they can even regain
control of their character. With adequate team support from a Boomer,
you can possibly hit 2 or more survivors into corners and incap them
both. The Tank's punch also hits multiple targets, so the more
survivors in the corner, the better! The downside to this is that it
leaves you no room to avoid bullets. Team co-ordination is extremely
important. There's no shame in waiting or possibly even passing the
Tank onto another player while waiting for teammates to respawn.

The Tank's punch is used for more than just directly attacking.
Outlined in red, you'll see various objects on every map that you can
use to launch at the survivors. Cars, dumpsters, hay bails, tree
trunks, pallet jacks, forklifts, and more. If you punch one of those
objects and it collides with a survivor, it's an instant
incapacitation. If you manage to smash one of those objects into an
incapacitated survivor, it will dish out an extra 100 "bleed-out"
damage, so quick kills are attainable if you have good aim and the
survivor team has split up.

These movable objects can also be used to trap survivors in certain
areas making them unable to proceed and become little more than
turtles. After a while, the object blocking their path will simply
disappear, but it can be extremely helpful in assisting your team. I
will go into greater detail later on in the FAQ and point out many of
these locations.

The Tank's secondary attack is his Rock Throw ability. The Tank rips a
chunk of concrete out of the ground (regardless of what surface he's
standing on) and chucks it long distances. Each hit from a thrown slab
of concrete dishes out 24 damage, but it does not knock back the
survivors. It only knocks them down. If you connect with a Rock Throw
at a modest distance, you can down that survivor long enough for you to
run up and punch them to double up your damage.

The Rock Throw attack takes some getting used to. Just like the
Hunter's pounce and the Boomer's vomit, you'll want to aim upwards for
more distance out of your throw. It takes about a second for the Tank
to actually toss the rock but you can still turn in the direction you
wish to throw it before the Tank actually launches it. For running
survivors, aim slightly in front of them for the best result.

The Rock Throw actually manages some surprising range. It's not
uncommon for a Tank player to just sit back and start chucking concrete
at the survivors while waiting for his infected teammates to respawn.
Whether or not you connect with these tosses doesn't really make a
difference at this point as a lot of survivor players tend to use a
weapon with the greatest accuracy and stand still to shoot at you. You
can take a pretty hefty amount of damage, so if you're a good distance
away, try a few shots at them while your teammates respawn. Then you
can go in and attack in unison.

The Tank's default running speed is SLOWER than a survivor over 40
health. Like any infected, concentrate on the weakest survivor first.
If you are lit on fire, you can still run faster than a survivor under
40 health, but it is a severe problem for you. Don't go chasing around
a particular survivor if they're all healthy. Remember, the Tank is
priority #1 when it comes to the survivor team.

You'll have to rely on your teammates to distract and give you an
opportunity to go in and punch if you're dealing with a team of four
healthy survivors. If you need teammates to respawn and you're NOT on
fire, there's no shame in running away to wait for them. Besides,
running away may give you some good practice with the Rock Throw
ability.

The Tank's punch one-hit-kills Hunters, Boomers, Smokers, and Witches.
DON'T PUNCH THEM! This includes Hunters and Smokers who have a survivor
in their grasp. It will kill YOUR teammate and allow the survivor to
live. Bad idea. You don't have to be a "gentle giant" when playing as
the Tank, but do keep aware of your teammates and their locations.

It's generally the best strategy when playing as the Tank to only go
for incapacitations. Incap one survivor, then move on to the next.
Remember, a survivor doesn't have to be killed to be useless to his/her
team. 4 incapacitations = over.

Now go out there and fight nice!


**************************************************************
-------The Witch------- [L4DWITCH]
**************************************************************

"Now listen up! She's razor sharp. If she don't get her way. She'll
slice you apart!" - Motley Crue

There are no Witch specific achievements on the infected side of Left 4
Dead.

The Witch isn't actually a playable infected character in Left 4 Dead.
However, that doesn't mean you can't take advantage of opportunities
that present themselves when a Witch DOES appear. Like the Tank,
Witches are random. Some maps you'll get one. Some maps you won't. But
UNLIKE the Tank, you are never guaranteed a Witch spawn. I've played
several VS matches in which no Witch spawned through all 5 maps.

If the Witch hits a survivor, they are instantly incapacitated. Then
she starts to shred them relentlessly at a rate of about 50 damage per
second. (So with a bleed-out health max at 300, it takes about 6
seconds for the Witch to finish what the survivor started...)

The Witch can be startled in several ways by survivors.</pre><pre id="faqspan-2">
1) She can be startled by being shot.
2) She can be startled by being hit with a melee attack.
3) She can be startled by simply looking at her for too long.
4) She can be startled by a flashlight shined on her too long.
5) She can be startled by staying close to her for too long.
6) Molotov Cocktails get her angry.
7) Pipe Bombs too...

1) Being Shot
If nobody on the survivor team is comfortable with "Cr0wning" the Witch
(One hit killing with a head shot from a Shotgun type weapon), a common
strategy is to have one person shoot her and then run away. The Witch
will only go after the person who startled her. This strategy is called
"pulling" and it can be extremely frustrating for the infected team as
it can result in a safe neutralizing of the Witch and thus not allowing
you and your team to take advantage of her spawn. You can try to combat
this by employing the following strategy, though with some
stipulations.

+ Have a Hunter crouch in front of her. If the survivors are still
using "tier 1" weapons (Normal Shotgun and Uzi) accuracy becomes an
issue. Every gun has a piercing quality to it, meaning bullets will
travel through their first target and hit whatever was behind them. If
the survivors are taking aim at you, they'll most likely startle the
Witch, and then have a whole new problem to deal with. If they DO
startle the Witch in this sense, odds are they'll stop attacking you.
This can allow you to attack in unison with the Witch and cause some
havoc. If the survivors are using "tier 2" weapons (Auto-Shotgun,
Assault Rifle, Hunting Rifle) beware of that dastardly Hunting Rifle.
It's accuracy is unmatched, it dishes out tremendous damage, and it can
ruin the whole strategy. Be aware of which weapons the survivors are
using. If you notice a Hunting rifle, don't bother with this tactic. If
a "pull" is successful, fear not for there is still a slight glimmer of
hope. Remember when I said that Boomers should always spawn in front of
the survivors? Well, this is one of those rare situational cases where
it's beneficial to spawn behind them. If someone pulls the Witch and
then starts running away, vomit on them! When the survivors have to
fight their way through a mob of zombies with a Witch on one of their
tails, it's not pretty...well, for them at least. +

Everybody loves a failed "Cr0wn." 90% of the time, a failed Cr0wn
results in an incap for the survivors when using the Auto-Shotgun. And
100% of the time, a failed Cr0wn results in an incap when using the
normal Shotgun (Unless assisted by teammates. Then that 100% drops to
about 95%). If you see a failed Cr0wn, pounce, drag, or vomit on any of
the other survivors as soon as possible. The Witch will deal with the
one who disturbed her, and if you can hinder the other 3 survivors, it
can get messy for them. Remember, an incapped survivor is only able to
use pistols at about 1/2 normal firing speed. Witches usually work
quickly enough to take a big chunk of bleed-out health away if not
outright kill them.

Stray bullets can be amazing when it comes to Witches. Because most
survivor teams like to plan what they're going to do with a Witch
that's in their way, pulling the Witch with a stray bullet completely
interrupts their train of thought. While you, on the infected side of
things, can't really co-ordinate a plan with your teammates in only a
matter of a second or so, do realize that this presents an amazing
opportunity for a solo attack on your part if you're a Hunter or
Smoker. Find out who the Witch is going after and pounce or pull
him/her. Slow that person down just enough for the Witch to catch up
and incap.

2) Being Hit with a Melee Attack
It doesn't happen often, but usually when it does, it's because of
someone randomly spamming melee attacks while blinded by a Boomer's
vomit. Because there's a horde of zombies already around, it makes
things pretty nasty for the survivor team. This is where the whole
"pounce or drag whoever wasn't vomited on" tactic comes into play.

3) Looking at Her for too Long
The Witch doesn't like people who stare. This doesn't happen very
often, but for people who take too long lining up a shot trying to
Cr0wn her, or weren't aware of her presence for whatever reason, she'll
swat them down quickly. This usually happens with one survivor, and the
rest have either moved on, or are hanging back. If you're a Boomer and
you see someone staring at the Witch lining up that perfect Cr0wn shot,
vomit on him/her! Mob of zombies + Witch + can't see where you're
going/aiming = OUCH!

4) Shining a Flashlight on Her
You'd be surprised how many people forget to turn their flashlights off
around the Witch. It's hard for you to tell when you're playing as the
infected, but if you hear the Witch getting angry and the survivors are
a little ways away from her, assume it's the flashlight. Some people
don't even realize that their flashlight is on. This is the other rare
occasion where if you're playing as a Boomer, spawn behind the team.
This works almost identically to "pulling" the Witch.

5) Staying Close to Her for too Long
Witches really don't like survivors being close to them for any length
of time. If you're playing as a Smoker, and a Witch is a little out of
the way of the survivor team's path to the safe house, try dragging one
of them right next to the Witch. It will startle her, AND usually it
won't break your hold. So you'll take the survivor down even faster as
there's the constricting damage from you, and the shredding damage from
the Witch working together.

Survivors don't have to be directly looking at her for the Witch to be
startled. Just being in close proximity to her is enough to get her
growling, then screaming, then attacking. Boomers...take advantage of
this. Tight corridors and narrow hallway areas are the ideal scenarios
for this. It works the best if the Witch spawns in a room off to the
side, such as one of the many in The Hospital level in No Mercy. The
Witch *can* be startled even if a wall separates her from the
survivors, so keep that in mind as well.

6) Molotov Cocktails really Burn Her Up
Like the Tank, setting a Witch on fire starts an invisible timer. Only
for the Witch...it's 15 seconds. Not 40. The Witch runs slower when on
fire, and it's a common strategy for survivor teams to light her up
from a vantage point if she's on a lower level. There really isn't much
you can do to combat this. However, I rarely see people lighting up
Witches with Molotovs. You have to weigh the pros and cons against each
other here. Witches can be avoided, they can be dealt with in other
ways that don't waste a valuable throwing weapon, and it generally
slows the team down by lighting her on fire. Truth be told, lighting
the Witch on fire from a distance is generally the best way to take
care of her, believe it or not, as any other special infected around
her may also get lit up while thinking of ambushing them by the Witch.
Use the Tab key (by default) to monitor what items the survivors have
in their possession. If you see Molotovs, think twice about employing
that tactic in #1 in this section. The reason many people don't use
Molotovs on the Witch is because it takes longer. That's it. Even
though it *is* usually safer.

7) Pipe Bombs Have a Larger Blast Radius Than You Think
It's a common survivor strategy to toss a pipe bomb to draw out any and
all normal infected before attempting to Cr0wn a Witch. However, if
that Pipe Bomb blows up in close proximity to the Witch, she WILL be
startled, even if she wasn't actually in the blast. I've done a bit of
research testing the range of a pipe bomb's explosion. If a Smoker's
tongue at max range over a flat surface is 100 feet (as indicated in
the 'Big Drag' achievement) then a pipe bomb's damage radius is roughly
20 feet. If you hear the pipe bomb's distinctive beeping, and it's kind
of close to that Witch, get ready to attack because she's not going to
like what's about to happen! These poorly thrown pipe bombs are few and
far between, but they're a nice treat for you and your team when they
happen.


**************************************************************
-------General Tips------- [L4DI]
**************************************************************

There are certain things in Left 4 Dead that apply no matter which
infected character you're playing as. These boil down to common sense
in most cases, but some rely on backwards logic as well.

1) NEVER assume anything. The person who acts predictably usually ends
up dead. This applies to both the survivors AND the infected. Stay
hidden. If you're going to spawn as a Smoker or Boomer, don't spawn
until you're ready to attack. Their audio cues are loud, the Smoker has
a visual cue, and people can find you more easily - resulting in you
dying more easily. If you plan on attacking from a common ambush
location, save your spawn until you're ready to make your move.

Never assume that the survivor team will panic if things start to get
chaotic either through a random horde, or one summoned by a Boomer's
vomit. Not every survivor hit by a Boomer's puke is going to start
spamming bullets every which way. They may not act irrationally once a
Tank comes into their line of sight. Just make sure you're ready to
attack once you see one of the survivors slip up.

2) Support your teammates! Attacking solo, unless you know you can get
some good damage out of it, is bad. Always try to attack in unison with
your teammates. Sometimes your infected team will have three Hunters
and a Smoker. This means that all four of you can each take a victim
and stop the survivors right then and there with a well co-ordinated
attack. 3 Hunters and a Smoker is commonly called a "3-1" though I
prefer to name it a "Death Squad." It just sounds cooler!

3) Common sense will tell you that nothing can come out of an empty
room. Be uncommon. If a survivor checks a room, then abruptly leaves,
spawn in that room and attack them from it. This works great as any
type of infected, but is usually the best with Hunters and Smokers.
Boomers may be too fragile to risk playing catch-up in wide open areas.

4) Communication is key! Plan your attacks, and tell everyone what
you're doing. Using a microphone is best, unless the "all talk" feature
is on for that particular server. Speaking is generally always better
than typing, but even if "all talk" is enabled, you can chat with only
your team by typing. Make sure everyone knows what you're doing, and
offer suggestions to your teammates so that they may compliment your
own attack.

5) Use the environment to your advantage. Ledges, rooftops, narrow
corridors, mezzanines, bridges, etc can all be used to the infected
teams' benefit. Use the distractions from Crescendo Events whenever you
can to dish out some extra damage, but make sure you can attack again
immediately after the survivor team starts to move on. Time your
attacks well, and you can keep the pressure on them.

6) Go after the weakest person. Incapaciting a survivor will slow the
rest of them down for 5 precious seconds. This can give your teammates
a chance to respawn, or move into position for a better attack.

And be sure to stay after that weakest person. Remember, a survivor can
only be revived from an incap twice before "going black and white."
When a survivor is seeing black and white, they must be healed in order
to stay alive after their health reaches 0 again. They're also moving
slower because the health they receive after being incapped is only 30,
and it's bleed-out health, so it's slowly dropping. Remember, the
hardest part of stopping the survivors is getting that first kill. Once
you do that, it makes your task exponentially easier. A black and white
survivor at 1 health is still able to spam bullets from their Auto-
Shotgun. An incapped survivor has horrible aim, two pistols, and can
only fire at about 50% normal speed at best. And a dead "survivor"
can't do a darn thing!

7) Look at what the survivors have coming up. Once you die and are
waiting to respawn, press the SPACE bar (by default) until you enter
spectator mode. This will allow you to zoom around the map and notify
your teammates about what the survivors have around the next corner as
far as goodies go, and it can help you in locating a nearby Witch for
your team to take advantage of.

8) Grind the survivors down whenever you get the chance. There are
various areas where you can keep the survivor team occupied for much
longer than they want to be. Some of these locations are at a safe
room's exit at the beginning of the level. Remember, if the survivors
haven't left the safe room yet, you will instantly respawn after dying.
With constant hordes from fast-spawning Boomers, and repeated claw
swipes from Hunters and Smokers, you'd be surprised how much damage you
can do right out of the chute! I will go into detail to point out the
common "grind" locations in the individual map strategies.

9) High ground is an advantage. Really...it is! It provides additional
distance for Hunters. It usually provides more cover for Smokers. And
an uncommon attack angle for Boomers. Thing is, most people (and by
'most' I mean the vast majority) when entering a new area have a
tendency to check left to right before they check up and down. Unless
you have to attack from ground level, ALWAYS try to stick to the high
road.

-------Other Infected Achievements------- [L4DACHIEVE]
**************************************************************

Since the character-specific achievements were listed in the individual
character description sections, this part of the guide will deal with
the other achievements that are part of the zombie side of Left 4 Dead.

***Dead Wrecking*** - Dole out 5000 total survivor damage as a special
infected.
This achievement is pretty self-explanatory. Just keep playing VS mode
and keep dishing out damage to the survivors. You'll get it eventually.
The fastest way to get this achievement is by hitting movable objects
into the survivors when playing as a Tank. It dishes out tremendous
damage!

***Lamb 2 Slaughter*** - As an infected, incap a survivor who has
entered and left a safe room.
Again, pretty self explanatory. This is most easily done by having a
survivor get incapped near the safe room door and as one of his/her
teammates comes to the rescue, incap THAT survivor. The rescuing
survivor, as one would expect will need to be near death (probably
having no more than 30 health) before leaving the safe room and
attempting to revive his/her teammate. Like most of the other specific
infected achievements, this one relies a lot on the opposing team
making mistakes. It can be pretty hit-or-miss achieving Lamb 2
Slaughter as you'd be surprised at how many people would rather let
their teammate die mere inches from the safe room door!

***Truck Stop*** - Your team wipes all Survivors after the escape
vehicle has opened in Crash Course.
This one is tricky, and more dumb luck than anything. First and
foremost, you need a survivor team that is good enough to last the
entire duration of the finale, but stupid enough to try going back out
to help up an incapped survivor or two after the vehicle has descended.
Then, co-ordinate with your teammates to pounce or pull any other
survivors that may be coming to the rescue. Incap them all to get this
achievement.

***Wipefest*** - Your team incapacitates three Survivors within five
seconds in the Crash Course campaign.
This is another achievement where the luck of the draw may be more
useful than actual skill. You need at least three survivors at low
health, and a well co-ordinated attack from your teams' Hunters and/or
Smoker. The window of opportunity is very narrow here. I found that
this achievement works well in tandem with the Truck Stop achievement.

-------No Mercy Overview------- [L4DMERCY]
**************************************************************

No Mercy is one of the most often played VS maps in Left 4 Dead. It's a
very well balanced campaign for VS mode, there aren't many 'broken'
areas for either side, and it has the most popular finale event of all
4 campaigns.

No Mercy starts out where the intro movie of Left 4 Dead ended. The
survivors start on the rooftop of an apartment building, and their
ultimate goal is to reach the rooftop of Mercy Hospital so that a News
Station Helicopter can rescue them.

For the infected, No Mercy has proven to be a favorite because of it's
many locations for big damage pounces from Hunters, areas with fall
damage and instant incap locations for Smokers, plenty of angles
Boomers can attack from, and lots of movable objects for Tanks. No
Mercy has three major Crescendo Events apart from the finale, though
one of them is quite frustrating for infected players and has been
called to be patched several times over to no avail as of yet. None of
the Crescendo Events, however, can be rushed through by the survivors.
Each one forces the team to wait a short time and fight through a mob
of zombies.

The most notable location No Mercy has been altered to offer balance
between the two sides in VS mode is the rooftop in the finale. The
campaign mode offers a sheltered area with 2 doors connecting a
stairway on the platform that has the minigun. The VS mode alteration
is one door leading to an outdoor staircase behind the minigun. This
makes it more accessible for Boomers, Smokers, Hunters, and Tanks
alike. And seeing as how many survivor teams camp out on top of that
platform, the change is a welcome one for the infected.

Aside from the Hospital map in No Mercy, it's a pretty dark campaign.
It takes place at nighttime, during a rain shower. Because of a
generally dark background, Hunters can find it easier to perch high up
without putting out an easily spotted silhouette against the
backgrounds. Smokers, however, have a lack of thick foliage to hide
behind, and the green smoke they give off doesn't blend well with ANY
environment in No Mercy. There are, however, many rooftops in the first
and third maps of No Mercy that offer adequate cover and escape routes
for Smokers to take advantage of. No Mercy is also the home of one of
the most survivor embarrassing, although rare and difficult to pull
off, moments for Smokers to take advantage of.


**************************************************************
-------The Apartments------- [L4DMERCYa]
**************************************************************

Right from the get-go, the survivor team must make a decision. There
are 2 ways they can enter the apartment building. Through the door, or
through the skylight. Many teams prefer to just enter through the door,
but...

*SMOKER TIP*
*HUNTER TIP*
For both Smokers and Hunters, there is a building to the right of where
the survivors start off. It's a great place to spawn, as you can just
jump onto the building the survivors started on if needs be. If the
survivors choose to take the skylight entrance, spawn immediately and
try dragging or pouncing on any straggler left on the rooftop. This
will force the rest of the team to backtrack to rescue their friend
while you dish out more damage immediately. If you're the Smoker, you
can stay on the rooftop you spawned on and retreat back if your tongue
is broken. Hunters here can manage pounces of over 12 damage quite
easily with a little practice. Any additional shredding is just gravy
after that. It's not uncommon for Hunters to incapacitate a survivor on
the rooftop if a well co-ordinated Boomer attack like the one below
occurs.

*BOOMER TIP*
Regardless of which entrance the survivors take into the apartment
building, a great Boomer location is behind the breakable wall just
past the kitchen area. You can break the wall with one melee swipe,
then vomit over as many survivors as you can. If a survivor gets pulled
or pounced on the roof, causing a horde to immediately follow the
rescuing survivor(s) can really slow down things and result in massive
damage to one of them.

As the survivors make their way down another level, there are many
rooms that can contain goodies such as molotovs, pipe bombs, pain
pills, med kits, or a 2nd pistol. Remember you can always hit the Tab
key (by default) to monitor which survivors are carrying items. The
survivors will eventually reach a hole in the floor that will put them
on ground level.

*SMOKER TIP*
A straggler here can spell a kill for the infected team. After 3
survivors jump down the hole, try and pull the last one back to
complicate things. Make sure you're back far enough to stay out of the
way of other survivors jumping and spraying a few bullets your way. I
believe that the survivors can also shoot through the floor, but a lot
of them don't and figure their teammate is a goner, so they move on.
Getting a kill is always satisfying! If there is a Hunter nearby, have
him pounce on the survivor you pulled as he'll make the kill much
faster, and it allows you to disrupt and pull apart the team later on
in the level.

*HUNTER TIP*
As the survivors leave the apartment building on ground level, it opens
up a LOT of opportunities for big damage pounces (20+ damage on
contact). One of the best locations to land one of these monsters is as
the survivors just peek through the doorway leading to the alleyway.
The building you spawned on at the beginning is where you will want to
set up. There is also an outside zig-zag staircase across the alleyway
that you can pounce onto, and you can get a 20+ damage pounce from
there as well. The problem is that you spend more time in the air
coming at the survivors, and are therefore you're easier to pick out of
the sky before you land. Best to pounce from the rooftop. You can still
land a 25 damage pounce from there rather easily with the right aim.

*BOOMER TIP*
This is one of those rare occasions where it's wise to spawn behind the
survivor team. Many survivor players are hesitant to head outside
fearing an ambush, so they bide their time a little too long. Long
enough for you to close the gap and vomit on at least one of them!
That'll teach them to wait!

*TANK TIP*
While getting a Tank on this level is rare, it DOES happen. If a Tank
spawns when the survivors aren't far away from the exit of that
apartment building, a common strategy is to run back inside. There are
a few cars that you can punch in that alley and if you hit them just
right, you can actually block the exit to the apartment building,
trapping the survivors in there for a while! Now that the survivors are
temporarily trapped, your teammates can start grinding down the
survivors little by little until the car blocking the doorway
disappears. You can also climb up the building and come in from behind
the survivors by making your way down the same path the survivors took
for a surprise!

There are many rooftops along the alleyway that Smokers just love as it
allows for a quick escape route should their tongues be broken. All
throughout the alleyway until the survivors reach the street, Hunters
can land big pounces. Boomers can vomit from the rooftops as well, and
then jump in after they vomit to try and cover more of them.

*HUNTER TIP*
It takes a rather long time to set up and getting the correct timing
and aim can be difficult, but the angle from which you pounce is
unexpected, it's a guaranteed 25 damage pounce if you land it. From the
building the survivors started on, across from the door leading down
into the apartment building, you can see a tall zig-zag staircase
across the street. Pounce onto that staircase and take it to the top.
From up here, you have amazing range on your pounces. If you angle your
pounce correctly, you can land on a survivors as they're crammed in the
alley between the two buildings. There are obstacles (like other zig-
zag staircases) that you will need to be sure you don't land on, but if
you land a pounce here, it's 25 damage guaranteed. Otherwise, you could
wait until the survivors reach the street and go for a pounce as they
round the corner. It may be slightly less damage, but that's nothing to
pass up. Like I said earlier, though, this location takes a bit of time
to get set up at because you are forced to spawn, then pounce, then
take the staircase up about 6 levels. Make sure you're going to be able
to set up before the survivors reach your ambush location.

Once the survivors reach the street, there are three ways they can go.
The most common way is to enter the building immediately to their right
and head into a small room containing a first aid box. The only special
infected that is useful here is the Boomer as it can slow the team down
and maybe dish out a little bit of damage. From inside that building,
the survivors have a good view of the street and the alarmed car. If
they picked up a molotov cocktail earlier in the level, a common
survivor strategy is to launch the molotov at the car from inside the
building. At that distance, it doesn't active the car alarm, and if a
Smoker was hiding behind it, he'll be dead. So if you're a
Smoker...WAIT to spawn behind that car if you can. Or spawn around the
corner. You can also enter the building immediately to your right
(facing the building the survivors are in) of that car and camp out in
there until the flames die down, or the survivors look vulnerable.

*HUNTER TIP*
You can climb up the building the survivors are camping out in. On top
of the roof, you can pounce up to a higher level, and then if you
pounce at the roof to the right of you, you can walk along an invisible
wall. Turn around and wait for the survivors to leave the building. You
can land a pounce ranging from 18 to 25 damage from there. You can also
sit on the building the survivors are in to pounce them as they're
about to enter the subway. I prefer the former as it's less expected
and is more likely to succeed.

The second way the survivors can go is by staying on the street and
just rushing through without entering the building. This leaves them
open to big damage pounces the entire time.

*HUNTER TIP*
By the flaming oil tanker, you can use wall pounces to reach the roof
of that building and walk along an invisible wall. From there, you can
position yourself on one of the white outcroppings for a good vantage
point with lots of range and no obstructions in your way.

The third and least common way the survivors can go is by staying far
to the left after leaving the alleyway and taking the back path. It
leads to a wide open area, which Boomers aren't particularly fond of,
and there aren't many spots a Hunter or Smoker can effectively attack
from. This is actually the safest route to take, but it's passed up by
many players because it takes longer. The building they enter at the
end of the open area may have some goodies for the survivors to pick
up, and it can really disorientate an infected team setting up for the
survivors to enter the building or staying on the street.

*BOOMER TIP*
If you're the Boomer and you haven't spawned, find which way the
survivors are going first. If they take that back path, spawn in the
building they're heading to and try vomiting on them. This may open up
an opportunity for the Hunters and Smoker on your team to attack.

*HUNTER TIP*
If the survivors take that longer left-side path, once they leave that
building, they'll be in a wider open area. There is a telephone pole
that you can wall pounce up on top of. It takes a bit of practice to
get into position, but a lot of survivor teams for whatever reason tend
not to check up there. Seems they're more concerned with an attack from
behind, or from directly above them after leaving the building.

Regardless of which path the survivors take, they must pass an alarmed
car on their way to the subway. It's common strategy for the survivors
to launch a molotov at the car from a distance so they won't set the
alarm off. Spawn further away from the car if you're the Smoker and
after the flames die down, try pulling one into the car. The horde that
comes from the car alarm is rather large, and the ensuing chaos opens a
bit of opportunity for every infected player.

*TANK TIP*
Again, getting a Tank on this level is quite rare, but it DOES happen
from time to time. Just like the strategy of knocking a car up the
alleyway to block the exit to the apartment building, you can trap the
survivors in the field of play for a short time if you can manage to
punch the alarmed car down the stairs leading to the subway, thus
blocking their path. Punching the alarmed car (and any alarmed car for
that matter) will permanently disable the alarm, just so you know. But
if you can trap the survivors on the streets, you make it easier for
your infected teammates to grind them down through attrition. The car
WILL disappear after a while, so make sure you know when it does. Be
prepared to be called a "noob, hacker, idiot" or any number of racial
slurs should you trap the survivors. You can just laugh at them.

Down the stairs to the safe room allows for one last ditch effort
ambush from behind the boxes. If the survivors made it this far, odds
are they'll make it to the safe room. All you can really do at this
point is try and dish out a little more damage to lower their score.


**************************************************************
-------The Subway------- [L4DMERCYb]
**************************************************************

Immediately after exiting the safe room, an ambush should take place!

*SMOKER TIP*
Immediately to the left of the safe room is a climbable pipe leading to
a platform you can spawn on. The window of opportunity you have here is
rather small, but if you can manage to hold up the survivor team for a
few precious seconds, you allow the Hunters on your team to move in and
dish out some damage.

*BOOMER TIP*
There are 2 locations a Boomer should spawn at the beginning of this
map. The first location is below the safe room in the area with the
pillars. Vomit on them as soon as they drop so that your teammates can
jump into the chaos. The other location is at the top of the escalators
in the middle of the two paths. The survivors can choose to either go
down the stairs, or drop through a vent to enter from the other side.
Spawning in the middle of those two paths allows you to puke on them no
matter which route they take. If your teammates attacked immediately as
the survivors left the safe room, vomiting on the survivors here should
slow the survivors down long enough for your teammates to respawn. I
prefer the latter strategy, myself.

*HUNTER TIP*
Spawn beneath the safe room in the area with the pillars. Regardless of
whether or not the Boomer on your team spawns alongside you, it's
possible to dish out a little damage right from the get-go. If the
Boomer on your team tried the 2nd strategy listed above, you *should*
be able to respawn in time to attack them again before they even reach
the escalators.

Down the escalators, the survivors will enter a more open room with a
few booths that can contain medpacks, pills, molotovs, or pipe bombs.
There is also a table next to the booth on the left that sometimes
contains the "tier 2" weapons. Because most of this map is cramped,
don't count on anyone grabbing the Hunting Rifle. This map is much
longer than the first map in No Mercy, and a gun rack is available
after the crescendo event should any of them wish to switch. Keep that
in mind as you may need to adjust your strategy.

There are two ways the survivors can head up to the actual subway,
though most teams choose to head to the right and go through the subway
car as it provides shelter from Hunters.

*HUNTER TIP*
If the survivors DO head into the subway car, you can actually stay
outside, jump, and claw at them for some pot shots. If you crouch after
each swipe, you force the survivors to fire blindly through the doors.
If you can manage 3 or more claw swipes, great! My personal best here
is 7 against a particularly inept team before I pounced one of them
after they finally got fed up and exited the car.

Regardless of which path the survivors take, they must pass by an open
fire.

*SMOKER TIP*
There is a hole in the wall that 99% of survivor teams never enter
across from the fire pit. You can pull survivors into the fire with
your tongue for extra damage.

The tunnel to the right of the main path provides a nice place to spawn
as most survivor teams just ignore it. It bypasses a train car that can
contain goodies, and a table that may contain an extra pistol, tier 2
weapons, or both. Use this to your advantage as you can have a
troublesome time spawning while the survivors are between the subway
cars.

The survivor team will have to enter a string of subway cars before
reaching a room with a little more breathing room. There is a table
here that may contain tier 2 weapons, and the room across from the
table often contains molotovs, pipe bombs, and a health pack.

*TANK TIP*
In conjunction with a Boomer's horde, the subway car provides an
excellent choke point. If your infected teammates can block the
survivor's path from the rear while you close in from the front, you
may be able to bottleneck them and score several hits resulting in
incapacitations.

The survivors must head up a staircase and enter an area usually filled
with plenty of infected. It's rather difficult to attack the survivors
at this point as they'll toss a pipe bomb to make their lives easier
while they all hang back in the hallway above the stairs. When they
enter that room, the pillars provide plenty of cover to hide and spawn
behind, and Hunters can co-ordinate a decent ambush with no real rhyme
or reason to it. You'll want to save your Smoker here, however.

*SMOKER TIP*
After the survivors head up another staircase past the room with the
pillars, there is a room off to the side that contains a first aid box.
However, there is also a hole in the floor that you can use to drag one
of them down to you, forcing them to make the trip all over again. If
no survivor comes down to escort their teammate back to the rest of the
party, it opens up...

*HUNTER TIP*
..a GREAT opportunity to dish out some serious damage as the survivor
on his/her own tries to re-unite with the team. Land a pounce away from
the others' line of sight - and therefore line of fire -, and you'll
force the survivors to backtrack.

This room is home to the first of three major Crescendo Events in No
Mercy. The Generator Room switch must be activated in order for the
survivors to progress. This process takes roughly 90 seconds, and
forces the survivors to fight off a horde...and your infected team. The
place most survivor teams use to stake out is the corner underneath the
walkway to the right of the mounted machine gun. There are usually a
couple of gas cans that they'll ignite at a safe distance and take care
of the horde. The tables at the entrance of the room usually contain a
generous amount of molotov cocktails, and you can bet that at least one
of those will also be thrown after the fire from the gas cans goes
away. This section of the map can be rather frustrating for the
infected team, as all of the survivors are tightly packed together and
spamming their melee attacks that will disrupt a Smoker's tongue
attack.

*SMOKER TIP*
Sometimes, you can get your tongue attack to work and pull a survivor
through the fire the survivors will undoubtedly have blazing for some
extra damage. Don't count on this always working, and if your tongue
attack gets disrupted, hide behind one of the generators until it
recharges.

After the event, the survivors will head up a staircase and enter a
room that will contain tier 2 weapons and ammo. They will also pass by
another gas can which many survivor teams will ignite by the door to
buy themselves time from spawned infected players.

*SMOKER TIP*
There are gaps in the railing from the walkway above. You can drag one
of the survivors down and slow the team down a little bit here. It
won't cause much (if any) fall damage, but any Hunters on your team can
take advantage of the survivor once your tongue hold is broken.

The many rooms on this upper level past the generator room often
contain plenty of goodies. Molotovs, pipe bombs, med packs, and pills
commonly spawn here. And the survivors usually are pretty tightly
bunched here. However...there are some areas you can use safely to
attack.

*BOOMER TIP*
From out on the street, your vomit can hit survivors who stray too
close to the windows.

*SMOKER TIP*
From on the street, you can drag a survivor out of the windows causing
some fall damage and opening up opportunities for the Hunters on your
team to attack.

The survivors can leave this building in one of three ways.

1) The back alleyway. Actually the safest way they can take, and not
the longest. There is a pipe that Hunters can climb up and pounce from
for big pounces here, however.

2) The front door. The longest route, and it puts them on the street
with plenty of cars for...

*TANK TIP*
Yeah...plenty of cars. Pound away. Just make sure not to punch the
alarmed car near the safe room. The common survivor strategy is to just
run back inside the building they came from. A Boomer here to slow them
down is extremely helpful as odds are you'll be set on fire. This level
of No Mercy is particularly generous when it comes to providing the
survivors with molotovs.

3) Out the windows. Either from the front or in that back alleyway.
Survivor teams that jump out the windows cut down on your reaction
time, and are generally the fastest route to the safe room just down
the street.

Eventually, the survivors will have to pass through a wide open area
that provides LOTS of places for Hunters to land huge pounces. There is
also an alarmed car that Smokers can take advantage of, unless a stray
bullet sets it off. Boomers can spawn in one of the rooms inside the
building the safe room is in for a last ditch effort in slow the team
down long enough for teammates to get a last attack in, but if they
make it this far, all you can hope for now is a little more damage to
lower their score.


**************************************************************
-------The Sewer------- [L4DMERCYc]
**************************************************************

Right from the get-go, you can ambush the survivors.

*BOOMER TIP*
If you exit the safe room spawn point and run to the left, you'll see a
pole that you can climb up. This will put you directly on top of the
survivors, and you'll be able to spawn immediately after they leave the
room. The common survivor strategy here is to run straight ahead to get
shelter from other attacks, but you should still be able to vomit on at
least one of them as they leave the safe room.

*SMOKER TIP*
From the safe room spawn point, run to the left, and you'll see a
climbable pipe leading to a low roof, and another climb point onto
Burger Tank's roof. Turn to face the safe room, and you'll see a zig-
zag staircase on the opposite side of the alleyway. You can jump onto
this staircase, take it to the top, and get a great vantage point
directly across from the safe room exit. If you can manage to get your
attack off and hold one of the survivors in place, you open up an
opportunity for...

*HUNTER TIP*
..a Hunter on your team to make a huge pounce. Hunters can take the
same spawn path the Smoker took, but stop on the roof of Burger Tank.
You can arc a pounce over the roof the Boomer spawned on in this
strategy - just to the right of the staircase the Smoker used to get to
his spawn location. My personal best pounce here was 22 damage. Not a
bad start for 2 feet out of the safe room! If you can land anything
over 18 damage, kudos to you!

Most survivor teams, immediately out of the safe room will take the
straight path into a storage room. There are usually goodies in there
for them, and it provides a little shelter from Hunters and Smokers. If
you are a Boomer, try to keep them in there for as long as possible.
Amidst the chaos from the ensuing horde, Hunters can manage some melee
swipes. It's rather dark in there for the Survivors, so you have that
going for you as well. I wouldn't recommend pouncing them in this area,
as the silhouettes from a pounced victim are still clearly visible.

On the other side of that storage room, there is a garage that can
contain pills, med packs, molotovs, pipe bombs, and tier 2 weapons. The
survivors must now trek down a long and narrow alleyway with tall
buildings lining either side...it's a Hunter's paradise.

*HUNTER TIP*
There are 2 air conditioning units you can use for a hiding spot and
good pounce location as the survivors leave the garage. You can also
set up on the roof above the moving truck and cable spools. Both of
these locations offer a good opportunity for 25 damage pounces. If you
fail to land a pounce, and can recover, you can wall jump back to
safety and try again.

*BOOMER TIP*
There are rooftops you can jump down from after you try vomiting on the
survivors as they pass through the narrow alleyway.

*TANK TIP*
Sometimes, you'll get a Tank on this map right away. There are a couple
of cars you can use to bash into the survivors, and there are plenty of
dumpsters to smash around. The narrow alleyways allow for hordes of
zombies summoned by the Boomer on your team to block the survivors'
paths and give you a good chance of catching up to them. Odds are the
survivors will only have tier 1 weapons here, also...so you can take
advantage of their (moderately) low damage output. Remember, if you
need to, you can always run away to let your teammates respawn. No
sense in going it solo if you don't think you'll do a good job.

The survivors must make a left turn and head down yet another narrow
alleyway that offers many of the same perks for the infected team that
the first one did, though it is much shorter. The survivors will then
enter the kitchen area of Burger Tank. Here, they may find all sorts of
goodies, but many survivor teams are iffy about charging out into the
wide open area here first...and for good reason.

*HUNTER TIP*
Directly across from Burger Tank's entrance is a building you can climb
to the top of. It offers an excellent vantage point of the area, and as
they're leaving the restaurant, you can land a 25 damage pounce from
there. A Smoker who can pull one of the survivors back from the rooftop
of that diner can provide an easy target, and you will dish out more
damage than the Smoker could have on his own. Since the survivors are
generally all grouped together here, it's actually beneficial to the
Smoker on your team as you'll allow him to not only run away and let
his tongue attack recharge, but he can set up for another ambush
location immediately.

The most common action the survivors take once in this area is to blow
up the gas station. It looks awesome, and it provides an easier route
to a building that can contain goodies and tier 2 weapons. It's a
rather common stop for the survivor team on their way through the map,
and it opens up a good opportunity for the infected team to separate
and tear down the survivors.

*SMOKER TIP*
Did a Hunter interrupt your tongue attack at Burger Tank's entrance?
Well, you can run back into the alleyway and head down by that truck
with the cable spools by it. Try dragging any survivor that wanders too
close to the windows and you can pull them all the way back to you,
forcing them to remake the trip...and what a trip it is. So much so,
that if no other survivor comes to escort the pulled victim back to the
rest of the party, a Hunter on your team can land a pounce and possibly
get an incapacitation.

That building isn't necessary to visit, but many teams do, and as they
go to activate the scissor lift, they make themselves vulnerable to big
pounces from Hunters.

*HUNTER TIP*
You can get on top of the building the survivors visited. There is a
water tower on top of that building you can pounce on and it offers a
spectacular view of the area. It provides some cover, I haven't noticed
too many survivor teams checking that area, and the distance you can
get out of your pounces is amazing. You can reach the barrel that's on
fire, EASILY.

The scissor lift is the 2nd major Crescendo Event in No Mercy. On top
of summoning a horde, the survivors must traverse very treacherous
terrain...an awning overlooking the truck depot below. It's a common
survivor strategy to start the lift, and then huddle into the nearby
corner behind it. If the team does that, it makes attacking them more
difficult, but it also keeps them in the field of play longer. The
horde that gets summoned by the event is rather large, and has 2 main
waves. A Boomers can drop down in front of them to try and get a vomit
attack off, but sometimes you'll end up just jumping into a line of
bullets and accomplish nothing. If a Boomer DOES get his vomit attack
off, the Hunters on your team can try to get an extra claw swipe or two
off before their vision returns to normal. If you DO plan on attacking
this way as a Hunter, make sure it's immediately after the Boomer's
attack. If the survivors decide to make a run for it, you'll have a
spawn time in front of you...

*SMOKER TIP*
Drag them off the awning. They won't grab hold of the edge...they'll
drop all the way down and most likely take a hefty chunk (25+) of fall
damage. If the survivor team decided to rush past the event, not only
do you drag one of them down, but then the horde will likely swarm in
to assist you with your pull. Incapacitations here are perfect targets
for Hunters to land big pounces on any survivor coming to the rescue.

*HUNTER TIP*
As the survivors either ride the lift up or climb the ladder to the
awning, you can land HUGE pounces from the roof of that building. There
are two raised sections of that roof that can provide a little more
distance - and therefore damage - for your pounce.

Across the awning, the survivors will enter a storage room with a hole
in the floor. If you're a Smoker, try and drag that last survivor back
as they fall through the hole to the level below. It can really dish
out some damage or even score a kill.

If the survivor team decided to rush past the event, odds are they'll
camp out in one of the closets in that building after dropping down
through the hole in the floor. There isn't really a whole lot you can
do here to attack them. Hunters can *try* to get a quick swipe off, but
I find it a waste. However, if a survivor ventures too close to the
windows, a Smoker can pull them down to the level below. Nearby for the
survivors is a switch to the metal dock door on the level below, so it
may not be a huge inconvenience...but it's still an inconvenience.
Otherwise...sometimes you'll get lucky with a survivor team who all
rush down to help, forcing them to remake the trip across the awning.
That's always fun!

There is a first aid box that will contain pills or med packs, and
there is an ammo pile in that room just past the hole in the floor. The
first aid box I never understood as there are several rooms down that
long hallway that more often than not contain plenty more health packs,
pills, molotovs, and pipe bombs. The survivors can jump down into the
large storage room from the windows, or backtrack and take the stairs
down. Either way, survivor separation in this area can be very hurtful
to their team.

*TANK TIP*
Sometimes a Tank will spawn here. There is a forklift and pallet jack
you can use to bash into the survivors. Pallet jacks are actually
pretty light when compared to the force of a Tank's punch, and they'll
go flying every which way, rather than in a straight line. Stick with
the forklift. Odds are one (if not all four) of the survivors will have
a molotov at this point. Try to get as much damage done as you can, and
remember, if you need to wait for your teammates to spawn before
starting your attack, then wait. Doesn't make much sense to go solo and
get torn down immediately. Boomers summoning hordes here can be fatal
for the survivor team if a Tank is present.

After the large storage room, the survivors enter a narrow outdoor area
before entering the sewers.

*HUNTER TIP*
It won't land a huge amount of damage on the survivors, but I bet it
will make them jump! You can actually perch on the edge of the roof
adjacent from the roof with the awning from earlier in the map. This
perch is directly across from where the survivors enter the narrow
outdoor section, and I have *never* been shot at from suspecting
survivors in this location. Don't go for huge pounces here as one of
those infamous red "out of bounds" barriers will appear in midair and
halt your pounce. You can, however, leap downwards from that ledge at
about a 15 degree angle to land a 12-14 damage pounce and probably
scare the crap out of one of them!

The survivors will enter a sheltered narrow hallway and then descend a
staircase into the sewer section of the map. There are two entrances to
the sewers. The shorter path is directly across from the stairwell.
There aren't usually any items near that entrance for the survivors to
collect, so many teams opt to enter the alcove to the right of the
stairwell's exit. There are 9 times out of 10 goodies here for the
survivors to stock up on.

*SMOKER TIP*
There is plenty of cover here for you to take advantage of. And </pre><pre id="faqspan-3">
regardless of which sewer entrance the survivors decide to delve into,
your goal is the same. Snag the last one to try jumping down. The
survivors canNOT shoot through this floor, and it is essentially an
instant kill for you! To combat this, many survivor teams will toss a
molotov at the entrance of the alcove from the right entrance, and in
the middle of the septic tanks if taking the straight entrance. Either
way, your tongue is long enough to go over the fire and land a hit,
dragging one of them back. Good luck!

Down in the sewers, the survivors will generally stick to the wider
open paths. Usually there is an ammo cache down here, and sometimes
goodies will be in supply in a few of the rooms off to the side. Thing
is...most survivor teams just try to get through the sewers as fast as
possible since it's close to the end of the map.

*TANK TIP*
If a Tank spawns in the sewers, molotovs are of no concern to you! This
is one of only a few locations in the entire game where you can put out
the fire should you be lit up. Simply run through the sewer water.
That's it.

*HUNTER TIP*
The exit from the sewers is one of the most infamous Hunter pounce
locations in the entire game. And rightfully so. A successful pounce as
the survivor is still climbing the ladder will for him/her and any
other survivor all the way back down the ladder, dishing out some fall
damage as well. If you manage to pounce a single survivor all the way
down, the fall damage alone is enough to incapacitate him/her.
There are several locations from which you can safely land a pounce.
1) From the car near the building behind the ladder at the sewer's
exit, you can pounce onto the metal staircase, then from there, pounce
on top of the building. This can net you a 20 damage pounce on contact,
plus fall damage, plus shredding damage. If you can pull this off, it's
lethal.
2) From on top of the bus stop shelter. Not nearly as damaging, but the
pounce is more accurate.
3) From the ground. Go for the quick one.

Be wary though, as many survivor teams will launch a molotov up the
chute to try and foil the infected plan by hitting any infected player
caught napping. A successful ambush here is critical to your success as
the end of the map is mere seconds away.

*SMOKER TIP*
There are two popular locations to help ambush the survivors as they
emerge from the sewers.
1) From behind the bus stop. The common strategy is for the Smoker to
drag the first one, then the Hunters can fight over who pounces first,
and so on.
2) From BELOW. Yes... Save your spawn until after the survivors start
climbing the ladder, then look straight up, snag one, and drag em'
down!

*TANK TIP*
If the AI Director is feeling particularly nasty, it may spawn a Tank
in this location. If that's the case, there are plenty of cars and
dumpsters to smack the survivors' way and cause some instant
incapacitations. If a Tank does spawn, communicate with your teammates
to ambush them at the entrance of the hospital. Because this spawn
location is so close to the end of the level, the survivors may try to
make a run for it. Make sure your teammates are ready if the survivors
try that.

The ambulance at the entrance of the hospital often contains a health
pack, and there are several rooms just before the safe room that can
contain goodies. If a stupid survivor who goes venturing into one of
these rooms, make him/her pay for not just finishing the level as soon
as possible. The Sewers map of No Mercy is a long one...no need to make
it any longer than it has to be. If the survivors make it to the
entrance of the hospital, odds are they'll make it to the safe room.
Just try to dish out a little more damage here to lower their score if
you can.


**************************************************************
-------The Hospital------- [L4DMERCYd]
**************************************************************

The fourth map in No Mercy plays much differently than the previous
three. There is a lot more cover for Boomers throughout the majority of
the level, and while the survivors can shoot through the walls in many
areas of the map, I found that because this level is rather lengthy,
most survivor teams tend to - for lack of a better word - rush through
the first 70% of the map.

There are NO locations on this map for big Hunter pounces. However,
with all of the side rooms, and many hallways, getting separated on
this map can mean only being on the other side of a wall, and can
result in some extra damage.

Immediately out of the chute, the survivors will more than likely rush
to the right after leaving the safe room. There is a T junction on this
level. Boomers can set up there to try and slow the team down. It's
pretty common for the Smoker to set up from behind the curtains left of
the safe room's exit to drag one back, but the damage won't be great,
and you have no hiding spot to run to. Best to save the Smoker until
after they reach the mezzanine.

*HUNTER TIP*
You can't get much done at the beginning of the map. However, you can
help to slow the survivors down by indirectly attacking them. After the
first section of the spiral staircase, there is an open area. The
mezzanine here has railings that can be broken with 9 claw swipes. Try
to get at least one of them destroyed - preferably the railing closest
to the next section of the spiral staircase. The large open area has
two entrances the survivors can come in from. Directly underneath the
railings you can attack, and from the middle of the room, through the
kitchen entrance. If they come through the former, you can land a 10 to
13 damage pounce here if you've got good aim.

Sometimes, a Boomer's vomit at the very beginning will cause a horde to
take care of those railings for you. It wouldn't be a bad idea to
double check. This mezzanine section is an ideal place to keep the
survivors in one spot for a prolonged period of time. The longer they
stay in the field of play, the more damage they'll take.

*HUNTER TIP*
Just before the staircase leading to the mezzanine, there is a skylight
dripping water. You can actually pounce straight up through the
skylight and land on an invisible ceiling. There are a couple of white
vents you can pounce onto. Stand on the front left corner, and aim your
pounce at the widest section between the bars. The survivors MUST pass
by here to proceed, and I've never been attacked by a suspecting human
player. Bots may react differently. The pounce probably won't exceed 6
to 7 damage, but it's nice when you can pull it off as it forces
everyone to jump and react to something immediately and cause some
chaos.

The survivors must cross the mezzanine, and this is where a well co-
ordinated infected attack can spell disaster for them. Keeping them in
this area for 45 seconds is great. A minute is spectacular. Two minutes
basically guarantees at least one death amongst them, and a loss of
several, if not all of their med packs.

*SMOKER TIP*
Pull a straggling survivor (or ANY survivor) down from that level. You
will more than likely be hunted down and killed, so if only your tongue
gets broken, go in with claw swipes for a little extra damage. Get
something else out of it before you meet your maker. Pulling one down
will force them to run back to the stairs and remake the trip. It
doesn't cause any fall damage, but it's a big inconvenience when
combined with a Boomer's vomit.

*BOOMER TIP*
Puke on the survivor who just got pulled down. It will keep him/her
there for a prolonged period of time...maybe even long enough for a
Smoker to respawn in which you can do it all again. Because the vomit
attack takes 30 seconds to recharge, you're better off puking, then
going kamikaze. Odds are you'll be met with a 20 second respawn time,
so it's more than likely going to be beneficial to your team to
sacrifice yourself (and cover more survivors if possible) and take
what's probably going to be a shorter wait. Keep the pressure on them
in this area!

*HUNTER TIP*
Do whatever you can to keep the team distracted here. Pounce any
straggler, pounce anyone who didn't drop down to help escort the
ensnared survivor. Keep them in this area at all costs. You can grind
them down little by little, and if infected attacks are spaced out
evenly enough, you can probably make the survivor team remake that trip
across the mezzanine three or four times!

*TANK TIP*
Sometimes you'll get a Tank at the beginning of this map. It's nice,
but because of the narrow hallways and the availability of tier 2
weapons right from the get-go, odds are everyone on the team will grab
an Auto-Shotgun. This is your worst enemy. I cannot stress this enough.
If you need to wait for your infected teammates to respawn, let them.
Auto-Shotties cut through Tanks like a hot knife through butter. The
narrow hallways are ideal for catching up to the survivors should a
Boomer vomit on a couple of them.

Like I said, keeping the survivors in this area for 45 seconds is
great. Anything over a minute is just gravy. The survivors will then
need to go up another section of the spiral staircase. They'll be
turning right out of the stairwell, so Smokers head left and hide
behind the wall to drag the last one to leave if you can.

There are a lot of rooms off to the side in this section of the map.
Boomers can take advantage of the many angles from which to attack
from, and keep in mind that a lot of the walls in this section can be
broken down. These breakable walls provide 2 benefits to your team.
1) They "open the floodgates" for infected to rush at the survivors
during the upcoming crescendo event, and 2) Allows you different angles
to attack the survivors from immediately.

The survivors must head down a long and narrow hallway with a few side
rooms on either side. I wouldn't recommend spawning in any of these
rooms as they have narrow entrances, and can be difficult to sprint out
of as any infected character.

The crescendo event starts once the survivors call the elevator. It
starts on the 28th floor, and stops at the 4th floor. The common (and
called to be patched many a time) survivor strategy here is for all of
them to huddle in the corner behind a hospital bed directly across from
the elevator entrance. The reason why this has been called to be
patched so often (to no avail as of yet) is because the common infected
must first climb over the bed, THEN attack the survivors. This means
YOU must climb over that bed and attack the survivors. There isn't
really much you can do at this point, and your team will want to save
it's Smoker here. If you're a Hunter, you can jump over the bed and
claw them while airborne. Usually you'll hit more than one survivor
with the attack. While it isn't much, it's usually more damage than
you'll get out of landing a pounce at this section of the map,
unfortunately.

*SMOKER TIP*
It's incredibly difficult to pull off, but very satisfying when you do.
And might I add that it's humiliating for the survivor team...AND it
results in an instant kill! From directly in front of the elevator, try
pulling a survivor out of it as the doors close. Sometimes there are
common infected that will block you from pulling the survivor back to
you...actually leaving them in the elevator. Sometimes you have no good
angle to get a good pull on one of them. Sometimes you'll pull too
early and die before they even close the doors. And sometimes you'll be
a split second too late. The window of opportunity here is VERY small,
but it CAN be done... Good luck!

The elevator ride takes a while. If you are stuck on the 4th floor, the
doors will open, and you have a choice. Either run back towards the
safe room at the beginning of the map until you see the "Too far away
from the survivors" message, then press "E" (by default) to respawn
closer. Or, make the long climb. It's probably faster to climb it as a
Hunter, as you can crouch on the pole, and pounce straight up. It's
actually a pretty efficient way to get up there in a hurry.

Once the elevator opens, the survivors must make their way around the
ledges of the building in order to make it to the safe room.

*TANK TIP*
There are 2 locations where Tanks can spawn when the survivors get off
on the 28th floor. One is immediately after the elevator doors open. If
that's the case, the common survivor strategy is to head through the
vents on either side of the elevator and make you come to them. This is
kind of annoying as it almost forces you to get popped full of holes
trying to reach them. However, there is a generator that the Tank can
smash. Obviously if it hits a survivor, it's an instant incap. However,
if you can angle it towards one of the vents, you can block the
survivor's path. I have never noticed the generator disappearing over
time...probably because there are two exits from behind the elevator.
What this does is force them to go one way. If your infected teammates
scan spawn in the room with them, a Boomer's vomit here is extremely
helpful, as you can use the ensuing horde's distraction to corner and
incap one or more of the survivors.

*TANK TIP*
The other location a Tank can spawn is as the survivors are walking
around the ledges of the building just after they leave the elevator.
Sometimes they'll run back to the vents. If that's the case, try the
above strategy. But sometimes, they'll try to fight you head on. Big
mistake! There is a forklift you can smash into them which will result
in instant incaps should it connect. AND...here is your first
opportunity for a Home Run. A Boomer's vomit here can slow the
survivors down long enough for you to position yourself and punch a
survivor...right off the building. Instant kill.

There are some locations where the path the survivors must follow is
rather narrow. Just past the forklift, there is a stack of boxes with a
closet just beyond it. It's a perfect place for a Boomer to ambush the
team. The path here is very narrow, and any trigger happy survivor
standing too close to the edge can actually instant incap him/herself
by blowing you up and staggering over the ledge!

*BOOMER TIP*
Slowing the survivors down here is extremely valuable to your team. The
path leading to the safe room is full of narrow hallways that can get
flooded with normal infected, and allow the Hunters and Smokers on your
team the chance they need to get some extra damage in.

*SMOKER TIP*
As the survivors pass the alcove by the stack of boxes, an opportunity
presents itself for you to drag a survivor to an instant
incapacitation. Spawn behind one of the pillars and as the survivors
make a run for it, try dragging one back over the ledge. They'll be
hanging on for dear life, but it slows the team down for an extra 5
seconds while one of them is helpless. A co-ordinated attack here with
3 Hunters can be devastating for them!

The narrow passageways the survivors must follow allow for the infected
to get a bit more damage in than on the previous maps, however, if the
survivors make it this far and they're not in horrible shape, there
isn't much you can do.

*HUNTER TIP*
Spawn just outside of the safe room and run in. There are some boxes
you can hide behind. Another Hunter can hide in there with you. There
have been numerous times where only two survivors were left and made it
to their destination when all of a sudden, two Hunters pounced on them
and made their kills, denying them extra points...all in the safe room
with the door closed.

**************************************************************
-------Rooftop Finale------- [L4DMERCYe]
**************************************************************

The finale to No Mercy plays much differently than the finales in the
other campaigns. It's a rather short map, and the "make or break" point
is a favorite amongst infected teams.

There are two ways you can try to stop the survivors cold. The "make or
break" point is the tall ladder that gives the survivors access to the
rooftop.

The first way is to have the Boomer on your team get the survivors
right away and allow the rest of the team to sprint up to the rooftop,
where they will all wait in position. When the Boomer dies, he/she will
most likely respawn as a 3rd Hunter. This is where the ambush comes in.
Everyone now sets up on top of the room. Be careful as many survivor
teams are well aware of an ambush here. Because of this, the Smoker on
your team should not spawn until after he/she sees the survivors
climbing up the ladder. The best (and most common) place for the Smoker
to spawn is by the satellite dish. This allows him to drag a survivor
down a level and separate him/her while potentially causing a hefty
chunk of falling damage. The Smoker should ALWAYS attack first to force
the other survivors up the ladder to try and assist the ensnared
teammate. Then, the Hunters try to clean things up. You can pounce a
survivor all the way back down the ladder and potentially cause some
falling damage. This will also force any survivor also on the ladder
back down, thus giving the Smoker more time to dish out some damage.
With 3 Hunters, you can quite possibly stop things here with a well co-
ordinated attack. Communicate with your teammates to orchestrate this,
and if all goes well, the survivor team didn't even get a chance to
summon their rescue helicopter!

The second way is to have EVERYONE rush up to the rooftop...Boomer and
all. The goal here is to try and grind the survivors down until they
have nothing left. Done perfectly, this strategy works wonders and
forces the survivors to either risk taking excessive damage, or waste
valuable throwing weapons. The Boomer should puke on the first survivor
seen peeking through the hole. Some survivors will try to just rush
through it. This leaves him/her open to being pulled off the roof by a
Smoker...and THEN beaten by the ensuing horde. The Hunters can then do
their dirty work. However, if the survivor decides to return down the
ladder, the horde will jump down the hole. The Boomer can then sit on
the ladder near the top. Since survivors cannot move through any
infected character, they'll be stuck. This leaves the Smoker on your
team an opportunity. If the Smoker has not spawned yet, he/she can
press "E" (by default) to get closer to the survivors. There is a gap
in the fence near the area the survivors are by that can be used to
drag one of them into an instant incap. So now there's a horde coming,
and potentially an incap complication. While one of the survivors is
helping the incapped teammate up, the Hunters can move in and dish out
some serious damage. The Boomer is still sitting at the top of the
ladder, and if the survivors shoot him, he'll explode and rain puke
down on anyone directly below...calling ANOTHER horde.

Using that second strategy can really grind the survivors down little
by little. They may toss their pipe bombs, they may use another
molotov, and they may be forced to use a health pack or two. Either
way, this choke point at the rooftop's entrance is a favorite ambush
spot amongst infected teams, and for good reason.

*SMOKER TIP*
*HUNTER TIP*
Co-ordination is very important between teammates, as the window of
opportunity depending on the survivor team can be either very
small...or extremely small. However, it can spell an instant kill for
the infected team. After reaching the rooftop, the Smoker on the team
can head to the left immediately after emerging on the roof and stand
on the two air conditioning units. A Hunter can spawn on the opposite
side of the roof - doesn't really matter where. The Smoker needs to
pull a survivor towards him, and the Hunter needs to pounce on that
same survivor when he/she reaches the Smoker. Depending on the angle at
which the Hunter pounces, you can push a survivor onto the short raised
corner section of the roof for some serious falling damage...or...you
can actually pounce them all the way off the building for an instant
kill!

Should the survivors make it to the top of the roof, they must summon
the rescue helicopter and start the finale event. Finale events play
differently from the other sections of the map. You will not be able to
choose your spawn points once the event starts. You will appear at a
random spawn location as a random special infected. The many different
levels of the hospital's roof can offer some protection as you try and
make your way to the survivors, but some of the spawn locations are a
lost cause...putting you out in the open on the other side of the
map...as a Boomer. Just try to bob and weave your way close to the
survivors to get an attack off. Boomers, as always are very valuable
here as they can summon additional hordes and hamper the event's
progress.

The event follows a pattern.
1) Horde
2) Tank
3) Horde
4) Tank
5) Last ditch effort Horde and Tank

A Boomer's vomit during the Tank sections increases your chances of
success ten-fold. Survivors surrounded by a mob are easy targets, and
on the rooftop of Mercy Hospital, easy targets equal easy Home Runs for
Tanks.

*TANK TIP*
The higher the level the survivors are on, the better if you can land a
punch on them. Sometimes you can send them flying towards the edge,
resulting in an instant incap. Sometimes you can hit a Home Run and
send them off the building. If you are playing as the Tank, and the
survivors are on the platform with the minigun, try to force them to
run across the pipe on the right side of the mounted gun (when facing
the helipad). This can open up an opportunity for the Smoker on your
team.

*SMOKER TIP*
Below the pipe to the right of the mounted machine gun (facing the
helipad), you can drag a survivor all the way down resulting in an
almost game-changing amount of falling damage. If the Tank on your team
can force a player to run across the pipe, try not to miss the
opportunity to yank one of them down. If you incap the survivor (which
from a fall that high, it's not unlikely) the others make themselves
sitting ducks for Boomer vomit once they go to rescue him/her. A horde
down there can be disastrous for the survivors.

Many survivor teams make their stand on the finale event by the mounted
machine gun. There is an ammo pile there, med packs, and tier 2
weapons. Big pounces from Hunters are difficult to pull off as it's a
wide open area, and since the survivors have nowhere to go for the time
being, they all go into "defense mode." There are two decent locations
to land a big pounce, but know that they are both risky as you must
present yourself in front of them for at least a little while, and you
can be easily spotted.

*HUNTER TIP*
To the right of the mounted machine gun (facing the helipad), there is
a building connected by pipes. You can pounce up to the top of that
building, and arch a leap over towards the rooftop the survivors are
on. If one of the survivors is using the mounted machine gun, it's an
easy target to hit. You can manage a 15 damage pounce here. The other
location is actually from atop the satellite dish. This location is
more difficult, as you'll be almost directly in front of the survivors,
but pounces around 18 to 20 damage can be achieved from there.

After two hordes, and two Tanks, the helicopter will arrive. This is
your last chance to incap or kill a survivor. Smokers can hide to the
left of the helipad and drag one down below. A Boomer here can be very
valuable, and Hunters have to do what they do best. The Tank your team
will receive here is hardly of any use, but if that Smoker is able to
drag a survivor back from the helipad, know that until he/she is
incapped, the match will not end. This can allow the Tank a chance to
get up in the other survivors' faces and lower their health score, or
incap them outright. You canNOT punch a survivor out the other side of
the helicopter...sorry!

Show the survivors No Mercy.


**************************************************************
-------Crash Course Overview----- [L4DCOURSE]
**************************************************************

Crash Course is the latest Download Content campaign from Valve. It is
a two chapter bridge campaign that links the end of the No Mercy
campaign and the beginning of the Death Toll campaign apparently, even
though Death Toll's beginning shows nothing of the escape vehicle used
in Crash Course's finale. Anyway...

Crash Course, as I said earlier, is a two chapter campaign with quite
possibly the most brutal finale map ever as it consists of a rather
lengthy road to the actual event (when compared to the other
campaigns). This allows for the infected to rack up some serious damage
or even outright stop the survivors before they even reach the finale
event! It happens.

Crash Course takes place at night, much like Death Toll, and as such,
creates a little cover for Hunters waiting to pounce as their
silhouettes aren't quite as noticeable - though skilled survivor
players will still be able to see you rather easily. And staying on the
Hunter topic, a lot of the rooftops in Crash Course are inaccessible,
making some areas rather difficult to pounce for high damage.

The Crash Course campaign also features multiple paths for the
survivors to take. This can make ambushing survivors more difficult as
laying in wait to attack in one area may be countered with the
survivors - unbeknownst to them - thwarting your plan by taking a
different route. So just as a rule of thumb, don't spawn as the
infected until you either:

a) Know where the survivors will be going and can set up an ambush.
-or-
b) Are ready to attack.

You'll also (though this is a given in any scenario) want to make sure
your infected teammates are keen to what you'll be up to. The different
paths may provide different angles from which your team can administer
an attack, so try your best to co-ordinate your scheme beforehand to
maximize your damage output.

Because Crash Course has these differing paths, it's quite difficult to
list the various Tips I put throughout the individual map strategies
without turning the Crash Course campaign guide into a book the size of
"Atlas Shrugged", so the Tips will be included in the areas for which
the survivors MUST pass to advance in the level.

Another thing to mention about Crash Course is that alarmed cars spawn
in random areas. This can inspire makeshift ambushes.


**************************************************************
-------The Alleys------- [L4DCOURSEa]
**************************************************************

The survivors start out in a wide open area with the wreckage of the
News Chopper 5 in front of them. Francis may be talking about how he
loves helicopters...but promptly gets back in character to say he hates
them.

The wide area presents a problem for Hunters to land high damage
pounces, in spite of the building off to the survivors' right that can
be climbed up on. It also presents a rather large problem for Boomers
to get a meaningful attack off and create the chaos the other infected
teammates require to orchestrate a damaging ambush. There is a narrow
alley the survivors have to go through to advance off to their left
after traversing the parking lot.

*Hunter Tip*
There is a zig-zag outdoor staircase in the alleyway that you can use
to score a high damage pounce on when the survivors get close to the
alley.

*Boomer Tip*
The alley has several garages that you can spawn in to ambush the
survivors.

The chapters of Crash Course are rather lengthy, so expect the
survivors to find plenty of Pain Pills, throwing weapons, and Medkits
throughout the levels. However, in spite of the number of goodies the
survivors will pick up, this allows your infected team more time to
dish out damage. The alleyway the survivors must travel down is usually
littered with TONS of item pick-ups, so you may have a little more time
to spawn after dying as a lot of survivor teams tend to check these
garages before moving on.

*Tank Tip*
The survivors must enter a warehouse with a Forklift positioned right
at the garage door. If the survivors don't immediately backtrack, you
can use this to instantly incap them.

*Smoker Tip*
Crash Course is dotted with lots of gas cans. More often than you'd
expect, stray bullets ignite these, so you can use them to your
advantage by pulling survivors into the fire for more damage.

Outside of the warehouse, the survivors will travel down a narrow
corridor with a fence on one side and a building on the other. The
building has a zig-zag staircase for Hunters to jump up on to try and
land bigger pounces.

The survivors will reach a failed barricade with a semi-truck turned on
end and just past that is a cliff with an oil tanker tipped over the
ledge. The survivors must jump down to the road below and follow that
around the hill to their right. They'll be passing under a bridge.

*Smoker Tip*
After the survivors drop down, try dragging the last survivor back. It
takes a little while for the survivors to climb back up resulting in
you doing quite a bit of damage, and setting up an ambush from a Boomer
or Hunter.

*Hunter Tip*
From atop the bridge the survivors need to pass under, you have a great
vantage point to pounce on the survivors for big damage.

Up the hill, the survivors need to fire a Howitzer in order to clear a
path across the bridge. This crescendo event can be rather frustrating
for the infected team, as a lot of survivor teams tend to enter the
nearby building and hold out there until the event has passed. This
wouldn't be such a big deal, but the survivors will corner camp atop a
shelving unit that you must first run up to, then try scratching while
jumping as a Hunter. It also offers very little chance for a good
Smoker pull or a meaningful vomit attack from Boomers.

*Boomer Tip*
Save your spawn until after the event has ended if the survivors try
holding the fort inside the building. You simply won't get a good
chance at damage.

*Smoker Tip*
See the Boomer Tip above.

After the event, the survivors will cross the bridge that is scattered
with cars and trucks which provide ample cover to spawn behind as a
Hunter for quick attacks. The many beams atop the bridge can interfere
with a big damage pounce, so work for "jack-in-the-box" style surprise
attacks in conjunction with your infected teammates. If the Boomer
saved his spawn until the survivors try crossing the bridge, you can
get a surprising amount of damage dealt to the survivors in this area.
It isn't very wide open and since it's littered with cars...

*Tank Tip*
A Tank here can be devastating to the survivor team. Combined with a
Boomer's vomit, the amount of cars you have to hit at your disposal is
almost unfair!

Past the bridge, the survivors will head down a steep hill and into a
warehouse containing the safe room. Do your best to damage the
survivors here because it's your last chance before they end the level!

**************************************************************
-------The Truck Depot Finale-------- [L4DCOURSEb]
**************************************************************

The survivors start out in a warehouse with a door leading outside
straight ahead. There is an awning Hunters can pounce from, but be
warned that a lot of survivor teams will stand in the doorway and pick
off as many zombies as they can before venturing forth. The angle at
which you need to land a successful pounce while they're in the doorway
is rather awkward, so it may not be worth it right out of the chute.

The survivors will go through a fairly wide open area, but will pass
through a dock door on the ground to get around a bus crashed in the
middle of an alleyway.

*Hunter Tip*
There are several air conditioning units that you can jump up on and
try to land 10-18 damage pounces from. Be careful, however, as it is a
pretty wide open area, and a missed pounce here will probably end up in
you waiting to respawn!

The survivors will pass under a large bridge, but unfortunately, there
aren't many, if any meaningful areas for a Hunter to make a big pounce
from in this area. However, Boomers can take advantage of the tighter
area.

*Boomer Tip*
There are several crashed vehicles for you to spawn behind to get an
attack off in the area underneath the large bridge. The survivors may
be able to bob and weave their ways into the nearby office building,
but a quick Boom combined with a Smoker here can bring a survivor out
into a more favorable location for a Hunter to make a damaging pounce
from.

The survivors will pass an area with several shipping containers. A
Boomer here isn't as valuable as you may think. Survivors who get
vomited on will likely hide in one of the containers until the effect
wears off and his/her teammates will protect resulting in little to no
damage being dealt through the chaos.

Past the areas with the containers, the survivors will climb atop a
semi truck to get over a wall and head to the truckyard where the
finale takes place. One of the survivors must start the
generator...which makes his/her a sitting duck for a precious 5
seconds.

*Hunter Tip*
You can get to the top of the tall building overlooking the generator.
I don't think I need to tell you what you need to do to dish out some
major damage here while a survivor is immobilized for the time being!
This is a great area to get the "Jumpin' Jack Smash" achievement.

After the event is started, the common survivor strategy is to hide out
in the room below the mounted machine gun. There are two entrances
initially, but zombies will make short work of the walls, creating two
more holes for Smokers to try and pull survivors out of.

*Smoker Tip*
Do whatever you can to pull a survivor out into the open. It provides a
great opportunity for Boomers to vomit on survivors, and bring one of
them into a wider area for Hunters to try and pick off would-be
rescuers!

Like the finale events in the other four campaigns, Crash Course's
finale follows a pattern.

1) Horde
2) Tank
3) Horde
4) Tank
5) Last ditch effort Horde + Tank

However, UNLIKE the other finale events, Crash Course's finale has a
slight disruption. The generator goes out and needs to be restarted!

*Hunter Tip*
Did you miss the first time a survivor tried starting the generator?
This is your chance for redemption!

When the escape vehicle finally touches ground, the survivors will make
a mad dash towards it. This is your ONLY opportunity to get the "Truck
Stop" achievement. So go out there and make me proud! A Smoker in this
situation is absolutely necessary, and Hunters need to make sure they
pounce on any survivor going to the rescue. However, from what I've
noticed in my plays through Crash Course's finale, most survivor teams
will simply abandon their downed teammates to put more points on the
board.

Either way, do your best to Crash the survivors' Course of action!


**************************************************************
-------Death Toll Overview------- [L4DTOLL]
**************************************************************

Death Toll is one of the less-often played VS maps from my experiences
online, but it's fun nonetheless if you can get things into a rhythm as
the infected. There are choke points on every map that force the
survivors to cram themselves in to progress. There are also many
locations for big damage pounces due to cliffsides, houses, bridges,
towers, and tall trees.

Death Toll, unlike No Mercy offers some thick foliage on most of the
maps that can offset a Smoker's visual cue. The foliage provides visual
cover only, however. It's not really great at stopping bullets coming
your way! Boomers can try to take advantage of the foliage cover, but
most survivor teams will try to stay away from the thick brush as a
precaution. That being said, you can fool them through reverse
psychology and attack from a non-usual spot. This applies to MANY
locations in Death Toll. The thick foliage may prohibit the survivors
from actually seeing you, but the game doesn't seem to think so. You
*will* have to find additional cover to spawn since technically you are
"out in the open."

Death Toll has been altered in a few locations for balance in VS mode.
The Drains map has been altered in the bridge crescendo event room. It
now offers several more angles from which you can attack the survivors.
The Boathouse Finale map now offers a Hunting Rifle at the end. The
weapons and health packs are now positioned outside on the deck instead
of on the first floor of the house. The house has been dramatically
altered as well. There are no more closets for the survivors to huddle
in behind unbreakable walls. In VS mode, the house turns into swiss
cheese. There's even a section of the roof that will give way.

Like No Mercy, Death Toll is a very dark campaign. It takes place just
before nightfall, and most of the maps take place almost entirely
outdoors. Because of this, big damage pounces from Hunters are rather
common on this map. From a distance, Hunters are difficult to spot
against the sky, and in front of other objects, the silhouette from
whatever you're in front of can make it darn near impossible to point
you out. Be careful if computer controlled bots are on the survivor
team, though, as they can still "see" you. As stated earlier, the thick
foliage on several of the maps can offer adequate cover once you've
spawned. Bots can also see through the thick branches, so take that
into consideration when planning your attack.

Death Toll has three major Crescendo Events aside from the finale. Two
of which the survivors must stop and wait for. The other can more or
less be rushed past if the survivors decide to do so. One of these
crescendo events is at the very end of a map, and has a rather infamous
hiding location that has been called to be patched to no avail as of
yet.


**************************************************************
-------The Turnpike------- [L4DTOLLa]
**************************************************************

In spite of the actual length of this chapter, it actually flows rather
quickly because the first 65-70% of the map is pretty much a straight
line! It's generally the best idea to ambush the survivors at the first
obvious choke point...the ladders.

This map actually has two major choke points that can cause some
hesitation amongst survivor teams. The first choke point is on the
ladders just past the broken bridge. There are two ways the survivors
can go here. The right side is the most common route, even though the
left side is widely considered to be not only shorter...but safer! Many
survivor teams, as a way of avoiding the thick foliage on the left side
of the turnpike stay in the middle of the road, or hug the right side
by the cliffs. This can make it frustrating for spawned Boomers looking
to get their vomit attack off and as such, you may be better off
waiting until the chock point. However, if you think you can vomit on
at least one of the survivors, from the left side of the turnpike, go
right ahead!

*SMOKER TIP*
One thing I've noted a lot of survivor teams do...for whatever reason I
can't comprehend, is to stand at the edge of the broken bridge before
venturning down and heading to the ladders. A Smoker from the other
side of the broken bridge can pull a survivor down for some major
falling damage. This is one of those really rare situations where a
Smoker should spawn in front of the team.

*SMOKER TIP*
If the survivors are heading up the right side ladders there are two
ways to really put the hurt on them.
1) Spawn by the semi truck and jump on the ledge next to the survivors.
Dragging one back here in just the right spot will drag them down and
hang them about 20 feet above the ground. So now, when you die or your
tongue is broken, that survivor is going to take a pretty decent chunk
of falling damage. Even if you don't perform that drag perfectly, you
still force that survivor to re-climb the ladder.
2) Spawn below the survivors and try dragging one of them all the way
down. This is a much more direct amount of falling damage, but it
usually takes less time for the survivors to recover, and it can pull a
victim too far away from the other survivors and lessen the chances for
a big pounce from the Hunters on your team.
If the survivors are heading up the left side ladder, the best location
I've seen so far to achieve a falling damage pull is from directly
behind the survivors. There is also a small gap on that ledge where the
railing has broken away, but since it's 99% of the time such a small
window of opportunity, you're better off not even trying.

*BOOMER TIP*
Regardless of which side the survivors climb up, the jackknifed semi
truck offers enough cover to spawn and slow the survivors down. This
location really doesn't allow the survivor team much reaction time.

*HUNTER TIP*
You can get on top of the cliff hugging the right side of the street.
It may take a few pounces to finally get up there, but it offers a
tremendous vantage point. If the survivors decide to climb up the right
side ladders...25 damage pounces are very...VERY common here. Two
Hunters leaping from this perch can be devastating to the survivor
team, especially if a Smoker was able to drag one off the ledge as
well.

After the ladders choke point, the survivor team must enter a tunnel
littered with cars. This long, straight stretch of the map is littered
with cover for Boomers and Smokers to hide behind, and there are
several alcoves along the main path that you can use to spawn in and
deliver quick attacks from.

*TANK TIP*
Occasionally, a Tank will spawn on this map. The absolute perfect place
for one is in the middle of the tunnel. The survivors may have picked
up a gas can or molotov by this point, so be sure to check what they're
carrying or at least ask your teammates before jumping into the fray.
Most of the cars in this tunnel CAN be moved. And remember, if a car
slams into a survivor, it's an instant incapacitation. If the survivors
run back towards the entrance of the tunnel, a common place for them to
camp out is on top of the jackknifed semi truck. Start throwing rocks
at them! They only have tier 1 weapons, and also make themselves very
vulnerable to any Hunter, Smoker, or Boomer on your team

Inside that tunnel, there are several alcoves that can contain a 2nd
pistol, pipe bombs, molotovs, and pain pills. One such alcove is a
common place for a med pack to appear for the survivors. I guess the
game developers decided that because such a treacherous choke point was
just passed, they would reward the survivor team... The common med pack
closet is on the left side of the wall, behind a broken section of it
and down a narrow hallway. There's usually a gas can there too.

*BOOMER TIP*
The bars covering the small hole in the concrete in that wall do not
stop your vomit from reaching the survivors. Go ahead and take your
shot if you get the opportunity. Odds are the survivor team will just
huddle back in that corner or closet. This can open up a brief
opportunity to "grind" the survivors down slightly with well organized
and spaced out attacks. Have the Hunters and Smoker on your team attack
in 5 second intervals. If they can keep the pressure up after your
vomit attack wears off the survivors, you will only have to wait 2 to 3
more seconds until you're recharged. Vomit on them again, and it will
give your teammates a great chance to respawn and keep the pressure on
them!

In the tunnel, there are 2 locations where infected players can climb
up to a higher level. These are the obvious ambush spots. Survivors do
what they can to rush past them as quickly as possible, and if they
hear a Boomer or Smoker nearby, more often than not they'll send a
molotov up there. Best to avoid these locations. They're too obvious,
they're not really practical for attacking from, and they don't really
offer much cover. Besides, there are plenty of cars and walls to spawn
from behind and attack from.

After the survivors reach the dead end of the tunnel, they'll be
turning left and heading down a series of staircases. They'll enter a
room with a mezzanine (which they'll be starting out on) and a lower
level that can contain all sorts of goodies. Believe it or not, most
survivor teams from what I've seen tend to try and make it out of there
quickly without checking all of the individual rooms. Maybe because
they're now relatively close to the safe room...? Either way, on the
lower level of that room, it's common for the survivors to find another
med pack, pills, ammo, molotovs, pipe bombs, and gas cans or propane
tanks. It really is amazing to me seeing a lot of people skipping these
item picks ups!

Coming out of that room, the survivors will head up a small
staircase...and this is where they can hesitate to leave. Welcome to
the 2nd choke point on the map. People expect big pounces from Hunters
as they leave that stairwell.

*BOOMER TIP*
This is another one of those rare occasions where it's actually wise to
spawn behind the survivors and make them pay for not heading out into
the open. The ensuing horde can provide enough of a distraction for the
Smoker and Hunters on your team to take advantage of.

*HUNTER TIP*
When the survivors leave that stairwell, they enter a wide open area.
Directly across from them is the safe room, though they must first
climb up a small hill to reach it. Your perch is directly on top of the
safe room building. You get a great view of the stairwell the survivors
are exiting from, and can land a 25 damage pounce from here if the
survivors are adequately distracted.

*HUNTER TIP*
The less common, less damaging, but less expected method of attacking
the survivors as they leave the stairwell is from the survivors' right
side. There is a fence that you can pounce over and take one by
surprise. All in all, you can expect a 10 to 12 damage pounce at best
from this location, but survivor teams hardly ever expect an attack
coming from that direction.

*SMOKER TIP*
This is one of only a very few rare occasions where it may be
beneficial to your team to spawn in front of the survivors. Simply drag
someone out of the stairwell if you can. It will force at least one
other survivor to come to the rescue...more than enough time for a
Hunter laying in wait to score a massive pounce from a high perch.

There are usually a lot of common infected in this area of the map. A
Boomer here can slow things down greatly if the survivors don't have a
pipe bomb. Odds are though, if the survivors are in decent health by
this point, they'll make it to the safe room.

*SMOKER TIP*
If you get the opportunity, drag a survivor off the ledge just before
the safe room. You can delay the team a little bit and allow the
Hunters to try and dish out some extra damage before that safe room
door closes.


**************************************************************
-------The Drains------- [L4DTOLLb]
**************************************************************

Immediately after leaving the safe room, the survivors have two
options. Run straight ahead, or make a right. Regardless, it's a common
survivor strategy to use the safe room's security and shoot through the
bars in the door to pick off as many common infected as possible. As
soon as the survivors leave the safe room however...

*BOOMER TIP*
Everyone expects a Boomer to attack from up above and to the right.
Instead, spawn behind one of the three large pillars in that room and
vomit on the survivors from there. This is helpful in two ways. 1) It's
less expected, so it's more likely to work.
2) You increase your range by spawning in the middle of the room.
You're not limited to attacking from just one corner.

If the Boomer gets his vomit attack off, the Hunters and Smoker on the
team need to get an attack off immediately. There is no real great
place to attack the survivors here as a Hunter...however...

*SMOKER TIP*
*HUNTER TIP*
Immediately out of the safe room, go to the left and spawn behind the
septic tanks. If the Boomer gets a good vomit attack off, try pulling
one towards the base of the ledge the septic tanks are on. This can
open an opportunity for a Hunter on your team to land a 16-18 damage
pounce from up above on the ledge to the right from the safe room's
exit.

If the survivor team decides to run straight ahead (which most survivor
teams do), they open themselves to big pounces as they enter the large
room. Hunters can pounce from the pipes overlooking the landing near
the bottom of the ladder. It's common to get 15-18 damage pounces here.
Boomers can also take advantage of the high ground and vomit down on
the survivors to create chaos.

*TANK TIP*
Every so often here, a Tank will spawn. Sometimes in this location, the
survivors will find tier 2 weapons, and they may have already picked up
a molotov. If you get lit on fire, run into the sewer water to put it
out and prolong your life. The water in the crescendo event room will
also extinguish the fire - even though if a survivor throws a molotov,
the water will still burn...weird.

If the survivor decides to take the right path out of the safe room,
they force themselves to climb down a ladder once they reach the wide
open. This choke point can be pretty tasty for Hunters.

*HUNTER TIP*
You can spawn across the room on a ledge facing the ladder, and if you
arc it just right, you can make it all the way across and pounce
someone all the way down, making them take not only at least 14-16 </pre><pre id="faqspan-4">
damage from your pounce, but also a bit of falling damage as well.

Separation is key here for Smokers. This is another one of those rare
instances where it can be beneficial to spawn ahead of the survivors as
a Smoker. Drag the first one down off the ladder if you can. This can
separate him from the team enough for a Boomer to puke from up above.
OR...you could spawn behind the team and try dragging the last
straggler back, forcing the survivors to climb back up the ladder, then
go back down. This can be a repeat for the previous Hunter tip, but it
makes it a bit more difficult for Boomers to attack.

Past the wide open room, the survivors will head into a short tunnel,
then into another wide open room. This is Death Toll's first major
crescendo event. The survivors must activate the bridge and wait for it
to descend while being swarmed by a mob of zombies. The common survivor
strategy here is for them all to huddle against the fence by the start
of the bridge and make a run for it into the small closet just past it.
That closet contains a medical cabinet that will contain a med pack or
pills. There is also always an ammo stockpile there.

This part of Death Toll has been altered to offer more balance for the
infected team. In the campaign mode, the ledge the survivors are on is
flush with the wall, and there are less entrances from the walls the
zombies can attack from. In VS mode, the ledge the survivors are on by
the bridge is spaced away from the wall, and can allow Boomers to
attack from below by arcing their vomit up over the walls.

After the event, the survivors will make their way along a narrow
walkway. There are railing here, but not along the entire path.

*SMOKER TIP*
Try your best to drag one of the survivors back down into the sewer
water. You'll force them to remake the trip. At the highest part of the
walkway, the survivor may take a minor amount (5 to 10) of falling
damage. This section here can be used to grind the survivors down,
though if a Boomer gets his vomit attack off, the survivors may just
huddle back into the closet that contained the medical cabinet.

*BOOMER TIP*
If the Smoker is successful in dragging a survivor off that walkway,
vomit on the Smoker's victim. If you vomit on the other survivors,
they'll likely huddle back in that closet. If you vomit on the pulled
survivor, he/she must make the trip through a mob of zombies. This is
part of the whole "grind down" process. The Hunters on your team can do
what they can to prolong the grind and possibly give the Smoker a
chance to respawn and start the whole process over again.

Past the crescendo event room, the survivors will enter more drains
that split in two paths. From what I've noticed online, there's about a
50/50 split up between the two ways the survivors can go. Regardless,
this is a great place to try and vomit on the survivors if you're a
Boomer. Hunters can't get big pounces here and Smokers leave themselves
open, but the chaos a horde causes may be enough of a distraction to
get some extra damage off.

*TANK TIP*
Odds are the survivors will have at least one molotov at this point.
Unfortunately, water is a bit further away than you might like at this
point in the map. If you get lit on fire...you're just going to have to
deal with it. However, this area is rather cramped. A horde summoned by
a Boomer here will give you PLENTY of time to catch up to a survivor
and repeatedly score hits. You can hit the pillars in one of the rooms,
but after a bunch of attempts against stationary targets, I found they
don't cause an instant incap. All they do is add a bit of clutter to
the room that forces the survivors to jump over. So don't go and try to
punch the pillars into the survivors. You're wasting your time.

The survivors can either climb up a ladder that leads to a small room,
or climb up a steel grating that will put that at the top of a hole in
the floor. Either way...time for some fresh air. And time for a number
of 25 damage pounce locations for Hunters.

*HUNTER TIP*
You can climb up the hillside on the right side after exiting the
building. As the survivors exit, arc your pounce and aim for the
entrance. It's a great place to land a 20-25 damage pounce. Also, on
top of the building, you can kind of blind fire and pounce up at a
steeper angle and try to land at the exit of the building. This won't
cause quite as much damage as the previously listed location, but it's
less expected from my experiences online. Most survivors will try to
hug the building while heading to the safe room, fearing large pounces
from Hunters, however, but don't count this location out yet. The
survivors must head out into the open for a short while to jump through
the windows leading to the safe room. From the front of that building,
you can land a 17-25 damage pounce depending on where you set up from.

*BOOMER TIP*
The survivors are close to the safe room, but that doesn't mean they
have to make it! A horde here may be enough for the survivors to slow
down and allow a Smoker on your team to pull one back, or Hunters to
get some extra damage off unless they have a pipe bomb in stock. Spawn
behind the wall in that building and you can easily get at least one
survivor.

*TANK TIP*
It happens, although rarely, but a Tank can spawn this late in the map.
There are numerous cars that you can punch to slam into the survivors.
Take advantage of them. A lot of survivor teams may head back into the
building they came out from to avoid you. But one of them may stand at
the exit of the building. You can climb up the front of the building
and run along the roof to drop in front of them!

If the survivors make it here with decent health, do whatever you can
to lower their health score, because they're probably going to make it
to the safe room.


**************************************************************
-------The Church------- [L4DTOLLc]
**************************************************************

Immediately out of the safe room, an ambush can take place. This is
widely expected by the survivors, so pulling it off can be rather
challenging if you're playing against a competent survivor team. It's a
wide open area they'll be entering, and as such, it's a Boomer's worst
enemy. A Boomer can *try* to vomit down on the survivors by climbing up
the building to the left out of the safe room (behind the train car)
and spawning directly above the survivors, but more often than not,
you'll get popped by someone expecting you to be there.

Truth be told, there really is no good place to cause a lot of panic
amongst the survivors in this area. Hunters have several locations
where they can score big pounces, but without a horde to hold them in
place for a few precious seconds, they can be extremely difficult to
pull off. And nobody likes landing mere inches away from a survivor on
what would have been a 20+ damage pounce.

*SMOKER TIP*
*BOOMER TIP*
One way you can try to combat this wide open area against a team of
survivors is to have a Smoker spawn directly above the safe room and
try to drag the last survivor back. As the Smoker is pulling the
survivor back, you can have the Boomer spawn in the same location to
try and vomit on the pulled victim. This may slow the survivors down
long enough for a few decent damage pounces from the Hunters on your
team.

There are two ways the survivors can go about this area. The safest way
is to hug the right side wall and enter the building. Inside, there may
be tier 2 weapons, propane tanks, or gas cans. Upon exiting that
building, the survivors are sheltered from the side by the wall and the
silos on their left. They must basically cram single-file through this
narrow passage way, and any Hunter that can spawn behind the team and
pounce as they exit the building can expect a 12-15 or higher damage
leap should he make contact.

The more dangerous way for the survivors to go is by staying out in the
open and checking the tower for supplies or tier 2 weapons. While there
aren't many locations for Hunters to land big pounces, the tight
walkways here can be treacherous for the survivors because the railings
can be destroyed.

*SMOKER TIP*
Smokers can pull victims off the ledges on that tower. They'll either
hang on or they'll fall. And you can drag someone from the very top all
the way down for an instant incapacitation in falling damage. But even
if they hang onto the ledge, it's still a great area as the survivors
will need to slow down and be careful in their descent. And remember,
slow moving survivors = easier targets!

*TANK TIP*
While getting a Tank this early on in the map isn't common, it does
happen from time to time. The wide open area in the trainyard is a
Tank's worst enemy. The survivors can spread out, there's no cover for
you, and if the survivors can make it to the staircase and balcony they
need to reach to proceed, it can complicate things tremendously for
you. Teamwork amongst your fellow infected players is essential here in
order to have a productive Tank. There is a forklift that you can bash
into the survivors for an instant incap, but know that it doesn't move
too far when struck. A horde here is your best friend if a Tank shows
up. Odds are, this early on in the map, the survivors won't have a
molotov, but gas cans are pretty common in the building to the right
out of the safe room and in the rooms behind the staircase on the
opposite side of the map across from the safe room. Be wary of what's
happening, and be sure to ask your teammates if they know of any
hazards you need to try and avoid. There is no water on this map for
you to extinguish yourself with if you get lit up.

Before taking the staircase up to the balcony, there are a few rooms
down below behind the staircase that can contain some items for the
survivors. The beauty here is that this entire area is a "grind" for
the survivors. Keeping them in this area can whittle them down little
by little. Spacing out your attacks can provide your teammates chances
to respawn and keep them around here.

The survivors must pass across a balcony that has several rooms in
which they can find goodies. One room from what I've noticed ALWAYS
contains propane tanks, but a 2nd pistol is a common pick up, and so
are pipe bombs from my experiences. The railing on the balcony is is
disrepair. There are a few sections where a Smoker on your team can
drag a survivor back down. While spawning here can be a bit
challenging, if you can get it off, you force one of them to re-make
the trip up the balcony.

*SMOKER TIP*
*BOOMER TIP*
*HUNTER TIP*
The balcony the survivors must traverse is very similar to the hospital
mezzanine in No Mercy. The problem here is spawning in areas in which
the survivors cannot "see" you. There are some thick trees over by the
tall tower that you canNOT spawn behind because technically still "out
in the open." You can try using the forklift as cover and crouching
behind that to spawn, but it doesn't always work. Regardless of how or
where you spawn, your goal here as an infected team is to keep them in
this area. Obviously, the Smoker will want to attack here first. Try
dragging a survivor down from the balcony. Then, the Boomer can try
vomiting on the survivor who was pulled. The ensuing horde may buy
enough time for a Smoker to respawn. If not, have the Hunters attack
the survivors one at a time to slow the team down for a few precious
seconds. Then you can try to do it all again. Rinse and repeat. If you
can keep the survivors here for more than a minute and a half, chances
are they'll burn up a couple of med packs. If a survivor gets pulled
off the ledge, Hunters, remember that you can get on top of the roof of
the building with the balcony. From up there, don't be surprised if you
can land a 25 damage pounce!

Past the balcony, the survivors will get back on solid ground and
travel down a street. Both sides of this street are littered with trees
that provide visual cover for your infected team to take advantage of.
There are a few tall rocks that can provide decent perches for Hunters
to use as well. This section is pretty wide open, so getting a Boomer
to vomit on the survivors can be a little difficult here. However,
there are a couple of choke points a Boomer can take advantage of.

*BOOMER TIP*
In the middle of the street, there is a School Bus that you can climb
up the sides on. Most survivor teams when approaching this will swing
far to the left in anticipation of a Boomer. If you climb up and over
the bus, it may juke the survivors long enough for you to vomit on at
least one of them!
Immediately past the school bus is a small shack that contains a
medical cabinet. There are usually some gas cans or propane tanks in
there as well. Puking on the survivors as they're inside there is more
effective than you think. For one, if there ARE gas cans or propane
tanks, a stray bullet can spell some pain for the survivors. But if the
team sticks inside that building until the blinding effect goes away,
know that Hunters and Smokers can attack through the window across from
the doorway.

Up the road, the survivors will come across a house. The road is
blocked so they must enter it. There is a garage off to the side that
usually contains some sort of goodies, but I rarely ever see survivor
teams checking it. It may be a good idea to not even set up there in
anticipation for the survivors. Inside the house, med packs, pain
pills, ammo, and gas cans are rather common. This house, however is a
decent area to "grind" the survivors. There are plenty of window that
can be jumped through to enter the house and attack from unexpectedly.
Obviously, Smokers here aren't quite as effective, but if you see an
opportunity to drag one back amidst some confusion, take advantage of
it!

Through the house, the survivors enter yet another wide open area.
There is an ambulance here that can contain a med pack, pain pills, or
an oxygen tank.

*TANK TIP*
A Tank spawning here is from what I've noticed the most common
occurrence. There are a couple of cars past the ambulance that can be
used to smash into the survivors. Because there's a lot of room here,
you will more than likely need to rely on your teammates. Also,
remember there is no water for extinguishing yourself if you get lit
up.

Past the ambulance, the survivors enter a cemetery (seems rather
fitting for a zombie game, huh?) and must make their way up to the
church. There is a shack near the entrance of the cemetery that can
contain goodies, most commonly gas cans.

*HUNTER TIP*
From atop the shack at the entrance to the cemetery, you can pounce and
reach the actual entrance the survivors must go through. My personal
best pounce here is 19 damage. But anything over 13 here is great!

The survivors are now at the end of the map...however, the guy inside
the church doesn't believe that the survivors are immune, and so as
sort of a "test" he rings the church bell which the zombies just flock
to! This crescendo event has an area for the survivors to cram into and
has been called to be patched to no avail as of yet. The location most
survivors will use (and the location that needs to be patched) is in
the room with the ammo stockpile. There are a few crates near a corner,
but spaced out enough for the survivors to huddle between the wall and
those crates. Zombies CAN climb on top of the crates to attack from
above - and truth be told, until this area is patched, it's probably
your best bet if you're a Hunter. Smokers and Boomers...well...you can
try to attack from the survivors' right side through that door to try
and get a melee swipe off, but that's all you can really do. For a
Smoker, it may be your best bet too. You can try to drag one of them
out of that corner from directly across from the survivors, but more
than likely, the survivors are just spamming their melee attack and
will break your tongue's hold before you start doing damage to them.

If the survivors reach the crescendo event, more than likely they'll
make it to the safe room because of the location they can huddle into
described above. The Church in VS mode is different from the church in
campaign mode. The roof breaks and the large boarded up section against
the back wall is now glass and can be broken. It allows for a couple
new angles the infected can attack from. Either way, the survivors will
likely stay in that location until after the event is over and head to
the safe room.

Looks like the guy inside the safe room wasn't immune after all! He
will turn into a random special infected to provide one minor last
obstacle for the survivors to deal with. If you can get an attack off
here to lower their health score, go for it because they're going to
make it.


**************************************************************
-------The Town------- [L4DTOLLd]
**************************************************************

In my personal opinion, Valve got really lazy when modifying this map
for VS mode. There are a ton of rooftops lining most of the level, yet
Hunters can't pounce up on most of them. Because the map is so large,
half the level doesn't even appear until after you progress through an
area, and traveling from rooftop to rooftop is impossible. There are a
lot of the red "out of bounds" barriers that shouldn't be where they
are - and they block access to more rooftops. Maybe it was a balancing
issue, but I don't see how. All that being said, it can be very
difficult for Hunters to land a pounce over 20 damage on this map.

Immediately, the infected team has an opportunity to grind the
survivors down.

*BOOMER TIP*
Since most survivors like to grab a Hunting Rifle and pick off as many
zombies as they can from this vantage point atop the church, try to
force them back into the safe room by vomiting on them! Since they're
still be in the safe room, you will respawn without a countdown timer.
Alert your fellow teammates to go in there and dish out as much damage
as possible to take advantage of the no spawning time. Boomers who
respawn more quickly can constantly keep the pressure on the survivors
by repeatedly vomiting on them. Hunters and Smokers can try to enter
and get a quick melee swipe off before dying. The little bit of damage
done here is free for your team because you can always respawn
instantly as long as they stay in there!

Once the survivors leave the safe room, there are three ways they can
go to progress through the map. The Town map of Death Toll is huge.
It's the longest single map in the game. Most survivor teams will take
any shortcut they can to make their lives easier.

1) The shortest path is for the survivors to jump on the brick wall and
fence in the church yard and walk along that, then jump over the bus
barricade.

2) The most common path (and medium length) is for the survivors to
exit through the gap in the wall near the white truck on their right,
then once in that open area, jump over the sandbags between the two
busses.

3) The longest path (and the one more littered with goodies) is to exit
through the gap in the wall near the white truck, then enter the
buildings across from them. Regardless of which way the survivors take,
as a Hunter, a 25 damage pounce is very attainable here.

*HUNTER TIP*
From atop the church, pounce onto the cross, then pick out a likely
target if you can. No matter which way the survivors go, you can land
an absolute monster pounce from here. A Boomer slowing the team down
here provides you an easier target. Landing one of these pounces is
very satisfying...and it makes you wish that the pounce damage wasn't
capped at 25! Beware though, that skilled survivor teams know of this
spot, and if one of them has a Hunting or Assault Rifle, your location
will be the first one they check! Try to take advantage of this area.
This is one of the few areas where a 25 damage pounce on this map is
attainable.

If the survivors take the shortest path (over the brick wall) do
whatever you can to get in front of them for an ambush. Taking this
path isn't common amongst survivor teams...thankfully. It can be a
little tough to react to an entire team using this shortcut.

If the survivors decide to go into the open area and jump over the
sandbags, it allows you and your team more of a chance to attack. The
Boomer on your team can set up behind the busses and lay in wait, the
Smoker has a chance to spawn behind the team and drag them back into
that wide open area, and the Hunters can take advantage of any
straggler, rusher, or unaware survivor.

If the survivors decide to enter the building directly across from the
church, you can try the "grind" strategy to whittle them down a piece
at a time while they're camping inside. There is a small office room
off to the side in the main building that the survivors may try
cramming into, and if they do, melee swipes become more effective. If
you're a Boomer, just try to keep them in that room as long as you can.

Back on the streets, the survivors have a fairly linear path that will
take them through a building. Along the street, there are a couple of
rooms off to the side that may contain goodies for the survivors, and
if everyone crams into one of those side rooms, try the "grind"
strategy again if you can.

*TANK TIP*
There are plenty of cars in this location, along with dumpsters you can
smash into the survivors. While this area is pretty wide open, there
are numerous obstacles that can hold the survivors up. However, these
obstacles can hinder the trajectory of whatever you smash their way.
Keep that in mind, as you may need to take an extra half second to line
yourself up before attempting to punch something their way. Otherwise,
this may be a decent area to try solely throwing rocks at them. Arc
them a little higher to get them over whatever obstacles are in the way
and you can still score hits.

Inside the building, there's usually some goodies or a 2nd pistol. Keep
an eye to see if the survivors have pills and molotovs/pipe bombs.
Because most survivor teams expect an ambush once they leave that
building, this is another one of those rare occasions where it may be
wise to spawn behind the team as a Boomer. Make them pay for taking too
long!

Once the survivors leave, they're in another open area, but there is
plenty of cover for the infected players to spawn behind. They'll
99.999% of the time hug the wall immediatey across from the exit they
came out of, and most likely check a room off to the side after
rounding the corner. This is another area where you can grind the
survivors down if they all cram in there.

The survivor team can enter the building off to the left to check for
supplies, but in order to advance, they must jump atop the white van
and walk along a ledge to enter an office building. Through that
building, the survivors have a good view of what they must do next. A
forklift is holding up a slab of concrete - which they will have to use
to make a path for themselves.

*HUNTER TIP*
Out of the office building, head to the far right and climb up the
building. This is a a great vantage point for you to use and try to get
one of those rare 25 damage pounces on this map!

This crescendo event can be rushed past. If you see the survivors
trying to make a dash for it, do whatever you can to spawn in front of
them and dish out some damage. They still have a little ways to go
before they reach the safe room, and with a horde on their tails,
slowing one of them down can allow the horde to catch up and slow
him/her down even more. A Boomer here can be extremely valuable as
well.

There are 3 common ways for the survivors to deal with this crescendo
event. Like I already mentioned, rushing past it is a viable option.
The 2nd method is to have someone activate it and then run all the way
back against the fence and huddle into the corner. This is actually a
much safer method for the survivors. Hunters, because of the crappy job
Valve did on this map, cannot get on any of the nearby rooftops to land
pounces. If they huddle in that corner against the fence, there isn't
anything you can do, unfortunately. There's no cover to hide behind,
it's wide open, and you have to go at them from one direction. It
really sucks...

The other common method of dealing with this event is to activate it
and then have everyone huddle into one of the bathrooms in the office
building. If the survivors do this, you can actually spawn in one of
the bathrooms beside the survivors...I can't come up with an
explanation to it, myself as of yet. Maybe just crappy programming at
this part. Either way, if the survivors huddle into the office
building, claw swipes are your best bet.

Regardless of what the survivors do at this crescendo event, one thing
is for certain. The horde that comes is HUGE! It's actually a 2 part
horde. After the initial wave, the "horde is coming" theme will play
again and wave 2 will start. Most survivor teams will already know
this, but if you see them starting to move after the first wave, get
ready to go in because a swarm of common infected are going to make
things a little more interesting!

*TANK TIP*
There are cars here to hit at the survivors. It's also a wide open
area, so if you need to, throw some rocks at them. It's rare to get a
Tank activated once the crescendo event starts...but sometimes THAT is
the trigger. If that's the case, take full advantage of the chaos and
pummel away! If you see the survivors still trying to huddle in that
corner next to the fence, chucking some slabs of concrete at them is
your best bet.

After the event, the survivors won't want to waste any time in
finishing the level. They'll make a mad dash over the balcony and try
to push as hard as they can to make it to the safe room.

*SMOKER TIP*
If you can drag one of the survivors back after the other three have
crossed over the dirt hill in the middle of the road, you can force one
of them to backtrack and aid their ensnared companion. Boomers and
Hunters can take advantage of this situation.

The survivors must pass around a bus and enter a narrow alley. There
are several rooms off to the side the survivors can enter to look for
supplies, but since this area is so close to the safe room, these
optional areas are often skipped past. Hunters can take advantage of
decent pounces (15-18) should the opportunity present itself as the
survivors pass through the narrow areas. They'll have to climb up a
staircase, then cross over a wooden plank before dropping down on the
other side of the chain link fence and pushing to the safe room.

*SMOKER TIP*
Drag someone back as they try to cross the wooden plank and you'll
force him/her to remake the trip. A Boomer can be useful here to help
grind the survivors down.

*BOOMER TIP*
As the survivors cross over the wooden plank, vomit on them from down
below. For whatever reason, most people tend to be more aware of what's
coming from above them than what's coming from below!

If the survivors make it over the wooden plank and drop on the other
side of the fence, odds are they'll make it to the nearby safe room.
Just do whatever you can at this point to lower their health score.


**************************************************************
-------Boathouse Finale------- [L4DTOLLe]
**************************************************************

Immediately out of the safe room, the survivors enter a garage where
Francis will likely say "I hate vans." Most survivor teams expect a big
ambush as they exit the building. This is an exiting location for an
ambush because there really isn't anything the survivor team can do to
thwart your scheme. However...

*BOOMER TIP*
Most survivor teams expect a puke shower as they leave the building. It
may be in your best interest to sacrifice yourself for the greater good
and puke on them immediately after they exit the safe room. You can
spawn behind the van or in one of the small rooms off to the left side
(out of the safe room). There is ALWAYS a pipe bomb on top of the army
humvee directly across from the building's exit, so getting a boom off
here may be more beneficial as the survivors will have to manually
fight off the ensuing horde instead of using a "get out of horde free
card."

The best survivor teams will not wait around. They'll not hesitate to
run as far out into the open as they can to try and pick off a Smoker
or Hunters laying in wait. Every survivor team expects a Smoker to be
on top of the roof. Instead...

*SMOKER TIP*
There is a bit of foliage you can hide your visual cue behind. It
offers less protection, but attacking from an angle the survivors are
unfamiliar with in this area can cause a little more damage than usual.

*HUNTER TIP*
The best locations for the big pounces here are unfortunately the most
commonly checked. The houses across the street are too far out of the
way to be viable. You may have to just bite the bullet and use one of
the obvious locations for a pounce and target a likely looking victim.
Be careful, however. Everyone will know you're there, and they'll be
keeping one eye open in your direction for sure.

The survivors must go through a house and enter the back yard to
proceed. Inside that house is usually a 2nd pistol, pills, or a med
pack. Upon exiting, the gas grill to the left will ALWAYS have a
propane tank in it.

*HUNTER TIP*
From the back door of the house, you can go to the right and climb on
the roof of the house next door. From up here, you can land a big
pounce. It's another common location survivor teams check, so there's
some risk involved. But you can reduce the amount of risk if...

*BOOMER TIP*
By the flaming barrel is a great place to spawn as a Boomer as the
survivors exit the house. If you can manage to get at least one of them
covered in vomit, you can make a survivor a very easy target for a
Hunter to employ the strategy listed above. All you'll have to do is
walk around the fence and let loose.

Across the wide open area is a shack that commonly contains pipe bombs
and molotovs. There's usually a gas can resting behind the shack as
well. The survivors will follow a dirt path along a cliffside that the
infected can climb up and enter a wooded area. The foliage here is a
godsend for Smokers and it can completely offset their visual cue.
Hunters can land monster pounces from atop that cliffside should a
Boomer's horde hold one of the survivors in place long enough.

Most survivor teams will head straight past the pavilion and enter the
boat house. However, there is also another small cabin off to the left
after passing that cliff. Inside may be pills, med packs, pipe bombs,
molotovs, propane tanks, or gas cans. It's really amazing to me that a
lot of survivor teams pass up this potential treasure trove!

*HUNTER TIP*
The pavilion is a great place to perch atop and wait for the survivors
to come by. You can easily pounce all the way towards the spotlight on
the ground in front of the boat house. Plenty of range for a 20+ damage
pounce!

The boat house has been dramatically changed from it's campaign mode
counterpart. There is a hole in the roof, there are no side rooms. More
walls can be destroyed...basically, it turns into swiss cheese! The
supplies have also been moved outside on the deck. Hardly anyone ever
uses the mounted machine gun on the balcony. Most survivor teams will
take one of two common locations to dig themselves into and hold off
the horde.

The first common location is on the 2nd floor of the house, with 2
survivors huddling into one corner behind the staircase and the other 2
huddling into the corner to the left of the staircase. It can be
difficult to get a lot of damage on the survivors as a Smoker is unable
to drag someone out of the windows, and Hunters will need to rely on
quick 6 to 10 damage pounces for the most part.

*HUNTER TIP*
It can be frustrating if the survivors try using the 2 corner strategy.
However, if you can easily perform wall jumps, you can pounce up the
staircase directly at the wall, then wall jump off after turning 180
degrees and land on someone in the corner behind the staircase. Don't
expect a lot of damage out of it, but it can be potentially more than
what you can expect from a claw swipe or two.

The other location the survivors commonly camp in is directly
underneath the deck outside the house. This forces the infected to
charge at them from only 2 directions, though they are considerably
further away from supplies should they need to heal up.

*SMOKER TIP*
If the survivors huddle underneath the deck, you can run around towards
the front of the house and if you position yourself just right, you can
actually get your tongue attack off through the small gap between the
ground and the bottom of the house. Don't expect a lot of damage out of
it, but you may buy the Boomer on your team enough time to vomit on at
least one of the survivors.

The Death Toll finale event, like the other campaigns follows a
pattern.
1) Horde
2) Tank
3) Horde
4) Tank
5) Last ditch effort horde + Tank.

When it's the Tank's turn to show up, the very...very...very common
survivor strategy is for them all to run out into the water behind the
boat house and take advantage of the wide open area with no movable
objects anywhere close to them.

*TANK TIP*
If you get lit on fire, run into the water to extinguish it. If the
survivors run out into the water, your best bet is throwing rocks at
them. No use getting filled full of lead while trying to catch up to
someone with no obstacles to block their escape.

*HUNTER TIP*
The survivors will more than likely head out into the water to deal
with the Tank. As a Hunter, you cannot pounce while submerged in the
water. However, what you CAN do is crouch in the water and get close to
the survivors - take a swipe from behind one of them - then crouch
again to hide. Be aware that while you're crouching in the water, you
WILL start to take some drowning damage after a while, so every so
often, pop your head above water and then immediately crouch. Hunters
get so low to the ground that they cannot be seen by the survivors
unless they crouch...and why would you want to crouch while a Tank is
also attacking!?

After the boat arrives, the Smoker on your team is a godsend if you can
manage to drag one of the survivors off the pier. You force that
survivor to make the trip again, and that can give your last ditch
effort Tank enough time to catch up and score some hits! If a Tank can
catch up to the survivors on the boat, you can actually send them
flying off the rescue vehicle! This can spell a kill for the infected
team. The boat takes a while to actually arrive, so it's easier to
knock a survivor off the boat as you have more time to try and get
there. It also allows a Smoker more time to drag one of them off the
pier - where the ensuing horde will proceed to pummel the unfortunate
victim.

Now make the survivors pay their Death Toll.


**************************************************************
-------Dead Air Overview------- [L4DAIR]
**************************************************************

Dead Air is quite possibly the most played VS map in Left 4 Dead. It's
very infected-friendly because of it's many choke points, high perches
for Hunters, movable objects for Tanks, and cover in most of the wide
open spaces for Boomers to hide behind.

Dead Air takes place at sunset. Because of the orange hues in the sky,
it can make finding a Hunter waiting to ambush fairly easy for the
survivors. The silhouette a Hunter puts out against the orange sky
sticks out like a sore thumb, and in a lot of locations, there really
isn't anything you can do about it. As a Hunter, try to take note of
objects such as chimneys, pillars, billboards, etc to try and mask your
silhouette by hiding in front of them. Sometimes the survivors may not
even notice you until it's too late! Just be sure to not go out of your
way and pass up a practical damage opportunity for the sake of stealth.
Remember that as the infected, you are going to die...a lot. Also keep
in mind that if there are bots on the survivor team, they can still
"see" you, even though the human controlled survivors may not.

In spite of the time of day, Dead Air is actually a fairly dark
campaign on most of the maps. Like No Mercy, there isn't a lot of thick
brush to hide a Smoker's visual cue, but on the up side, a lot of the
wide open areas are littered with objects to hide behind until you're
ready to attack. Boomers can find this helpful as well. Tanks will
enjoy the large amount of movable objects, especially on the 3rd and
5th maps in this campaign. The Terminal section of Dead Air is the only
map that is pretty well lit.

Dead Air is a fairly short campaign with one of the maps allowing the
survivors to complete in less than 5 minutes on average. The Finale map
is also extremely short as there is basically no hike leading towards
the event. Perhaps this contributes to the campaign's popularity...
Maybe, maybe not.

Dead Air has three major crescendo events aside from the finale. One of
which can be rushed past by the survivors, but the other two require
them to sit and wait until the path is clear. One of those events that
cannot be skipped past has a camping spot that has been called to be
patched with no results as of yet.


**************************************************************
-------The Greenhouse------- [L4DAIRa]
**************************************************************

The first map of Dead air begins inside a large greenhouse usually
swamped with common infected. There really isn't a great location to
ambush the survivors immediately, and most survivor teams will clear
out the room before jumping down and continuing forth. Outside is where
you will want to ambush the survivors. There is a choke point that must
be crossed, and although brief, it's really a treacherous place for the
survivors to be in should one of them get incapacitated.

This map is extremely short - taking the average survivor team less
than 4 minutes to complete it on VS mode while NOT rushing. There are -
thankfully - a few choke points and grind locations to take advantage
of to keep the survivors within the field of play.

*BOOMER TIP*
There really isn't a great location to always set up as the Boomer at
the beginning of this map. The survivors could exit through the windows
or the door. One of the most common spots to set up is in the corner
between the two outside the greenhouse. That way, you can attack them
no matter which exit they take. The problem is, if you do get a vomit
attack off here, odds are the survivors will simply retreat back into
the greenhouse and wait until the coast is clear. Instead, it may be
wise to save your spawn until...

*SMOKER TIP*
The choke point at this section of the map is the narrow wooden plank
the survivors must cross over to reach another rooftop. There are two
locations you can set up to pull a survivor into an instant incap. The
first location is down below - between the buildings, and stand on top
of the garbage dumpsters. As a survivor crosses, use your tongue attack
and try to pull one over the edge. The second location is across the
wooden plank on top of the building by the water tower. Try dragging a
survivor as they cross the plank there to get an instant incap. If all
goes well with this ambush...

*HUNTER TIP*
You can pounce on top of the water tower on the building across the
wooden plank. It's a VERY common location to attack the survivors from,
so make sure you stay on the back side of the tower until you're ready
to attack. A survivor pulled by a Smoker's tongue over the edge will
require a teammate's assistance. 5 long seconds for you to line up and
execute your 25 damage pounce!

*BOOMER TIP*
If you saved your spawn and the Smoker pulled someone over the edge,
there is enough cover across the wooden plank to spawn behind and puke
on the survivors. The ensuing horde will complicate the rescuing of the
incapped survivor and can give your Smoker a chance for his tongue
attack to recharge - or respawn completely so that he can try it again!

Across the wooden plank, the survivors will enter the building and may
possibly find pills, a med pack, and a 2nd pistol. Molotovs and/or pipe
bombs may also be present. The survivors will have to exit through the
windows and onto another rooftop in order to proceed.

*BOOMER TIP*
Fearing an ambush, a lot of survivor teams are hesitant to simply
charge headstrong out the windows and climb the ladder to their right.
This is one of those rare occasions where it may be beneficial to spawn
behind them as a Boomer to try and make them pay for not advancing.

*TANK TIP*
Getting a Tank here usually results in the survivors backtracking into
the building. However, if one of the survivors is out on that rooftop
past the windows, you can punch them off the building across from the
ladder. HOME RUN! If the survivors backtrack through the building, you
can still hit a Home Run, but it can be more difficult. What you CAN
do, however, is hit a survivor into a corner fairly easily and continue
to pummel him/her.

*HUNTER TIP*
*SMOKER TIP*
The survivors, on the rooftop leading to the short ladder make
themselves vulnerable to a very potent Smoker + Hunter combination that
I've dubbed the "Piledrive." Because there is a gap between the rooftop
and the taller building directly across from the windows the survivors
exit, a Smoker who pulls one of them off the rooftop will leave them
dangling above the ground some 70+ feet below. If the Smoker's tongue
gets destroyed while the survivor is hanging, or if the Smoker dies,
the survivor will fall to an instant incap by hanging onto the ledge.
However...if a Hunter is able to pounce on that dangling survivor, the
opportunity to grab onto the ledge is lost for the survivor, and since
the Hunter's pounce breaks a Smoker's tongue, all that can happen now
is a plummet to an instant death!

Up the ladder on that rooftop, the survivors will reach a few ledges to
jump down. This is a major damage dealing location - and while the
opportunity you have here is very slim, a Smoker pulling a straggling
survivor back after the other 3 have descended will result in a kill as
the others will not be able to return and save their teammate. Hunters
can accomplish this as well, but the Smoker can pull a survivor back
and out of the range of rescuing survivors jumping and spraying bullets
your way. If the Smoker DOES pull a survivor back, it may be wise for a
Hunter to pounce on the victim as soon as the survivor is beyond
rescue. Reason being, the Hunter dishes out damage much faster than the
Smoker can, and then the Smoker is free to try and separate the
survivors again later on in the map.

Down those ledges, the survivors will enter another building and head
down a staircase. They'll proceed to jump out of the windows and on top
of a semi truck. In this area, there is an alarmed car to be taken
advantage of if at all possible.

*HUNTER TIP*
In the open area past the kitchen, there are a plethora of high perches
for Hunters to score huge pounces from. If you're comfortable with wall
jumping straight up, the building immediately to the left out the
kitchen windows has some green awnings you can pounce on. From there,
put your back against the wall and pounce straight up. While in midair,
tilt forward about 10 degrees or so and pounce again. The entire time,
you should be trying to move backwards ("S" by default). You should
land on the very ledge of the roof (this is the only section of the
roof you can be on). From there, you can walk a bit to your right and
perch atop the white outcropping. From that vantage point, you can make
it all the way to the top of the semi truck. Timing your pounce here is
crucial, but it's a guaranteed 20+ damage haymaker! If you're not
comfortable with timing the pounce while the survivors walk along the
semi truck, you can also pounce all the way down to the alarmed car in
front of the building with the safe room. With a horde from either the
alarmed car or a Boomer (or both) you may get a fairly stationary
target to pounce on.

*BOOMER TIP*
There is plenty of cover outside for you to spawn behind and try to
puke on the survivors from. Once the survivors get inside the building,
the safe room is right in front of them. Keeping the survivors in the
open area is the best way of stopping them before they end the round.

*SMOKER TIP*
You can spawn in the building directly below the survivors. It's not a
common location that I've seen a lot of survivors check, so it may be
beneficial to pull a survivor back. Doing so may also provide a good
target for the Boomer on your team to puke on - which in turn will help
the Hunters waiting for big pounces to present themselves.

Inside the building, the safe room is very close. If the survivors are
in good health here, odds are they'll make it in. Just do what you can
to lower their health score. A Smoker here can sort of delay the
inevitable, but if there are Hunters ready to spawn and pounce, you can
complicate things greatly. The hallways to the left and right of the
safe room don't provide a lot of cover to hide behind and spawn, but if
you get the opportunity to - act quickly and you might be able to land
a pounce at the last minute.


**************************************************************
-------The Crane------- [L4DAIRb]
**************************************************************

Immediately out of the safe room, the survivors enter one of the most
notorious ambush locations in the game. The wide open area and ladder
choke point here cause many survivor teams to stop at the dock doors
and scope out the area before venturing forth.

*HUNTER TIP*
A great way to potentially complicate things for the survivor team
later on in the map is to climb up the building to the right just out
of the dock doors. Once you're able to spawn, light yourself on fire
using the flaming barrel and jump on top of the gas cans sitting on the
wooden crates near the edge of the building. It will ignite them and
therefore they won't be there for use later on in the round.
Unfortunately, there is no way to douse yourself, so you'll have to go
in for a quick attack. Just advise your teammates you're doing it so
they can attack alongside you.

*BOOMER TIP*
You don't want to be a Boomer here. Seriously...you don't! The wide
open area and easy retreat back into the building make any kind of
damage output from an ensuing horde very little, if non-existent.
Instead, immediately as the survivors exit the safe room, spawn behind
the boxes and try to vomit on the survivors as they run towards the
dock doors. Odds are your horde won't dish out any damage, but figure
that even 5 damage here against one of them is better than nothing.
Take what you can get. 90% of the time, you will respawn as a Hunter.
Because many survivor teams are still skeptical about leaving the
building fearing huge pounces, it may shave some times off your respawn
countdown and allow you to get into position... Alternatively, you
could also try climbing the pipe on the building to the right just
outside of the dock doors and puking on the survivors down below, but
so many survivor teams expect an ambush coming from that direction that
you may get popped before scoring a hit on one of them.

*HUNTER TIP*
There are 3 popular locations here to land a 25 damage pounce. The
first location is directly across from the exit of the building, atop
the roof. There's adequate cover for you, and you can cover most of the
ground in that area with a single pounce from that location. This
includes the corner immediately outside the dock doors, the ladder, and
if your pounce is angled just right, you can actually land inside the
building - on the ledge by the dock doors. This can be a very
unexpected 25 damage pounce on the survivors as they try picking off
any zombies loitering around or scanning for infected waiting to
ambush. Jump the gun from this location though, and you're probably
toast. The second location is from atop the crane. You're way high up,
and if you stay near the back side of the crane, you're pretty much
invisible. The problem with this location is that it forces you to
spawn in order to get into location. The advantage to this location is
the sheer range you have. You can pounce to the ladder, you can pounce
to the dock doors, you can pounce to the far corner opposite the
ladder, and if you angle your pounce just right, you can pounce to the
small room inside the building to the right of the ladder. The third
location is across the fence and atop the building to the right of the
ladder. This location allows for huge and unexpected pounces as the
survivors leave the building. Most survivor teams usually check the
crane to see if a Hunter is going to pounce from there, and they expect
pounces from straight ahead. They usually seem to forget that a Hunter
can travel great distances with a pounce, and neglect to check to their
left as they leave the building. The problem with this location is that
you make yourself less effective as the survivors come to the ladder
choke point.

This section of the map can be treacherous for the survivors. Huge
pounces here from Hunters can cripple the team, and if a survivor is
pulled back before jumping over the fence while the other three have </pre><pre id="faqspan-5">
crossed, they have no way of returning to help their teammate. An
incapacitation here with the three other survivors on the opposite side
of the fence spells an instant kill.

Now the survivors must come up to the biggest major choke point of this
map. The ladder. That notorious ladder. Hunters can take advantage of
the first two locations listed above for great opportunities for a 25
damage pounce while the survivors cannot draw their weapons on the
ladder. However, the biggest contribution to the infected team here is
the Smoker.

*SMOKER TIP*
I hope you didn't attack immediately. From out of the safe room, climb
up the building to the right of the dock doors and enter the building
through the windows to your right after reaching the rooftop. After the
survivors exit the safe room, spawn, and start using your claw swipes
at the wooden boards on the windows. One of these windows provides the
perfect location to your attack. Make sure to destroy all of the boards
on BOTH of the windows, as a Smoker can take advantage of this later in
the level. This is a VERY common location or Smokers, and as such, many
survivor teams will look up in this direction after entering the wide
open area. Just hang back and wait until the survivors climb the
ladder. This is where you come in. You want to drag a survivor back
from the top of the ladder - and you CAN reach the survivors from the
window closest to that ladder. One of two things will happen. 1) The
survivor will be dragged back but drop, usually slamming into the fence
and therefore taking a modest chunk of falling damage. 2) The survivor
will be dragged back without dropping OVER the fence and be hanging
about 30 feet above the ground. THIS is what you want. Technically,
it's a glitch, but it's been around since the game's launch, and I
believe that Valve either can't do anything about it, or doesn't know
what to do about it. Either way, if a survivor is hanging from that
high up, killing you or breaking the tongue will result in that
survivor dropping into an instant incapacitation...and since the other
3 survivors are most likely on the other side of the fence, they have
to leave their friend behind. Instant kill.

So that's the choke point. It's a very dangerous place for the
survivors when they're dealing with a skilled infected team. Many
matches on this map end here - but if they make it past, fear not, this
map is rather large and you will have a number of opportunities to take
care of the survivors.

Past the ladder, the survivors will enter a bathroom, then a bedroom.
The bed is a common place for tier 2 weapons, and the various
apartments that branch off the main hallway are usually stocked with
goodies.

*HUNTER TIP*
In these small apartments that branch off the main hallway, med packs,
pain pills, molotovs, pipe bombs, etc are commonly found. A lot of
survivor teams will check these rooms. You and another Hunter can take
advantage of the survivor team's curiosity by waiting in one of the
bathrooms (where pills are commonly found). Have one Hunter pounce on
the survivor immediately, then as another comes to the rescue, the
other one can pounce a different survivor. These apartments are pretty
dark, and therefore a great place for a surprise attack!

Past the hallway, the survivors will head up a staircase and enter
another apartment. This is another common place for tier 2 weapons, and
most of the time, an ammo stockpile will be found here as well.

*SMOKER TIP*
Remember when I said to break the boards on both of the windows in the
previous Smoker Tip? Well, this it comes in handy again. There are 2
locations you can try dragging a survivor out of the window from. The
first location is directly across from the windows - climb up the pipe,
then spawn and jump on the white blocks to the right of the crane. This
location allows for more range to pull someone back. The problem is,
you make yourself a pretty easy target. However, if you pull someone
out of the window, you instantly incapacitate them. The second location
is from down below. This location has a much smaller window of
opportunity, but next to NO survivor teams will check down below. If a
survivor strays too close to the window, have at it!

The survivors must now start the crescendo event in order to proceed.
They must use the crane to lower a dumpster with a ladder on it so that
they can make it across to another rooftop. After pulling the lever on
the crane, there are two common locations the survivors will camp until
the action dies down.

The first location is on the ledge of the crane itself. There are
always some gas cans around here for the survivors to ignite, which
they commonly do at the base of the ladder - unless of course a Hunter
ignited the gas cans at the start of the round. A Smoker here can drag
one of the survivors into the fire for additional damage, and if any
other survivor comes to the rescue, they'll burn as well. Boomers can
take advantage of the structure immediately across from the crane. It
provides cover to spawn behind and puking on the survivors here will
delay them even longer. To get the most out of your Boomer, puke as you
see the dumpster near the end of it's descent. It will draw another
horde and allow your teammates to get into position or shave some
seconds off their respawn timer. Hunters usually have a pretty tough
time getting any kind of decent damage if the survivors stake out in
this location. They're all bunched together, the infected have to
attack from one direction, and they will generally be spamming their
melee attacks. However...Hunters, fear not, for there is hope for you!

*HUNTER TIP*
If the survivors decide to all cram onto the ledge of the crane, they
make themselves stationary targets for a short while. On the highest
part of this rooftop, there is a tall metal beam that you can pounce to
the top of. From there, you can land a pounce upwards of 20 damage if
you aim it correctly. I find it better to aim for more distance here
rather than height because I kept falling short of my targets and that
put me in a bad situation being easily seen by the now nearby
survivors. Best to aim for more distance and pull back on your pounce
as you approach the survivors to drop in on them. You have to aim it
juuuuust perfectly, but it can be done, and it makes them pay for
camping in that area!

The second location is back inside the building. This provides another
opportunity for the Smoker to take advantage of the strategy listed in
the previous Smoker Tip - and it allows for a couple different angles
for which Hunters to attack the survivors from. Don't get me
wrong...this can be a frustrating camping site for the infected, but
remember that it forces their team to backtrack a bit, and therefore
allows for a 2nd opportunity for your team to take as the survivors
once again enter this area.

*TANK TIP*
The survivors will have to cross a number of rooftops, and if the Tank
spawns inside the building, odds are the survivor team will backtrack
onto those rooftops. Home Runs are common here. Obviously a Boomer's
horde helps tremendously, as this is a fairly wide open area, but there
are so many areas a Home Run is possible - and and such, alert your
teammates to KEEP THEM ON THE ROOFTOPS if at all possible.

After the event, the survivors will cross from rooftop to rooftop and
enter a building across the gap the dumpster bridged in the event. From
the 2nd rooftop after the survivors climb the dumpster, in the far left
corner is an area where the survivors can (and usually do) shoot the
alarmed car down below. They'll camp in that corner until after the
panic event, and the alarm is now a non-issue for when the they'll pass
by it later (if they make it that far). Hunters are usually the only
infected that can attack the survivors when they camp in this location.
One survivor will probably turn to face the pipe on the side of the
building and melee any zombie that climbs up to the roof as soon as
he/she sees them, so I wouldn't try sneaking up behind the survivors as
any zombie if they camp in that corner.

*SMOKER TIP*
Across the gap the survivors need to cross when going through the
crescendo event, there is a building you can climb into. As the
survivors are on top of the dumpster (and it's a pretty narrow window
of opportunity) try dragging one of them off. If things are NOT in your
favor, the worst that can happen is an instant incap as one of them
will be hanging onto the ledge. However, if you get your tongue attack
off in just the right location, you will drag them off the dumpster,
between the two buildings, and they'll be dangling a good 100 feet or
so above the ground. Survivors will NOT grab onto the ledges of the
dumpster and be instantly incapped. If the Smoker dies or the tongue is
broken while the survivor is dangling, the survivor will die from the
fall. You can also achieve this instant kill pull from near the burning
barrel at the base of the crane, but you expose yourself too much and
are an easy target.

*SMOKER TIP*
*HUNTER TIP*
Across the rooftops, the survivors will enter an office building and
will cross a wooden plank connecting to another nearby building. A
Smoker *can* drag someone into an instant incap from the dumpsters down
below, but the opportunity from that angle is so small, it's hardly
ever successful. Now, a Smoker can spawn behind the team on the
building outside and try to drag someone at an angle back over the
wooden plank to instantly incap a survivor more easily, but chances are
you won't live too long after that! Hunters can land a 7-10 damage
pounce from the lower building's roof to the wooden plank. It's not
great damage, but it can be rather unexpected to see a Hunter coming
from that direction.

In this building, the survivors come across a medical cabinet, and a
common location for tier 2 weapons, along with an ammo stockpile. They
must descend a staircase and enter a room mazed with cubicles, then
descend another flight of stairs and enter another room mazed with
cubicles...a Boomer's dream. There is cover a plenty to spawn and
crouch behind.

*TANK TIP*
Getting a Tank here - especially in the 2nd cubicle room can be lethal
for the survivor team. The cubicles alone are enough to hinder the
survivors' progress. Combined with a Boomer's horde, the zombies make
traversing these rooms slower than a sedated turtle running against the
wind. Plenty of time for a Tank to come in and show the survivors who's
boss!

Hunters will find the office cubicles easy to conceal themselves in,
but there are no good locations to dish out noteworthy damage. It may
be in a Hunter's best interest to go for claw swipes in this area. The
survivors will have to enter another wide open area before the level is
over, but for now, go for claw swipes as they'll more than likely deal
more damage than a close range pounce. The survivors here are almost
always closely bunched together - a claw swipe may hit more than one
survivor. A pounce only damages one.

Smokers find the cubicle rooms a nightmare, and the only thing to
offset the disadvantage for them here is the cover that will conceal
their visual cue. Dragging a survivor in this location is almost always
futile, unless a Hunter on your team (or 2 Hunters) is (are) prepared
to pounce on survivors coming to the rescue. Pulling this tactic off
can be difficult and frustrating. Smokers will generally find it more
beneficial to just stay behind and try to force the survivors to
backtrack a little bit after they reach a staircase.

After the 2nd cubicle room, the survivors are on ground level with a
safe room across the street. There is an alarmed car here. If the
survivor team activated the alarm from the rooftop, then just try to
pull a survivor back if you're a Smoker. Otherwise, try dragging a
survivor into the alarmed car.

There are several locations a Hunter can pounce from as the survivors
leave the office building. There are 2 ways the survivors can take out
of the building, and a number of ways the survivors can navigate the
wide open area leading to the safe room.

*HUNTER TIP*
Each location here offers it's own ups and downs. Most survivor teams
will choose to exit through the front door. There is a concrete awning
above the stairs leading into the building that will thwart most big
pounces as the survivors must be attacked from what seems to be only
two directions. However, there is a light pole across the street that
you can pounce up onto. If you can angle your pounce just right, you
can land a 16-19 damage pounce on a survivor before they even get on
the street.

If the survivors look like they're going to just cut across the street
and take the shortest path to the safe house, a 25 damage pounce can be
achieved here as a Hunter.

*HUNTER TIP*
On top of the storage space building, there is a roof with 2 tiers. You
can climb up to the first roof, but you will need to pounce onto the
2nd tier. You'll be able to walk along the rooftop, but against an
invisible wall. You can pounce all the way to the alarmed car from
here. 25 damage guaranteed if you land it.

If the survivors look as though they'll take the rear exit (which most
survivor teams don't) you can set up for a huge pounce by climbing the
pipe on the building at the back end of the long alleyway. From up
there, you can reach the end of the alley for a 25 damage pounce as
well. Another common location is on top of the building just past the
crane. This location can allow for an unusual angle to attack the
survivors from, and I've yet to see a survivor player anticipate an
attack coming from that far to their left. 25 damage pounces from this
location are rather common as well.

*BOOMER TIP*
This is a rather wide open area, but there is cover to spawn behind.
Try to attack quickly. The ensuing horde may show up in time to slow
the survivors down and make them easier targets for Hunters waiting for
huge pounces.

Inside the storage building, the survivors must make only a short run
to the safe room. If they make it here, odds are they'll waltz into the
safe room. Just try to get whatever damage you can done to them before
they end the round to lower their health score.


**************************************************************
-------The Construction Site------- [L4DAIRc]
**************************************************************

Map 3 of Dead Air allows for a possible "grind" location right from the
get-go. Smart survivor teams will dash out of the safe room and take
whatever beating is coming to them from an early ambush. However, some
survivor teams, fearing an ambush will hesitate to leave. Make them pay
for it.

*BOOMER TIP*
Getting your vomit attack off before the survivors leave the safe room
usually results in them backing into a corner in that safe room to deal
with the horde. This is a great grind location if the survivors think
they can weather the horde. Hunters and even Smokers should try to take
advantage of the instant respawn times by going in and try to get off a
claw swipe. Boomers can try to keep the pressure on the team through
constant hordes. You'd be surprised how much damage you can inflict by
keeping them in that safe room! There is a small room you can spawn in
just above the survivors that provides a good ambush location.

Once the survivors leave the safe room, they can head either left or
right. Most teams will dash to the left. There may be goodies to the
right, but since this map is rather long, the survivor mentality is
"let's get this over with!" To the left, there is a small staircase
leading to a platform that may contain tier 2 weapons.

*HUNTER TIP*
I've seen a lot of Hunter players spawn atop the building the survivors
leave right in the beginning hoping for big pounces as they make their
way down the narrow hallway. The problem is, there are several zig-zag
staircases that can obstruct you, as well as a fence section. If the
Boomer was able to vomit on the survivors, you can try going in for a
quick attack, then. A good 25 damage pounce location is atop the
building the survivors exit the safe room from. Head around to the back
and you will see a narrow gap between two buildings with a fence. You
have to time your pounce well, but if you arc right, you can make it
all the way to the "T" intersection. It can really throw some survivor
teams off, and it's good damage if you manage to land it. It *is* a
rather small window of opportunity, so you may need to practice your
timing, but it is possible, and many survivor teams don't expect a
pounce coming from that direction.

Moving on, the survivors will enter the actual construction site area.
There are stone pillars with metal wires atop them that Hunters can
pounce up onto. Some of these pillars require the use of vertical wall
pounces.

To wall pounce straight up against a flat surface, put your back
against the wall and pounce straight up. While in mid-air, you'll want
to be holding the back button the entire time ("s" by default). Angle
yourself forward 10 degrees or so and left click again. You should
pounce almost straight up. Because you're holding back, you can stick
to the wall and continue the chain. Getting up on those pillars usually
won't require more than a single wall pounce.

*HUNTER TIP*
On top of those pillars, you have incredible range. Take advantage of
it and realize that you can arc pounces over the wall between the
construction site and the alleyway. 20+ damage pounces can be rather
common here if timed well.

*BOOMER TIP*
Depending on where the survivors go as they enter the main contruction
site area, you can vomit on them and slow the team down significantly.
The many walls and other barriers in this area can potentially separate
the survivors and allow your teammates to dish out extra damage. If the
survivors climb the ladder leading atop the scaffolding, you can vomit
on them from down below. Keep in mind that they will be starting a
crescendo event soon, too.

The survivors must ignite a grouping of gas cans positioned at a
barricade between two buildings. This crescendo event draws a large 2
wave horde. There are a few common locations where survivor teams may
try to weather the ensuing event.

The first location is behind the scaffolding with the ladder near the
entrance to the site - under the pipes. This location can be rather
frustrating for Hunters as they're walled in on 5 sides. Smokers can
*try* to get a pull from through the scaffolding bars, but don't expect
much, if any damage out of it.

That location, for what it's worth can actually double as a "grind"
spot. The common infected may get a few hits off here and there. The
Boomer on your team should monitor the horde coming, and once it ends,
vomit on the survivors when they look like they'll make a run for it.
This will keep the pressure on them, and the other infected players can
try to do whatever they can to dish out damage while the survivor team
is stationary. The survivor team must also run through the construction
site as well, so Hunters can try setting up for big pounces as they
emerge from their shelter.

The second location is underneath the partially finished building in
the middle of the construction site. Survivor teams will usually split
up into 2 groups and cover opposite corners. There are some cable
spools near - but not flush against a wall that limits the direction
infected can attack them from. If you see the team split up against the
windows, however, they make themselves easy targets for a Boomer's
vomit attack. Unfortunately for Hunters, they're well sheltered, and
pouncing on them here will not result in much damage. You'll be better
off going for claw swipes instead. They can hit multiple targets, and
if you get more than one swipe off, you'll probably dish out more
damage than you would have with a pounce.

The third location (and one I never really understood) is in the corner
on the opposite side of the wall the barricade is burning down. The
survivors are protected from 3 directions. Underneath, behind, their
left, and their right. This leaves in front of them, and straight down
on top of them. It's getting rarer to see survivor teams huddle in that
corner, but if they do, they make themselves non-moving targets for
Hunters to 20+ damage pounce all through the event.

If the survivors take that corner, a good place to spawn as a Hunter is
by the scaffolding with the ladder. Pounce up to the circular tower,
then pounce across to the beam atop the concrete wall in front of the
survivors. Arc your pounce a little higher up than you normally would
and move slightly closer. This will help you come straight down on
them. Because the survivors will most likely be preoccupied with the
horde coming from straight ahead, it's rather easy to land these
monster pounces. Throughout the event, don't be a bit surprised to see
18-25 damage pounces appear at least 5 times! Let your teammates know
what to do, and where to pounce from.

*SMOKER TIP*
After the event, the survivors will likely be low on ammo and there is
ALWAYS an ammo stockpile at the corner down the alley past the burned
barricade. You'd be surprised how many survivor teams rush ahead
without checking behind them first...

*TANK TIP*
Because Tanks generally spawn a good distance in front of the survivor
team, you may spawn behind the barricade. There is a pipe that you can
climb just behind the barricade. Once at the top, you can jump across
to the pipes on the other side of the alley and cross it from there.
There are dumpsters that you can smack into the survivors for insant
incaps, and the maze-like setting here just begs for a Boomer to join
in the fun.

After the event, the survivors will move down a narrow alleyway with 2
rooms off to the side that may contain goodies for them. There is
ALWAYS an ammo stockpile at the corner before they'll be making a left.
All throughout this alleyway, Hunters can land huge pounces, and
Boomers may find the platform up top just past the left turn in the
alleyway an ideal place to vomit on the survivors from.

Eventually, they'll reach a rather wide open area that makes a Boomer's
horde that much more dangerous, and an encircled survivor is a sitting
duck against a Hunter's pounce from any of the nearby rooftops. There
is a room the survivors can enter to the left after exiting the
alleyway which will provide shelter, but the whole "grind" tactic can
come into play here.

The survivors will then enter the power plant section of the map. Most
teams will stay on the grassy areas, but be aware that they CAN pass
through the high voltage sections as a shortcut.

*TANK TIP*
Getting a Tank here is just cruel on the AI Director's part. If the
survivors are already in the building, then you have a chance at
hitting the forklift into them. If not...(and most teams will
backtrack) you will have to rely on your teammates to cause
distractions for the Tank.

Inside the building, the survivors come across a treasure trove of
supplies. Ammo, tier 2 weapons, molotovs, pipe bombs, and a medical
cabinet. Yeah... It sucks for the infected at this part. And just as an
added insult to the zombies, it's all inside a small, but easily
navigated room. Hunters cannot score pounces here easily. The only
upside to this location is that a Boomer can try to start a "grind"
here to help alleviate the sheer amount of supplies the survivors just
found. Human mentality tells us that people tend to overuse and
overspend when they feel they have an abundance. Because of this, a
Boomer's vomit attack here may cause the survivors to inadvertently and
absent mindedly throw valuable molotovs or pipe bombs. Considering the
area the survivors must traverse next, this can be potentially lethal
to them.

Outside the building, the survivors get their first glimpse of the
airport. Fearing an ambush, many survivor teams will hesitate and try
to scope out the area before venturing out there. This is one of those
rare occasions where it may be beneficial to spawn behind the team as a
Boomer and make them pay for their hesitation.

It's been called to be patched a lot to no avail yet, but the survivors
can jump over the downed plane right in front of the hole in the wall
the survivors will likely exit the building from. This shortcut skips
the entire section here and puts them on an easy path to pass the
alarmed car without incident. Hunters may want to set up behind the
dumpsters near the alarmed car in case the survivors take this
shortcut. If they don't you should still have enough time to set up
elsewhere to ambush them.

If the survivors do NOT take the shortcut, they must cross the street
and navigate their way past piles of luggage, cars, dumpsters, etc. All
of this cover provides many angles from which a Boomer can attack from,
and provides plenty of movable objects for Tanks to take advantage of
at this point. Hunters are sort of at a disadvantage here because huge
(20+) damage pounces are rather rare, though you can still easily
manage a 12-15 damage pounce with enough of a distraction aiding you.

The survivors will enter a parking structure in order to gain access to
the skywalk, and then finish the level.

*TANK TIP*
Parking structure = many cars = many opportunities to instantly
incapacitate the survivors. A Boomer's horde here can spell death for
the entire team if a Tank can close the gap.

Inside the parking structure, the survivors will head upwards and
eventually reach a stairwell that connects them to the sky walk. The
skywalk is long enough to prevent you from spawning, and the only place
to spawn and make yourself useful is a small room off to the left just
before the safe room.

*SMOKER TIP*
There is a rooftop that overlooks the skywalk. The glass CAN be broken,
but you cannot drag a survivor over the metal railing. It provides you
a last ditch effort opportunity to dish out a little extra damage
before the survivors reach the safe room.

If the survivors make it this far, odds are they'll reach the safe
room. The storage room just before the safe room is your last chance
ambush location. Dish out as much damage as you can here to lower their
health score.


**************************************************************
-------The Terminal------- [L4DAIRd]
**************************************************************

Immediately out of the safe room, the survivors will cross a side path
blocked by rocks. Infected players can spawn behind these rocks in an
attempt to ambush the survivors. Hunters can spawn behind them, and
angle a pounce over the rocks to land on a survivor. Because this is
such a common strategy, many survivor players will hug the left side -
along the railing. You may not be able to reach the survivors if they
stick to the left side.

A little further up ahead, there is a hole in the ceiling which is a
common place for Boomers to try vomiting on the survivors. Many
survivor teams expect this, so it may be in your best interest to NOT
spawn up there. I've also seen plenty of Smoker players try to use that
location, but I don't understand why. Why would anyone want to pull the
survivor team forward?

*BOOMER TIP*
Many players expect a Boomer to spawn in one of two locations. Around
the corner of the side path blocked by rocks, and up above. Instead, a
possible better location may be for you to set up behind the pillar
across from the hole in the ceiling. Survivor players will hear you,
but may start spamming bullets up in to the hole in the ceiling
thinking you're there. If you hear a break in the gunfire, that's your
time to move in. Reload times are always a Boomer's best friend!

*SMOKER TIP*
DO NOT spawn in that hole in the ceiling. I know...it's tempting, but
there are better alternatives! Keep in mind that most survivor teams
fearing an ambush from Hunters as they cross the side path, will stay
alongside the railing to the left. A better location for you may be to
jump down into the wide open area, then climb one of the pillars up to
the top. Run along the top until you are parallel with the safe room
and use your tongue attack from there to drag one of them back.

The survivors will go through a double door and into an office section.
There are plenty of walls here that can be broken, and are great
locations for Boomers to vomit on the survivors. The problem with this
section is that it's a long and narrow hallway. Hordes die rather
quickly. If you plan on vomiting on a survivor as a Boomer here, advise
your teammates to join in as soon as possible because the window of
opportunity can be rather small, especially if all 4 survivors grabbed
Auto-Shotguns at the beginning.

*TANK TIP*
Sometimes, a Tank comes early on this map. The narrow hallways don't
offer much room for the survivors to run...but they also don't allow
you much of a chance to dodge their bullets. A Boomer's horde here can
spell death for the survivor team if a Tank spawns this early in the
map. Odds are the survivors won't have any molotovs and will be forced
to gun you down. There aren't any movable objects you can smash into
the survivors, and you won't be able to get much distance out of your
rock throw ability, so good ol' fashioned boxing is going to have to be
the way you go! Work with your teammates, and tell them what you need
them to do. A good infected ambush here along with a Tank can be all
she wrote for the survivor team.

*HUNTER TIP*
If you're behind the survivors, the narrow hallway can allow you a very
quick method of travel if you're good at wall pouncing. This is one of
those rare occasions where it may actually be beneficial to spawn
behind the survivors. You can pounce at a wall, pounce off the wall,
then pounce off the opposite wall - all while moving forward. Doing
this, you can travel roughly 300% faster than a survivor can run! Plus
it's fun to do! Alternatively, you can try wall pouncing towards a
survivor from the front. Because you're constantly changing direction,
it may be difficult for the survivor to target you before you land your
pounce.

The survivors, after traversing the first narrow hallway will make a
left turn and head down another long narrow hallway. The same Hunter
strategy applies here. If you're proficient with wall pouncing, you can
actually round the corner without ever touching the ground! It requires
a bit of dexterity on your part, but it's possible to do, and it's like
riding a bike. Once you learn how, you'll never forget.

The survivors will go through another double door to reach the
crescendo event room. It's a wide open area where 20+ damage pounces
can be attained by Hunters. The survivors need to start up the van in
the area to crash through a barricade. This will start the event. You
must be ready to act both before, and after they start the event.

*HUNTER TIP*
You can climb above the landing the survivors enter the room on. As the
survivors go down the escalator, get ready to act. It can be difficult
gauging when you need to pounce to snag a survivor who is running away
from you, but with some practice, you can land some monsters here.

*BOOMER TIP*
Everybody and their mother expects a Boomer to be up above, waiting to
vomit on the survivors down below. Instead, this is one of those rare
occasions where a Boomer can be more effective spawning behind the
survivors.

The crescendo event can be rushed past by the survivors, and many teams
opt to handle the situation this way. ALWAYS expect them to use this
strategy, because then you'll be ahead of them to set up an ambush. If
the survivors decide to camp out in one of the side rooms just past the
gate that was destroyed, you can move in and try to get some claw
swipes on the survivors. This is a 2 wave horde - and it's rather
large, so if the survivors decide not to rush it, they'll be here for a
while.

If the survivors DO decide to rush it...a Boomer up ahead can stop them
long enough for Hunters and the Smoker to move in and try to cause even
more of a disruption. The zombies from the event will swarm in from the
opposite side of the fence in the wide open room - but they don't
disappear just because the survivors rushed through. Holding up the
survivors in the baggage handling area may allow the previous horde to
catch up and complicate things.

*TANK TIP*
Sometimes a Tank will spawn as the survivors reach the terminal.
Because Tanks usually spawn a good distance ahead of the survivors, the
gate will be blocking you from charging at them. Truth be told, I've
yet to find a good round about path to attack the survivors from that's
time-efficient, and unpredictable. You *can* crouch over the fence to
gain access to the wide open room, but usually the survivors will be
taking pot shots at you while you crawl about as fast as a paraplegic
baby. You will *need* your infected teammates to stall the survivors
while you make your way over the fence and into the terminal. Once in
the terminal, the survivors will likely backtrack into the hallways. A
Boomer's horde here can slow them down greatly, and if you can land a
punch on one of the survivors, odds are they won't fly far, allowing
you to punch them again.

Past the event, the survivors will enter the baggage processing area.
There are a lot of ups and downs here, though the path is pretty
straightforward. Smokers have the opportunity of dragging a survivor
down after they go up the first staircase. A Boomer working in
conjunction with that Smoker can severely slow the team down. Hunters
may find it a little easier to run up - take a swipe - then run away
amidst the chaos.

There are a few rooms off to the side in the baggage processing room
that can contain goodies for the survivors. A lot of survivor teams
will neglect to check these rooms, but if they enter one of these side
rooms, a Boomer can try to start a "grind" cycle with them.

Past the baggage room, the survivors will enter the airport security
checkpoint room. There is a metal detector that will alarm if a
survivor runs through it.

*SMOKER TIP*
It's difficult to do, but if you can pull somebody back through the
metal detector, the survivor will activate it and draw a horde.

*TANK TIP*
The statue holding the globe can be destroyed and the globe itself can
be used to instantly incap a survivor. Due to a bit of a glitch if you
want to call it that...the globe still rolling even a tiny bit can
incap a survivor that comes into contact with it. If you can hit the
globe and then try to herd the survivors into it. If you're lucky, you
won't even need to hit the globe again, the survivors will do the work
for you!

Past the security checkpoint, the survivors will head up an escalator
and then finally see the runway. The safe room is a ways down this area
on the right side. There's plenty of cover for Boomers and Smokers to
hide behind before spawning, and Hunters can also take advantage of the
many obstacles slowing the survivors down by simply pouncing over them.
Unless the survivors are really hurting by this point, odds are they'll
make it to the safe room without much more hassle. Just try to get
whatever damage you can out of the time you have left.


**************************************************************
-------Runway Finale------- [L4DAIRe]
**************************************************************

The Dead Air finale doesn't have a long path leading up to the trigger
that starts the event. Rather, it's one HUGE wide open area dotted with
objects that can allow Smokers and Boomers to hide and spawn behind.

*BOOMER TIP*
Run to the end of the ramp and climb up the pillar after dropping down
to the left. You can get up top and walk along the wall to get directly
above the survivors. As they leave the safe room, you can vomit on them
as they run out. This should keep the survivor team on the ramp, and
while the horde drawn by the vomit attack may not accomplish anything,
your teammates can take advantage of the slowdown.

*HUNTER TIP*
Follow the same strategy for setting up in the Boomer Tip. From up
there, you can arc a pounce and land on a survivor as they run out of
the safe room. Expect a pounce anywhere from 10-16 damage from this
location.

*SMOKER TIP*
There is a hill off to the left after dropping down off the ramp. It's
a fairly common place for Smokers to spawn, but it allows you a bit of
cover should your tongue be broken. There is a broken section at the
end of the ramp that you can use to try pulling one of the survivors
down. If the survivors got vomited on earlier, this can cause some
extra damage. If you dragged someone who was vomited on, the horde will
go after your victim. If you dragged someone who wasn't vomited on,
his/her teammates may be slow in coming to the rescue.

The finale map is very large. Truth be told, the survivors typically
only explore roughly 40-45% of it during the duration of the time they
spend here. There are goodies scattered against the airport building's
walls but survivor teams hardly ever check over there. The main supply
stockpile is near the fuel truck that's needed to start the event. Even
so, the most common place for the survivors to camp out is against the
yellow tape way out in the open.

*HUNTER TIP*
The survivors must put themselves in big pounce territory in order to
start the event. There are two good places in which to get 15+ damage
pounces. The first location is on top of the plane. Arc a pounce over
the wing if needs be, and a 15-17 damage pounce is likely. The second
location is atop another broken lamp to the left of the mounted machine
gun. You can achieve 20+ damage pounces from here, though you leave
yourself more exposed while setting up.

*BOOMER TIP*
This finale event is a Boomer's nightmare. If you are a Boomer and you
have the chance to choose where to spawn (the event hasn't started yet)
save your spawn until the first Tank comes in the event. Boomers are
too fragile, too easily spotted, too slow, and too valuable during this
event to waste.

The finale events always follow a set pattern.
1) Horde
2) Tank
3) Horde
4) Tank
5) Last ditch effort Horde + Tank

*TANK TIP*
There are plenty of movable containers that you can smash into the
survivors. The problem with this is that because it's such a wide open
area, the survivors will probably spread out and try shredding you down
at long range. This is why saving the Boomer spawn is so important.

*BOOMER TIP*
If you or one of your teammates saved the Boomer spawn, a horde
surrounding a survivor here can spell an instant incap as it allows the
Tank to take a shot at a stationary target. I know that it's more fun
to get in on the action...but you know the saying "Good things come to
those who wait." What you need to do is spawn behind some cover and
then quickly vomit on at least one of them. The horde will swarm in,
and the Tank on your team will have a MUCH easier time destroying the
survivors.

After the first Tank, the survivors may head back to the supplies to
restock on ammo and/or change guns, not to mention grab a few health
packs if needs be. Hunters need to get ready to score big pounces
during this short opportunity, the Smoker needs to be ready to snag a
straggler, and a Boomer now has some extra cover to spawn behind and
try to delay them from getting back to their camping spot.

It's common for at least one of the survivors to grab a Hunting Rifle
on this finale, and for good reason. It's a very wide open map with
nothing to hide behind out in the open. As a minor distraction, Hunters
can try pouncing in long arcs across their field of vision at long
range. It may distract the team long enough for a Smoker to get a good
pull and cause some extra damage.

Molotovs are rather rare on this map from what I've noticed. If the
survivors found one, that's pretty generous from the AI Director. That
being said, if they used a molotov against the first Tank, odds are
they won't have another one for the 2nd.

After the 2nd Tank, the plane will start up and the back hatch will
open to allow the survivors on. This takes a little longer than you may
think, and it may give your last ditch effort Tank a chance to pummel
the survivors away from the plane resulting in a huge loss of points.
Remember, if a teammate is incapicitated while the others are on the
rescue vehicle, the map ends, and they lose a survivor multiplier
greatly reducing their point total.


**************************************************************
-------Blood Harvest Overview------- [L4DHARVEST]
**************************************************************

Blood Harvest from what I've seen in my online experiences is the
outright LEAST played campaign in Left 4 Dead's VS mode. There have
been many times where I tried to join a Blood Harvest game in progress
or in lobby, only to have it create a lobby with me as the leader...

I remember seeing a chart with the following information, but I can't
for the life of me remember where I saw it. If it was your website that
had this information, then kudos to you for coming up with these
numbers!
Percentage of VS matches played per map:

No Mercy - 36%
Death Toll - 20%
Dead Air - 38%
Blood Harvest - 6%

Yeah...

Blood Harvest takes place in the afternoon on an overcast day in a
rural area. Because of this, Hunters put out a very noticable
silhouette against the sky, however Blood Harvest still offers many
locations where 25 damage pounces can be achieved from. The maps are
actually quite expansive, with more areas for the survivors to go than
expected off the beaten path, but in spite of it's size, it actually
feels a bit claustrophobic in many of the outdoor areas and the
survivors will stick to the main path most of the time.

Blood Harvest has tons of thick foliage for Smokers to hide behind and
offset their visual cue - especially on the first map. Though you
should keep in mind that the thick leaves and branches only block a
survivor from seeing you. Technically they are still alert to your
presence because you're "out in the open." You will need to find
additional cover in order to spawn and attack. The thick foliage also
helps Boomers and Hunters use the element of surprise to perform quick,
unexpected attacks.

The Blood Harvest campaign has only 2 major crescendo events, both of
which can be rushed past. This can really hamper the infected team's
chances of dishing out damage should the survivors decide to try and
power through the events. Perhaps this is why the campaign seems so
unpopular.

Blood Harvest is arguably the shortest campaign, and therefore the most
survivor-friendly. It doesn't have more than a couple of choke points
throughout the entire campaign, and on most of the maps, it can be
difficult to separate the survivors. The campaign isn't necessarily bad
for the infected team, though. There ARE locations to disrupt and
disorientate the survivors. There ARE locations to attack unexpectedly
from. It's just that they may be a bit more difficult to point out.
That's where this guide comes in!

Unlike No Mercy, Death Toll, and Dead Air, there aren't many obvious
areas where the VS mode differs from the campaign mode. The farmhouse
in the finale map doesn't have some small rooms off to the side and
some more walls can be broken upstairs, but aside from that, it's
largely unchanged from the normal campaign.

Blood Harvest isn't really a dark campaign - it just seems that way.
Indoor areas can be rather dark, but all of the outdoor areas are
actually pretty well illuminated. The inability for the survivors to
see what's coming at them adds to a creepiness factor - but you should
still never assume that the survivor team will make mistakes just
because of the environments' appearance.


**************************************************************
-------The Woods------- [L4DHARVESTa]
**************************************************************

Starting off, the survivors will walk down a trail with a thick tree
line on both sides. Most infected players will set up on the right as
it offers more room to move around in. There is a hill that Hunters can
use to pounce from for some additional damage, and a Boomer's horde
here can potentially cause some major damage to the survivor team as
the blinding effect combined with the trees and bushes can drastically
slow a survivor's reaction time - not being able to act until the
zombies are literally right in their face!

*BOOMER TIP*
If you don't die after vomiting on the survivors in the very beginning
of this map, it may be wise to wait until the survivors are no longer
blinded (as indicated by their silhouettes changing back to green,
yellow, or red) and then simply running into the fray and hopefully
blowing up all over them. This can help to keep the pressure on the
team - and since a spawning time is generally shorter than the recharge
time on the vomit attack, it can be beneficial. Another benefit to
simply going kamikaze on this map is because in the beginning, the
survivors may have a difficult time seeing you until you're pretty much
in their faces!

*SMOKER TIP*
The thick brush here can be helpful in psyching out particularly
curious survivor players. Since the Smoker's tongue attack makes a
distinct noise that the survivors can hear, if you intentionally miss
with your tongue attack, one of the survivors may come your way in an
effort to kill you. Drop down the cliff, and if one of them peeks over,
try dragging them down. I believe it was patched dragging them to their
deaths - they'll just hang onto the side of the cliff now, but even if
you only get the instant incap, it allows your other teammates a great
opportunity to attack. Boomers especially.

Following the path, the survivors will reach a picnic table that may
contain goodies, and there are often molotovs or pipe bombs on the
ground nearby. The survivors will have to cross a narrow bridge over a
ravine and will come upon a house that usually contains some goodies
and an ammo stockpile.

*HUNTER TIP*
I'm not sure why this works...but there is a steep cliff to the right
after crossing the bridge. You can get behind it, then either pounce up
to the top, or crouch and crawl up. There are actually a surprising
number of places where a Hunter can crawl up a cliffside without
actually "climbing" it. From atop that cliff, you can land big pounces
on the survivors as they cross the bridge. Or, from atop that cliff,
you can try pouncing onto the nearby telephone pole. From the top of
that, you can land a pounce all the way to the house's door and window
for big damage.

*TANK TIP*
The car parked outside the house can NOT be used to smash into the
survivors. Don't bother. There are no movable objects on this map to my
knowledge. If a Tank spawns before the survivors reach the bridge, it
may be wise to try and hang back and toss rocks at them while you wait
for a Boomer on your team to respawn and try distracting them.

Just outside of the house, near the picnic table, pipe bombs and
molotovs commonly appear. Monitor which survivors are carrying what
items so that you can formulate a more effective attack plan.

*WITCH TIP*
It doesn't always happen, but for some reason, I have noticed a Witch
spawning near the small shack VERY often as the survivors just leave
the house past the bridge. Beware of molotovs here, and in spite of the
location, having the Hunters crouch in front of her actually isn't the
best strategy here. There are numerous locations for Hunters to land
big pounces as the survivors make their way past the witch - or try to
cr0wn her. Boomers can spawn behind the shack and try to get a quick
vomit attack off that may add to the chaos, and of course, Smokers can
do their part to separate the team. If the survivors look as though
they may try to "pull" the Witch, this is one of those extremely rare
areas where a Smoker may want to spawn in front of the survivor.
Pulling the Witch generally results in the rest of the team
backtracking. You just want to create as much distance between the
survivors as you can. If you're a Smoker, you may be able to get
additional damage off by dragging one of the survivors forward while
the rest of the team deals with the more immediate threat.

Down the path, the survivors will reach a small shack that may or may
not contain pills or a med pack. Most survivor teams will just skip it
as the map is rather short and they're pretty close to the safe room.
All along this stretch, the survivors are very vulnerable to huge
pounces from Hunters, the terrain allows for maximum backtracking by
Smokers, and Boomers still have adequate foliage cover to hide behind.

*HUNTER TIP*
From the top of the section of the building that spans over the path
below, you can land huge pounces as the survivors first enter this
"valley." For some additional range at the expense of noticeability,
you can pounce to the top of the telephone pole. If a Witch is nearby,
this is a great place to perch atop as their attention will most likely
be on the Witch and any ambush close by. You can also pounce onto some
of the thicker trees - but be warned that only SOME of the branches
from your perch can be passed through. It may affect the trajectory of
your pounce. The benefit of these locations is additional cover. You're
less noticeable. Just be sure you'll be able to act effectively when
you need to.

The survivors will make a left turn and head into the home stretch of </pre><pre id="faqspan-6">
the map. Hunters and Boomers can attack from. Smokers will obviously
want to drag the survivors back. There is room off to the right of the
path (facing the safe room) that any infected can take advantage of,
however. The problem is, it's difficult for Boomers to attack from as
the survivors will likely be hugging the wall on the left. Hunters can
try pouncing from the right side, and the angle may be better, but
don't expect any big damage pounces anymore from this map.

If the survivors make it to the "home stretch" of the map in decent
health, odds are they'll make it to the safe room with decent health.
Just do what you can to lower their health score. Co-ordinated attacks
usually take a little time to plan, and if the survivors are this close
already, odds are attacking solo will generally dish out more damage
than a quick plan will.


**************************************************************
-------The Tunnel------- [L4DHARVESTb]
**************************************************************

From the beginning of the map, the survivors can go either left or
right. In order to progress, they must head right, but many survivor
teams will check to the left for goodies or a 2nd pistol before
venturing forth. They'll run down a staircase and enter a hallway with
two rooms branching off to the left that continue their route. Either
one of these rooms may contain tier 2 weapons for the survivors.

*BOOMER TIP*
In the hallway, the first room off to the left has a smaller room off
to the side with a stack of boxes in it. You can use this as a decent
ambush location. OR, if every survivor crams into one of the rooms, the
wall between the two is breakable, so you can also use that to your
advantage.

*SMOKER TIP*
If the survivors enter the first room on their left after entering the
hallway, odds are they'll exit through the windows onto the catwalk.
There is no railing there, and Smokers can drag survivors off of it
causing falling damage.

After finding their way down to the lower level, the survivors will
approach an emergency door. The table just outside of that room is a
common place for tier 2 weapons, and the small room with the emergency
door contains a medical cabinet stocked with either pills, med packs,
or both.

*TANK TIP*
If a Tank spawns here, it will most likely be on the other side of the
emergency door. Tanks cannot break it down. In order to get at the
survivors, go up the nearby staircase and enter the vent. You can drop
down in the emergency door room to attack the survivors. There is a
forklift you can use to try and smash into the survivors here as well.

Upon opening the door, an alarm will sound and the crescendo event will
start. There are 3 common survivor team strategies employed here.

1) Rush it. Open the door and haul ass towards the exit, fighting
through the ensuing horde. If you see the survivors employing this
strategy, you can try to take advantage of the chaos. Boomers here are
especially helpful as the blinding effect hinders direction, and it
ANOTHER horde will be summoned on top of the event's horde.

2) Stay in the room with the emergency door. The survivors will just
dig in and weather the storm without moving about. This is a much safer
strategy than rushing it as the infected have only 2 doorways from
which to enter the room, and a vent to drop down from. All 3 entrances
can be easily covered by the survivors. Hunters may find it more
beneficial to try and blend in with the hordes that enter the room and
try to get a melee swipe or two off. After the event and the survivors
begin to move on, Boomers can try to keep them in that room and start a
"grind" cycle with them to potentially dish out more damage.

3) Go through the door, head up the staircase, and camp out in the room
with the vent. This is generally the safest strategy for survivor
teams. Now, the infected only 1 direction from which to attack the
survivors. From the staircase. I haven't seen infected climbing through
the vent. There is, however, a small room blocked off by a door off to
the side that from what I've noticed, many survivor teams simply
ignore! Break the door and try taking melee swipes at the survivors.
Good survivor teams will probably send someone to cover that side room,
and therefore block you from spawning. This can be very frustrating for
the infected team as there is really nothing you can do about it, and
no good way to attack. You can *try* running in and taking a quick
swipe at the survivors, but because the room is narrow and long with
only 1 viable entrance, you probably won't get to dish out any damage.
Best to just set up for an ambush after the survivors move on if they
use this strategy.

After the event, the survivors can either head upstairs onto a balcony
to exit through the large windows or stay on the ground level and exit
the building through a doorway. Regardless of which exit they take,
there are several great places for Hunters to set up for huge pounces
here. Outside, there is a table that is a common place for tier 2
weapons.

*HUNTER TIP*
Great locations for 25 damage pounces are all over the place here. You
can make it to the top of the building, and even on top of a pipe
overlooking the table that may contain tier 2 weapons for the
survivors. If they exit through the windows up top, you have a much
better chance at landing a big pounce - simply because they leave
themselves in an open area for longer. But either way, most survivor
teams will stop by that table for at least a short time, allowing you
to try and land a monster pounce! You may also want to try above the
tunnel the survivors will be entering. This is a great ambush location
for when the survivors look like they'll start advancing.

*SMOKER TIP*
Because huge pounces here are so common from Hunters, if you're a
Smoker, alert your team that you'll try dragging a survivor out into
the open. There isn't much a Smoker can do here damage-wise anyway, so
a co-ordinated attack between you pulling a survivor into an area with
a clear line of sight to a Hunter on your team can result in massive
damage to one of the survivors, OR...if a rescuing survivor comes to
their teammate, it can result in two of them (though probably only
briefly) being rendered helpless.

Upon entering the tunnel, the survivors will bob and weave their ways
around train cars. There are several sections here where they can
choose to head left or right. The right paths are generally less
crowded with zombies, and most teams prefer to take those for that
reason. The first choice to go right brings the survivors atop a train
car. Smokers can try dragging the last survivor up top back and force
his/her teammates to backtrack to rescue the ensnared victim. This can
be a great setup to a very damaging ambush. If a Smoker pulls a victim
back, alert your teammates to pounce or vomit on any other survivor
coming to the rescue.

*TANK TIP*
There are no movable objects here. On the plus side, the area is rather
enclosed for you, and if a Boomer on your team can vomit on one or more
of the survivors, they'll likely be slowed down long enough for you to
catch up and start wailing on them!

Through the tunnel, most survivor teams will continue straight forward
and climb a ladder on the side of an oil tanker. This can be used as a
good choke point for Hunters and Boomers. Survivor teams can, however,
walk along the pipes to the left and cross that stretch without having
to take the ladder. Smokers here, though can be great to separate the
team for a Boomer to get a good shot at causing some chaos.

Past the oil tanker, the safe room is just around the corner. If the
survivors make it here in good health, odds are they'll just waltz
right into the safe room. Do what you can to lower their health score,
but all probability says they'll make it no problem.


**************************************************************
-------The Bridge------- [L4DHARVESTc]
**************************************************************

The survivors start out with a decision to make. Left or right.
Regardless of which path they take initially, the ambush location is
always the same. The room in the middle of this tunnel. I'd say that
99% of survivor teams check this room for goodies, and this is where
you can start some havoc.

*BOOMER TIP*
*HUNTER TIP*
*SMOKER TIP*
No matter which way the survivors start off, they'll more than likely
head into the room between the two paths. They *have* to go left to
proceed, but this room is more often than not stocked with goodies. A
Boomer here to force a horde on the survivors is a great way to get the
Smoker to drag one away while the Hunters go after anyone who looks
particularly vulnerable. You can dish out more damage here than you'd
expect with a co-ordinated attack. Just make sure that if you're a
Boomer, you don't spawn until you're ready to attack. Survivors expect
this, and therefore you should try to be at least a little
unpredictable.

The survivors will eventually come to the exit of the tunnel they're in
and because it's a wide open area, a lot of survivor teams hesitate to
just burst out into the open fearing Hunter pounces... Don't worry,
those are coming later! In spite of survivor hesitation, Boomers should
NOT spawn behind the team. Odds are the survivors will be close to the
exit of the tunnel, and spawning behind the survivors will result in
the Boomer having to make a longer than desired run towards the
survivors from around the corner and risk being detonated at a safe
distance.

*BOOMER TIP*
Instead, spawn in front of the survivors just outside the tunnel, and
try to puke on a few of them immediately after spawning and running in
front of them. You'll likely die, but now you may be able to start a
"grind" with your teammates. Going in and dishing out damage, dying,
and then by that time you may have a chance to respawn and start the
process over again.

The survivors expect big pounces as they exit the tunnel. This open
area is very likely to see a pounce over 20 damage. Some survivor teams
will try sticking to the left wall leaving them vulnerable from the
right. Some survivor teams will try sticking to the right wall leaving
them vulnerable from the left. And some survivor teams will just run
straight up the middle making them prime targets from both directions!
And no matter which way the survivors intend to run, they're ALWAYS
vulnerable from the rear.

*HUNTER TIP*
From the rear, you can pounce up and over the fence just above the exit
from the tunnel. With the right timing and aim, you can manage a 15+
damage pounce. Also note the trees and the rocks behind and to the left
of the tunnel's exit. These can provide great perches for Hunters to
make huge pounces from. If you set up on the rocks, however, make sure
to aim a bit more to the right than you might want. Otherwise, you
stand a good chance at pouncing into an invisible wall and really
messing up the trajectory of your pounce. Hunters can also set up on
the hill to the right just outside the tunnel. As with any big pounce
opportunity, aiming and timing is important, but with enough practice,
you can start consistently managing large pounces in this area. If the
survivors decide to run up the middle, they're the most vulnerable.

*TANK TIP*
If a Tank spawns as the survivors are leaving the tunnel, you can make
use of a large log outside. The common survivor strategy here when a
Tank shows up is to actually run back into the tunnel and try to deal
with you there. Instead, you can use that big log to temporarily trap
the survivors in the tunnel and allow your teammates who haven't
spawned to go in for cheap quick attacks. You'll eventually lose
control of the Tank if you trap the survivors back in the tunnel, but
if the log disappears after you give control of the Tank to another
teammate, think of all the extra cheap damage you got out of this
opportunity!

Outside of the tunnel, the survivors will follow a linear path around
the cliff to their right and up a slope leading to the top of it. After
moving up the slope, there is a large tree at the top of the hill that
may have a med pack behind it. The survivors can now either enter the
building in front of them, or head off to their right to check a
camping site for weapons, pills, med packs, or other goodies. Even
further past the campsite, along the rocks past the fence there may be
another med pack or pills pickup for the survivors.

*SMOKER TIP*
If the survivor team decides to check out the far area past the fence
and one of them ventures a little too close to the ledge, you can drag
one of the back down and force him/her to remake the trip around the
cliff again. After making that drag, you'll likely be promptly killed.
If no other teammate drops down as well to escort, a Hunter on your
team can dish out amazing damage as that survivor makes his/her way
back up the path.

Inside the building, the survivors may find molotovs, pills, and/or
pipe bombs. They must descend a large zig-zag staircase and enter a
hallway. There is a table here that may contain tier 2 weapons. They'll
go through a doorway and have the option of simply pushing forward or
checking 2 rooms off to the right. Most teams do, as these side rooms
more often than not are stocked full of goodies of all sorts.

*TANK TIP*
If a Tank spawns here, beware of simply charging into that narrow
hallway, as tempting as it may be. Right by the doors, there are
usually propane tanks or gas cans that will stagger you - meaning free
shots the survivors can take and really tear you to shreds while you
recover, OR, being lit on fire with no way to put it out. Wait for at
least a Boomer's attack before charging in. Hunters and Smokers may be
able to create a short distraction, but a Boomer is the most valuable
teammate here as hordes may block them as they try to backtrack.

Outside this building, the survivors will be near several train cars.
Just outside the door is a common place for gas cans, propane tanks,
and a table that may contain tier 2 weapons. After exiting the tunnel,
the survivors will enter a wide open area, though train cars for the
most part force the survivors to take a straight path. There is a large
metal shack the survivors will more than likely check that will contain
an ammo stockpile, and is a common place for molotov and pipe bomb
pickups.

*HUNTER TIP*
See that really tall tower off in the distance? You can make it to the
top of it, you know. It's true! If you're proficient at doing wall
pounces straight up, you can use this perch for amazing distance and
guaranteed 25 damage pounces should you land one. You're going to want
to wall pounce up the side with the ladder (Not sure why you can't just
pounce up and CLIMB it...). Hold back the entire time ("s" key by
default), aim straight up, and pounce. While in midair and still
holding back, tilt forward about 10 degrees or so and wall pounce. Keep
it up until after you make 4 to 5 straight up wall pounces. You should
be on the landing just below the cone on top of the tower. From here,
you can pounce up to the top of the cone and voila! Your perch. The
haze on this stage can actually make you pretty tough to pick out,
though you may still want to stay crouched on the back side of the cone
just to make sure you don't get picked off. From up here, you can
pounce all the way to the large metal shack, and you can pounce over
the bridge and land at the door to the small house in the middle of
this area. Land a pounce here and you're more than likely going to get
something in the 25 damage range...

The survivors will more than likely check out the small house in the
middle of this map. It has an ammo stockpile, tier 2 weapons, and a
medical cabinet. They'll have to leave that house eventually in order
to start a crescendo event and make their way to the nearby safe room,
however, Boomers can start a "grind" here.

*BOOMER TIP*
Do whatever you can to keep the survivors in that house. There are
numerous entrances you can use. Windows in the front, and there are 2
doors you can enter through. If you live after you vomit on them, wait
for their silhouettes to turn back to green, yellow, or red, then waltz
on in and try to blow up on them. It'll summon another horde and give
your teammates who should go in and try to score quick pounces or claw
swipes a good chance to respawn before the survivors start the event.

After making their pit stop in the house, the survivors will need to
start a crescendo event that involves destroying a bridge and giving
them a path up the cliff. This event can be skipped, and is commonly
done so, with most teams tossing a molotov at the base of the bridge
and having their survivor teammates simply run through the fire. A
Smoker here to drag one of them back can be extremely helpful as it
leaves the survivor and any other rescuing teammate out in the wide
open with a horde on them. Remember, Hunters love stationary targets...

Past the bridge, the survivors will enter into the home stretch of the
map. There aren't too many good places to spawn here, but there is some
thick foliage for Boomers and Smokers to hide behind in case they
spawned earlier. Hunters can perch up in the large tree just outside
the safe room, and Boomers can spawn behind the tree as the survivors
make their way to the finish line. It provides a last-ditch effort
ambush, and that's probably all you'll get before the survivors make it
to the end of this map.


**************************************************************
-------The Train Station------- [L4DHARVESTd]
**************************************************************

Most teams employ a rushing strategy for this entire map, believe it or
not. Tier 2 weapons are available from the start, there's no crescendo
event, the actual length of the map is surprisingly short, and it
contains a lengthy home stretch at the end that blocks infected players
from spawning. If you're going to stop the survivor team on this map,
you have to do it before they reach the 2 story house near the end
because after that, it's smooth sailing down a long train bridge with
no cover to spawn behind other than on top of the train car they'll use
as their safe room and end the level in.

There's a pretty thick tree line here in the beginning for Boomers and
Smokers to take advantage of to the right out of the safe room, but
beware of survivor teams hugging the right side in an attempt to save
some time. It's not really common for survivor teams to employ this
strategy right out of the chute, as the thick brush will hinder their
vision. It *is* a safer route, but most players would prefer a little
more danger instead of hindering their vision. That being said, most
survivor teams like to stay right in the middle.

*HUNTER TIP*
For whatever reason, Hunters can crawl up the steep cliff just to the
right out of the safe room. You can jump over the fence alongside it
and then crawl up the back side. From up here, you have a few trees you
must avoid when trying for a big pounce, but a successful one here will
net you over 18 damage easily.

*BOOMER TIP*
The thick treeline here offers adequate cover to attack from once you
spawn. The problem is, spawning while still technically "in view" of
the survivors. You can use the trees to try and spawn in, or you can
try spawning behind the boulder near the barn at the end of the initial
path.

The survivors may do one of two things as they approach the barn.
1) Check it for supplies. This, I think is kind of a waste in my
personal opinion unless there was a nasty infected ambush at the very
beginning of the map. Molotovs and pipe bombs CAN spawn in the barn,
but more often than not, all the survivors will get is a gas can or a
propane tank. There may be a 2nd pistol as well...but seeing as how
tier 2 weapons are available at the start of the map, odds are they'll
just be sticking to those weapons instead. Coming into the barn,
however, keeps the survivors in the field of play a little longer, and
may provide Hunters with some extra time to get into big pounce
territory as they leave. A Boomer successful in vomiting on the
survivors as they approach the barn may cause the survivors to huddle
up inside and wait until the horde has been finished off.

2) Skip it. Remember, this is a rush map, and you have to be sure you
can keep up with the survivors should they haul ass the entire time. If
the survivors look as though they're going to skip past the barn, there
is a particularly nasty tactic that can be used against hasty teams
that I'll detail later.

*HUNTER TIP*
As the survivors leave their shelter, most everyone expects a huge
pounce from a Hunter coming from off the barn. But did you notice those
silos past the barn? They're in the infected field of play, and Hunters
using wall jumps can reach the tops of them. I find it the easiest to
actually run behind the silos and try wall pouncing upwards from there.
And you won't get shot at, either. A successful pounce from here that
gets less than 20 damage on contact is embarrassing.

*SMOKER TIP*
So the survivors look like they're rushing it, huh? There's a ledge
they must jump down. This is your cue to try and pull the last survivor
back. If the other 3 have descended to the ground below and aren't
still on the white awning, it'll take more time than they're
comfortable spending to go and rescue their teammate. Survivors CAN get
back up to where you pulled the survivor, but something like this may
alter the team's mentality of rushing through the map, and that can be
good as they'll likely be more cautious, slow down, and stay in the
game longer for you and your teammates. And, a successful Smoker pull
here can drag a survivor back into range for a huge Hunter pounce from
the top of the silos as listed in the previous Hunter Tip.

*TANK TIP*
There is a large log you can use to bash into the survivors close to
the ledge past the barn. This is a rather wide open area, so a Boomer
here to assist you is your greatest ally.

After descending, there are a few ways the survivors can go. They can
enter the large building and check for supplies. Odds are they'll find
pipe bombs or molotovs here. Out the front entrance of the building is
an alarmed car that Smokers can try to pull survivors into and summon a
horde.

The survivors can decide stay outside and run to the right side of the
train cars - there is a small house here as well that may contain
supplies. It always contains an ammo stockpile as well. Hunters can
land decent pounces from atop the train cars as the survivors make
their way to the 2 story house.

Or the survivors can decide to stay outside and run to the left side of
the train cars. This is the most straightforward path, but is empty on
the supplies, and it allows for Hunters to make big pounces from behind
the survivors.

*TANK TIP*
This is a rather wide open area, and while the only movable object you
have at your disposal is the alarmed car, know that the landscape
slopes downward pretty sharp and there's only a low fence as a railing
to a cliff. If you can manage to get beside a survivor who may be
trapped by a horde, or slowed down enough by a few common infected
hits, you can punch a survivor from the train tracks down that slope
and skip them off the fence and down the cliff for a home run! Remember
that common infected will block a survivor's path, so it may not work
if a zombie is standing where you want to hit the survivor...and the
trees down below may block the survivor from sailing off into the wild
blue yonder, but either way, if you can attack here, expect to get some
decent damage out of the Tank spawn. With sufficient support from
infected teammates, this section of the map can be treacherous.

The survivors will approach a 2 story house and there are 2 ways they
can go about this obstacle. The first is the most straightforward. Go
through the house! Up the stairs and out the window. The other way is
to actually jump over the fence to the right of the entrance door and
follow a path behind the house along the cliffside and under the bridge
before emerging on the other side.

*SMOKER TIP*
If the survivors are taking the house route, try to drag a straggling
survivor. If the team wants to help their ensnared friend, they may
have to jump over the pile of rubble, re-enter the house, and then deal
with you. This can cause a substantial amount of damage if you can pull
it off. And if the survivor team decides to hop the fence and take the
roundabout way along the cliffside, again, you can try dragging the
last survivor back. This will force the others to either abandon their
teammate, or run around the path, jump over the pile of rubble, then
kill you which can result in some pretty hefty damage.

*TANK TIP*
If the survivors think they can juke you by taking the roundabout path
behind the house, meet them there! There's no railing to help them if
they get punched. Home run!

Upon exiting the house or coming up the hill from the back path, the
survivors enter the dreaded home stretch of this map. It's extremely
frustrating for the infected team. It's wide open with NO cover at all
to hide behind other than on top of the train car that'll be used for
their safe room. Hunters can try to play catch up by pounce up above on
the bridge and making headway towards the survivors, but odds are
you'll be shot down shortly after pouncing on a victim...if you even
get that far. Smokers have no hope here, and Boomers are completely out
of the question. You can *try* to go in for some extra damage, but even
if the survivors are all limping towards the safe room, odds are
they'll make it - that's how broken this area of the map is,
unfortunately.

Do what you can to lower their score, but don't expect much once they
reach the train bridge.


**************************************************************
-------Farmhouse Finale------- [L4DHARVESTe]
**************************************************************

Blood Harvest's finale map is rather interesting. It's the biggest
finale map in the game, believe it or not, and has several obstacles
the survivors must navigate both physical and visual-only. Along the
path towards the farmhouse, Hunters can manage big pounces, and right
from the get-go, there is a kinda-sorta glitchy instant kill spot for
Smokers to take advantage of.

*SMOKER TIP*
After leaving the safe room, head to your left and stand just behind
the rocks on the edge of the cliff. If you can manage to pull someone
back here, you run a very good chance of pulling them over the edge and
since survivors cannot hang onto the rocks, they'll plummet to their
death. Doesn't always work and it's been called to be patched to no
avail as of yet, but it's beautiful for the infected team when it
works.

*HUNTER TIP*
You can crawl (or pounce) up the steep cliffside along the left side of
the path. Landing big pounces here is pretty common, just make sure
that a Boomer is able to vomit on at least one of the survivors.
Getting to the farmhouse is the biggest priority, and there are no side
rooms for survivors to check along the way, so odds are they'll be
moving quickly.

As the survivors leave the safe room, expect them to immediately turn
around and spam bullets above the train car, to the left in the bushes
and to the right on the rocks. Getting an effective infected ambush
here off is difficult, but if you co-ordinate it right, you can cause
some serious havoc amongst the survivor team.

As the survivors make their way forward, they'll eventually reach a
train car with a ladder on the side they must climb up. This is a good
choke point and possible "grind" location for Boomers to take advantage
of. While it is a pretty wide open area, repeatedly pulling survivors
down off the ladder can keep them here and whittle them down little by
little. Also remember that Boomers that blow up in close proximity to
survivors stagger them back...possibly off the train car forcing them
to reclimb the ladder. Hunters can achieve that knockback effect by
pouncing on a survivor with another survivor standing close by. With a
horde blocking the ladder, this can open up a great opportunity for
extra damage.

Up the ladder, the survivors will continue on their path that will wind
around to the left. I haven't been able to find a good perch for
Hunters to take advantage of here, but you can use the cliffsides (as
far up as you can go) to get some extra distance and damage out of your
pounces. There is an amazing opportunity here for Smokers to take
advantage of, though it can be extremely difficult to pull off
successfully.

*SMOKER TIP*
Once the survivors jump down into the corn field, there's no coming
back. Which means if you can manage to pull the last straggling
survivor back after the other 3 have descended, it results in a
guaranteed kill for you! Good luck!

Next, the survivors will jump down a short cliff and into a large corn
field. Hunters and take great advantage of the visual cover provided
for them, and Smokers may be able to get extra damage should a Boomer
connect with his vomit attack. Spawning in this area can be rather
difficult since there is very little "physical" cover, but if you CAN
spawn, take advantage of the survivors' hampered situation.

*BOOMER TIP*
In spite of the visual cover you have in the corn field, technically
you can still "be seen" by the survivors. Unfortunately, there isn't
much solid cover for you to spawn behind. But...if you CAN spawn
somewhat close to the survivors, the corn stalks may allow you to get
rather close to the survivors. AND, because this is a very wide open
area, the ensuing horde may surround one or more of the survivors and
allow great stationary targets for Hunters to take advantage of. You
can try spawning behind the tractor in the middle of the field, which
works doubly well because 99.999% of survivor teams will navigate
through the field by passing by that tractor.

The vast...and I mean vast majority of survivor teams will get through
the corn field by running straight ahead, and once they reach the
tractor, cutting to the right and hopping over the fence near the
farmhouse. Once every other few blue moons...a survivor team will hug
the left after descending into the field and take the longer and more
dangerous path to the farmhouse. If by chance the survivor team takes
this path, know that Hunters have a HUGE damage pounce possibility from
the top of the hay filled shed.

*HUNTER TIP*
Assuming the survivor team is going to take the shortest path through
the corn field (which most do) look off in the distance behind the
small shack near the farmhouse. See those silos? You can get up there,
you know! And believe me, a pounce from up there hurts! Using wall
jumps to ascend to the top, after reaching this perch, you can pounce
freely without hitting a ceiling or invisible wall resulting in some
magnificent distance for you.

There is a barn near the farmhouse that can contain supplies and will
always have an ammo stockpile. In VS mode, this is a pretty uncommon
place to see the survivors camp out, but if they at least go into the
barn to check for med packs or whatnot, it may allow you an extra quick
attack to get off on them before they start the event.

*BOOMER TIP*
If you're a Boomer here and the event hasn't been started yet, DO NOT
SPAWN. The survivors will likely huddle into a corner or camp out
upstairs resulting in pretty much a useless horde drawn by your vomit
attack. Instead, save your spawn until the Tank comes. Since most
survivor teams like to run outside for the Tank, getting your vomit
attack off on the survivors as they head out into the wide open area
can be devastating!

Like all of the other finale events in Left 4 Dead, a flow chart is
followed to progress through the event.

1) Horde
2) Tank
3) Horde
4) Tank
5) Last ditch effort Horde + Tank

There are 2 very common strategies for the survivor team to employ
here.

The first strategy (and the outright most common) is for the survivors
to huddle up in the corner next to the gun rack in the room with the
supplies. From here, the infected need to more or less come at them
from one direction, though the occasional zombie will jump onto the
table that contains the med packs and land a hit...

*SMOKER TIP*
A breakable wall across from the corner the survivors are camping in
can allow you to try and separate one from the team. You can also try
pulling one of the survivors from outside the kitchen windows.

Unfortunately, Hunters here are rather useless and worthwhile pounces
are few and far between. Instead, it may be more beneficial to try and
go in for a quick claw swipe. Remember, claw swipes can hit multiple
targets. Pounces cannot! If the Boomer on your team has already
spawned, he can use the same strategy as the Hunter or try and stay
alive long enough to vomit on the survivors as they run outside to deal
with the Tank.

The second strategy is for the survivors to run upstairs and cover the
4 entrances from that hallway. 3 survivors will cover a bedroom each,
while the 4th covers the staircase. From below, Smokers may be able to
pull that survivor down the staircase where a Boomer can use his vomit
attack or a Hunter can try for additional damage. Otherwise, if a
survivor gets pulled, a Boomer may be able to vomit on one of the OTHER
survivors as the pulled survivor needs assistance and one of them must
temporarily leave his/her post.

*TANK TIP*
When it's Tank time, there are hay bails and large logs that can be
used to smash into the survivors. This is a very wide open area, so
it's not Tank friendly, and should you get set on fire, you cannot
extinguish it. If you can, make good use of your rock throw ability,
and remember that there's no shame in passing the Tank to someone else
if you need your teammates to respawn. Boomers especially.

*HUNTER TIP*
When it's Tank time, perching atop the house and landing a big one on a
survivor as they scatter is amazing. A Boomer's horde here to slow them
down can provide you easier targets. From atop the house, you should be
ashamed of yourself if you manage a pounce of less than 15 damage!

When the rescue vehicle arrives, know that the back hatch of the truck
takes a while to open up and allow the survivors entry. Also, the
truck's ramp is rather narrow and has a tendency to push survivors off
to either side forcing them to try and make it back up the small ramp.
With a horde in the way, it can get messy. Smokers here are wonderful
as they can drag a survivor back...possibly past a horde. An incap here
will pretty much guarantee a loss of a survival multiplier. Tanks can
also take advantage of the truck's ramp. If the Tank player can reach
the truck before the survivors can, have him stand in the doorway to
deny the survivors entrance to the rescue vehicle! This will keep the
survivors in play a little longer and can provide a great opportunity
for Hunters to land massive pounces from atop the barn or the
farmhouse!

Blood Harvest's "last ditch" horde and Tank is one of the most
effective and easy to use in Left 4 Dead, and I've been in plenty of VS
matches where even though the rescue vehicle has arrived, nobody has
made it because of good planning on the infected team.

Good luck!
