Doom 4 Walkthrough
Version 1.1.
Acknowledgements and Caveats
Thanks, id Software for making such a great game!
Also, watching zomeister's Pistol-Only walkthrough helped me with several
strategy points. So props to that individual: please watch the madness if
you want to be inspired:

Caveats: I have not read the "Official" Guide by Prima Guides at this
point. I may do so soon and amend this guide, as time permits.
Introduction and Game Mechanics
Overview
Welcome to Doom 4, an intense and sensory First Person Shooter!
The game is set mostly in a large energy facility on Mars, with occasional
forays into Hell!
The game is heavy on action and fighting, and it keeps its cut-scenes
short and punchy.
The visuals are impressive, contrasting space-tech with organic demons.
They are also pretty gory: potential nightmare fodder for kids. Even
though you will plow your way through hundreds of monsters in these
missions, at least none were human at the time of death.
Basic Plot Summary
You awaken to being chained to a bed, and quickly assume the hero's role:
combatting an experiment with Hell gone awry. Over the missions, you'll
see that cutting-edge research into new energy sources degenerated into
cultish madness, including ritualistic sacrifices. It's up to you to stop
the unleashed demons.

Weapons
Pistol
What the Pistol lacks in power it makes up for by having unlimited ammo.
The lack of power can be an advantage if you are trying to stun a demon in
order to Glory Kill it, if you are trying to extract more stuff from the
kill.
My upgrade strategy: save the upgrades for the end, or maybe induldge in
the first 1 point upgrade. There are more important ways to spend one's
upgrade points.
Shotgun (available Mission 0)
Although the shotgun is eclipsed by the Super Shotgun (which is much
better, once upgraded), you'll have no real choice for the first few
missions. Because of this, it isn't really worth putting Weapon Upgrade
points into the shotgun, at least not until later in the game if you are
trying to get 100%.
When you get to the first Field Drone, the Shotgun is the only weapon you
have to modify, so you have to get a mod at this early point: go for
Explosive Shot, which is easier to use to get the "Twofer" Challenge (for
Mission 2).
Cyber-Mancubi count as Mancubi for the Changed Shot Upgrade Challenge.
(Technically, the game refers to this weapon as the "Combat Shotgun", but
nobody calls it that.)
Plasma Gun (available Mission 2)
Although it's individual shots are rather weak, it fires quite rapidly.
More importantly, Heat Blast is a really powerful Weapon Modification.
Basically, it allows you to kill everything near you at the same time
without using ammo, BUT it requires you to shoot the gun to charge up the
blast. There are 2-4 places you can use the Heat Blast and Quad Damage
Powerup to really plow through large numbers of demons.
I haven't found the Stun modification to be very useful: it wastes ammo,
it's hard to stun more than 2 demons, they don't stay stunned long, and
you still have to kill them (taking both time and ammo usually).
Assault Rifle (available Mission 2)
Each individual shot from the Assault Rifle is rather weak and becomes
weaker and harder to hit from a difference. Few demons can be killed with
a single shot; expect a cacodaemoon (etc) to take 30+ shots even up close.
ihe Tactical Scope changes things a bit: it makes the thing pretty
effective for sniping, and the upgrades make it pretty damaging. Even so,
it's a bit tedious killing things with this weapon.
However, it makes for a nice change, since the opportunities for sniping
are few in this game. You can usually get the challenge upgrade naturally
over the course of the game, but you can also replay an earlier mission to
get it pretty easily.
The Mini-Missiles seems like a cool upgrade but they aren't that powerful
or predictable. One nice use is for dealing with multiple Lost Souls. Most
other monsters are too strong for this to be an elegant attack.
Super Shotgun (available Mission 4)
A weapon big enough that it'll at least distract anything. Fully upgraded,
it's my weapon of choice for Hell Knights, or combats with a long chain of
individual demos.
The challenge upgrade can be a bit difficult: I usually get very close to
one demon and shoot through it to get to another one close behind; this
seems easier than lining them up side-to-side.
Chain Gun (available Mission 6)
A powerful weapon that is a bit annoying to use because it takes a a few
seconds to start up.
The Gattling Rotator works, but you have to hold down the modifications
button the entire time: I don't really like that.
The Mobile Turret mod is a great way to deliver a lot of damage. I usually
try to fully upgrade this modification since it's useful against bosses.
Gauss Cannon (available Mission 5)
The most powerful standard weapon, even without mods. Siege Mode is the
most powerful mod (by far), and it is strongly recommended. Its challenge
upgrade is easy too.
The Precision Bolt mod is also pretty good but it's a lot harder to fully
upgrade and only kills once thing at a time, so I seldom use it.
BFG (available Mission 8)
The Big F-ing Gun. This will clear out a whole room of demons, but it can
be a little unpredictable in how it works.
Ammo is found individually, and you always have a limit of 3. However, the
Ammo Boost II rune WILL cause enemies to randomly drop BFG ammo when they
die so there isn't too much of a shortage.
Chainsaw (available Mission 2)
This crazy melee weapon will definitely kill any monster (except Bosses)
in range that you have enough fuel to kill. The initial capacity is 3 Fuel
Units, which is the amount in every gas can. Each Argent Cell upgrade to
the Ammo Capacity increases your capacity by 1 Fuel. So fully upgraded,
you have a capacity of 7 Fuel Units.
Killing with a chainsaw is considered a Glory Kill that'll dump a huge
pile of ammo.
Fuel to kill various demons:
* Imp: 1
* The Possessed: 1
* Unwilling: 1
* Possessed Guard: 1
* Possessed Securities: 1
* Hell Razer: 1
* Hell Knight: 3
* Summoner: 3
* Cacodaemon: 3
* Pinkie: 3
* Spectre: 3
* Revenant: 3
* Mancubus: 5
* Cyber-Mancubus: 5
* Hell Baron: 5
Weapon Upgrade Path: In My Humble Opinion
Here's how I upgrade my weapons. I usually upgrade one-at-a-time, simply
because that spaces the Upgrade Challenges out more.
* Plasma Rifle / Heat Blast
* Rocket Launcher / Lock-On
* Super Shotgun
* Gauss Cannon / Siege Mode
* Assault Rifle / Tactical Scope (Often I get the first two upgrades
before Siege Mode is available)
* Pistol
* Rocket Launcher / Remote-Detonation
Monsters
The Possessed, Unwilling
These idiots simply stagger around, vaguely coming toward you.
In Nightmare mode, they do quite a bit of damage; in easier modes they are
merely pesky.
Imps
Monkeys with fireballs with great aim. You have to move constantly and
keep a lookout to avoid getting hit.
They can take a fairly large amount of damage when they are climbing
around on vertical surfaces.
For players in Nightmare mode, Imps will probably cause more deaths than
any other demon.
Possessed Engineers
Somewhat like the Possessed, except they explode when they die, and they
charge at you to cause trouble.
These guys are walking bombs - typically when they die they'll fly away
from you which mitigates the problems. But some weapons might cause them
to fly at you, and they'll do moderate damage.
Even if you jump from above them and Glory Kill them, it does not count as
a Death From Above Glory Kill (at least for the purposes of Rune or Combat
Challenges). I'm assuming they their firey plume keeps them safe ? TODO:
read the damn codex on this
Possessed Soldiers and Possessed Securities
These two monsters differ in that the latter has shields.
They have 3 attacks:
* Plasma Volley: an attack of many straight-moving weak plasma baubles
* Plasma Grenade: a stronger attack, similar to the Rocket Launcher /
Remote Detonation. It expands before blowing up like a bomb.
* Melee Attack: these are fairly weak for Possessed Soldiers, but they
are quite strong from the shielded soldiers
The shields are a big difficulty: the Gauss Cannon or Chainsaw are the
surest ways to kill them - you'll run into them before you have the Gauss
Cannon. Otherwise, try running around them (around a structure) or jumping
over them. Also they have to put their shields down when the jump/drop.
Hell Razers
These hellions attack with a laser in their arm, or a melee attack.
They have a lot of hit-points, but they aren't too hard to kill.
Lost Souls
These little punks are very damaging.
It's best to snipe them from afar (effective weapons: Assault
Rifle/Tacticle Scope, Rocket Launcher/Lock-On, BFG). At the last moment
when they are swooping in on you, the Shotgun or Super-Shotgun is probably
the best, if you're quick.
They can make little turns, but you can sneak behind pillars or protected
areas.
Hell Knights
These are brutal melee attackers.
They will jump toward you very fast.
It is best to approach them right after an attack (Super Shotgun, Gauss
Cannon) then back-off - a kind-of dance, or just use the Chainsaw which'll
definitely kill them if you have fuel.
Summoners
These red-dressed ladies fire intense energy beams along the floor.
Fortunately, the shot comes with a harmless pre-shot, so if you see a
short red flame running along the ground, get away from it.
The Rocket Launcher / Lock-On's Multi-Target Upgrade requires 5 kills on
Summoners, so if you want to get that upgrade, you'll want to kill every
summoner with lock-on rockets. That said, this upgrade isn't particularly
useful.
Cacodemons
Big floating eyeballs with gigantic purple missiles.
They do (as a hint notes) have a weak point near their eye opening, and
precision shots with the tactical shot of the assault rifle can kill it
from afar pretty quickly.
Revenants
These tough lanky flying demons wear a backpack to shoot you from above.
They can take a significant amount of damage.
The visible patch on the sternum (center of the chest) is a weak point.
Pinkies and Spectres
These are big charging idiot monsters. The Pinkies are substantially
heartier. They are literally pink. The Spectres are essentially camoflaged
Pinkies. They blend into their surroundings.
I suggest using Super Shotgun, Chainsaw, Gauss Cannon on these guys. But
really, any weapon will work.
Their tail/backside is their weakness. A single point-blank Super Shotgun
blast to the base of the tail will usually kill it. (Two such shots
definitely will, but most of the time the Pinky will start moving before
you can get a second shot)
Mancubi and Cyber-Mancubi
These large (obese) demons shoot damaging fireballs. The Cyber-Mancubi are
somewhat more annoying because their shots leave a toxic (green) residue
that you must avoid (it only lasts a few seconds).
The visible patch on the sternum (center of the chest) is a weak point.
Hell Barons
These are like Hell Knights except that they can shoot missiles. With
horns.
They are really not that tough, because they can be taken down by 2 Gauss
Cannon / Siege Mode shots.
Equipment
Generally speaking, most players use mostly one type of Equipment: the
Frag Grenade. It is effective, you get it early on, and it is easy to
understand.
The Siphon Grenade is substantially harder to aim, and less damaging, so
it isn't used too much.
The Hologram (sometimes called the Decoy) seems like a good idea, but I
really haven't found places I personally like to use it.
Contact me if you have suggestions for Siphon Grenades or Holograms!
Frag Grenades
These have both good radius and damage and are recommended. I know that as
a beginner, I under-used them. One problem is that they take a long time
to regenerate until you get the first Praetor Suit Equipment Upgrade.
Siphon Grenades
These pull energy from demons in their radius and give it to you. But the
amount transferred isn't that great, so it tends to be overlooked.

D'Nur
So, if you 100% the game you should have 142 - 126 = 16 unusable Weapon
Upgrade points at the end. Another way to look at it: there are 16 extra
Weapon Upgrades Points.
That said, the extra combat upgrades have to be earned, so earning 100% on
one playthough (ie without taking advantage of Mission Replay or dying),
is logistically tricky, if not impossible.
Checkpoints
Checkpoints save your ammo, health and armor levels, as well as the
locations of pickups of the same nature.
On the other hand, Secrets, Argent Cells, and Elite Guards are all saved
without making a checkpoint.
This system usually works quite well, but the Argent Cells have a
side-effect of filling up whatever power you upgrade. This isn't saved
unless you find a checkpoint elsewhere. This rarely comes up besides in
Mission 7 where we provide some advice.
Checkpoints, in Summary
Things that are captured immediately:
* Secrets, Argent Cell, Elite Guard usage
Things that are preserved by checkpoints:
* demon kills
* pickups (except those dropped by demons)
* Health, Armor and Ammo levels
Things that are lost by dying after a checkpoint:
* the fill-up delivered by Argent Cells
* partial (pending) powerups at the time of the checkpoint
Your Dossier
These are accessed by the central button on PS4.
These pages are introduced pretty well described by in-game tutorials, so
I'm not going to repeat all that information.
* When you get an Auto-Map, the effect is to enhance the map in your
Dossier. Praetor Suit upgrades can improve the map in various ways
* Weapons and Praetor Suit Upgrades are explained over the first few
Missions
* Tutorial Codex pages are automatically added to the Codex page.
* The Codex page will let you see if you have missed any Codex Entries
Navigation
Your dossier has a 3-d map that is pretty nice, but it doesn't give a
coordinate system, nor labels for places, nor even a reference direction,
like North. It does provide some icons that can be used as landmarks.
Fortunately, almost every location in this game looks somewhat different,
so it's not so bad. But pay attention to the names given to certain major
rooms/locations, since usually if i give it a name, then you'll arrive
there a few times.
Difficulty Levels
Based on my own experience (and I could be wrong):
* difficulty levels affect:
* damage done by demons
* gains from ammo, armor, and healh pickups
* runes: Rich Get Richer
* difficulty levels do not affect:
* number or placement of demons
* chainsaw
* secrets (except the size of an Armor pickup)
* runes: In-Flight Mobility
* i'm not sure if these are affected:
* health of monsters
* damage of user's weapons
* environmental damage to the user
* environmental damage to the demons
Ultra-Nightmare is the same as Nightmare for this information.
Runes
I provide hints about how to complete the Runes Challenges where you come
across them. These are hints about when to use runes, and how to upgrade
them (as easily as possible- both on a single playthrough as well as using
Mission Replay).
Vacuum
Easy to get and the most important rune. Upgrading is easy as well - jump
make sure to remember to equip it after you complete the challenge (it
won't remind you in nightmare mode).
Dazed and Confused
This rune comes in handy for the Bosses at the end of Mission 11, and for
fulfulling the Combat Challenge "To Be Knighted" for Mission 4: without
the Jump Boots, Death From Above Glory Kills on Hell Knights can require
some setup.
Ammo Boost
Very useful: I have this on much of the time.
Equipment Power
This will make your grenades pretty powerful, and is basically trivial to
upgrade (just throw 30 grenades with the rune enabled). If you upgrade
your Equipment Power using Praetor Tokens, it'll make grenade throwing
faster, and hence make the upgrade easier to get and more powerful.
Seek and Destroy
Useful for most berserk powerups - and those are great times for upgrades.
Savagery
Useful for most berserk powerups.
In-Flight Mobility
This rune is almost vital for the last boss fight - and the upgrade is
pretty critical too.
It might make sense to work on this upgrade at the same time as the Dazed
and Confused upgrade.
Challenge tips: there is very little room for error. You must single jump
across the split every time - if you double-jump (which is tempting,
because the separation is pretty wide for a single-jump), it'll waste
valuable time. The crux is probably hitting the annoying mid-air relic in
the second half of this course, but note that you have two chances at it,
since you have to jump left-to-right then right-to-left in that area.
Obviously most people aim to get it in the first jump, but it's good to
keep cool if you miss it on the first jump since you have another chance.
Upgrade notes: You need to get 25 Mid-Air kills. Note that "Mid-Air"
refers to you, not the demon. As a result, glory-kills from above are
probably the easiest way to get this, so it makes sense to try to combine
this upgrade with the Dazed and Confused upgrade.
Armored Offensive
Very useful, easy to upgrade, just keep it on a lot. Also, the upgrade is
measured it armor points you pick up. In particular, picking up a
Mega-Health will contribute 200 points for this upgrade.
Blood-Fueled
Useful during Berserk Powerups - this is also a good time to get the
upgrade.
Intimacy is Best
There's only one place this upgrade is helpful (unless you count mission
replay): the Atop the Mountain challenge in Mission 10.
Upgrade hint: although you might think this would be efficient to get in
conjunction with the various glory-kill upgrades, it's probably best to
upgrade this by finding a group of The Possesseds and staggering them over
and over again with the pistol. It only takes about a minute or so.
Rich Get Richer
This is quite useful in several Argent D'Nur fights.
To upgrade this, you need 12 Armor Fillups. An Argent Cell counts, as do
Mega-Healths. But you'll struggle to get about 6 of those. One options is
to use Toxic-Sludge to do a single point of damage -- Unfortunately
there's really only one fight [Mission 10, Pounding Rock Area] that has
easy access.
Upgrade hint: in Nightmare mode, getting up to full Armor is difficult,
except when the Mega-Health powerup. If you don't mind dying multiple
times, there are a few Mega-Healths you can use to get the upgrade. you
can die and multiply get several Mega-Health, Toxic Sludge is a convenient
way to drop just a single health at a time.
Saving Throw
A possibly useful safeguard in Ultra-Nightmare or Arcade Mode, but in
casual play for campaign mode, not too useful.
Mission-by-Mission Plot Summary (SPOILERS!)
For the most part, the plot in this game isn't very important. But I
wanted to summarize the whole plot briefly so casual players can refresh
their memories.
Before any mission, you, Doomguy, are awoken from your slumber. You learn
in a cut-scene that a satellite must be realigned to learn the status of
the complex: THE UAC (Mission 1) (abbrev for Union Aerospace Complex).
First you must gain access to the .... From there, you are taken to
RESOURCE OPERATIONS (Mission 2): first half of mission is to realign the
satellite (merely requires getting to a particular terminal). The second
half of the mission is to get to a VEGA Terminal, where you learn the
extent of the catastrophe.
The discussion is interrupted by news of an emergency in THE FOUNDRY
(Mission 3). At the end of Mission 3, you learn Olivia Pierce is the
source of the disruption, and that she's headed for a hugely concentrated
argent beam. The first plan of attack is to disable the filters that feed
argent energy to the tower in the ARGENT FACILITY (Mission 4). But, of
course, it turns out that the Tower is still dangerous, and you have to
get up there to try to disable it.
Before climbing the ARGENT ENERGY TOWER (Mission 5), you have to get to
it, which involves of a lot of jumping around on catwalks (what I call
"The Bridge"). Getting up is similar. Ultimately, Olivia beats you to it,
and the portal is opened.
After that, the missions have a general arc: trying to close a portal to
hell.
The force of the portal opening transports you into hell. This area of
hell is known as KADINGAR SACTUM (Mission 6): where you were excavated
from. Somehow, they set up a portal at the end of the mission that returns
you to the ARGENT FACILITY (DESTROYED) (Mission 7).
This time, you are here to catch a tram to the ADVANCED RESEARCH COMPLEX
(Mission 8). You'll finally meet Dr Samual Hayden. Then you'll go to the
weapons division, LAZARUS LABS (Mission 9). This level concludes in a boss
fight, in two parts. Part 1: you fight the demon on Mars and rip out the
argent accumulator, which sends you back to hell. Part 2: in Hell, ...

TITAN'S REALM (Mission 10).
NECROPOLIS (Mission 11).
VEGA CENTRAL PROCESSION (Mission 12).
ARGENT D'NUR (Mission 13).
Using this Guide
Secrets, Field Drones, Argent Cells, Rune Challenges are all written in
uppercase at their secret location, with dotted notation where the first
number is the mission and the secret is the index of the location in the
Dossier Overview/Map page. For example, SECRET 14.3 would be the third
secret in the dossier in mission 14 (but there's really only 13 missions).
This is intended to facilitate searching.
As a perhaps dubious consistency I will use all-caps the first time you
meet a monster or can collect a weapon. Subsequently, I will use title
case.
(In the case of monsters, there are two grammatically annoying ones: The
Possessed and Possessed Security. I'm just going use them like they were
real nouns, and i'll therefore pluralize them as The Possesseds and
Possessed Securities.)
I will use title case (ie first letters capitalized) for various other
collectibles: Suit of Armor, Small Armor, Health Station, Mega-Health,
etc.
Similarly CHECKPOINT is always written uppercase to indicate that the game
will give a checkpoint. The significance of that is that it is nice to
load up on supplies right before getting the checkpoint. (So that if you
die, you won't have to get the supplies again)
About this Guide
This is the first Walkthrough that I (Dave Benson) have written. I hope
you find it useful.
I am no expert game player. I just really like this game, and decided to
write a walkthrough since the one like I wanted didn't exist.
I found it to be an interesting challenge, mostly due to the difficulty of
describing locations.
I welcome contributions, compliments, suggestions, errata, strategies,
complaints, and donations. Contact me via github for details, or submit
bug reports:
https://github.com/davebenson/doom4-walkthrough
Mission 0: Pre-UAC
At the beginning of the game, you wake up chained to an operating table.
As you break out of your bonds, four demons surround you, your first
encounter with THE POSSESSED.
Before you have control, you kill one by hand, and grab a pistol.
Shoot the remaining three.
Interact with the screen (to the right of the door) and proceed into the
central room with the Praetor Suit. Interact with it, and meet Dr Hayden.
Ultra-Nightmare skips the Mission 0 fights.
Mission 0: Mini-Fight 0.1: Glory Kill Tutorial
You will come upon a staggered The Possessed. After killing it, kill the
remaining 4 weaklings.
Mission 0: Mini-Fight 0.2: Meet the Imp
Interact with a corpse to get the SHOTGUN.
Enter the next room.
A quick cut-scene will play as the IMP scurries down from the rafters.
Kill it, obviously (using the Shotgun).
Mission 0: Fight 0.3: Blue Elevator Chamber
You exit the anteroom to see 8? The Possessed worshipping an Orb. You can
Glory Kill them if you need health or kill them en masse by shooting the
barrel.
After destroying the Orb, about 15? Imps will gradually materialize. Keep
moving! There are two sheltered areas: the entrance area, and a
control-room overlooking the main chamber.
Grab all stray stuff before entering the elevator. CHECKPOINT.
Mission 1: The UAC "Rip and Tear"
Mission 1: Intro
The mission starts with you exiting an elevator, and dropping onto a lower
plane. 3 small armor pieces are there; proceed upward to find CODEX ENTRY
"Environments / The UAC".
As you approach another tall cliff, you can see Imps running off into the
horizon: these can be shot but it's not worth the effort. You can also
shoot The Possesseds below, but it's better to use them as walking health
bonuses.
Mission 1: Fight 1.1: Pre-Blue-Keycard
This is the first real fight of the game. It occurs on a 2-level
dual-figure-eight structure.
If you are quick and accurate, you can target some imps on the cliffs
above, and you can shoot at The Possesseds below. In my opinion, these
aren't worth spending time on.
Like many fights throughout the game, you will learn your own opening
gambit. For me, I target the 2 POSSESSED SOLDIERS that appear right in
front of you: one in the center in front of a pinnacle, and one at right
near a barrel that can be shot. After that, just keep moving and shooting.
You'll be able to recharge over the next easy fight, so use up all the
health and armor during the fight.
Mission 1: Keycard and Secret
After the demonic threat is neutralized, a gate opens up, opposite the
entrance location. However, another gate immediately (requiring the Blue
Keycard) blocks progress. Turn right and walk down a tunnel. Behind a
large block is a corpse with a Blue Keycard.
After getting the keycard, stand on the block and look around for a tunnel
above you. You should jump to it, and pick up SECRET 1.1 and your first
collectible, COLLECTIBLE 1.1 "Combat Shotgun Model, Blueguy".
Continuing through the tunnel, you'll get to the gate, which will open.
You'll get some ammo, but more importantly, the FRAG GRENADE, which is
very useful, especially once your suit's equipment upgrades are done.
Mission 1: Mini-Fight 1.2: Stray Possessed and Imps
There's about 6 The Possesseds and 3 Imps.
After killing those guys, enter the cave to the right (at the top of the
incline). You will find some worshipping Possessed and an Auto-map.
Continue out the cave to find a Praetor Token (ELITE GUARD 1.1) on the
right before jumping down.
Mission 1: Mini-Fight 1.3: Stray Imps
As you drop down the last level of this spit of land, 5 Imps will attack
from various directions.
CHECKPOINT.
After that, look for the large tank with TRI 9-C printed on it, and enter
its lower level. There is a lever through that you should interact with
then enter the Classic Doom Level. Exit the structure and you should be
able to see up the path to SECRET 1.2, CLASSIC MAP 1.1 "Doom II:
Entryway".
Mission 1: Classic Fight 1.4: Classic Doom Level
There are 4 Possessed Soldiers standing on pedestals in here. I usually
use a Frag Grenade to kill the left one, then snipe the right one from
just under the pillar. The remaining two can be taken out one-at-a-time.
If you actuate the switch nearer the entrance, you can get some minor
booty. Mostly, this fight isn't worth the effort.
After this, jump onto the crates at the end of the landing bay, and jump
the chasm.
At the end of this area, you may catch a glance of the Field Drone flying
away to the right. But go left to an area with Health and Armor, and the
second CODEX ENTRY "Environments / The UAC".
Mission 1: Fight 1.5: Just Across the Chasm
Go back, and to the right where you saw the Field Drone; it's floating
right ahead. Interact with it: I tend to get Charged Shot as it makes an
upcoming challenge easier, but either (or none) can be used.
You will come across some The Possesseds worshipping a corpse. There are 3
Possessed Soldiers around in the peripheries as well, and they will be
join in the fun by some Imps that'll spawn, potentially close to you.
After killing them, CHECKPOINT.
Mission 1: Fight 1.6: Pre Entranceway Area
This canyon can be approached in two ways:
* go directly up the canyon
* back up and ascend some cliffs to the left (there's a Medium Health
visible), cross over the canyon on a land bridge, then turn left and
climb up a yellow metal wall.
Either way, expect 5+ Imps (plus some The Possesseds).
CHECKPOINT.
You should see a suit of Armor on a small plateau. Just before that, at
the canyon's bottom, look around for a small backfacing greenlit "secret"
tunnel. It leads to a cliff with SECRET 1.3 to COLLECTIBLE 1.2 "Imp Model,
Classicguy".
Mission 1: Fight 1.7: Station Entrance
You can approach this fight up the main road (over the plateau with a suit
of armor), or from the side using the plateau to the right. Use grenades
to knock these forces back, and retreat to snipe at the various demons.
It's about 6? Possessed Soldier, 6? Imps, and 12? The Possessed.
Search all over for ammo.
Now, go up to the top level. You'll see a medium Health. And at the end of
both of the broken tracks there are carts containing Health and Ammo.
Enter into either of the twin doors, there's some armor - pick it up if
needed, then proceed to the waypoint.
Mission 2: Resource Operations "Know Your Enemy"
Mission 2: Notes on Combat Challenges
* Two-fer: This is easy with the Explosive Shot: use the Weapons Mod key
and shoot a Possessed that is in close range of another Possessed. Or
stagger one in order to line them up carefully. It can be done without
weapon mods by staggering two Possessed and getting really close to
one and shooting through it to the other staggered being.
* Variety is the Spice of Death I: perform 5 different Glory Kills on
the Possessed. There's a lot of options; use the Pistol (instead of
Shotgun) to more reliably stagger (as opposed to kill) them.
* Quite the Explorer: Find 3 Secrets. This should be pretty easy, with
this guide.
Mission 2: Mini Fight 2.1: Before opening hatch
5 Possessed wait here, and 2 Imps spawn quickly. Kill the Imps and use the
Possesseds to work on either Challenge "Variety is the Spice of Death I"
or "Twofer" (this is easiest using the Explosive Shot modification).
You can't open the hatch yet: "Low Power". Instead, open a door to find a
number of The Possessed, and keep going to an Imp at the top of the
stairs. "Reset Power" (by interacting with a screen), to watch a bit of a
cut-scene featuring an Olivia Pierce recording.
Looking down at the stairs from the top, you should see a platform at your
level with a blood smear on the back wall: a standard marker for a secret
in this game. Go there, and look for some ducts to climb through. You'll
get to SECRET 2.1 and a suit of armor.
Back at the bottom of those steps, find an Auto-Map: use it.
Continue to the waypoint and an Open the Maintenance Bay Door.
Mission 2: Mini Fight 2.2: Tiny fight in catwalk area with Original Doom Level
Some Possessed are followed by 3 Imps. Go where they originated onto a
crane-like catwalk. Jump over its left railing, and look for a platform
somewhat above you: jump to it. Look for the Lever and pull it.
Jump back down, keeping an eye out for some Imps that'll spawn right
around you. You should see the SECRET 2.8, CLASSIC MAP 2.1 "Doom - Hangar"
up a small staircase with some Health and Shotgun ammo.
After that, open the door with the waypoint to meet the Possessed
Engineer. Shoot him and he'll fly back, killing the numerous Possesseds in
the background.
A battle awaits after opening the next door.
Mission 2: Fight 2.3: U-shaped catwalk area
This can be a difficult fight, but judicious use of Grenades, Barrels, and
Possessed Engineers can make it fairly painless.
Post Fight: There's CODEX ENTRY "Environments / Resource Operations" and a
door.
You can enter the room through a path with more goodies by looking for a
screen in the left of the control console that you can interact to "???".
This will stop the fast moving elevators at the central part of the U.
Climb up the elevators and enter through the second story for health,
armor, and shotgun ammo.
No matter which way you go, you'll be in a locker room with some Shotgun
Ammo, the Chainsaw, and a Health Station.
Mission 2: Fight 2.4: Industrial Train Depot
A long hallway fight, with a bit of a side-corridor at the end.
You can fight it from the entrance gate, or you can charge in. There's a
few barrels that you can shoot to good effect; grenades are also helpful
here, as can be the chainsaw.
??? CHECKPOINT.
Mission 2: Getting the yellow keycard
Cross the train-tracks on the far-side of the room from your entrance. You
will see a gas canister across the tracks. Turn left and carefully go
through the hatch which automatically opens and closes. It is an elevator.
When the door opens on the upper level, there should be a large armor.
Take it and go forward. There should be a train on the left leading back
to the Industrial Train Depot, and on the right is a Security Station.
Drop drop and take out the few The Possesseds.
Mission 2: Mini Fight 2.5: In front of Security Station
4 The Possesseds.
Load up on health and armor before proceeding, since the next fight can be
tough.
Since you don't have the Yellow Keycard yet, you will have to go down the
hall to a developed outdoor area.
CHECKPOINT.
Mission 2: Fight 2.6: Developed Outdoor Gore Nest
Before destroying the gore nest, take out the 6? The Possesseds possibly
using Glory Kills to get more health. I tend to use the pistol to save
ammo.
After destroying the Gore Nest, a large number of Imps and Possessed
Soldiers appear, keep moving and shoot the barrels to kill some of them
while saving ammo. Make note of the two supply caches containing
ammo+health before starting.
Hint: The chainsaw is useful here to kill 3 demons and get lots of ammo.
Mission 2: Getting the yellow keycard (continued)
On the lower level, Call the Elevator and see a replayed cut-scene of the
demon carrying the Yellow Keycard guard. Enter the elevator and press the
button.
On a catwalk area you'll find some health, FIELD DRONE 2.1, shotgun ammo
and the corpse of the Yellow Keycard guard. I recommend waiting to use the
field drone until you have the Plasma Rifle. Take the Yellow Keycard and
watch out!
Go through the hatch then drop down into the Industrial Train Depot, right
in front of a Yellow Keycard Door.
Optionally, you can go through the yellow door and then into a
control-room area which has the ASSAULT RIFLE. But go back to the
industrial train depot to obtain a bunch of secret stuff.
So, retrace your earlier steps to the Security Station which you can now
access! Take the supplies and interact with a terminal to unlock the doors
Continue re-tracing your steps. In the hallway, on the floor to the right,
is a Hatch. Open it and drop down for SECRET 2.2. Find some The Possesseds
and 2 Imps, along with ELITE GUARD 2.1 and a PLASMA RIFLE (SECRET 2.3). To
get out of this area, you'll find a Grate that you can kick open.
This will drop you into the location of the Developed Outdoor area fight,
which is now vacant, but some Health may have re-appeared.
Continue retracing your steps by pressing the Call Elevator button on the
lower level, and find the Field Drone. I recommend using it to get the
Heat Blast modification for the Plasma Gun.
Now, instead of going forward, turn right into a door that was unlocked
when you accessed the Security Station a minute ago. This is SECRET 2.5.
Follow the blood to a duct, crouch, and go through to get to a steamy room
you could see into earlier. SECRET 2.7, ELITE GUARD 2.2, and some armor
and health.
Exit the door by interacting with it, to the Industrial Train Depot.
Go through the Yellow Keycard door, and Open the Airlock from the control
room in this area. Take the Assault Rifle if you didn't get it earlier.
Enter the Airlock, then Cycle it to access the red outdoors.
Mission 2: Fight 2.7: Outdoor Fight
This sprawling fight occurs mostly in the lower level of a two-level area.
It's mostly Possessed Soldiers and Imps- lot's of them. I recommend
running through using Heat Blast (watch out for explosive barrels), and
using the Chainsaw on the Possessed Security. Then grab the Berserk
Powerup to kill the majority of the remainder.
Mission 2: Accessing the Secret after the Outdoor Fight
Follow the uphill path from the entrance to the second floor. Right as you
get onto the second floor, look for a bloody crate.
Jump onto the crate, then jump up and forward onto a duct. Turn right and
go shortly up along the top of the duct. Turn around and jump onto a
higher, shinier duct.
Walk along it, with breathtaking martian views, keeping an eye out for a
yellow landing to the right of the duct.
Jump onto the landing - and jump again to a rooftop.
Walk on the roof to an alcove in the building (turn left and go over a
pipe, then turn right into a duct), to find SECRET 2.6, COLLECTIBLE 2.1:
"Doom Marine Model, Doomguy".
Go back - and on the rooftop look left for a hatch that you can use to
drop down into the control room with the in-game waypoint.
Mission 2: Realigning the Communication Satellites
There's a corpse whose handprint will grant you access to begin the
realignment process. Interact to achieve this morbid security victory.
Follow waypoints, to go down the elevator down to the next tiny fight.
Mission 2: Mini Fight 2.8: Imps after Aligning the Bridge
3 Imps climb up; one more on bridge.
Mission 2: Crossing the bridge
Jump across where the surprising Imp jumped up. Turn right and jump where
a green light strip can be seen.
There are symettric platform to the left (away from the base) and right
(toward where you came from). Jump to the right.
Take the platform back toward the building: there should be a suit of
armor in front of you.
An automatic door will open, with 2 Possessed Soldiers and 1 Possessed
Security. Toss a grenade back in. The chainsaw can be a good way to deal
with the Shielded guy.
CHECKPOINT.
Mission 2: Mini Fight 2.9: VEGA Terminal Entrance
1 Possessed Security and 2 Possessed Soldiers. (Use a grenade or Heat
Blast or a chainsaw.)
Mission 2: Fight 2.10: Entranceway / Control Room Area
Three Imps and a few The Possesseds. In the entrance hallway, there's a
door to the right that leads to a Munitions Crate.
There's a assault rifle and CODEX ENTRY "Monsters / Possessed Security"
here.
In the control console area is a screen you can use to open the next door.
Mission 2: Fight 2.11: VEGA Hallway
A Possessed Soldier will run in as soon as the door opens.
Many The Possesseds, 3 Possessed Soldiers, and one Possessed Security.
Often the Possessed Security guards a hall to the left. It is worth
exploring. After climbing, an Imp will spawn in front of you. There is
ELITE GUARD 2.3 and a Munitions Crate.
Mission 2: VEGA Console area
This is a semicircular area with a central room.
But first, climb the crates at left and jump to find SECRET 2.4,
COLLECTIBLE 2.2, "Heavy Assault Rifle Model, Bronzeguy".
Enter the central room and watch the cut scene.
I recommend directing the Argent Energy toward your Health.
Mission 3: Foundry "Meltdown"
This mission has 4 Gore Nests you need to destroy. The first two can be
destroyed at any time. The third requires a Yellow Keycard and the fourth
requires a Blue Keycard. Getting the Blue Keycard requires a Yellow
Keycard.
Here's a quick description of each Gore Nest:
* Gore Nest 1: In the area behind the Field Drone
* Gore Nest 2: In the main area on a damaged platform.
* Gore Nest 3: Accessed by the Yellow Keycard, in a side-foundry.
* Gore Nest 4: Accessed by the Blue Keycard, in a locker room area.
The Main Foundry Area is the large open area with molten metal floors and
platform-walkways.
Notes on Combat Challenges:
* Three Possessed, One Barrel: the easiest opportunity for this is early
on, but you can also do it in the Argent Cell fight.
* Curb Stomp: Gore Nest 2 in the yellow molten Main Foundry Area is the
easiest, but there's a lot of random Possessed Soldiers around.
(Unlike Mission 9's "Variety Is the Spice of Death II", Hell Razers do
not count for this challenge)
* Quite the Collector: easy with this guide, I hope.
Mission 3: Mini Fight 3.1: Small Initial Gang
From the entrance area, exit into the Main Foundry Area. Jump left over a
gap in the catwalk.
The following fight does not spawn every time, especially if you die.
To the right, across a bridge, is a Possessed Soldier you can
Death-From-Above Glory Kill (as needed for the combat challenge "Curb
Stomp") and many possessed you can kill with one barrel (for Combat
Challenge #1).
Mission 3: Gore Nest 1 (Ante-Room)
Go back, though, through the door and find FIELD DRONE 3.1. Use it as you
wish (I tend to like Assault Rifle's Tactical Scope). There is also CODEX
ENTRY "Environments / Foundry" here.
Mission 3: Gore Nest 1: Mini Fight 3.2: Side-Foundry
Keep going back past some firey doors to a control console. You can try to
unlock the door (you don't have access) or watch a replay to see where the
Yellow Keycard Guard has gone.
If you turn so we are facing away from the control console, there are two
passages: the entrance on the right, and the left passage has the keycard.
If you enter that passage, you'll see that the catwalk has broken, and you
should barely be able to see a deceased guard on the other side, leaning
against a non-functional door: he has your Keycard.
If you try to jump across, you'll land on a platform below. To your right
is a small room with ELITE GUARD 3.1.
Follow the green lights to jump around and get up to a platform at the
same height as you started. The highest platform should say MIXOM. Look up
and right to see a square opening you can jump into: this is SECRET 3.1,
there is a suit of armor here.
Finally, jump to the platform you could see from across the gap. Interact
with the corpse to grab his biometric ID (ie his arm). Turn around: you
can jump the gap easily in this direction - but watch out for an Imp that
appears. The flaming door ahead is where the Gore's Nest is located.
Go to the control console (veering left) and use the dude's arm. Turn left
twice to find the Gore's Nest.
Mission 3: Fight 3.3: Gore Nest 1
This fight takes place in a somewhat dim and dirty one-story area. But,
it's just ~5 Imps and ~3 Hell Razers so it is fairly quick.
Mission 3: Gore Nest 2
This gore nest is the only one in the Foundry's Main Area.
Mission 3: Fight: Gore Nest 2
Pre-Fight: A good place to use the heat blast, and a fine place to work on
the Curb Stomp combat challenge. This is a mix of The Possessed, Possessed
Soldiers, Imps.
Gather supplies then destroy the Gore Nest.
As suggested by the Gas tank near the Nest, you may wish to use chainsaw
here since you might be low on ammo. Otherwise, just use a mix of weapons;
I often mostly use Heat Blast here. This is a mix of Possessed Soldiers,
Imps, and Hell Razers.
Mission 3: Fight: The Tunnels Above Gore Nest 2
</pre><pre id="faqspan-2">
This system of tunnels can be entered any time, except during combat. But
you'll probably want to do it right after Gore Nest 2.
It connects various stories of the Main Foundary Area overlooking Gore
Nest 2.
This is more of an exploratory area than a fight, but it is strewn with
minor demons.
It is hard to describe all the turns and the 3 entrances to this area, but
it can be explored easily enough. Just make sure you find:
* CODEX ENTRY "Monsters / Imp" in a dead-end room with some armor
* SECRET 3.4: To get to this secret area, you'll have to jump up to a
nondescript ledge. Look for a room with a rotating-red ceiling-mounted
light, over which is painted "UAC-HAL". Looking at that, the ledge is
slightly higher and to the right of it. Enter into it, and it'll twist
around to get to the secret and the ROCKET LAUNCHER.
There are three access points, all overlooking Gore Nest #2. Here's a
description of each of them:
* Lower Entrance / Gore Nest #2 Access
* From the vicinity of Gore Nest #2: looking out to the main area,
the catwalks on the right should have two stories. Get to the
upper story, and you'll find a small doorway.
* From the tunnel, look for blood streams and an obvious exit.
* Middle Entrance
* From the tunnel: look for an observation room; the door it
outside the window looking in.
* Upper Entrance / Yellow Keycard Guy Access
* From the guy: go out to a downward staircase; at its bottom turn
into a small door.
* From Tunnel: look for a green-lit room with 2 large white boxes.
Stand on the box(es) and jump to a yellow patterned ledge.
Mission 3: Fight: Obtaining the Yellow Keycard
To get here, go out of the Field Drone area, and go straight veering
around the Blue Keycard Area. Before you enter, you may see some Plasma
Ammo.
4 Imps, a Possessed Security and two Possessed Soldiers in back are ready
to fight you. The Shielded guy is the biggest problem, and the chainsaw
may be the most effective way to deal with him.
Taking the Keycard creates a CHECKPOINT.
Mission 3: Fight: Getting Away with the Yellow Keycard
Exiting the area triggers the creation of 2 Imps, a Hell Knight, and (down
the hall) 2 Possessed Securities. I usually run to the Field Drone
location, lobbing a grenade behind me. The Hell Knight is the only big
problem - in fact, often the other attackers will fight themselves to
nothing if you merely wait.
Mission 3: Fight: Argent Cell
In order to use the Yellow Keycard, you'll have to find a mishmash of
demons in a hot foundry area. The barrels provide an easy way to kill them
en masse.
ARGENT CELL 3.1 is found in the corner, in front of a defunct door.
SECRET 3.3 is the classic doom level. From the yellow keycard area, look
back on the walkway you came in on. There should be a box/crate on its
right side. On the side of that is a Lever, which will open a door in the
fight area that enters CLASSIC MAP 3.1 "Doom - Nuclear Plant".
Mission 3: Using the Yellow Keycard
As you approach the yellow keycard door, a Hell Knight will surprise you.
Entering the door creates a CHECKPOINT, so it is advisable to stock up on
ammo, armor and health before entering.
Mission 3: Fight: Hall after Yellow Keycard, before Gore Nest 3
After picking up whatever supplies from the anteroom, including CODEX
ENTRY, "UAC Personnel / Samuel Hayden", enter a hall where some repair
robots appear to be working on a crate.
Initially there are just two Possessed Soldiers (on the left-hand side) If
you stay near the entrance wall, nobody else will spawn, and it is
suggested to kill these guys before charging in.
Then, a Hell Knight, a (few?) Imps, an a few Hell Razers will spawn.
Lobbing a grenade at the barrel can help, but the Hell Knight has to be
dealt with.
SECRET 3.5, COLLECTIBLE 3.1, "Plasma Rifle Model, Prototypeguy" can be
found in a crate being robotically worked on (climb on top of it then
inside).
SECRET 3.2, ELITE GUARD 3.2, can be found by climbing crates at the back
of the room. There should be a chainsaw resting against the crates
(initially).
Mission 3: Fight: Gore Nest 3
A Possessed Soldier and Possessed Engineer constitute the pre-fight for
this Gore Nest.
Destroy the Gore Nest.
A few Imps and a few Hell Razers will spawn, and the finale is a Hell
Knight.
Mission 3: Finding the Blue Keycard
The map should probably show the Auto-Map - it's on the catwalk area.
Exit through the upper down in this area and you'll immediately run into
the Blue Keycard holder (a corpse). Take the keycard.
At this point, 2 Hell Knights will spawn far away. First is back at the
door you opened with the yellow keycard. He is quiet and may surprise you.
The second Hell Knight spawns near the field drone at the beginning of the
level. (These will not respawn if you die.)
Drop down to the area where you "found" the Yellow Keycard. This is a good
time to get SECRET 3.6, COLLECTIBLE 3.2, "Possessed Engineer Model,
Vaultguy". Look for the 3 streams of molten metal. Get onto the walkway in
front of them, and look straight down to see a little landing just inches
above the molten metal. Jump onto this platform and look for the doll.
Mission 3: Fight: Gore Nest 4
There's no pre-fight: destroy the Gore Nest.
This two level area has a sheltered locker room on the lower floor, where
one Imp will spawn immediately but most of the demons (Imps and Possessed
Soldiers) spawn upstairs. Lob grenades or charge in - eventually they'll
come down the stairs, but slowly.
It ends with a Hell Knight - since there's Gas, a chainsaw is a good
approach.
The upper story has a Health Station.
Mission 3: Once all four Gore Nests are destroyed
You may be ambushed by some Imps as you find your way to the waypoint.
The Turbine Room door, which the game will guide you to, is now unlocked.
CHECKPOINT.
Mission 3: Fight: Turbine Room
This fight has two waves, both start with a lot of Imps and Hell Razers.
At the end of the first wave is 1 Hell Knight; the second wave ends with 2
Hell Knights. The waves are separated by a little earthquake.
After completing the fight, exit at the top of the room, on the opposite
side as the entrance.
Mission 3: End of Mission
You come into a hall with ELITE GUARD 3.3 propped up on the left side.
Open the Shutters (interact with the screen), to watch a cut-scene with
Olivia Pierce.
Immediately after that, an Imp and 2 The Possesseds will spawn. (You could
get one more Heat Blast multikill here)
Mission 4: Argent Facility "Beginning of the End"
This area will be revisited in Mission 6: Argent Facility (Destroyed),
which mostly shares the outdoor areas, but the indoor areas are completely
separate.
Notes on Combat Challenges:
* Walk the Path and Bird's Eye View: easy with this walkthrough,
hopefully.
* To Be Knighted: glory kills from above on these guys is pretty hard
since they are so tall: unless you are replaying this with the jump
boots, you'll have to jump from higher ground to do this. The Dazed
and Confused rune can be useful to give you more time to figure out
how to jump over them - it usually requires jumping from above, unless
they are crouched. Of course, a cheesy way is to replay this mission
after you have the Jump Boots which make it substatially easier.
* Bird's Eye View: See Secret 4.1 below
Mission 4: Introduction
Go forward and Open the Airlock to find yourself in an industrial open-air
area: immediately in front of you is a trash fire and ahead of you is a
blocked-off bridge.
Look left. There should be a octagonal structure with 2 Platforms, a Lower
one and an Upper one. Jump to the Lower Platform. Now, look left for some
green marker lights on the cliff-like rocks. Jump up a few of them (follow
the green marker lights), and on to the Upper Platform.
Now, look for an broken bridge - jump there and cross another small
bridge, to your first Rune Challenge, RUNE CHALLENGE 4.1: "Vacuum". This
challenge is not too bad, and the rewards are quite good, so you should do
it. Time is really of the essence on this challenge.
After succeeding at the Rune Challenge, the Rune is NOT automatically
equipped, so go to the Rune section of your Dossier and select the Vacuum
Rune.
If you want, grab the ammo on the right pathway, but the mission continues
to the left.
In front of a closed door, you'll see some Health and Ammo, and CODEX
ENTRY "Environments / Argent Facility". Less obviously, behind some
barrels to the left, is a Classic Doom Level Lever - the lever is in the
dark and hard to see. Pull it: the "retro" level itself will be easy to
see ahead.
Mission 4: Fight: Gore Hallway
Enter the automated door to a hallway that has been thoroughly decorated
with entrails. Midway down this hall, to your right, is (assuming you
pulled the lever above) the SECRET 4.5, CLASSIC MAP 4.1 "Doom - Toxin
Refinery".
Continue out the hall to run into 2 Possessed Securities and a bunch of
The Possesseds. Some Imps will spawn soon; once you kill them you'll get
more Imps and a Hell Knight.
You can retreat into Hall (and it can be a good way to start the fight,
say, with a few Grenades). But the new monsters will start to spawn behind
you, and it may be easier just to stay in the open.
CHECKPOINT.
Mission 4: Fight: Force-Field Gore Nest #1
Jump over a crude but wide blockade to get to a view of a big glowing
rectangular blue force-field. The gore nest is just behind it.
Looking down, you may see some Imps fighting - they will see you soon
enough. Kill these few Imps, along with the Possessed Engineers and The
Possesseds stumbling around.
Destroy the Gore Nest.
You'll have to deal with 2 Hell Knights, 2 Hell Razers, and a bunch of
Imps.
CHECKPOINT.
It's probably worth going back to the Blockade you entered from, and look
around for a cave (it'll be on the left as you walk toward the Force
Field). The cave has ELITE GUARD 4.1. There's some ammo (etc) here.
Mission 4: Fight: Argent Cell
(It might seem logical to destroy the Argent Filter associated with the
Gore Nest first, but due to how the Checkpoints work, I suggest doing
things in this order)
You can now go and destroy the Argent Filter, but I think it makes sense
to first deal with the Argent Cell.
The Argent Cell is in the building on the left side of the force-field
when looking at it - on the opposite side of the gore nest from where you
entered. There should be some Health in front of it.
Entering, there will above 5 Imps spawned gradually.
Once they are gone, CHECKPOINT.
Now, find ARGENT CELL 4.1 behind some tanks. Use it: most players will opt
for Health.
Mission 4: Argent Filter associated with Gore Nest #1
Open the small door on the lower floor near the Gore Nest's old location.
Enter to find a Possessed Engineer and a few The Possesseds. There is also
CODEX ENTRY "Personnel / VEGA". Make a left to follow the waypoint and
interact with the Argent Filter for a cut scene.
Mission 4: Under the Force Field (Optional)
There's a small treasure area directly below the big blue force field.
Face it, and go left down a path (which has a Munitions Crate). Turn right
and descend 3 floating Islands of rock to get to a partially open bay door
(visible from above).
Inside you'll find Gas, shotgun and plasma ammo, and a little armor. But
most importantly FIELD DRONE 4.1.
Mission 4: Fight: Tank Gore Nest #2
Near the entrance for the Argent Cell building, find two stacked crates,
and a suspended one: these can be climbed, and from the top of the
suspended crate, you can jump to the second floor of this building.
This battlefield is distinguished by a recognizable and large Union
Aerospace tank (which you can jump on).
Pre-Fight: 3 Imps run down from above very quickly, be prepared to take
care of them.
Fight: Imps and Hell Razers with 2 Hell Knights.
Mission 4: Argent Filter associated with Gore Nest #2
Go into the closest door to Gore Nest 2, on its same level - it is
somewhat inset - a waypoint should be leading in this general direction.
Inside the building, go along the walkway to a closed green door with the
waypoint behind it by 15 meters. Enter and interact to destroy the Argent
Filter #2 and get a CHECKPOINT.
There is also a Plasma Rifle here.
Mission 4: Rune and Secret
From the small room containing the Argent Filter, turn right to a large
floor with large lifts. You can probably see the glowing green RUNE
CHALLENGE 4.2: "Dazed and Confused" on the lift in the opposite corner of
the building (from the entrance, look at the opposite corner - the rune is
on the structure just to the right of center).
Once done with the rune, look for a large hole that is serviced by a lift
(now down). Jump down there, and into a hallway. On the left you should
see a small block on a larger block, making a natural stairway. (A drone
delivers it- wait a few seconds if the blocks aren't climbable - or you
might have to go back to the argent filter you destroyed to trigger it)
Climb up, and turn right to see a service walkway which you can jump onto
to find SECRET 4.2, COLLECTIBLE 4.1, "Hell Knight Model, UACguy".
Mission 4: Back Access Walkway (Secrets, Optional)
This lonely walkway is the only dirt path descending from Gore Nest #2 /
Union Aerospace Tank. It provides alternate accesses to a Lab and the icy
Gore Nest #3; these are described below. It has a broken bridge midway.
If you face the Union Aerospace text on the large tank, go down the dirt
walkway to its left. It is the only dirt walkway descending from this area
- it'll turn to a metal grated walkway - then there's a gap you must jump.
Before the metal grated walkway, look to your right for a misty cargo
alcove with a lone crate. Jump on it to get to the second level.
You should find a Munitions Crate here.
A single Imp will pop out if you follow the walkway to its end.
If you stand on the platform at the edge of building, you should see a
rectangular duct that runs along the outside of the structure. Walk on it
for a bit until you get to the next alcove: enter to find SECRET 4.3,
COLLECTIBLE 4.2, "Rocket Launcher Model, Stealthguy".
Go back to the first alcove, but jump across to a green-lit cliff; jump
again to a walkway and kill a few demons (a Possessed Engineer and a few
Possesseds). (This is helpful to get the maximum combat rating)
Finally, go to the end of the walkway (it becomes a catwalk) to a door
(entrance to the Icy Area). Watch out for the Imp! At the end, go left
onto a natural walkway. This is SECRET 4.4. There's a Possessed Engineer
and a few Possesseds, but most importantly, the SUPER SHOTGUN.
Mission 4: Lower Area with Elite Guard #3
Start at the Force Field (Gore Nest #1) - when facing the field, go down
the path to the left.
You should see an active door, and a series of plateaus that lead to a
Munitions Crate. Immediately to the right of that is a level path that
becomes a sidewalk for a building. Some Possesseds appear here. At the end
of the walkway is ELITE GUARD 4.3.
Mission 4: Fight: Lab (Optional)
This area has a Health Station, FIELD DRONE 4.2, Gas, and CODEX ENTRY
"Monsters / Hell Razer", but isn't necessary to the completion of the
Mission.
Field Drone #2 is on the upper level - it can sometimes take a few seconds
to fly in once combat is over.
It has two entrances:
* Normal: From the site of Gore Nest #2 / the Union Aerospace Tank,
climb a crate to a balcony. The door enters the middle story of the
Lab.
* Sneaky: From the site of Gore Nest #2, walk down a dirt path to an
enclosure with some blocks on your right. If you look up, you should
see a greenlit ledge to your left, which is your goal. Climb onto the
blocks, at right, then onto a grating looking onto the greenlit cliff.
Jump across and open the door to be in the lower story of the Lab.
The Possessed Guards tend to be in the lower story and entering there
catches them more unawares, maybe.
There are also 5? Imps and a bunch of Possesseds and Possessed Engineers.
You'll get a CHECKPOINT when the bad guys are cleared.
Mission 4: Fight: Icy Gore Nest #3
There are 3 entrances to this area:
* Lower Entrance: from Gore Nest 2 (the Union Aerospace tank), go down a
dirt path to where it becomes a catwalk instead, to the end at a
active motion-sensing door.
* Mid-Lower Entrance: This is probably the "main entrance". From the
blue force field, go on the path on its left side to a building
labelled in large letters "COOLING TOWER".
* Upper Entrance: Access from the long curved exterior walkway with
Elite Guard #2.
It matters little.
Prefight: you'll have to deal with 5? Imps and 2? Possessed Soldiers and a
bunch of The Possesseds.
SECRET 4.1: You can actually use this area at any time.
It is the through the door on the lowest floor area. There's the Auto-Map
in here, and it'll CHECKPOINT. Of course, the Auto-Map achieves the
"Bird's Eye View" Combat Challenge.
Fight: Once the Gore's Nest is destroyed, 1 Hell Knight spawns immediately
along with a wave of Hell Razers and Imps. There's Gas on the second level
(and other supplies) in case you want to chainsaw anyone.
Post-Fight: Now, go in to destroy the Argent Filter.
There's a Munitions Crate, Gas??, a Health Station, CODEX ENTRY "Monsters
/ Hell Knight". Destroy the Argent Filter and go outside for the last
battle in this icy area.
Mission 4: Fight: Destroying the Icy Argent Filter
This is your introduction to the Summoner. She will spawn centrally the
instant you exit the control booth. The Rocket Launcher (especially with
Lock-On) is a nice approach, as is the Chainsaw, but she can really be
killed by any weapon.
Besides her, there are 3? Imps and a Hell Razer, making this an otherwise
small fight.
CHECKPOINT.
I recommend leaving the building through the top exit, above the Auto-Map.
You'll be on a walkaround that going alongside the building, a few
Possesseds and a Hell Razer will surprise you be spawning in front of you.
At the end of this walkway, find ELITE GUARD 4.2.
Mission 4: After Destroying the 3 Argent Filters
A new Gore Nest will appear: it's on the upper story and easily visible.
You have to get to it from the building below, which once housed ARgent
Filter #2.
Climb the crates, following the waypoint to the upper-story of the huge
hangar, right next to Rune #2.
Exit the door toward the waypoint (approx 80m away), stocking up first if
necessary and possible. There should be a Munitions Crate ahead, and to
the left is the exit to the Gore Nest.
Mission 4: Fight: Final Gore Nest
Pre-Fight: there are 2 Possessed Soldiers, a Hell Razer, and an Imp.
Destroy the Nest.
Fight: a Hell Knight and a Summoner are the main act in this fight -
there's also a few Imps and Hell Razers. However, there's a Berserk
Powerup, which compensates a lot (in fact, if you have all the Powerups
for the Praetor Suit, you can probably kill everything with that single
Berserk Powerup).
Mission 4: Destroy Primary Argent Filter
Enter the building and face left for ELITE GUARD 4.4.
Follow the waypoint to another Argent Filter (looks like the others).
Destroy it, and watch the cut-scene.
Follow the waypoint and Exit the Facility.
Mission 5: Argent Energy Tower "Argent Tower"
We start the level getting new Jumping abilities, the Jump Boots. Then we
cross a damaged bridge to the Tower itself.
The tower is big and tall - most of the level is spent ascending it.
Notes on Combat Challenges:
* Chiropractor: Imps are a bit scarce in convenient locations. There are
a lot on the bridge, but you'll have to be slightly patient to lure
them into Glory Kill range, and even then sometimes they'll be at the
back of a platform and it's not possible to get behind them. (Use the
Dazed and Confused Rune whenever you are attempting this challenge).
There are a number in the fight outside the tower, including 4 near the
entrance to the fight (and checkpoint). There are a few in the first big
fight, and there's 4 scattered at the upper regions of the tower. Finally,
there's some in the giant fight at the end of the level.
* Searching High and Low: easy.
* Overkiller: there are 3 Quad Damage Powerups: in the fight just
outside the tower, in the fight in the base of the tower, and in the
truncated big fight at the end of the mission. It is quite possible to
achieve this in any of those fights: as long as you use the powerup
you'll probably be fine. I recommend Plasma Gun/Heat Blast for bulk
killing.
Mission 5: Fight: Intro to Level, and Revenants
You start on a useless platform, and have to jump left to get to the
Maintenance Hangar that VEGA alludes to. Upon entering the building, look
right, and you can see a Revenant eating a corpse. It soon comes down to
attack you. There are a gaggle of demons on the floor below you, and more
will spawn when you drop down to the lower level (as you must to get to
the locker room with the needed boots). In total, there's about 3
Possessed Soldiers, 3 Hell Razers, 3 Possessed Engineers. (No Imps,
unfortunately, as it would help with the Chiropracter challenge.)
Mission 5: Maintenance Hanger miscellany
Enter the locker room and retrieve the Jump Boots, as well as CODEX ENTRY
"Environments / Argent Energy Tower", various Ammo, and a Health Station.
Exiting the locker room, go right (back toward the entrance) and
double-jump up onto a platform; U-turn and look left for another platform
to up-jump. Then down-jump into an enclosed area with a Rune Challenge
(which was visible from before through some steamy glass), a suit of
armor, and Gas can. To exit this area, jump down.
Jump up the same platforms used to access the RUNE CHALLENGE 5.1 "Ammo
Boost", but look across the area for a floor you can jump to, under a
low-beam; some armor is at the end of the jump. To the right is a crate
and some rockets, but ignore them for now, and go left. There is a
platform to jump up on, and if you look around, you'll see another
green-lit platform above to jump on. Looking around from the top platform,
you should see a pink-lit short alcove that you can drop into: there's
SECRET 5.1, ARGENT CELL 5.1 here.
Hints on Rune Challenge, "Ammo Boost". The challenge is to not miss anyone
- I find that I jump make 1 1/4 laps around the periphery of the area,
looking into the center to shoot any stragglers.
Ammo Boost isn't exactly necessary, but it (and its upgrade) make ammo
much more available - especially BFG ammo, once you have the Upgrade and
of course the BFG itself.
Mission 5: Crossing the Bridge, and Secret Guardhouse
Before crossing: make sure you have Argent Cell #1 and Rune Challenge #1.
The bridge starts with a crate and some Rockets. Use the crates to jump
left onto the bridge proper. Continue along. You'll jump down to a
platform.
At this point, you can expect to be ambushed by ~8 Imps, 2 at a time. They
are all over this gigantic damaged catwalk bridge, you can kill them,
ideally by Glory Killing them from behind, to work on achieving the
Chiropracter Challenge.
From the tunnels, you can and should access FIELD DRONE 5.1 and a SECRET
5.2. Get on top of either tunnel, and double-jump across to a platform (it
has a green light). Jump left up a series of airy platforms to an enclosed
bluish area with 8 The Possessed stumbling about with a Possessed Engineer
on the upper deck (near a suit of armor). Right outside (on a bridge) is a
Possessed Security.
Across the bridge is a guard house, which is Secret #2. Inside is a Hell
Knight who will charge at you; and 2 Possessed Soldiers and a Possessed
Security who will stay in the shed. Take them out to find Field Drone #1,
some health, CODEX ENTRY "Monsters / Revenant". Continue along a walkway
to some armor.
When done, jump down to a long walkway that goes almost the whole length
of the bridge. There's a long gap torn in the walkway: you'll have to
double-jump across (which is slightly hard to backtrack).
Mission 5: The Far Side of the Bridge
After the destroyed section of the bridge, look down and right to see
ELITE GUARD 5.1 (SECRET 5.3) propped up against a wall. Jump down. Getting
back up is slightly more difficult: jump across the gap to jump nearly
vertically up a few ledges, looking for yellow ledges; you'll have to
shimmy left at some point.
Note: You can get back, but it's not necessary and more difficult than
jumping forward.
Cut scene.
Enter the next room to find a Health Station, CODEX ENTRY "Monsters /
Summoner", and an AUTO-MAP.
Mission 5: Fight: Tower Exterior
Enter the next area to surprise 2 Imps. Looking at the Imps, there's some
Plasma ammo to your left. Ahead, the platform has an upper outer story and
a lower inner story. Further ahead, on a higher platform, is a Quad
Powerup - it glows purple brightly.
It's fairly easy to get a Neck Glory Kill on an Imp, then grab the Quad
Powerup and use Plasma Gun / Heat Blast to kill basically everything.
The monsters who are here or will spawn are many Imps and Hell Razers, and
2 Summoners.
Leave this area through a Maintenance door on the far end.
Mission 5: Lower Railway (Description and Secret)
As you can probably see by the Map (in the Dossier), you are at the
outside of the tall circular Argent Energy Tower. Unmanned trains run
around it's exterior, and you'll encounter them a few times.
You should see such an unmanned train going right every 5 seconds or so.
Use the Munitions Crate, then follow the next convenient train, and drop
into an unused track. Keep going, and you should see an entrance to a
human-sized passageway on your left.
Upon entering the passageway, look back to find ELITE GUARD 5.2. Continue
to find a Health Station and Codex Page "Database / Argent Energy".
At some point, the passage becomes narrower and darker, and we can make a
detour to get the Collectible doll.
To get SECRET 5.4, COLLECTIBLE 5.1: "UAC Pistol Model / Orangeguy",
re-enter the unused Train corridor at this point (by veering right).
Continuing down the corridor, you'll arrive at an unused, stationary train
car. Get onto it, by double-jumping onto the ledge to your right, then
double-jumping onto the train car (don't worry: the upper-train won't hit
you). You should be able to see another dimly-lit ledge near where the
upper train cars keep entering. I found this jump to be quite tricky. but
the trick is that you must be facing at the ledge (ie facing perpendicular
to it / straight at it), which mean you must jump almost sideways, which
in turn makes dodging the train above more difficult. Once you are on this
ledge, turn left and go up (parallel to train), then turn around and jump
into the hole that the upper train is entering. You must keep moving, but
when you run out of floor, drop to the left, and you'll find the Model.
Drop down the train area to get back to the Elite Guard, and continue back
to where the passage narrows and becomes darker.
OK, continue down this short dingy corridor, and you'll find a Hatch, at
left, along with some a rocket launcher.
POINT OF NO RETURN: Dropping down this hatch is irreversible, and a
CHECKPOINT is created immediately on hitting the ground.
Mission 5: Fight: Base of Tower
This fight begins with a cut-scene introducing us (somewhat) to the
MANCUBUS.
Use the Rocket Launcher or Gauss Cannon (etc) to damage this guy before
running around for a while taking pot-shots at various demons.
Once you damage a lot of demons, look for the Yellow Lift that jams you
into a Qad Powerup. Use Plasma Rifle's Heat Blast to kill a lot of demons.
Post-Fight: pick up all the Gas and Ammo.
Midway up there's a tricky little secret. You'll find it after where the
central red beam (of Argent Energy) is surrounded by rotating and
stridulating metal shields.
Continue up, across a long jump to where the red beam is protected by
shutters that periodically open and close. Look on the map. You should see
two symmetric arms going up. But one of them has a walkway underneath.
This is SECRET 5.5, COLLECTIBLE 5.2 with "Summoner Model, Purpleguy". With
the In-Flight Mobility Rune, this is a piece of cake, but you don't have
that yet, so you'll have to use one of two approaches.
* You can actually jump on the gray tubes that run to the platform, then
jump again onto the platform.
* Drop from a platform above, and jump in mid-air onto the duct.
Resume climbing: there's a rotating train that repetitively inserts ducts
into the central beam. Between when it opens and when it extends the duct,
you can jump up.
Mission 5: Fight: Midway
A fight involving Possessed Soldiers, Imps, Revenants and a Hell Knight
breaks out here. There's a somewhat tricky-to-get-to Invulnerability
Powerup that can help. It can found be looking for the two protected doors
a few stories up from the ground level. One is your waypoint (it has a
suit of armor in front) and the over has the green Invulnerability
Powerup. Use the blue lifts to get onto this high area.
After the lockdown is disengaged, continue up to where the waypoint is.
Mission 5: Activating the Drones
Use ARGENT CELL 5.2 and the Health Station if needed, and interact with
the screen (at waypoint): "Activate Drones".
This will cause two pairs of cars (drones) to transport stuff vertically
from this area to a platform above: we'll catch a lift.
Exit the control room and find that there's one pair of drones right in
front of you.
Instead, go around to the opposite side of the column where the second
pair of drones is (this is also where the Invulnerability Powerup is).
(These drones are illuminated in blue; the drones near the control room
are green) Jump onto a drone and go up: you'll see a platform at the top,
with (if you look carefully) a lever. Jump to it and actuate the Lever.
Hitch a ride down with the drone. At the bottom, the drone will plug into
a socket; when it disengages, you'll see SECRET 5.7, the CLASSIC MAP 5.1
"Doom - Halls of the Damned" in the back of the socket.
After that, take any drone up to the top and jump up to the highest
platform you can. You'll see another rotating plug train. When it stops
you should be able to jump straight onto it. When it stops again, follow
the plug and some on to a platform on either side.
From this narrow inner circular walkway, you'll see 4 arms ascending to
the outer side of the tower. One of them has a couple of platforms by its
end: you'll have to take that one, and jump up a few platforms.
Keep going up, steering clear of the argent beams and taking out 4 Imps.
Eventually you can hitch a ride up on one of the argent transfer things.
From the top, the waypoint is right there: a greenlit door to force open.
Mission 5: Fight: Upper Office
2 Possessed Solders and a bunch of The Possessed await you inside.
From the office, take the stairs to a Possessed Security, a Hell Knight,
and a few more minor demons. The passage comes to a dead end.
Mission 5: Ascending to the Top
From the dead end, you can jump across the tracks through a "window". To
your left will be Rune Challenge #2, "Equipment Power".
"Equipment Power" is a pretty easy and fun challenge. Simply use yourself
as bait to lure the Unwilling into barrels that you shoot. Watch out for
Unwilling that spawn behind you though!
After the Rune Challenge, look back across where you jumped the tracks,
and notice a higher platform you can jump to.
You come to a pair of elevator shafts. The first one (on the left) has a
Munitions Crate in plain view. The second one has a Mega-Health down in
the shaft. Drop down to get it, and retrace your steps.
From the Munitions Crate, jump onto an obvious ledge system to another
hallway.
Before going on, look at the twin elevator shafts. Between them, in the
hall is a wide brown pillar with orange lettering on it ("UAC E-1" on one
side, "U-A 46.2" on the other). There's a landing in back between the two
elevators: ELITE GUARD 5.3 is here.
Continue up the stairs and through the door to another elevator shaft on
left, and audio of Olivia.
Carefully peer down the elevator shaft - you'll see an opening about 6
lights down: jump and hold forward to land in it - this is SECRET 5.6.
Here we acquire the GAUSS CANNON, the most powerful "standard" weapon.
"Open the Turbine" by interacting with the screen, which will open a exit
from the shaft.
Take it, and retrace your steps all the way back up to the top of the
shaft. Note there's a Hologram (sometimes known as a Decoy) and a Plasma
Gun here.
Now, jump up to the landing at the far side of the shaft and look at the
shaft ceiling to see 4 red glowing things - each with a waypoint on it.
Shoot them to cause a car to fall exposing another higher landing you can
jump to.
Mission 5: Pseudo-Fight: Before the Countdown Ends
You could conceivably use this to do some Weapon Upgrade Challenges or
Rune Challenges, but I usually focus on trying to conserve my 200/200
which means perservering for a long time, then taking the Invulnerability
Powerup at some point.
Another use is to earn Combat Challenge progress. If you killed everything
else, you should already have the highest Combat rating, but you can get
just about a full circle if you fight very aggressively here.
TODO: Timings
Mission 6: Kadingir Sanctum "Into the Fire"
Notes on Combat Challenges:
* Dead Man Stalking: these guys can be easy to miss.
* Momentum Swing: fairly easy if you use all the powerups (just don't
"save" them for too long).
* Sweep the Leg: there's not a huge number of these guys in convenient
locations, and the glory kill is a bit hard to execute anyways. Don't
miss any opportunities!
Mission 6: Fight: To get the Yellow Skull
Because there are no Checkpoints, this sequence of fights is gathered
together.
First, drop down to a plateau with a toxic pond and 3 The Possesseds -
target-practice. There's some armor. Jumping across to Plasma Ammo, maybe
a Gauss Cannon.
Climb up the stairs and kill 3 The Possesseds.
This is one opportunity to get SECRET 6.4: after killing The Possesseds,
look up and to your left for a rock ledge you can jump onto, then a
sequence of 2 more ledges to get a suit of Armor.
Venturing out will begin the pre-fight; the main fight won't begin until
you get near the left edge.
Look down to the next lower platform and you'll see an Imp spawn: you can
kill it immediately with a grenade. Then a Revenant spawns: I usually use
the rocket launcher, but whatever works.
Stand on ledge that has a suit of armor on it. Look down below into the
Main Pit Area, and soon you'll see 2 Mancubi lumbering around that you can
carefully attack with the Rocket Launcher (preferably with Lock-On
modification).
Quickly jump down the Pit area, to trigger two waves:
* a bunch of Imps and a Hell Razer, ending with a Hell Knight
* a bunch of Imps and a few Hell Razers, ending with 2 Hell Knights
Mission 6: Accessing and Using the Yellow Skull
The game's waypoint will lead you to a switch (only accessible once all
the above demons are killed). After actuating the switch, walk across the
pit to a newly opened area with armor and the Yellow Skull.
Now, find the Yellow Skull Door, by walking up the path from where the
last fight started. Open the Door to walk in and find CODEX ENTRY
"Artifacts / Slayer's Testament #1" and ELITE GUARD 6.1.
Proceed onward to the next fight.
Mission 6: Fight: 2 Summomer Fight
This fight starts on a plateau overlooking another pit area with T-shaped
bridges running atop it.
If you enter but don't move, there are 3 The Possessed you can kill. Once
you walk out toward the middle of the level, 3 Imps spawn.
Once you get to the edge of the plateau is when the bulk of the demons
spawn. On the center of the bridge, a Summoner will spawn. Lock-On Rocket
Launcher is a good way to get her (as suggested by the Weapon Upgrade
challenge). Another Summoner spawns on the left side of the lower area.
2 Hell Knights soon spawn, along with a mess of Hell Razers (etc).
Mission 6: Getting the Blue Skull
Follow the game's marker to a Chainsaw and Shotgun Ammo. Continue down a
passage to watch a series of islands appear, in the large cavern where the
first fight began.
You can jump directly to the nearest island, or jump down and make
slightly easier jumps up the islands. (If you want armor, this is your
second chance to get SECRET 6.4: you can see the suit of armor from above:
climb the stairs and use some ledges to jump to it) In either event, a
Skull-Switch is at the top of the islands; pressing it, you'll see a gate
lift on the lower level. Jump down there, killing The Possesseds flailing
around.
The green mist will teleport you to the next area; before doing that, head
right to pick up supplies and SECRET 6.1, COLLECTIBLE 6.1: "Revenant
Model, Astroguy".
Head through the teleporter.
You'll find a Blue Skull. Upon taking it, a gate will open leading you
back to the overlook of the Main Pit Area.
Mission 6: Fight: Main Pit Area, part 2
Before you can do anything, 4 Imps will spawn up here.
Imps should start spawning below: carefully take them out with grenades or
whatever.
A few Cacodaemons will spawn. Two blasts with the Lock-On Rocket Launcher
will kill them, or you can target their eye with the Assault Rifle, or
Gauss Cannon works. You'll also need to keep lobbing grenades to kill the
Imps that like to hang out in the area to the right of the base of the
long stairs.
At some point, to trigger more demons, you'll have to descend to the
floor. Take the Quad Powerup as needed (if you have 2 Power Upgrades,
you'll refresh your health at this point, so it can be best to wait until
you are damaged. There is a wave of Revenants and a Hell Knight, another
Cacodaemon, more Revenants, a Mancubus, and a number of Imps.
Mission 6: Rune Challenge and Using the Blue Skull
POINT OF NO RETURN: This Rune Challenge is only accessible for a short
while. The protective gates around it are closed before you get the Blue
Skull, and after you pass through a holographic ritual taking place in a
corridor. (XXX: is the Rune accessible during the above Fight??)
Accessing RUNE CHALLENGE 6.1 requires jumping onto the central Rock that
held the Quad Powerup. Jump onto the smaller upper island (there are two:
jump toward the one closer to the Blue Door?). Then you should see a
man-made (or demon-made) ledge to your right, with a few small Healths.
Jump, and turn around and look up to see a higher island. Jump to it -
then continue the same direction to an upper ledge. Climb a short ledge to
a tunnel leading left to the Savagery Rune Challenge.
After finishing it, go back to the main rock (where the Quad Powerup was),
and jump to the "balcony" with the Blue Skull Door. Interact, and you'll
be in a pale green stone hallway: immediately on your right is an alcove
containing Gas and a ARGENT CELL 6.1. Further down, is rockets.
Mission 6: Fight: Misc Small Fights in the Cliff Area
First up, is 4 Unwilling (good Weapon Upgrade fodder for Super Shotgun or
Heat Blast) with a Mancubus, and a second Mancubus that jumps up when the
first dies.
Now is not a bad time to use the Invulnerability which is on a lower level
near where you exit the tunnel.
Walking along the ledge, some Imps, 2 Lost Souls, a Revenant spawn. (Kill
them while Invulnerable to work on the Momentum Swing challenge) (Another
good strategy here is to retreat and pick them off with the Assault Rifle.
Often they'll kill each other)
Island-Jump across to be surprised by 3 Lost Souls, and a Hell Razer (if
you haven't completed the Sweep the Leg challenge yet).
Walk through the tunnel behind the Hell Razer, and you'll be on a new
cliff, with a fire and ELITE GUARD 6.2. First, look left and down and
you'll see the first Cacodaemon. There is second one, probably behind that
rocky pinnacle. Lock-On Rocket Launcher is a fool-proof way to deal with
these guys.
(Do not forget to visit the Elite Guard)
Detour for SECRET 6.2: Jump to the Island with the Armor and jump across
to a lower ledge. Turn right, and a Hell Knight will spawn. Behind him (to
the left) is a small cave with the Chaingun (the cave is the secret).
Retrace your steps to the spent Elite Guard across the cavern.
Island-Hop using the upper chain of islands. At the end of this sequence
of 5? Islands is a Skull Switch: you will see the Iron Gate to the next
part of the level raise when you actuate it.
You won't get a CHECKPOINT until everything is cleared (except the Hell
Knight)- usually that occurs after the pair of Cacodaemons.
Mission 6: Fight: Second Pit
Enter to find yourself in yet another large arena centered around a "pit"
with bloody floors. To your left is a balcony from which you can deal with
a few demons, most notably 2 Lost Souls. There's a lot of Hell Razers,
Imps, and Revenants, as well as 2 Hell Knights and a Mancubus at the end
of the fight (the Mancubus only spawns as you approach the waypoint).
In the pit, there's a tunnel with many small armor and a Haste Powerup.
Mission 6: Rune Challenge: "Seek and Destroy"
After the fight a tunnel opens to the RUNE CHALLENGE 6.2.
Mission 6: Extracurricular Activities around the second pit
You can continue up the stairs for the main campaign path, or you can
return to the levels entrance and look for two small adjacent caves that
opened up.
The right-hand cave has a suit of armor and an Automap.
The left-hand cave has a green teleporter to a treasure room of sorts with
CODEX ENTRY "Artifacts / Slayer's Testament #2". You could teleport back,
but instead look for the exit corridor and find another CODEX ENTRY
"Environments / Kadingir Sanctum" and ELITE GUARD 6.3.
Finish the detour by following the corridor and using the yellow lift to
cross the chasm. If you go straight, then left, you should see the stairs
leading down to Rune Challenge #2 (and a suit of armor).
Descend the stairs about halfway (above the decorative gate) and look for
a ledge to the left you can jump onto to find SECRET 6.3, COLLECTIBLE 6.2:
"Mancubus Model, Redguy".
Back at the top of the stairs, find a FIELD DRONE 6.1 (now's time to get
the Gauss Cannon's Siege Mode) and CODEX ENTRY "Artifacts / Doom Marine".
A few stray small armor mark the top of a steep staircase. Descend it to
see a holographic replay of Dr Hayden and some guards.
POINT OF NO RETURN: Once you go through the gate ahead, you will no longer
to able to get back to the earlier parts of the level.
Pass through the gate (it'll open for you), into a fight scene.
Mission 6: Fight: Hell Barons in Arena with two Subarenas
The fight is already underway between the first Hell Baron and a bunch of
the Possessed and 6? Imps. By far, the Gauss Cannon in Siege Mode is the
easiest way to deal with the Hell Baron, then deal with the stragglers
however you want.
At some point, a Summoner appears. I usually use the Rocket Launcher, but
Gauss Cannon or even Chainsaw works.
Another Hell Baron and some Imps arrive.
After that's all gone 6? Lost Souls spawn. It is good to take shelter in
the more protected subarena and pick them off with the Assault Rifle or
Shotgun or whatever.
Finally, 2 Hell Barons spawn. I use the Quad Powerup and the Super
Shotgun. If you already used the Quad Powerup, just keep moving and
dodging their shots (they move fast, though) and use either the Gauss
Cannon (you need to move fast, so no Siege Mode) or Super Shotgun.
Mission 6: Onward, after a short Secret Detour
OK, go back to the large main arena from the last fight. There is a big
cave. Inside the cave (which can be a bit dark) is a lever: an Original
Doom Level trigger. The location of SECRET 6.6, CLASSIC MAP 6.1 "Doom -
Slough of Despair" itself is on the lower floor closer to where you
entered the arena, or simple walk off the ledge between the two subarenas,
and drop down.
Or use the map: it looks quite distinct with a visible arrow drawn into
the map in the Dossier. Once there, the arrow marks the correct switch to
press (ie the Left switch). It accesses a Mega Health Bonus (although
crudely rendered, it is just as effective as a modern-looking one).
Go back to the subarena that once held the Quad Powerup, and now should be
decorated with a glowing green circular symbol. When you approach the
door, it will open.
Mission 6: Fight: some small easy fights
First, there's about 6 Unwilling in this corridor. they are useful for
Weapon Upgrade Challenges (eg Tactical Scope, Heat Blast, Super Shotgun,
Pistol). And 2 Lost Souls to watch out for.
Instead of charging out island-hopping, turn right, and go up some stairs
to overlook a Mancubus and 2 Revenants fighting. Help them kill each other
with a suitable weapon (ie Rocket Launch or Gauss Cannon).
Go ahead and island-hop over to the largest platform which should have
some shotgun ammo. Turning left, 2 Cacodaemons will appear: kill them
(using e.g. the rocket launcher). Go to the edge where the Cacodaemons
appeared, and look across the chasm to see that a few islands connect you
to another dilapidated staircase across the way. Make your way over. The
landing hand a few small health, CODEX ENTRY "Monsters / Mancubus" and
Gas.
3 Unwilling and a Mancubus guard another tunnel: you should get a
Checkpoint here.
Continue up some stairs, to find 4 more Unwilling wandering around some
armor: good target fodder.
A CODEX ENTRY "Artifacts / Slayer's Testament #3" is found.
The last easy fight is about 5 Imps fighting 10 Unwilling. (I like to work
on the Savagery Rune and the Seek and Destroy Rune for this easy fight).
Don't miss ELITE GUARD 6.4 here! (to the left from the way you entered)
Enter a well-stocked tunnel ending with CODEX ENTRY "UAC Personnel /
Olivia Pierce" for a CHECKPOINT preceding the final fight of the mission.
Mission 6: Fight: Finale
It comes in unseparated waves:
* 4? Imps and 3? Hell Razers
* 2 Hell Knights
* 4 Revenants
* 3 Mancubi
* 2 Hell Barons and 1 Mancubus
I tend to save the Quad Powerup and for the end; get the Armor on the
toplevel (a sometimes overlooked location) early on to make it easier.
Keep on the move and kill quickly.
Walk up the hill to a holographic replay of some sort of ritual with a
casket.
Interact with the screen ??? to exit the level.
Mission 7: Argent Facility (Destroyed) "Hell on Mars"
Notes on Combat Challenges:
* Skeet Shot: Revenants fly into the air periodically to target you, and
so the challenge isn't so much shooting them as killing them (they can
take a lot of damage). Gauss Cannon/Siege Mode will reliably kill them
in one hit; Rocket Launcher/Lock-On will reliably kill them in two
hits. So these are my favorite weapons for this challenge.
* Close Encounters: there's a fair amount of gas in this level, but it
can be easy to forget to use the Chainsaw. Note that it can be best
just to mostly fulfill the challenge on some easier demons, since they
take much less fuel.
* Knowledge is Power: easy
Mission 7: Introduction
Pick up CODEX ENTRY "Monsters / Barons of Hell"
Go ahead and exit to the outdoor walkway, turning right (since left is
blocked by fire).
Mission 7: Fight: One Cacodaemon on Walkway
Be surprised by a Cacodaemon; it's a bit annoying on this narrow walkway-
with timing you can get it in one Gauss Siege Cannon, but one have space
to dodge it as well. (You can actually get the drop on it, if you are
prepared)
Mission 7: Getting back into Argent Facility
At the end of the walkway, turn around and look for a walkway to jump up
to. Next, jump across to a train and follow it to a small landing with two
tarp-covered crates. Behind these crates is a lever for the Original Doom
Level. After actuating the lever, drop down to another walkway/landing
with a grated floor, and turn around to see a large octagonal pillar with
a large "1" on it. Behind this pillar is SECRET 7.6, "Classic Level / Doom
2: Underhalls".
Immediately upon exiting this area, turn right, to see a right-dirt
floored alcove with some crates. There is SECRET 7.4, COLLECTIBLE 7.1,
"Cacodaemon Model / Rageguy". There's also some armor and Gas.
Now, jump your way up to the highest accessible walkway.
</pre><pre id="faqspan-3">
You'll get a CHECKPOINT shortly before a long double-jump. It's not really
difficult though. Continue until you are looking into a damaged corridor
which crosses the chasm.
Drop into the hallway through the gaping hole in its roof. Turn around to
find an ELITE GUARD 7.1 (along with some armor and shotgun ammo).
Go forward to the computer area. Find CODEX ENTRY "Environments / Argent
Facility".
Interact with the computer for a 48 second cut scene, whose immediate
consequence is that you need a yellow keycard. A marker will take you to
the airlock, which has a screen you can interact with.
Mission 7: Fight: Side Cargo Bay Exterior
While you may not see monsters immediately, they are just to the right: a
Hell Razer, a Possessed Engineer, and 6? The Possessed. You can take care
of many by shooting the barrel. Expect 2 more Revenants, Imps, Possessed
Soldiers, 2 Cacodaemons, and a Hell Knight.
Mission 7: Fight: Maintenance Exterior
Drop down to another former gore nest location, near the large Union
Aerospace tank, on a ground area with lots of fire, to get another small
fight with Imps, Hell Razers and a Hell Knight.
There is a Hologram device near some ammo.
Look down into the next area. This is the area that used to have a blue
Force Field, but now just has some fires. You should see the pale-orange
glow of a Berserk Powerup. Drop down.
Mission 7: Fight: Main Cargo Bay
First to appear will be 2 Cacodaemons and 1 Imp. One Cacodaemon often
starts very low and can be chainsawed to solve several problems at once.
After that, Imps, 3? Revenants, and a Summoner appear.
In fact, the Berserk may outlast the fight: you can perhaps even you it to
kill some stuff in an adjacent area.
Mission 7: Fight: Main Cargo Bay Adjacent: old platform area
This area is easily skipped.
There's a Hell Knight and a few Imps.
Mission 7: Fight: Main Cargo Bay Adjacent: through tunnel
This area is easily skipped.
A Hell Knight, a Hell Razer and at least 1 Imp.
This is the area that had the Lever for the classic doom secret in Mission
4.
Mission 7: Accessing Rune Challenge "In-Flight Mobility"
From the Old Platform Area, there's a blue lift that'll drop you on the
rock for this Rune, RUNE CHALLENGE 7.1.
Or, you can jump across from the cargo crates in front of the Security
Station Doors.
NOTE: This challenge is frustrating for many people, since it has little
margin for error. However, it is worth the practice, because the Rune is
critical for some of the bosses.
From this location, you can drop down SECRET 7.2 which has a Mega Health
and ELITE GUARD 7.2. Equip the In-Flight Mobility Rune (which you just
got). Go to the edge of the rock with the chasm and go to the edge of the
rock. Turn around so that so can drop backward off the rock and face into
it. Walk backward and fell to a cave, jumping forward right as you see it,
so that you'll land on the Mega Health. The Elite Guard is in the shaft
behind it. To get back, jump to a rock with a blue booster.
Mission 7: Fight: Security Station
To get here, from the Main Cargo Bay, look for a pile of 3 crates to climb
on. The door should have a marker on it (an in-game destination) and there
should be Gas here.
Entering, there's even more supplies littered throughout a gory hallway.
Interact with the door to get a short cut-scene introducing us to the
Pinky.
The fight begins with 2 Pinkies and at least 1 Possessed Soldier (and a
hard-to-count number of The Possessed in the peripheries- most of these
get killed by other demons!).
After killing those Pinkies, another wave of 4? Pinkies (etc) is
triggered.
After the fight, visit the Auto-Map, and get the CODEX ENTRY "UAC
Personnel / Dr Samuel Hayden 2".
There's also a Health Station here.
After triggering and watching a holographic replay, you'll be allowed out
the Security Station's second door.
Mission 7: Fight: Exiting Security Station
Opening the door, you'll see a Pinky: but there's actually 2 Pinkies. As
well as 2 Revenants, 2 Imps. You can use the Quad Power-Up but I usually
save it for the more tough fight coming up. Once you kill all these guys
you'll get a CHECKPOINT.
There's ELITE GUARD 7.3 on the top level.
Interact with the Munitions Crate in the far corner of the lower-level.
Unfortunately you'll need to re-do this each time you die: on the positive
side, this Munitions Crate refills between most battles.
Mission 7: Fight: Exiting Security Station and Entering ???
This fight is triggered when you take the stairs across the chasm after
killing everyone.
Initially there just a lot of The Possesseds staggering around, but a
Revenant, an Imp, and a Cacodaemon are the first wave of guests to this
party.
A second wave (somewhat indistinct), is another Revenant, Cacodaemon and a
few Imps.
The third wave is different: two Pinkies and a Mancubus. These guys come
out of the hangar ahead of you, and if you time it right, you can take
them out with a single satisfying Quad-Damage Siege Cannon on the bridge.
Mission 7: Fight: Indoor Gore Nest
Enter the building picking up health, Gas, Plasma, and CODEX ENTRY
"Monsters / Mancubus 3".
Almost the entire pre-fight can be handled with a single Gauss Cannon
Siege Mode shot. Except you may have to deal with a pernicious Hell Razer,
plus a lurking Possessed Security (use the Gauss Cannon on this fool, who
hides on the left as you approach the Nest).
Before destroying the Gore Nest:
* Consider taking the Megahealth Powerup on the crate above.
* You'll probably want to use your chainsaw, so find Gas where the
Possessed Security hides (to the left as you initially walk toward the
Gore Nest).
* The two Pinkies spawn in reliable locations, one near the entrance
* I usually retreat toward the entrance to minimize complications and
environmental risks: your mileage may vary.
In addition to 2 Pinkies, a Hell Knight and a few Hell Razers spawn.
The finale is a Hell Baron, who starts on the far side of the room (with
the Health Station and chainsaw). I like to use the chainsaw on it, but
the Gauss Cannon/Siege Mode is also quite effective.
Mission 7: Post-Fight ??? Cleanup
Pickup all you can.
There should be a screen prompting "Reset Crane to Base?" to access near
the bridge over the electrically charged floor. Actuating the Crane will
cause a large suspended block to move within jumping range. Jump onto it,
then jump right onto a catwalk. This is SECRET 7.5: access FIELD DRONE 7.1
at the end of the U-shaped catwalk. (I tend to choose Chain Gun / Mobile
Turret here.)
Exit through the door near the Health Station.
Mission 7: Accessing Rune Challenge: Armored Offensive
Exit the building and turn left, killing an Imp and Revenant.
Jump across to the right and follow the walkway to the end to find RUNE
CHALLENGE 7.2 "Armored Offensive" (which is also SECRET 7.3).
This is a useful Rune for hard fights, since getting more armor is the
same as more health, for the most part.
Now, turn around, and run back toward the waypoint. To the left you'll
find a Munitions Crate on a plateau. Often there are The Possesseds
stumbling around and even a Cacodaemon at times. After killing all that,
you should find a CHECKPOINT.
Mission 7: Fight: Upper Gore Nest
Continue along the ledge, jumping around to the green-lit ledges. At the
top, you'll find an airship with some loot - including CODEX ENTRY
"Monsters / Cacodaemon", a Hell Knight, a few Imps, and a bunch of
Possessed worshipping the Nest.
Kill the Hell Knight and the Imps, and use the Possesseds for target
practice.
When ready, destroy the Gore Nest.
Immediately a Hell Knight will spawn behind you, and some Imps and Hell
Razers.
There will be 3 Cacodaemons and 3 Revenants over the course of the battle
as well.
Toward the end of the battle, a Mancubus will emerge.
Use the Haste Powerup in the corner whenever you need a boost: this fight
isn't too tough.
Mission 7: Post Upper Gore Nest
ARGENT CELL 7.1: Looking back the way you came, you should see a plateau
at your elevation: it is easy to get to. Once there, look down at see the
Argent Cell: drop down to it and choose your powerup.
Go back to the site of the Gore Nest, and enter the door.
There is a Pinkie Corpse holding the Yellow Guard Corpse. You can interact
with it to get the Keycard.
There's also a secret here. Look up for a bloody ledge in the ceiling at
the left of the room on entry. Find SECRET 7.1, COLLECTIBLE 7.2, "Baron of
Hell Model, Patriotguy".
Return to get the Yellow Keycard, watch the holographic replay, and use
the Yellow Door.
Drop down the elevator shaft. Before exiting the obvious way, turn around
and look up to find a square duct: jump into it and find ELITE GUARD 7.4.
Exit the elevator shaft: you should recognize this as the site of an
earlier Gore Nest battle. Make a hairpin turn to the right and go in the
Yellow Keycard Door.
Mission 7: Fight: Tram Access
A few Possessed Soldiers and a number of The Possessed lurk here, useful
for some Weapon Upgrade tasks. When ready, interact with the Tram Console
to "Resume Route" to finish the level.
Mission 8: Advanced Resource Complex "A Brighter Tomorrow"
Notes on Combat Challenges:
* Bottle Opener: quite easy as there's a lot of The Possesseds wandering
around in non-threatening situations
* Double Take: watch out! you can't do this in replay if you miss a
Rune!
* Hide and Seek: easy
Mission 8: Introductory Lobby (with small Fight)
Enter a large lobby area, finding a Mancubus killing some The Possesseds.
After killing these, look for a pair of restrooms. There's a GAS CAN in
the main hallway. (In the Men's Restroom is some armor you can save for
later maybe.)
In the Woman's Restroom is a hatch allowing access to a secret area. Climb
onto the sinks and look around for the bloody hatch: jump to it and follow
the duct (there's another GAS CAN) to drop into a room (SECRET 8.7) with
an Auto-Map and an ELITE GUARD 8.1. The screen next to the door will open
it.
After exiting the Secret Room, you'll enter a Security Area with 6? The
Possesseds, a Health Station, an ARGENT CELL 8.1, a Plasma Gun, and a
terminal to Release the Safety Lockdown: do that.
Mission 8: Fight: Main Lobby
Exiting the security area, there's a handful of The Possessed to dispatch.
Then a Possessed Soldier or two, and finally a Possessed Security and a
Hell Knight in the main lobby area. Keep moving and focus on the meaner
demons.
Watch a holographic replay of Dr Hayden and Olivia Pierce arguing about
her research. Meanwhile, pick up CODEX ENTRY "Environments / Advanced
Research Complex 2" from the main desk. When you interact with the panel
to open the main building, there will be a Checkpoint, so gather supplies
before that - the upcoming fight can be a bit difficult.
Mission 8: Fight: Central Area of ARC
The entryway contains 6 Imps worshipping or something. Use a grenade or
whatever you need for weapon or rune upgrades.
Drop down to the lower central area, where you'll find 6-8? The Possesseds
worshipping a Gore Nest. Often, an Imp for above will escape and find you
as you are down here: watch out!
My strategy for the start of this fight: Destroy the Gore Nest; lob a
grenade into the center where Imps are forming in front of you (this tends
to be quite effective), do a U-Turn to find 2 Imps to blow away with Super
Shotgun. A Mancubus has formed in the tunnel to your left: kill it with
whatever means, including Chainsaw (there's more fuel in the central area
near the Gore Nest's location).
Once the Summoner comes into existence, grab the Berserk Powerup. In a mad
rage you'll likely be able to kill nearly all the remaining demons, but
focus on the hard to kill demons just in case, as possible.
Mission 8: Meeting Dr Hayden
All the bad guys being dispatched, follow the in-game waypoint to Dr
Samuel Hayden's office.
POINT OF NO RETURN: You can't come back here, so if you are missing the
Auto-Map or the Elite Guard, get them now. (??? check that they're even
still available post-fight?)
Dr Hayden will resupply you to a large extent (he could really use a Mega
Health but whatever). He will also explain about the "Helix Stone" and Dr
Pierce's private lab "across the chasm". Finally he directs you to the
service elevator: classy.
The Dr is in no mood for futher conversation, so take the service
elevator. When the door opens, find CODEX ENTRY "UAC Personnel / Dr Samuel
Hayden 3".
Mission 8: Moxim Service Bay
The olive green area has 4? The Possesseds. Kill them and find ELITE GUARD
8.2 in this area.
Continue along to get charged by a Possessed Engineer.
Mission 8: Fight: Gore Nest 1
This fight takes place in a small-ish pit area. There's a Haste Powerup.
The pre-fight is all Possessed Engineers and is unlikely to be a problem.
Often they materialize rather late anyways. ???
The initially a Cyber-Mancubus appears in front of you; then 2 Mancubi;
then another Cyber-Mancubus; along with 6? Imps.
Mission 8: The Chasm: Secrets Galore
Go to the marker indicated by the game, and interact with the screen to
"Lower Security Field".
First, there's the RUNE CHALLENGE 8.1 (SECRET 8.8). Look out onto the big
chasm and turn 90 degrees left to find an airlock. Use it to access Rune
Trial "Blood Fueled" (I personally don't use this one). There also a suit
of armor.
Second, there's the Classic Doom Level, SECRET 8.10. This jump to the
lever is pretty tricky.
Jump across to the immediate platform, and turn left and drop onto the
platform below the Gas can. Turn around and look to the left to see a
green light-bar, indicating a platform you can jump to. Keep going around
this rock and jumping up: the top has a suit of armor on it. From this
top, look directly opposite from the entrance area. You should see some
pipes and a lever at your exact elevation: you need to jump there. The
trick is that there is an invisible ledge about 12' (4 meters) below the
level. If you land on that it is confusing: but if you have the In-Flight
Mobility Rune you should easily be able to jump from this awkward position
to the Lever. The upgraded In-Flight Mobility Rune helps too (make sure to
activate it).
(It is also possible to access this switch from the platform near the
megahealth described below. It's perhaps a bit easier.)
Third, from the Lever, face the piping and jump onto the pipe. Duck and
turn into the cave, and search around into you find SECRET 8.6,
COLLECTIBLE 8.1, "Supershotgun Model / Phobosguy"
From there, look out for Lost Souls, and jump around until you get where
they suit of armor was (on top of the rock). From there, jump back toward
the entrance, and keep going that direction to find the Classic Doom Level
(SECRET 8.10)
Fourth, go, yet again, to the high point where the suit of armor was. Look
for a lower pinnacle and jump there. From there, it is about a 45-degree
right-turn to the Mega Health Powerup, SECRET 8.5. Once you get this
powerup, a Cacodaemon will rise to attack you.
Fifth, from where the Cacodaemon appeared, look for a bay opening. It
contains an ARGENT CELL 8.1, SECRET 8.4.
Finally, look for a hatch that is opening and closing (the in-game
waypoint should lead you here). Jump down onto it for an irreversible
Checkpoint.
Mission 8: Twin Intake Area
Here we are in a pair of air intakes. If you look around you should see a
Field Drone behind a grate: it is actually in the space directly in
between the twin intakes. But it must be accessed from the other side.
Jump onto one of the rectangular panels, and jump onto the only walkway.
You should see a green-lit hatch to jump to. We want to get to the top of
the air intake: we could do it here, but we should access the Field Drone
first.
So, walk through the tunnel: an Imp will jump out.
Keep going: you'll get to the other intake. Turn it off using the panel,
and jump down the hatch (just like the one you came up). You should find a
shaft with FIELD DRONE 8.1 in it.
Reverse your steps, and turn the air intake back on. Step in, and enjoy
the ride up!
Climbing up you'll get to a 4-way shaft intersection: directly in front
and in back of you are each of the twin intakes. The in-game waypoint
points you toward BFG Labs Lobby. The other direction has some armor if
you need it.
Proceed toward the in-game waypoint, to a lobby. This area has TWO green
door: the big one directly in front of you with the waypoint, and a
smaller door to the left housing SECRET 8.3: ELITE GUARD 8.3.
Mission 8: Fight: The BFG Labs Access Hallway
Now, go forward into the ring of labs in the BFG complex. Get a big gun
out and shoot 5 Possessed Soldiers, 2 Possessed Securities, and 1
Cyber-Mancubus.
I usually use a super-shotgun to start, then a mix of rockets and gauss
cannon to finish the Cyber-Mancubus.
Mission 8: Notes on the BFG Labs
Let's look at the labs on the outside of the hallway-ring.
I'm going to go clockwise (as seen from above) starting at the Yellow
Door.
* Yellow Door: find a Torso whose retina will grant you access to the
BFG itself
* Bluish Door "Prototype Lab 02". 4 The Possesseds.
* Red-lit Door-ish area: there's a corpse, a Gauss Cannon and some
plasma fuel.
* Bluish Door "Prototype Lab 01". 4 The Possesseds. Once these guys are
dead, stand on the machinery and look for an open duct. SECRET 8.2,
COLLECTIBLE 8.2: "Pinky Model: Pinkguy" ??? Follow the duct to drop
into a room with a The Possessed, plus CODEX ENTRY "Weapons /
BFG-9000". Go out this door into the main circular hall
That's it: now go to the in-game waypoint and interact with it.
You can probably figure out how to get the BFG from here, but the next
section will spare no details.
Mission 8: Accessing the BFG (Defeating the Security Measure)
Enter the chamber; the alarm will sound, i guess it noticed that the
retina was attached to a corpse. Anyways, jump onto any of the symmetric
metal platforms (on the walls), and watch the crazy security apparatus.
After about 10 seconds, a sequence of lamps will light up and you can to
shoot the obvious cells (you need to shoot 4 of the 6 cells). Do so, and
the security system collapses and you can claim the BFG for your arsenal.
Watch the cut-scene.
Mission 8: Fight: Test The BFG
This fight is designed to be a nice place to use the BFG, for casual
players. But it's probably better to work on all kinds of Weapon Upgrades
(Super Shotgun, Gauss Cannon-Siege Mode, Chain Gun-Mobile Turret).
Mission 8: Before heading out: Rune Challenge "Intimacy is Best"
Watch the holographic replay.
Before going ahead, go right through a newly green-lit door; turn left
into a yellow-gold-lit narrow opening to SECRET 8.9, RUNE CHALLENGE 8.2
"Intimacy is Best"
Mission 8: Gore Nest 2
Now, charge forward into a battle designed to showcase the BFG (and you
may as well use it, since you can only store 3 charges.)
Prefight: use a few Siege Mode/Gauss Cannons to kill the incoming hordes
from the Checkpoint. After that, coming into this area, 3 Lost Souls will
spawn: one straight in front, one left, one right. After you learn where
they spawn they are easy to deal with - and since you have to re-kill them
every time you die in this battle, you'll probably learn where they spawn
too.
Now, destroy the Gore Nest. Use the most powerful weapons available.
When you think you are done, it's a bit of a trap. You have NOT gotten to
a Checkpoint until you kill the 2 Hell Barons that follow.
A robotic voice will announce that the demonic threat level is reduced,
but that is just a temporary reprieve: not a Checkpoint.
However, one easy BFG blast will take care of both Hell Barons.
To conclude the level, enter the elevator and "Exit Facility".
Mission 9: Lazarus Labs "Lazarus"
Notes on Combat Challenges:
* Variety is the Spice of Death II: note that glory kills on Hell Razers
count as well.
* Thread the Needle: use the BFG. There's two fights shortly after
acquiring it that should reliably achieve this.
* Time Well Spent: easy, but also easy to miss. Make sure you do it
before leaving Olivia's back lab.
Mission 9: Intro
Grab Gas, the CODEX ENTRY "Environments / Lazarus Labs", and recharge your
health (you can't get back here). In the next room you can get the rarely
used Siphon Grenade. Then jump down the chute.
There's a number of The Possesseds, Possessed Soldier and Hell Razers
(glory kill them different ways to work on the Combat Challenge), and a
Pinkie.
Following the waypoint, you'll remove a corpse-chunk that's blocking the
elevator, and 3 Imps will jump out. Kill them, then use the Munitions
Crate. The non-Secret flow is to jump into the shaft and open a grate.
Instead, look behind the crates behind the Munitions Crate. There's a duct
(SECRET 9.1): follow it to a Mega Health that'll drop you into the next
fight.
Mission 9: Fight: First Warehouse
A big fight, with many Hell Knights and Revenants.
Kill all these guys, and enter the green-lit doorway.
Mission 9: More Secrets
Go up some stairs in a red-lit area. Before continuing on, turn around to
see a duct with shotgun ammo. Jump into the duct, and follow it to a
grate, that you may open. Enter SECRET 9.5. Here is ELITE GUARD 9.1 and
CODEX ENTRY "Database / Elite Guard 2".
Now, continue toward the in-game waypoint. You'll pass through a
transparent walkway while Dr Hayden tries to explain things. There's lots
of activity outside.
At the end of this walkway, find FIELD DRONE 9.1 (although you may have
already gotten the good upgrades).
You'll find yourself in a curving hallway with 4 The Possesseds, and CODEX
ENTRY "Monsters / Cyberdaemon 2".
Continue down the hall to a few Possessed Soldiers and a Hell Knight.
Continue up a short flight of stairs and look for a white hatch in the
floor right in front of you. Interact with it to drop with for SECRET 9.2.
Climb up to find RUNE CHALLENGE 9.1 "Rich Get Richer".
When done, actuate the screen near the door to exit - you'll be back at
the hatch.
From the hatch, go into the next room: there should be two large steamy
windows in this relatively small area. Facing the windows (as you come
into the room), look right for a torn duct you can climb into. Drop down
into an area with the AUTO-MAP. Exit through a duct behind the columnar
structure in the room. You'll come to an old school looking panel of
lights. Jump up, and look for a grating to open, to exit back to an early
hall.
Mission 9: Fight: Miscellaneous Hallway Guards
The first room has a few Possessed Securities and many The Possesseds and
a couple of Possessed Engineers.
The second room has a CHECKPOINT (used for the next fight) and 4 Possessed
Soldiers and a Hell-Razer. The next room has a bunch of ammo and a Health
Station, then drop down the hatch to enter the next fight.
POINT OF NO RETURN: Once you finish the next fight, you cannot get back to
this tunnel area (so make sure you interact with Rich Get Richer, even if
you don't solve it)
Mission 9: Fight: Mancubus Operating Room
Many Possessed Securities, The Possessed, Hell Razers, Possessed Solders,
3 Mancubi will spawn. Toward the end of the fight is 2 Hell Knights. I
like using the Plasma Rifle Heat Wave with the Quad Damage to plow through
the bad guys - but your mileage may vary.
After the fight look at the empty mancubus bed at the back of the room,
between the two exit doors. Behind this, is a screen you can actuate to
find ELITE GUARD 9.2 in SECRET 9.4.
Mission 9: Fight: Stone Tablet Exhibit Hall
There's a Munitions Crate in the entrance hallway to this area. Once
you've looted the area, look through the door to see if you're going to be
ambushed by a Possessed Soldier right next to the entrance. Open the door.
This fight begins with 3? Possessed Soldiers (one is close-by and needs to
be dealt with urgently) and a large number of The Possesseds (use a
grenade or two maybe). (Here's your first good change to get the Thread
the Needle combat challenge). Shortly, 2 Pinkies spawn at the back of the
room.
Killing those Pinkies will cause the spawning of 4 more Pinkies and a bevy
of Imps. Use the BFG, Chainsaw, and general evasive maneuvering.
Cheap Strategy: After killing the Possessed Soldiers, go into the tunnels
behind the stone artifacts. The monsters (most conveniently, the Pinkies)
cannot go back there, but Imps can still fireball you. You may need to
chainsaw someone for ammo: the second Pinkie can be a good choice.
Post-Fight: Going back to the entrance door of the room, and look at the
stone tablet to your left. There is a gap you can use to enter some access
tunnels: this is SECRET 9.3. In the back, find COLLECTIBLE 9.1 "Olivia
Pierce Model, Eliteguy".
There's also a Mega-Health you should take before leaving the backstage
area. (Hint: equip Rich Get Richer before taking the health to get one of
the Upgrades)
Cheap Strategy for upgrading the Rich get Richer Rune here: If you don't
use the Mega-Health during the fight, then you can obtain it repetitively
after checkpointing. But you'll have to die in order to reset the
checkpoint. (the cheap strategy is not appealing anymore since a non-dying
strategy is available in Titan's Realm.)
Press the screen as indicated by the in-game waypoint. Enter what looks
like an elevator to transfer you to the Lazarus Archives.
Mission 9: Accessing the Helix Stone
This really just involves interacting with a few screens, in all cases,
the in-game waypoint takes you there.
SECRET 9.6, COLLECTIBLE 9.2 "Samuel Hayden Model, Toxicguy" is found in
the circular archive room. Look on the upper floor for a red display
screen (there's another similar display in a cyan color: ignore it).
Behind it, a single archive cell's light is red -- all the other lights
are yellow. Interact with this to obtain the doll.
The anteroom to Olivia's Lab holds CODEX ENTRY "UAC Personnel / Olivia
Pierce".
After a few screens, you be in Olivia's Private Lab: there's a central
hologram of a stone coffin-like thing being guarded. There's BFG Ammo, a
Munitions Crate, an ARGENT CELL 9.1, and a screen to interact with. On the
left is a lone dilapidated computer where Demon Destruction can be
"played": just interact with the running computer on the side and exit to
get the Combat Challenge.
The final screen is back in the circular archive room: be ready for a
fight after Dr Hayden rambles on a while.
Mission 9: Fight: Circular Archive Room
Be prepared for a endless Imps and a long sequence of Hell Knights. An
Mancubus will spawn; and toward the end, 2? Cacodaemons.
After dispensing with all the demons, a circular stairway drops down from
the center of the room.
Mission 9: Fight: Small fight in Bloody Temple / Pew Area
A few Possessed Securities and a bunch of The Possesseds linger about this
gory area.
When cleared, there will be a hologram of Olivia watching over a
ritualistic sacrifice.
There's armor behind you as you stand in the entranceway to this area.
Mission 9: Circular Hatch Room
Exit to the right to a blood-strewn corridor with books and candles.
You will get to a circular room with a pit in the center. Looking in, you
can see an Elite Guard, but before that, look right for a Lever to access
a Classic Map.
Now, jump in (SECRET 9.7) and get ELITE GUARD 9.3 and SECRET 9.8, CLASSIC
MAP 8.1 "Doom - Tower of Babel".
Jump back out, and go to the screen with the waypoint: "Cycle Hatch".
Do this, and jump onto the platform while it is plugging the hole. Wait
for it to lift you up, like an elevator.
Drop down, and keep going and you'll get to a yellow-lit door labeled
"Maintenance Only". Enter for a fight.
Mission 9: Fight: Server Hall
You catch a few Possessed Securities off-guard, use grenades etc. There's
also a Pinkie ahead of you in the hallway. And a few more The Possesseds -
including some that may surprise you by popping up.
Mission 9: Server Hall
The hallway become increasingly bloody, and you finally open a door onto a
console area. A hologram with Olivia is playing, and you must interact
with a terminal at the waypoint here, the energy refractor control. It
opens the twin doors.
Mission 9: Fight: Two-Level Lounges
Two identical hallways (with bloody skeleton wallpaper), take you to a
symmetric 2-level area strewn with Imps, Possessed Soldiers but mostly The
Possessed.
Once cleared, from the entry, go to the lounge on the right on the
upper-floor. Look around for a bloody duct at approximately head-height.
It takes you to SECRET 9.9, RUNE CHALLENGE 9.2, "Saving Throw".
There's also ELITE GUARD 9.4. Outside the door, in the non-secret area, is
a Munitions Crate.
Then go to the waypoint: a large silo with green concentric circles
surrounding the waypoint itself.
Mission 9: Portal Area Fight
The robotic voice announces demonic presence, but you won't see much. You
have to enter the narrow hallway and go through the teleporter.
Before doing so, equip In-Flight Mobility. Then enter the teleporter and
jump back. You should land on a shelf instead of falling to the ground.
This is the perfect place to use the BFG to get the Thread The Needle
Combat Challenge: it'll make the fight much easier too.
This is a good fight to use the Plasma Gun / Heat Blast - fight everyone -
grabbing the Haste Powerup whenever you need health. Use another BFG if
helpful - there's a few lying around. When the Pinkie or Hell Knights show
up, grab the Quad Powerup: it (along with Heat Blast) should be easy work
of the remaining heaps of demons.
Mission 9: Prepare for Boss fight
Follow waypoints, grabbing supplies, along with CODEX ENTRY "Monsters /
Cyberdemon".
Dr Hayden explains that this fight will have two parts. The first part is
the easier one.
You will get 6 bonus Weapon Upgrade Points before the fight begins.
Mission 9: Boss Fight, part 1: Mars
Here's the most notable Cyberdemon moves for the first part:
* the Rockets: he'll launch a volley of horizontal rockets; so long as
you keep moving you should be ok.
* the Charge: things will slow as he prepares to charge, so get ready to
jump away.
* the Jumpable Laser Shot: this thing does a lot of damage so you really
need to jump over it.
* the Charged Laser: this multiple beam laser shoot from his arm. It
starts red and intensifies to whitish-yellow before firing. You really
benefit from the In-Flight Mobility Rune for dodging this - upgraded
is better.
* the Mortar Volley: he will launch a bunch of rockets upward; their
projected landing spots will be on the ground - find a place in
between them to stand. This attack is combined with a Charge, a
Jumpable Laser Shot, or a Changed Laser.
* the Sidejump: he will sometimes take a big jump to the side. This is
his (pretty effective) move against slow Gauss Cannon and BFG
enthusiasts: don't waste your ammo if you detect it.
Recommended Runes: Vacuum, Ammo Boost, In-Flight Mobility. (notes: Armored
Offensive is useless since he doesn't drop armor. Saving Throw is
marginal. Rich Get Richer is good if you have 100 armor (unlikely). He
stays staggered for a while, so Dazed and Confused isn't really helpful.)
Mission 9: Boss Fight, part 2: Hell
A small cut-scene transports you to Hell; the Cyberdemon gives you the
claw, and is reborn. You will also be pretty well charged up.
He adds two new attacks to his repetoire:
* the Triple Jumpable Laser Shot. The first shot will be low; the second
high; and the third low. It just takes practice. Easy mistake:
double-jumping the first laser and getting hit by the second.
* the Double Wall. He makes a temporary corridor, which'll be combined
with a Triple Jumpable Laser Shot or Rockets. To deal with the Double
Wall with Rockets, move in a circular pattern using In-Flight
Mobility.
Same Rune Notes apply as above.
Feel free to use all of your BFG ammo.
You will get 2 Weapon Upgrade tokens.
When the fight is over, jump into the red teleporter.
Mission 10: Titan's Realm "Titan's Realm"
Notes on Combat Challenges:
* Trick Shot: I don't know why, but using the Rocket Launcher's Lock On
mode seems to achieve this reliably. There are other ways, but I
haven't found anything as consistent.
* Atop the Mountain: there's a number of fights that end with the Hell
Baron. For some reason, i often accidentally kill them instead of
staggering them. You have to jump from higher ground to do this! This
fight where you get the Blue Skull is probably the easiest to get this
on, because the Hell Baron starts in a pit.
* Dominator: there's a Berserk Powerup that is your main helper here.
Mission 10: Introduction
From the walkway, find CODEX ENTRY "Artifacts / Slayer's Testament #4".
Mission 10: First Fight
Jump far down to a bloody pit to be immediately attacked by 3 Cacodaemons.
As proceed up the stairs to be attacked by another Cacodaemon and a
Cyber-Mancubus.
Continue up the hellish path to a yellowish cave guarded by 4 Lost Souls
and 2 Cacodaemons.
CHECKPOINT.
Enter this room: you should see a bridge over a pool of toxic sludge. If
you look under the bridge, you can see a Skull Switch. Actuate it and get
out of the sludge. Facing into the room from the entrance, this caused an
alcove to open up on the toxic floor, right next to a green torch. Inside
this alcove is SECRET 10.3. ELITE GUARD 10.1. And some armor.
Mission 10: Fight: Entrance Hallway
Proceed, triggering the creation of some Lost Souls, some Hell Razers and
a Pinkie.
Proceed to the right. When you grab the suit of armor, it'll trigger 2
Hell Knights to instantly appear. There are also 4 Unwilling in the next
room, along with a Skull Switch: press it.
This'll trigger the spawning of a Cyber-Mancubus, which will end this
fight.
CHECKPOINT.
Now, pick up loot and search around for the FIELD DRONE 10.1, SECRET 10.2
(it was visible before so it may be on the map).
Proceed to the next fight: the target will be a gated-off green
teleporter, but some demons will distract you en-route.
Mission 10: Fight: First Teleporter
Upon entry to this complicated arena, a Cyber-Mancubus will spawn off to
your left, and a Mancubus will spawn in the area in front of you. Polish
them off however is convenient.
A gaggle of other daemons come along as well. A few Imps, few Revenants, 2
Pinkies.
Use the Haste since this is the only fight in this area - use it to work
on the Dominator Combat Challenge.
Once you get the CHECKPOINT, approach the Teleporter and the bars will
lift. Enter for an iconic fight.
Mission 10: Fight: Bloody Cave
Dave's Opening: I usually turn right coming out of the Teleporter, picking
up shotgun ammo and a suit of armor. Look left into a cave before a Yellow
Lift: there should be Rockets on the ground and a Quad Powerup in the
background. In a few seconds, a Mancubus will appear right on the rockets:
lob some grenades and go up the stairs right past the Yellow Lift. You
should find a Gas can, and down the hallway, the only Pinkie in this
fight. Kill it and then run and fight as usual.
The finale is 2 Hell Barons. I often save the Quad Powerup for them (note
that 4 Imps spawn when you take the Powerup).
Post Fight: the map may have a doll on it: SECRET 10.1, COLLECTIBLE 10.1
"BFG-9000 Model / Keenguy". If not, it's in an alcove of the entrance
wall.
Follow the in-game waypoint to the teleporter. You'll arrive at the
Auto-Map, use it.
Mission 10: Fight: Rectangular Pit
After 6 Lost Souls, deal with 4? Hell Razers and a bunch of Imps. They can
be mostly killed just by shooting barrels. Use the Rocket Launcher on the
Lost Souls to get the Trick Shot award or kill them however you want.
Mission 10: The Yellow Skull and its Door
Post fight: look for a Yellow Lift near the red door to get you onto the
rafters. Across the way is a yellow pyre: jump to it for SECRET 10.4,
COLLECTIBLE 10.2: "Cyberdemon Model, Silverguy". Jump back.
Now jump over to the landing with the green suit of armor and a
wood-grid-patterned door. It'll open and you can take the Yellow Skull.
But! It's a trap. A very easy obvious trap. I think you'll figure it out.
Continue through the hall (in the direction of the greenish area with the
gibbet - the area you haven't been to yet).
A grate will appear to block access to the yellow door.
So, you must go left into a toxic area with a bunch of Unwilling
staggering around. You will see an Invulnerability Powerup here, and at
the end of the corridor, an ELITE GUARD 10.2 and a Skull Switch. Activate
the Skull Switch.
Mission 10: Fight: Toxic Sludge Area
On return, two hatches will open exposing 2 Mancubi. You can use the
Invulnerability on them, or fight more carefully and save it for a minute.
Once they are gone, take the Invulnerability if you haven't and run up the
stairs to fight 3 Pinkies.
After that, the Yellow Skull Door is accessible, and a CHECKPOINT.
Before going through the Yellow Door, though, note that another passage
has opened and get ARGENT CELL 10.1 and CODEX ENTRY "Monster / Pinky".
(Actually, if you want to get the Rich is Richer upgrade, I recommend
waiting for after the following fight)
Mission 10: Fight: Pounding Rock Area
The Yellow Skull Door opens to reveal what appears to be a red skull
switch, but it's a trap: the floor drops out and suddenly you are fighting
a Mancubus, then 2 Revenants and a Hell Knight with some Imps in the
background.
At some point, 2 more Mancubi and a Cyber-Mancubus spawn as well.
Note that there's BFG ammo here, so if you are full, feel free to use it!
NOTE: the nearby acid pools allow you to reliably inflict just 1 point of
damage, which makes this area very convenient to get the Rich Get Richer
Rune upgrade. In order to do that, do NOT pick up all the armor during the
fight, you want about 4-8 stray armor left, at least.
Mission 10: Pounding Rock Area
When the pounding rock is down, quickly climb onto it. It'll lift you up
to a Skull Switch: press it, and drop down.
Before continuing, to toward the Yellow Door, which is currently gated
off. Look for a small alcove continuing the Classic Doom Map Lever. Pull
it. The gate to the Yellow Skull Door will open: go that way and go back
to the lower Toxic Sludge room (where the Mancubi appeared with the Elite
Guard), and you'll find CLASSIC MAP 10.1 "Phobos Anomaly": SECRET 10.5.
This area also has a Mega-Health: Go down a corridor and interact with a
discolored wall-panel on the right-side to get the Mega-Health.
Go back to the Pounding Rock Area. Go toward a gated off green teleporter.
Look left to see a large room with 2 Yellow Lifts and a Suit of Armor in
the middle.
Go in to what I call the Treasure Room, and pick up some loot and a Blue
Skull, a fight is triggered on the way out.
Mission 10: Fight: Treasure Room
It starts right near the entrance/exit with 3 SPECTRES. This is quickly
followed by some Imps and 4 Lost Souls. Then 2 Cacodaemons and 3 Mancubi.
Finally, a Hell Baron.
CHECKPOINT.
Mission 10: Segue
Now, after checking for stray supplies, enter the green teleporter (the
bars will disappear as you approach).
You'll be in a fiery yellow lit area.
Grab CODEX ENTRY "Artifacts / Slayer's Testament V". Turn left for SECRET
10.6: a Mega Health (don't forget Rich Get Richer upgrade).
Continuing along, you'll be back at the Rectangular Pit.
Mission 10: Fight: Rectangular Pit, Blue Skull Door Fight
A Berserk Powerup has been placed for this fight. It starts with many Imps
and also include a 3 Hell Knights, 2 Summoners, a Mancubus. It ends with a
Hell Baron.
Use the Blue Skull, and find immediately on the floor CODEX ENTRY "UAC
Personnel / Olivia Pierce".
Jump into the red teleporter.
Mission 11: The Necropolis
You find yourself in a central area of this level with the Yellow and Blue
Skull doors adjacent.
Notes on Combat Challenges:
* A Pin Pops a Balloon: there are two clear opportunities for this.
Right at the beginning, and after crossing the floating islands with
Cacodemons. Try both, since it can be pretty easy to kill the Mancubus
accidentally. Dazed and Confused Rune can help a little as can ???.
* Two Mouths to Feed: when you cross on the floating islands there's an
easy place to get this. Use Gauss Cannon / Siege Mode or BFG.
* Wait For It: By kicking the first barrel down the steps you can get 3
there; and the pre-fight in the Square room has 6 Possessed that are
easy to get. There's a number of other chances if you don't die on
those scenes (the kills count even if you die!)
Mission 11: Yellow Skull
To your left at ground level is a teleporter. Jump into it.
Find CODEX ENTRY, "Monsters / Cyber-Mancubus".
Mission 11: Fight: Yellow Skull Prefight
Continue along to a barrel at the top of the stairs, if you kick it down
you can shoot it to kill some demons, for the Challenge.
Descend the stairs and quickly look back to shoot 2 Lost Souls. A Mancubus
appears at the top of the stairs: he's a good one to use for the Pin Pops
a Balloon Challenge. If you climb the stairs, 2 more Lost Souls appear.
Mission 11: Treats
A CODEX ENTRY "Artifacts / Slayer's Testament #6", Gas, and ARGENT CELL
11.1 (the last) are found by continuing down the corridor.
Mission 11: Fight: Traps
Go back up the stairs to where a gate has opened: you should see a Skull
Switch straight ahead in the next room, but as you approach it, a bunch of
Unwilling and a Spectre spawn.
Kill them and actuate the switch, causing 2 Hell Knights to spawn as you
return. Go back down the stairs and kill a Cyber-Mancubus.
CHECKPOINT.
Mission 11: Fight: Square Arena
This is a square torchlit bloody room with 4 big pillars.
Prefight: there a bunch of Unwilling roaming about and barrels: use them
to work on the Wait for It Challenge. It's your best opportunity.
After pressing the switch, the fight proper begins.
3 Cacodaemons spawn, 2 Hell Razers and some Imps and 2 Spectres in quick
succession. Then 2? Hell Knights and a Summoner.
Grab the Auto-Map, pull the Classic Map Doom Lever, and grab the Yellow
Skull.
CLASSIC MAP 11.1 "Doom - House of Pain" is SECRET 11.3. Go back outside
this room and down a hall to an area that looks funky on the map.
This will trigger the teleporter to open, and you can take it to return to
the central room you started in.
On the opposite side, a new Teleporter has opened. This one will get you
the Blue Skull.
Go through the teleport for the next fight.
Mission 11: Fight: Four Platform Arena
Soon upon entering, 2 Mancubi form on 2 of the platforms (two Gauss Cannon
Siege Mode blasts will take both of them). Then 3 Cacodaemons and Imps.
Then some Revenants and a Hell Knight ends this wave.
The gates surrounding the Quad Powerup lift and 4 Revenants spawn, one on
each side of the square. Then 2 Cyber-Mancubi and 2 Mancubi spawn: the end
of the fight.
Take the Blue Skull. Teleport back to the Central Room.
Mission 11: Fight: Central Room
Use both Skulls, an interact with the knobs behind each door to trigger
the next battle.
3 Imps spawn in reliable location.
2 Pinkies are next.
2 Revenants, a Hell Knight and ? Spectre make up the next wave.
The final wave is 2 Hell Barons.
After the fight, two stair cases open up below the main area (see map), go
there and drop into a small hallway with some health and another drop.
Mission 11: Fight: Cacodaemons in Air
When you stand up from the jump, there will be 3 Cacodaemons lurking
around.
Use BFG or (better) Gauss Cannon Siege Mode to get the "Two Mouths to
Feed" Challenge.
Jump onto the next platform, which has two large unlit torch/pillars on
it.
The next platform has just one torch/pillar. Peer carefully down from the
edge to see a small island. Sometimes you can catch sight of it from
above, but often you cannot, but there is a doll on it. In-Flight Mobility
helps (but is not necessary) to jump down there. This is SECRET 11.2,
COLLECTIBLE 11.1 "Chainsaw Model, Tealguy".
Continue hopping to the cave, where you will be greated by a Mancubus.
Don't forget to get ELITE GUARD 11.1, and there's some armor too.
Continue along to some shotgun ammo and the last FIELD DRONE 11.1.
Mission 11: Fight: Big Battle In-Progress
Go up the stairs so where some big demons are duking it out: 2 Mancubi,
some Revenants, Imps, and a Cacodaemon. Help them kill eachother and kill
the Hell Razers, 2 Cyber-Mancubi and whatever else spawns. There's a BFG
and a Haste Powerup.
You'll want to get in good shape for the next fight.
Mission 11: Fight: Paired Hallway
The same demons will spawn on each end of this hall. I'll give total
numbers:
* 2 Hell Barons
* 2 Mancubi
* 4 Spectres
There's quite a bit of ammo around, and ELITE GUARD 11.2.
Mission 11: Fight: Last Non-Boss Fight
Exiting, 2 Cacodaemons will immediately stalk you: kill them with the
rocket launcher: there's ammo around.
Walk down to the treasure trove with a big armor. This will trigger 2
Mancubi to spawn. Retreat back to the original area and use Rockets, Gauss
Cannon. Once you kill a Mancubi, 2 Hell Barons will spawn. Gauss Cannon or
BFG is recommended: it won't take long for them to get to you.
Now, you can get an obscure secret, SECRET 11.1. Look at the large statue
/ structure that is shaped like the head of a horned screaming demon. In
its forehead, is a glowing pink rune symbol. Shoot it (with Gauss Cannon
or Rocket Launcher or Assault Rifle/Tactical Scope, since you need range),
and a weird cubic capsule will spit out of it and land next to you. This
is COLLECTIBLE 11.2 "Gauss Cannon Model, Hazmatguy".
Stock up, there are two Boss Fights coming up.
Mission 11: Boss Fight 1: Hell Guard
This fellow has a force field (the transparent green sphere) that'll
protect him from everything, even BFGs, so you must time your shots for
when the field is down. Most of his attacks give you an opening.
His moves:
* Club Attack. He comes at you, move and aim, since his field is down as
he attacks, and right afterward.
* Charged Club Attack. Similar, but he puts more into it and damages
everything is a radius (which briefly flames up).
* Tri-Sphere Attack. He blows up a glowing yellow sphere, which briefly
flashes, then turns almost white, then 3 very damaging shots are
launched out. This can only be attacked after blinking but before
shooting. The good news is that it stuns him for a bigger (Siege or
BFG) secondary attack.
Midway through the fight he gains some new tricks:
* Spinning Flaming Spiral. Avoid the flames: after this he'll be
attackable for an unusually long window.
* Three Drum Waves. He beats the ground creating a relatively slow
moving wave that does a lot of damage.
Toward the end, you may wish to equip Dazed and Confused, since he doesn't
stay staggered long, and you have to Glory Kill him.
Mission 11: Boss Fight 2: The Twin Hell Guards
These guys really act in concert, but it's easier to describe their moves
separately. They lack the force-field, fortunately.
* Bed of Fire. One runs creating a sequence of long fireballs. Just jump
over them.
* Fire Tornado. One spins creating a whirlwind of fire. Avoid.
* Sphere Attack. Like above but it doesn't flash or trifurcate. Shoot it
right after it finishes inflating to stun him.
When one is stunned, you can often line them up to get double damage out
of Siege Mode or BFG.
When they are getting low (20%), switch on Dazed and Confused so that you
will have an easier time Glory Killing them.
You will get 2 Weapon Upgrade points for killing these guys.
After killing them, access the Crucible (which looks more like a dagger
with a Skull at the top).
Mission 12: VEGA Central Processing
Notes on Combat Challenges:
* Variety is the Spice of Death III: there's a lot of Imps, including 4
right soon after entering the building. Possessed Engineers also can
be glory-killed to satisfy this requirement.
* Gore Pinata: Plenty of opportunities for this as well. (The Equipment
Rune and its upgrade help quite a bit)
* My Teeth are Sharper: you can jump and chainsaw if needed.
Mission 12: Intro
Enter either door, and in the Console area look for CODEX ENTRY "UAC
Personnel / VEGA".
</pre><pre id="faqspan-4">
Proceed to open the airlock, and get Gas or Ammo if you want it. Stop
about 115 meters shy of the waypoint. Look for a green-lit Mainenance
Hatch. Enter it instead of going to the waypoint.
In one shaft here find COLLECTIBLE 12.1 "Hell Guard Model / Quakeguy"
(SECRET 12.1) and a BFG ammo in the next shaft. Drop into the main area
from the first shaft, possibly conservatively since there's about 5 Imps
in there.
Another Maintenance Door at ground level is followed by a green-lit hatch
in the floor.
Drop down to the area with the Security Switches.
Mission 12: First Switch Fight
Many Imps, Possessed Soldiers, and Revenants spawn when you activate the
first switch (the second switch doesn't trigger any spawning).
This multistory area has many pickups, and the area is reused for the next
fight.
Mission 12: Security Shutdown Fight
Flipping the second switch does not cause any new demons to spawn.
But, disabling security does cause 2 Cacodaemons and a Cyber-Mancubus to
spawn. This fight can be won in a single BFG shot if you venture forward
about 5 seconds after disabling the security system.
Mission 12: Cooling Access Fight
Note: you can use the Berserk from the earlier fight.
A few Possessed Securities and 3 Pinkies and a Mancubus scattered across
about 4 rooms. A Health Station and CODEX ENTRY "Monsters / Revenant" are
found near eachother. There also two Elevator Shafts off to the side that
have 2 Possessed Soldiers and a BFG ammo.
Mission 12: Finding the Blue Keycard
Back near the Health Station look for a very bloody side area with
entrails hanging from the ceiling and a chainsaw. Enter and look for a
hatch.
Drop down to find a bunch of Possessed Engineers, The Possesseds, and 2
Spectres.
But most importantly, the Blue Keycard.
Go through the Blue Door.
Turn Left to find the Auto Map (if you haven't already), and continue in
through another Blue Door.
You'll find a SECRET 12.2, ELITE GUARD 12.2 here, and get surprised by a
Revenant.
Behind the crate that the Guard is leaning on is a Lever: pull it to open
access to the classic doom level. Then go back past the Blue Keycard guy
and look for a nested pair of crude circles on the map. That is SECRET
12.5, CLASSIC MAP 12.1 "Doom - Command Control".
Look down the shaft the Revenant popped out of. You'll see a Mega Health,
drop down, making sure to get it.
You should be standing on a rectangular duct in a very large icy tunnel.
Drop down the other way for SECRET 12.3, COLLECTIBLE 12.2: "Cyber-Mancubus
Model, Jungleguy". Walk along the duct to get back up. Enter the door to a
tunnel.
It'll drop you into a lobby where a holographic guy is blathering about
how much energy they use.
Continue on.
Mission 12: Fight: Coolant Generator Room
Four Switches must be destroy (by shooting) to reroute the energy. It
doesn't seem to matter much what order you go in.
* Switch 1: 2 Cacodaemons and a Summoner spawn, and a long parade of
Possessed Soldiers and Hell Razers and a few Imps.
* Switch 2: A Hell Baron, 2 Pinkies, another Summoner, 4 Lost Souls.
* Switch 3: Imps, Possessed Soldiers, Hell Razers
* Switch 4: Nothing new spawns :)
After the Demonic Presence is eliminated, and you have taken all the
remaining loot, go to the waypoint and actuate the screen.
Cheesy Strategy: You can hide behind lowest switch: eventually Pinkies
will gang up on you, but then you can take advantage of the Berserk
Powerup in the tunnel leading out of the area. So, the way I usually do
the fight is go left past one switch, then go right and jump up across the
gap to the second switch. Use Tactical Scope to take out the first 2
switches from the same vantage. Then go outside and jump down to the 3rd
switch; sometimes a Cyber-Mancubus will spawn there before you jump:
either chainsaw him or go over/around. Destroy the 3rd switch and hide
behind it, shooting out with the Gauss Cannon / Siege Mode etc. At some
point, grab the Berserk. The cool thing about this is that the monsters
mostly fight each other.
There's also CODEX ENTRY "Monsters / Cyber-Mancubus" in this room.
Follow VEGA's suggestion to jump down onto a train below to enter the last
big battle on Mars.
Mission 12: Fight: Finale
This takes place in a large depot area, with a few BFG Ammo, Gas cans, and
other supplies littered about.
You'll ride the train in and a well-timed BFG can take 2 Cacodaemons and
the 2 Hell Barons plus a whole lot of random demons. Fire it at the 2 Hell
Barons, just as the Cacodaemon at left is about to go out of view.
The next wave consists of a few Cyber-Mancubi, 5? Pinkies, and 3?
Cacodaemons, along with many Imps.
There are 3 BFG ammo here - so you'll probably want to use it a few times.
Mission 12: Destroy VEGA
A waypoint leads to a platform that'll carry you up to ???.
But first, look down below for another platform to jump onto. Jump onto a
ledge which should have SECRET 12.4, ELITE GUARD 12.3 on it (as well as a
Munitions Crate).
Take the elevator back up to the platform.
Wait on it, until you get to a dramatic platform area.
Disable the Neural Networks on the left and right. You will get 5 bonus
Weapon Upgrade points after this is done.
Then go to the center console. Pick up CODEX ENTRY "Environments / VEGA
Central Processing". Then interact with the screen to get a cut scene that
ends the level.
Mission 13: Argent D'Nur
Notes on Combat Challenges:
* Hold Still: only the third fight is good for this, so be careful that
you have both Barons in sight when you use the BFG. It would be
difficult to use the Gauss Cannon to achieve this.
* Uncharted Territory: follow the guide.
* Big [REDACTED] Gun: you'll probably get this without trying; you
probably want to enable Ammo Boost II a lot to get even more BFG ammo.
Mission 13: Introduction
You start in a large upper courtyard area with loot scattered about.
Eventually, go down to a CHECKPOINT for the fight.
Mission 13: Fight: Sniper then Berserk
You should start at an overlook, where you can see a Cacodaemon attacking
a half dozen Imps. I usually kill the Cacodaemon (Assault Rifle with
Tactical Scope) from afar and save the Imps for up close.
Jump down to the courtyard area below and polish off the Imps who will
come to you. The next wave won't start until you enter the main area.
In short order, 2 Hell Knights and a Summoner appear, followed by 2
Pinkies and many Imps.
I usually use one BFG after lots of demons have spawned, then grab the
Berserk Powerup from the very center of the courtyard.
In theory it seems like the "Seek and Destroy" and "Savagery" Runes would
may the beserk powerup more effective - I didn't really notice a
difference though.
When done, exit via the waypoint and CHECKPOINT near the blue teleporter.
Mission 13: Fight: Intro Stairs
Before starting, look ahead to an impressively demonic sight of 3 statues
feeding some central thing. (I'm not sure if the 3 beams symbolize the 3
major fights ahead or not)
Descend to the next level where there is usually between 1 and 3 Unwilling
staggering around (they will fall down to the next level but they can't
get back up, so the exact number varies).
(Because I often seem to need the Mobile Turret upgrade, which involves
killing in groups of 4, i often wait to kill them, but the Secret has to
be triggered before you drop down to the next area)
Facing out toward the canyon, look for a Skull Switch at the right-side of
the level. Actuate it, then go to the other side of this area and look for
some blocks to climb up. After climbing up, there is a cave just a bit
ahead that opened up with Gas and BFG Ammo: SECRET 13.3.
Go back down to the lowest area in this complex with about 8 Unwilling.
Optional: go through the tunnel to the left. Once you take any armor at
the end of the tunnel a Cacodaemon will materialize directly in front of
you, and 2 Imps will appear in the hallway. A few seconds later a Hell
Knight will appear at the far end of the hall (the entrance). (I usually
use Gauss Cannon Siege Mode for the Cacodaemon and the Hell Knight -
separately - and super shotgun for the Imps, but there's many options.
Using a chainsaw on the Hell Knight could make things easy and give you a
lot of ammo)
Optional: go the other way (a right turn, if facing the canyon), to a
rocky set of stairs leading up to the Auto-Map for this level.
Mission 13: Fight: Stragglers on the Islands
Jump across the gorge: keep an eye out over the canyon where 2 Lost Souls
and then a Cacodaemon will spawn.
Jump down and across the canyon.
Go left and turn around to see the next jump.
2 Cacodaemons will appear, one at at time, after you jump across.
This island has two levels: climb to the upper level to see the next jump
target, relatively far below with ??? ammo.
Continue along to an area with a left and right branch: the waypoint leads
left, so instead go right to be surprised by 2 Imps. There's armor here
(etc??)
Go back to the left route, and (I recommend) activate In-Flight Mobility.
Jump around the giant stalactite.
Drop down to hear a demonic voice say "Kill Him".
CHECKPOINT.
Mission 13: Fight: Wraith Fight 1
You can start by sniping the Imps and Hell Knight, if you can see them
from the cliff (you usually can). This can be a good time to get the Gauss
Cannon's Precision Shot upgrade.
Once you go down (irreversibly) into the arena, this fight is dominated by
6 Pinkies and 2+ Hell Knights and a Cacodaemon.
There's a Mega Health right after the CHECKPOINT for this, so it's quite a
good place to start with Rich and Richer with Gauss Cannon / Siege Mode.
There's a Quad-Damage Powerup here as well.
Post Fight: there's a bunch of gear and a near the first Wraith's Soul.
(This pattern will continue for the next two fights)
There's are two parallel stairways leading up there: the one on the left
has a Skull Switch that you should press.
Go to the waypoint by first jumping to the high platform on the far side
of the entrance (it has a BFG ammo on it, initially). From there, jump
into the pale green mouth of a demon statue: it's lit with candles.
Immediately past the mouth, turn right to a passage that only opens after
the Skull Switch is pressed: this is SECRET 13.2. You'll find Gas and BFG
Ammo.
Continue down this secret passage, looking for bloodsmears and a lever on
the left wall. As usual, interact with the level to open SECRET 13.5,
CLASSIC MAP 13.1 "Doom - Pandemonium".
Mission 13: Fight: Wraith Fight 2
Again, snipe a Hell Knight and 2 Imps from above, if you like.
This fight starts with a Pinkie but I think there's only 1. There's tons
of Hell Knights, Revenants, Imps, Hell Razers. And a string of about 4
Cyber-Mancubi that tend to come at the end. The finale is a Cyber-Mancubi
and Hell Baron that spawn at the same time.
There's a Berserk Powerup here. Don't forget to use the chainsaw if you're
low on ammo.
Post Fight: on the way up to the waypoint (a Wraith's Soul), there's a
bunch of supplies. On the left stairs going up, look for a big hole in the
upper half of the stairs that's so big you can walk in under the stairs.
This is SECRET 13.1, COLLECTIBLE 13.1: "Chaingun Model, Cosmoguy".
Continue up to interact with the waypoint, then follow the waypoint to the
next fight.
You'll teleport to an area with molten rock. At you walk up this tunnel,
keep an eye out for the third Skull Switch, on the right. Interact, then
walk back toward the entrance to find an newly opened alcove, SECRET 13.4,
containing Meta Health and BFG Ammo (don't forget to activate Rich get
Richer before taking the health).
Mission 13: Fight: Wraith Fight 3
Again, snipe a Hell Knight and an Imp before jumping down, if possible.
This fight is a long sequence of Hell Knights and Pinkies and Imps. Toward
the end a Cyber-Mancubi and finally 2 Hell Barons- you're easiest chance
to get the Hold Still Challenge (use the BFG of course).
Post Fight: gather supplies and interact. Follow the waypoint to the last
fight, a boss fight.
Mission 13: Boss Fight: Spider Mastermind
This is your big battle with demonic Olivia Pierce.
Unlike the other boss fights, this one doesn't have a checkpoint in the
middle.
The first phase of the fight, is pretty standard:
* Rocket Volley: a fast sequence of rockets. Keep moving in one
direction to dodge.
* Back-And-Forth Laser: a red laser that swipe one direction low (so you
must jump over it) then it swipes back high, so you must crouch under
it.
When the demon gets to 50% health, she'll add:
* Toxic Pond: Pillars sprout up that you must stand on, as the ground
will be very damaging to stand up. The first time, that's all that
happens. Subsequent times, Olivia will concentrate on the pillars, and
when she jumps spikes will come out of the pillars, killing you if you
are standing on them. Double jump in the air to avoid this fate.
When she gets to around 10% health, she kind-of goes nuts, shooting many
(fairly weak) lasers in all directions, and emitting these weird cubic
missiles that do a lot of damage (dodge them).
When she gets to 0% she'll stand up like she's going to attack or
something, but she actually flops down and is Glory Killable. (There's no
time limit, she won't recover from being staggered)
You'll get COLLECTIBLE 13.2 "Spider Mastermind Model, Goldguy", along with
6 Weapon Upgrade points.
After that, watch a cut-scene and the credits.
