A1.1 -- INTRODUCTION
---------------------
Back in 1992 with the ALIEN 3 film was released in movie theatres a number of
game developers also released their games based off the movie. Most of them
went with a common enough formula involving a time limit and freeing all the
prisoners on each level. The Super Nintendo version was a bit more complicated
and turned the game into a series of small missions to complete. The Game Boy
version was the most different of them all. Instead of a side-scrolling
platformer, the game focused on a top-down overview where the prisoners
resembled target practice for the aliens (rather than captured victims) and the
game is more puzzle-oriented.
In this variation of ALIEN 3, an infestation has broken out on the prison
planet, complete with eggs and even a Queen and Ripley must neutralize this
threat single-handedly while keeping as many prisoners alive as possible and
before the company arrives to capture them.
Initially, you start off with no weapons and no equipment. You must navigate
your way through the various levels and air ducts in-between to arm yourself
with weapons, key cards and other tools to help prepare yourself for a brutal
fight with the aliens.
You start the game with three tries. Each time you are drawn into a fan or
have your health depleted, you will lose a try. After losing a try, you will
start back in your quarters on Level 1, but beware: If there are no prisoners
left alive and you lose a try, it's a game over, no matter how many tries you
have left, since no one is alive to find you.
At the end of a game, you will receive a score based on how well you performed.
* Normally, "Facehugger" is spelled as one word, but in this game, the word
is split into two. This guide will refer to the creature by how it is
pronounced in the game.
A1.2 -- HOW TO PLAY
-------------------
At the title screen, press [START] to start a game.
During all cutscenes, you can press [A] to advance to the next scene or [START]
to skip the entire thing. All timers are paused during cutscenes.
-- On the field.
Directional Pad - Move around the screen.
[A] - Use equipped inventory.
[B] - Use equipped weapon.
[SELECT] - Bring up the menu.
[START] - Pause the game. Pressing [START] again will resume the game.
-- Menu
Direction Pad - Move an arrow around the screen to hover over items.
[A] - Pickup / Drop an item.
- If hovering over an equipped item, a description will appear.
- If hovering over "EXIT", you will return to the game.
[B] - Equip an item.
[SELECT] - Return to the game.
To open a door, get close enough to one and press [A] to open it. Some doors
require a key (and one requires the Blow Torch). Make sure the appropriate
item is equipped, then press [A] to open the door.
To trigger switches in an Air Duct room (and Level 3) appear as small buttons
along a wall. Make sure you are standing close enough to it so your inventory
selection (on the main screen) is replaced with an on/off switch. Press [A]
to toggle the switch.
Attacking enemies requires both a weapon and ammo. The Cattle Prod does not
require any, but all the other weapons do and it is limited (Albeit plenty).
Equip a gun on the menu screen. After a brief period to 'load' the weapon, you
will be ready to fire. Each Gun Clip gives an ammo count of 60 (Yes, even the
Pistol). When that count reaches zero the gun will take a second to
automatically reload. The Flame Thrower uses Fuel instead of Gun Clips. Each
fuel unit gives you four flame pellets.
A1.3 -- PICKING UP & DROPPING INVENTORY
---------------------------------------
Hit [SELECT] to bring up the menu.
All items in the game (With the exception of 3 hidden ones) appear as dots on
the main screen. When you stand near a dot, the item should be available along
the "SEE" row on your menu screen. Press [A] to add an item to your inventory.
- Weapons will be moved to your "Weapons" column. These cannot be unequipped.
- Gun Clips and Fuel Refills will disappear.
- All remaining items will be moved to your "Inventory" column. you can only
carry a maximum of five items.
- To equip an inventory item/weapon, select the item with [B]. You can unequip
an item/weapon by pressing [B] over an empty slot.
- You can drop whatever you do not have currently equipped by selecting the
item with [A].
- To see what an item is called, press [A] while it is equipped.
A1.4 -- LEVELS
--------------
There are four levels to explore: The Surface Level and Levels 1-3. Each
level starts off with prisoners only, but after a little while, aliens will
start appearing, attacking everyone in their path, including you.
Alien appearances are:
Surface - Aliens, 1 at a time
Level 1 - Face Huggers, 3 at a time
Level 2 - Warriors, 2 at a time
Level 3 - Queen. All eggs and aliens must be destroyed for her to appear.
A1.5 -- AIR DUCTS
-----------------
There are five different Air duct rooms, each one connects the player from one
level to another and in some cases to an Alien Nest.
There are no enemy encounters, but the fans are dangerous to Ripley's health.
If she gets pulled into one, you lose a try.
There are various switches scattered around each Air Duct room. These turn
fans on/off or change their direction. In many instances, this is useful in
blowing you away from the fan, but there are are instances being blown into a
fan is necessary for accessing a path that appears before it, giving you a
small window to enter path before getting sucked in.
How to tell which was a fan is blowing:
Vertically - Left side
Horizontally - Bottom side
In Air Duct 4 and 5 there are walls with live circuits. Contact with them will
cost you a try. Take extra case as a couple fans can blow you into them.
A1.6 -- ALIEN NESTS
-------------------
Alien Nests tend to be dangerous places because of the eggs. While harmless if
you keep your distance, they can do serious damage if you get too close.
Rooms 1, 3 and 5 will contain facehuggers and prisoners.
_______________________________________________________________________________

/-| |_ | |_ | \|
_______________________________________________________________________________
You have 5 minutes before Face Huggers appear and 6.6 minutes before all hell
breaks loose. Get moving!
B1.1 -- Level 1, Key Card 1 & Map.
----------------------------------
Path: Level 1
You will start the game in your quarters (This is also the place you will
re-spawn should you lose a try). In the upper-left corner of the room is the
Cattle Prod. It is up to you if you want to take it, but this weapon is
responsible for the Ammo Consumption Glitch (See Section C1.2 for more
details).
Exit the room and head down at the 1st junction, then turn right at the next
one, following to path all the way to the far right. At the end you should see
a item dot near an open door. That is Key Card 1. Grab it. You will need it
to unlock a couple doors.
* This next part you can do now or later when you go "On the hunt" since this
is the only time in the game when you do not have to deal with the
infestation.
Go left to where you first came down the junction, but keep going left. You
will see a locked door below you. Equip Key Card 1 and open the door. Head to
the bottom of the room and pick up the Map. This item is entirely optional,
but it is useful in giving you important enemy stats.
B1.2 -- Level 2 & Key Card 2
----------------------------
Path: Level 1 -> Air Duct 1 -> Level 2
Head back up to the first junction outside your quarters and go right. Above
you will be an entry into the first Air Duct 1. Head in.
** See Air Duct 1 Solution for how to cross to Level 2.
Once in Level 2, head left, down into the corridors and left again. The first
door above you requires a Key Card 3, so leave it alone for now. At the end
of the corridor is a T-junction. Head down into what looks like a storage
area. There are two boxes that are darker in colour. The one along the far
right has Key Card 2. Grab it.
Head back up.
* This next part is optional, assuming you are fast enough to avoid getting
caught in the middle of an xenomorph infestation unarmed. You will be
heading back this way.
Equip Key Card 2 and open the door. Grab the Pistol and two Gun Clips. You
cannot get through the next door, but if you attempt to open it, you will be
directed to the scrap heap, which is on the Surface Level.
B1.3 -- Blow Torch and a Better Weapon.
---------------------------------------
Path: Level 2 -> Air Duct 1 -> Level 1 -> Air Duct 2 -> Surface Level
Head right and back up to re-enter Air Duct 1.
** See Air Duct 1 Solution for how to cross to Level 1.
Make sure you have at least one open slot for the Blow Torch. You could leave
a Medi Kit by your quarters, if you wish.
Head down, right and follow the winding path around until you reach a locked
door. With Key Card 2 equipped, it will open. Ignore the first door on the
right (It leads to an Alien Nest) and continue down to the second door on the
right. Equip Key Card 1 and enter Air Duct 2.
** See Air Duct 2 Solution for how to cross to Surface Level.
Once you have arrived on the Surface Level, head right and go down along the
winding corridor. Ignore the the first chance to go up and take the second
one. You will arrive at the scrap heap. There is a lot of stuff to pick up
here.
- Start with the dot closest to you and get a Fuel Refill.
- You cannot go around the left side, so go around the right and stop at the
top-right corner of the room along the wall. Look to your right and pick
up a Pulse Rifle (This item is hidden). Make sure you do not miss this
weapon. It is the 2nd best one for picking off aliens, next to the Smart
Gun.
- Move towards the top-middle of the scrap heap and pick up two Gun Clips.
- Along the top-left corner of the scrap heap you can find the Blow Torch
(This item is hidden).
* the Damaged Droid can be found on this level, but there is no reason to move
him since you need him at the exact spot you find him at the end of the game.
* You have everything you need to get Key Card 3 right now, but there are a
couple problems: The Key Card lays in an Alien Nest and there is an Air Duct
along the way. You cannot destroy eggs yet and one blocks the path to the
key card. You will take considerable damage (or possibly lose a try) just
trying to get to the card, and more damage while heading back out. Even if
you do grab the card, you will still have to come back and deal with the eggs
after obtaining the Flame Thrower.
B1.4 -- Flame Thrower and Marshmallows
---------------------------------------
Path: Surface Level -> Air Duct 2 -> Level 1 -> Air Duct 1 -> Level 2
The path to the right leads to a dead end, so head down and make your way back
to Air Duct 2 (Down, left, ignore first up, go through 2nd up, ignore 3rd up
and go through the door to the left).
** See Air Duct 2 Solution for how to cross to Level 1.
Head up, equip Key Card 2 to open the door and make your way back to Air Duct
1.
Head left, down and left again, go along the long corridor and head up to get
into the armory. Use Key Card 2 on the first door and the Blow Torch on the
second door.
* If you have been skipping all the optional items and paths you can take, this
should be about the time when the Face Huggers first appear. You will get a
message about the Warden (Dillon calls him Cap'n) getting killed.
Enter the armory and grab the Flame Thrower and Fuel Refill. If you did not
pick up the Pistol and Gun Clips, be sure so grab them on the way out (Or at
least the clips if you already have the Pulse Rifle).
B1.5 -- Egg Extermination and Key Card 3
----------------------------------------
Path: Level 2 -> Air Duct 1 -> Level 1 -> Alien Nest 1 -> Level 1 ->
Alien Nest 2 -> Level 1 -> Air Duct 2 -> Surface Level ->
Air Duct 3 -> Alien Nest 3
You may notice there is a lot of going back and forth between Level 2 and the
Surface Level. This guide suggests you get used to it; it will continue to
happen until the very end of the game.
Exit the armory, head left and make your way back through Air Duct 1. You can
discard the Blow Torch, if you wish. You will no longer have a use for it.
There are two Alien Nests on this level. Given that the eggs spawn the various
aliens that appear on different levels, it is in your interest to stop this
from happening. Also, if you have not seen them by now, Face Huggers should
be appearing on this level.
* If you have the Pulse Rifle, you can take them out quickly with three shots.
* If you have the Pistol, you can take them out slowly with four shots.
* If you have the Cattle Prod, you can look forward to losing a lot of health
(But a good couple shots will take one out). Unless you want the extra
challenge or have somehow managed to miss all other weapons in the game, you
should take out all aliens from a distance.
Make sure you have an open slot for Key Card 3.
After exiting Air Duct 1, head left and down.
* If you have not picked up the Base Map yet, now would be a good time so you
can track how many aliens and eggs are left. Go right, use Key Card 1 on the
door and head into the room. The Base Map is near the bottom-right corner of
the room.
Head right and go down the first chance you can. Go right and into the Alien
Nest 1. Face Huggers and prisoners will appear in here, so start torching the
eggs as soon as you can. There are five of them in this room.
Once you are done, head back out and backtrack to Air Duct 2 (Go left, up,
left, up, right, down and around the winding path). After you use Key Card 2
to open the door, go to the first door on your right. It leads to Alien Nest
2. No Face Huggers will appear in here, so calmly get out your Flame Thrower,
destroy the eggs present and exit.
Head down to the next door and use Key Card 1 to cross through Air Duct 2.
By now, you will see the large Aliens roaming throughout the level. With your
Pulse Rifle, they require six shots to take out. If you do not have it,
evading them would be the safer course of action.
Head right, down and continue along the linear path until you head up.
Continue along that path and you will reach a locked door. Equip Key Card 2
and enter Air Duct 3
** See Air Duct 3 Solution for how to cross to Alien Nest 3.
Entering the Nest, there is egg blocking the path to the other side of the
room. Take a Flame Thrower to it and every other egg you see in the room.
Head around and up and pick up a Key Card 3 along the top left corner. There
is also a Medi Kit here if you want to take it with you / use.
B1.6 -- Egg Extermination and the Best Weapon
---------------------------------------------
Path: Alien Nest 3 -> Air Duct 3 -> Surface Level -> Air Duct 2 -> Level 1 ->
Air Duct 1 -> Level 2 -> Air Duct 4 -> Level 3 -> Air Duct 5 ->
Alien Nest 4 -> Air Duct 5 -> Level 3 -> Alien Nest 5
Three nests down, two to go, but they will continue to produce aliens. You are
not done yet.
Leave the Nest and head back into Air Duct 3.
** See Air Duct 3 Solution for how to cross to Surface Level.
Once you are back on the Surface, head down, down again, turn left, follow the
path and enter the door along the left side to go through Air Duct 2
* Once you are through Air Duct 2, if you want, you can leave Key Card 1 by the
door to Air Duct 2 since you will only need to use it one more time.
Head up, equip Key Card 2 to open the door and make your way back through Air
Duct 1.
If you want, you can kill any aliens along the way, but the goal is the door
between the entrance to Level 2 and the armory; the door that requires Key
Card 3 to unlock. Go down, left, down, left and use Key Card 3 on the 1st door
you see. Enter Air Duct 4.
** See Air Duct 4 Solution for how to cross to Level 3.
For the time being, Level 3 is safe to go through. Go down, right and up
through the first door you see to enter Air Duct 5
** See Air Duct 5 Solution for how to cross to Alien Nest 4.
Like Alien Nest 2, there are three eggs and no Face Huggers in sight. Calmly
torch them with your Flame Thrower, grab the two Gun Clips and Fuel Refill and
exit the room.
** See Air Duct 5 Solution for how to cross to Level 3.
Once you are back in Level 3, head as far left as you can and down. There is a
Tool Kit in the bottom-left corner. If you have a slot for it, grab it. Head
up along the path until you reach the upper-left corner and go through the door
leading to Alien Nest 5
* Try to grab the Repair Kit now, rather than waiting for later. This is the
easiest opportunity to obtain it.
* There is a Knife in the upper-left corner of the room. It does not appear to
have any use in the game but it can be found near a grate with a large pool
of 'something' nearby.
There are three eggs inside plus the best weapon in the game: The Smart Gun.
Torch the last three eggs then equip the gun.
B1.7 -- Total Extermination!
----------------------------
Path: Alien Nest 5 -> Level 3 -> Air Duct 3 -> Level 2 -> Air Duct 1 ->
Level 1 -> Air Duct 2 -> Surface Level
With all the eggs destroyed, the aliens can no longer reinforce their numbers.
Now is the time to pick off all the ones that have spawned.
* Face Huggers appear in Level 1 and Alien Nests 1, 3 and 5
* Warriors appear in Level 2
* Aliens appear in Surface Level
You can start in this room, since Face Huggers will regularly appear until you
have eliminated all of them. Luckily, with the Smart Gun, they only need one
shot each.
Once you are done, exit the room, head right and up and enter Air Duct 4.
** See Air Duct 4 Solution for how to cross to Level 2.
Level 2 is filled with Warriors. They take two shots each from the Smart Gun.
Stick around and clean house. Once you are done, head through Air Duct 1.
Level 1 should already be clear, assuming you took care of all the Face Huggers
in Alien Nest 5. Head through Air Duct 2.
On the Surface Level you will come across the full-size Aliens. They require
three shots each to take down. Once they are all dead, you should get a
message about Ripley wanting to take down the Queen. If not, you missed
something, somewhere. If you have the Base Map with you, you can check to see
what you missed.
* If you grabbed the Repair Kit already, you can leave it by the EEV. If you
missed it, grabbing it will now be a lot more difficult.
B1. 8 -- She is the Queen!
--------------------------
Path: Surface Level -> Air Duct 2 -> Level 1 -> Air Duct 1 ->
Level 2 -> Air Duct 3 -> Level 3
All that remains is the Alien Queen. Head back to level 3.
Once you arrive, it won't be long until you come across an extra-large alien
creature. This is the Queen and deadliest of all enemies. It is invulnerable
to all your weapons and the slightest touch is enough to kill. Don't let it
get close to you under any circumstances.
* If you have not picked up the Took Kit yet, now would be a good time, despite
the Queen being active. If you wait until after the Queen is dead, you will
have to do a LOT of backtracking.
To kill the Queen, you need to maneuver her in front of a moving tram and force
it into the furnace. To do this you need to get the tram started. Head down,
go left and the 3rd up (1st one after the tram lane). Go up to and press the
switch to get it started.
There are two ways you can handle this scenario:
* The safest way is to stay on the tram lane. The Queen does not spawn on the
lane, so you can stay behind the tram as it slowly works it's way to the
furnace. Along the way, the Queen may appear on the path below and "If" you
are lucky you can catch the Queen at the exact moment the tram crosses the
other path, keep it from moving down along the screen and finally push it
into the furnace. While it is a fairly safe method, it could take a lot of
tries to accomplish.
* The more dangerous (but more likely to succeed) way is to backtrack along the
path and use yourself as bait for the Queen to spawn near the tram lane. Try
to keep it on the screen at all times and keep it following you into the
lane. If it tries to escape, give chase until you get it's attention again.
Eventually the tram will pin it in the lane and push it into the furnace.
Fortunately the walkways along either side of the furnace are small enough
for Ripley to walk enough, but not the Queen, leaving you with a safe zone if
the Queen follows you right into the furnace.
After the Queen has been pushed into the furnace, the hardest part of the game
is over.
B1.9 -- Get Out of Here!
------------------------
Path: Surface Level
Once the Queen is dead, you will be automatically taken to the EEV on the
Surface Level.
* All in-game timers have stopped. You no longer have a limited time to
complete the game.
Add the Damaged Droid and Tool Kit to your inventory and equip the Tool Kit.
Use it to repair the droid, then equip Bishop Synthetic. You will get a
cutscene showing he is operable again. Use him again and if you are close
enough to the EEV to operate, followed by a cutscene showing the (somehow)
repaired EEV taking off.
And... That's it. You have beaten the game. Congratulations!

_______________________________________________________________________________
C1.1 -- GAME OVER
-----------------
The following events will end your game, either immediately or prevent you from
winning:
Game Over:
- Run out of tries.
- Out of ammo, no ammo drops left and xenomorphs are still present.
- Out of fuel, no fuel drops left & eggs are still present.
- Equip a cattle prod (or glitch another non-ammo inventory item) & no ammo
drops left. This appears to be a glitch in the game (See below for more
details).
- Lose a try and the prisoner count is 0, even if you still have some
remaining.
- Weyland-Utani arrives. Time is up.
- Escape the planet on the EEV.
Events that can prematurely end your game:
- Dropping Key Cards in places after they are used then leaving them without
taking them along with you (Either by exiting the area or losing a try and
re-starting at your quarters).
Notes:
- It is okay to run out of Flame Thrower fuel if all the eggs have been
destroyed.
- It is okay to run out of ammo if all the aliens (Save the Queen) have been
killed.
C1.2 -- GLITCHES
----------------
(This an an excerpt from the article I wrote for "The Cutting Room Floor")
-- NO AMMO GLITCH
There is a glitch that happens when you equip a non-ammo-consuming weapon and
there are no more Gun Clip pickups available. For this to happen:
- The Cattle Prod must be part of your inventory.
- All seven Gun Clips must be picked up.
When this happens, you will automatically get a Game Over, even if you still
have ammo for weapons. There is a counter that tracks how many ammo pickups
there are. Normally, when that reaches zero and you are completely out of ammo,
you get a Game Over. When equipping the Cattle Prod, your current ammo and
current clips values are both set to zero (The data is also kept on another set
of bytes that are related to the menu screen). The game only appears to look at
the current values and not the menu values, which triggers the premature Game
Over.
This bug becomes null and void once all the xenomorphs (save the Queen) have
been eliminated, since the check is no longer in place. The same check also
applies to Flame Thrower fuel and Eggs.
-- INVENTORY DROP GLITCH
There is a byte in the game that tracks how much 'stuff' is in a room
(Inventory you can pick up, prisoners & aliens on the screen, projectiles, etc.
). The value raises or drops by 4 (Some inventory items count as 8) depending
on what is active, has been picked up. When the byte reaches 0x9C, the room has
reached maximum capacity and nothing else can be added.
The glitch occurs when you pick up an item. The byte does not decrease when you
pick up an item, but it will increase when you drop one. It is possible to keep
picking up and dropping an item to reach 9C, at which point you will receive a
"TOO MUCH STUFF" message and will no longer be able to drop anything.
This is not permanent and there are a couple ways to clear this value. Both of
these reset the byte to it's proper value:
- Exit and re-enter a room.
- Wait for a prisoner / alien to leave the room.
You can also fire your weapon, though this sets the byte to a very low number
until something else resets it.

C1.4 -- INVENTORY
-----------------
The order is based on the ID numbers provided above:
CATTLE PROD
- Location: Level 1, in your quarters.
- Damage: 2 per 'tick'. Can kill a Face Hugger with 2 good hits.
- Requires: Nothing
Your first accessible weapon. Unless you prefer the challenge, it is quite
unnecessary. In addition, this weapon is responsible for the Ammo Consumption
Glitch (See Section C1.2 for more details). So long as you do not have it, you
need not worry about a premature Game Over.
PISTOL
- Location: Level 2, in front of the welded Armory door.
- Damage: 8 per shot.
- Requires: Gun Clips
Your first range weapon. It does little damage and has a slow rate of fire,
but it is better than nothing. It can be used effectively against Face Huggers
and somewhat against Warriors, if necessary. The number of shots required to
kill a full-size Alien combined with it's slow rate of fire makes it a poor
weapon to use against them.
PULSE RIFLE
- Location: Surface Level, by the scrap heap, along the top-right corner wall
of the room. It is one of three hidden items.
- Damage: 12 per shot.
- Requires: Gun Clips
Your first 'good' range weapon. While it does not do much more damage than a
Pistol, the rapid-fire ability more than makes up for this, allowing you to
quickly gun down any enemy along the way without too much trouble. While it is
not consumption-friendly, this will help you get to the final gun without too
much trouble.
If you follow the walkthrough and make good time getting to the scrap heap,
this should be the first weapon you make an effort to pick up, giving you
something useful before the aliens start spawning.
FLAME THROWER
- Location: Level 2, Armory
- Damage: 1 per pellet. Sometimes a pellet will hit twice.
- Requires: Fuel Tanks
The Flame Thrower works more as a puzzle solver rather than a useful weapon. It
is the only weapon capable of destroying eggs, but it's low damage makes it
next to useless against other alien types.
SMART GUN
- Location: Alien Nest 5, surrounded by Eggs.
- Damage: 30 per shot.
- Requires: Gun Clips
A late, but powerful weapon. The damage per shot, combined with the timing of
dealing with all the eggs (If you followed the walkthrough) makes it an ideal
extermination weapon.
KEY CARD ONE
- Location: Level 1, by an open in the middle of the level.
- Function: Opens the door to the Base Map room and Air Duct #2
- Requires: Nothing
One of the first items you should pick up. You will need it regularly as you
keep re-visiting the surface level.
BISHOP SYNTHETIC
- Location: N/A
- Function: Operates the EEV (Ending the game).
- Requires: Tool Kit and Damaged Droid.
This is not available until you have picked the Tool Kit and used it to repair
the Damaged Droid.
If you attempt to use Bishop to pilot the EEV before you are done cleaning up
the prison, he will inform you of the company's intentions to capture a living
alien and that you should deal with all the aliens and Queen before leaving.
BASE MAP
- Location: Level 1, bottom-left room.
- Function: Shows a map of where you are and game stats.
- Requires: Key Card 1
Once you have collected the Base Map, you can equip it and use it to view the
map of the current floor you are on, plus various information about the prison.
P - Prisoners still alive.
T - Time until Weyland-Yutani arrives (ending your game)
A1 - Aliens
A2 - Warriors
H - Face Huggers
E - Eggs
KNIFE
- Location: Level 3, upper-left corner.
- Function: Currently unknown.
- Requires: Nothing
The Knife does not appear to have a functional use. The only curiousity about
the item is it is located by a long trail of dark liquid (Possibly blood)
leading to a grate in the floor.
MEDI KIT
- Locations:
- Air Duct 1
- Air Duct 2
- Air Duct 3 x2
- Air Duct 5
- Alien Nest 3
- Function: Recovers 150 health.
- Requires: Nothing
Medi Kits recover 4 1/2 blocks of health (or 150 out of 255).
GUN CLIP
- Locations:
- Surface Level x2
- Level 2 x2
- Alien Nest 4 x2
- Alien Nest 5
- Function: Adds three gun clips to your ammo capacity.
- Requires: Nothing
Gun Clips are the core component of your ability to shoot things. Very
necessary to acquire.
As you can see, there are seven Gun Clip pickups. Given there is more than
enough ammo to finish the game, if you leave one clip on the ground, you will
not have to worry about the Ammo Consumption Glitch if you picked up the Cattle
Prod.
FUEL REFILL
- Locations:
- Surface Level
- Level 2
- Air Duct 2
- Air Duct 4
- Alien Next 4
- Function: Adds two fuel tanks to your fuel capacity
- Requires: Nothing
Without Fuel for your Flame Thrower, the eggs will never be eliminated.
KEY CARD TWO
- Location: Level 2, in the storage area below the Armory. It is in the
darker crate on the right. It is one of three hidden items.
- Function: Opens the doors to the Armory, the east rooms on Level 1 and
Air Duct 3.
- Requires: Nothing
Should be the first thing you obtain when you first visit Level 2.
KEY CARD THREE
- Location: Alien Nest 3, deep within the infestation. At least one egg
directly blocks the path to it.
- Function: Opens the door to Level 3.
- Requires: Key Card 2 and Flame Thrower
Do not forget to pick it up on your way out of the nest.
BLOW TORCH
- Location: Surface Level, along the top-left corner of the scrap heap. It
is one of three hidden items.
- Function: Opens the door to the Armory on Level 2
- Requires: Nothing
You will need to search around the scrap heap to find it.
TOOL KIT
- Location: Level three, bottom-left corner
- Function: Repairs the Damaged Droid
- Required: Nothing
The first time you are in Level 3 is the best time to obtain this item. Once
all the eggs and aliens are dead, the Queen will roam Level 3 which will make
grabbing this more difficult. Also, if you wait until the Queen is dead, you
will have to backtrack from the Surface Level all the way back here to get it.
DAMAGED DROID
- Location: Surface Level, by the crashed EEV.
- Function: Until it is repaired, nothing.
- Requires: Tool Kit to be fixed.
Bishop is in a damaged state and needs repairs before you can do anything with
him.
C1.5 -- PRISONERS
-----------------
Prisoners are treated like a resource and are tied in to both your tries and
your final score.
- A prisoner can take 2 hits from anything, ranging from the Face Hugger up
to a Queen (Yes, the same Queen that can kill you instantly). Typically,
after getting hit, a prisoner will run around on the screen a lot faster.
On the 3rd hit, the prisoner will die.
- The time between hits is very small. If the alien stays around the
prisoner while they keep getting hit, they can die rather quickly.
- Prisoners are unaffected by alien splatter and eggs.
- To keep prisoners alive, it is recommended you stay on the move while you
engage the aliens. So long as a prisoner is removed from the screen before
they are hit for a third time, they will be fine. This will be a lot more
difficult to do in Alien Nests, given how small they are, limited room to
navigate and often infested with Face Huggers.
- If you lose a try (Loss of health or run into a fan, live wire, etc.), at
least one prisoner must still be alive to 'find' you or else it's a Game
Over, regardless of how many tries you still have left.
C1.6 -- MISSION SCORE BREAKDOWN
-------------------------------
At the end of a play-through, you will get a score based on your performance.
There is no bad or good ending, simply a score reflecting how much effort you
put into a game.
Aliens Killed:
- Face Huggers +500 pts. each
- Warriors +1,000 pts. each
- Aliens +2,000 pts. each
- Eggs +400 pts. each
Specific Events:
- Queen Killed YES = +100,000 pts.
- Prisoners Alive +100 pts. each
+3000 pts. each "IF" Queen is dead
- EEV Lift Off YES = +50,000 pts.
- Tries Remaining +500 pts. each
Only the above affect your final score. What equipment you have picked up and
used, time remaining, etc. do not contribute.
C1.7 -- TIMERS AND ENEMY SPAWNING
---------------------------------
Timer Time:
- 2 bytes.
- 1st byte rapidly increments from 0x00 - 0x31 before cycling. (50 ticks)
- 2nd byte adds one every time 1st byte cycles. When the 2nd cycles cycles
from 0x31 - 0x00, timer deducts one minute from the time. (50 x 50 ticks)
1 Game Minute = 2500 'ticks'.
Alien Time
- 2 bytes.
- 1st byte cycles from 0x00 - 0x63 before cycling. (100 ticks)
- 2nd byte adds one every time 1st byte cycles.
- When 2nd cycles cycles from 0x27 - 0x00, another wave of aliens has spawned.
(40 x 100 ticks)
1 Alien Spawn = 4000 'ticks'.
Based off the 1st timer, an alien wave will spawn every 1.6 game minutes. The
size of the wave will be four Face Huggers, two Warriors, one Alien and a
multiplier based on the number of eggs remaining:
1-3 - x1
4-7 - x2
8-11 - x3
12-15 - x4
16-17 - x5
Example:
1.6 game minutes after you get the message that the aliens are on, 20
Face Huggers, 10 Warriors and 5 Aliens will spawn unless you managed to
destroy at least two eggs once the timer starts.
Taking out eggs as you go along does slow the progress of new aliens appearing.
After five minutes, when the "Start Alien Spawning" byte is set to 0x01, the
game will add eight Face Huggers to the pool. After the first interval, all
three alien types will appear.
C1.8 -- TIMED NOTICES
----------------------
There are a couple messages that appear at specific times through the game:
2:28
- First message from "Rumor Control"
2:25
- Alien Spawn is triggered. If Ripley is still unarmed, she will receive
directions to go to the armory.
2:10
- Message about the EEV.
C1.9 -- ENEMIES
---------------
Note: A 'tick' does not refer to a second, but 1/2500th of a Game minute.
Approximately 41.7 ticks would be a game second.
Face Hugger
- HP: 30
- Score Value: 500 pts.
- Damage: 1 per 'tick'. Kills with approx. 6.1 seconds of constant contact.
- Room Spawn: 3 at a time.
- Maximum Spawn: 60
- Appearances: Alien Nests 1, 3 and 5 & Level 1.
Fortunately, Face Huggers do not behave like their canon counterparts and
actively try to latch onto Ripley's face. Instead, they behave as tiny aliens
and are the least-threatening of all the enemies. The only advantage they have
is they spawn in groups of three and have the potential to surround the player
if one is not careful.
Also, given how many can appear in a room, they are the most effective enemy at
killing prisoners.
Face Huggers can be killed with any weapon without too much difficulty. The
Cattle Prod can be used to take one out quickly, but expect to take some health
damage. The Flame Thrower is ill-suited for taking out any aliens, given it's
low damage, but if you do decide to use it, Face Huggers are your best bet.
Warrior
- HP: 50
- Score Value: 1,000 pts.
- Damage: 4 per 'tick'. Kills with approx. 1.5 seconds of constant contact.
2 per 'tick' post-explosion.
- Room Spawn: 2 at a time.
- Maximum Spawn: 50
- Appearance: Level 2
While not at the threat level of a full-sized Alien, Warriors are still
dangerous foes, especially since two can appear two at a time. They move
around quickly and leave behind a small mess when they are killed which can
further drain the player's health. Always keep your distance from these
monsters, when possible.
Do not waste your time using the Cattle Prod and Flame Thrower. Pistol is slow
at killing one (and takes a lot of ammo), but it's still possible if necessary.
Pulse Rifle and Smart Gun and both good and taking care of them, given their
rapid-fire ability.
Alien
- HP: 70
- Score Value: 2,000 pts.
- Damage: 6 per 'tick'. Kills with approx. 1 second of constant contact.
3 per 'tick' post-explosion.
- Room Spawn: 1 at a time.
- Maximum Spawn: 40
- Appearance: Surface Level
The full-size Aliens are a considerable threat if not handled carefully and
taken seriously. They are quite large, able to quickly drain your health, take
a lot of firepower to kill and are prone to short bursts of speed while moving
around.
Unless you are using a Pulse Rifle or Smart Gun, it would be wise to avoid a
fight with one, altogether. When you must engage them, try to stay along the
top of the map, near the crashed EEV. You will have a lot more room to move
around and dodge the Alien as necessary.
Queen Alien
- HP: N/A
- Score Value: 100,000 pts.
- Damage: 50 per 'tick'. Kills near-instantly.
- Room Spawn: 1 at a time.
- Maximum Spawn: 1
- Appearance: Level 3
The Queen Alien is akin to a final boss in this game. She is invulnerable to
all your weapons and the odds of surviving physical contact with her is not
impossible, but extremely unlikely. Stay away from her at all costs.
Egg
- HP: 5
- Score Value: 400 pts.
- Damage: 10 per 'tick'. Kills with approx 0.6 seconds of constant contact.
- Room Spawn: Dependent on the room.
- Maximum Spawn: 17
- Appearance: All Alien Nests
These eggs are small and harmless so long as you stay away from them. They
have 5 HP, but can only be damaged with Flame Thrower.
Their 'damage' box is not perfectly centered. It is considerably off to the
right (Meaning you can get a lot closer to the left side of an egg than the
right without taking damage).
Notes:
- There is actually a byte that shows a decrease in value when the Queen is
shot by a weapon, but it decreases by a fixed amount (around 32?) and
cycles back up to around 14000 when it reaches zero.

D1.2 -- FAQs
------------
Q: Where do you get your information on what to do in the game? Is it through
the manual?
A: The manual gives you a basic idea of what to do, but lacks giving specific
directions. It is more useful in telling you how to play, plus partial
information on what you will encounter.
You can get directions through the game itself. For instance:
* After five minutes and the aliens start appearing, if you are still not
carrying a gun Ripley will ask if there are any weapons. You will be
directed to the armory and you will be informed of a required key card that
can be found in a crate on the same level.
* If Ripley tries to open the 2nd armory door without a Blow Torch, you will
get information on where it is located (The scrap heap) plus what is inside,
namely the Flame Thrower.
* After twenty minutes, Ripley will ask Dillon if there is some means of
escaping the planet. He will mention the EEV Ripley crashed in, but she will
need to find the means to launch it on her own. This gives direction to the
player that there is an objective to escape the planet.
* Once Bishop is repaired with the Tool Kit, he can help Ripley pilot the EEV.
However, if there are any aliens still left on the planet, he will advise
Ripley to exterminate them all to lure out the Queen and deal with her before
leaving.
* After all the aliens are dead (Save the Queen), Ripley will talk to Dillon
about luring her into the furnace and pushing her in there with the tram.
D1.3 -- FINAL NOTES
-------------------
Originally, I was looking through this game for glitches and bugs, rather than
doing up a walkthrough with some internal game data, but one thing led to
another and this is the end result.
I can still recall playing this one on my old Game Boy and how frustrating it
was (initially) until I figured out where some of the important stuff was, like
the Blow Torch (which does not appear on the map).
Overall, I would say it was not a bad game for the handheld, even on a spinach-
coloured screen.
