INSTRUCTIONS | Codes by bungholio from CMP

To make these work for CodeUnique, add exactly 00010000 to the address of these codes. I tested all of them with CodeUnique for once in my life, and they all worked just fine.

Checkpoints Are Made Nonstop
0034561C 2F800000
ORIGINAL PATTERN: 801F0024 2F8003E7
PATTERN: 801F0024 2F800000
If you are killed by an enemy, you will restart right then and there and your health will refill. As long as you don't do something like jumping into a pit of lava a mile down, this should get you through any level. This also works on the hardest difficulty.


Aliens Have Trouble Moving Around
0039B998 2F800000
ORIGINAL PATTERN: 2F8003E7 419E0048 E80101D0
PATTERN: 2F800000 419E0048 E80101D0
They attempt to slowly hop to you, and when they get close they usually are stuck hopping and can't attack. If they do attack, back away and they'll be stuck hopping again. It makes it very easy to run past them. I haven't had the chance to try this around anything other than normal xenomorphs, so it might do nothing for androids, predators, facehuggers, queens, the big xenomorph, soldiers, or other things.


Partial Invincibility
005D7444 60000000
ORIGINAL PATTERN: C15E0038 ED4A02B2 EDAB02F2 D1610080 D181007C D0010084 ED8C6B3A EC00603A FF805000 409D0008

I'm not certain of how this works, but I have only tried it as a marine against aliens. They will swing at you and always miss somehow. As long as you don't melee them back or block their strikes, it will stay that way. I can't figure out how blocking or meleeing them back causes this to no longer work, but I never had a problem with slowly shooting them to death with a pistol.


Any Damage Instantly Kills
00368874 48000008
ORIGINAL PATTERN: FF9E0000 409D0008
PATTERN: FF9E0000 48000008
If you harm an enemy, it's instantly dead. The same applies to you though. You touch acid, you get shot, or something hits you, you're instantly dead. Think of it like Devil May Cry's heaven or hell mode. Combine this to make aliens dumber, and they should be even easier.


Aliens Don't Move Or Attack
00668268 4800000C
ORIGINAL PATTERN: C1410078 FF8A0000 409D000C
PATTERN: C1410078 FF8A0000 4800000C
I checked other enemies too. They stand in place and turn and shoot at you if they can.


Many Things Are Very Bright White
000650E8 3F4044FA

000650F0 934B0010
000650F4 934B0020

PATTERN: 3F4044FA 934B0000 934B0010 934B0020
There's many dark places in this game making it hard to spot some enemies. This should help you spot them as long as they aren't standing by a bunch of things that are very white to blend into.


Aliens Spin In Circles Trying To Move
0067CDB4 60000000
0067CF14 60000000

Turrets Don't Turn To Shoot
0067E1E4 60000000
0067E28C 60000000
ORIGINAL PATTERN: 409D0008 FF80E050 D3E100A0

Aliens Don't Attack
005D93C0 48000010
ORIGINAL PATTERN: 409D0010 817F0030
PATTERN: 48000010 817F0030
This has a bad side effect of not letting the predator do melee attacks.


Always Running
005CAF08 3C00447A
005CAF0C 901F00A4
ORIGINAL PATTERN: FF80F800 409D000C EC005028
PATTERN: 3C00447A 901F00A4 EC005028
I've only tried this as a marine. Any forward movement causes you to run, and you can run forever without stopping for 2 seconds to catch your breath.


EDIT: 11/9/2012
Added a few more codes. At the moment I also noticed something made my flashlight not appear, it might just be a light size of brightness. Something made turrets not shoot, so I'll be looking into that. Another allowed me to jump higher, and that's the one I'm currently looking at.

Jump Height/Movement Speed Modifier
000A343C 3C00????
000A3440 90030100
ORIGINAL PATTERN: 4800CA51 60000000
PATTERN: 3C00???? 90030100
The value is a float, and this is a little odd. 3F80 seems to be the normal number. If you set it higher than that, you will be able to move faster but won't be able to jump. If you set it to a fraction between 0 and 1, you'll move a tiny bit slower but will be able to jump higher. These are some useful values:
3EC0 = Jump fairly high and won't damage an entire health bar.
3F00 = Jump a little less high, but won't take any falling damage.
42C8 = Can't jump, but you walk incredibly fast.

Explosive Gas Tanks Don't Explode
0026F664 48000008
ORIGINAL PATTERN: 409D0008 808B0000

Increased Brightness
0015BC48 3C00BF80
ORIGINAL PATTERN: EB810080 3C003F80

Brightness Modifier
00162FF0 3FA0????
RIGINAL PATTERN: 8122B5F8 3FA03F80
PATTERN: 8122B5F8 3FA0????
If you want the game very dark, set it to 0. If you want everything to look like the sun is shining directly on it, go with 4240 or higher.

Faster Animations
001CC498 60000000
ORIGINAL PATTERN: EC21037A C17F003C
PATTERN: EC21037A 60000000
You instantly reload, instantly heal, instantly do animation sequences, fire guns like the pistol and sniper rifle a lot faster, and probably more. This affects enemies too though. Aliens are kind of dumber and attack less, but when they do hit they are very fast.

Rapid Fire
004D5EEC 60000000 (Pulse Rifle Primary Fire, Smart Gun)
004D5FE4 60000000 (Pulse Rifle Grenades, Pistol, Sniper Rifle)
ORIGINAL PATTERN: EC00D828 D01E0108
PATTERN: EC00D828 60000000
ORIGINAL PATTERN: EC0D0028 D01E00E8
PATTERN: EC0D0028 60000000
For the pistol and sniper rifle, you'll need to melee in between clips to reload. If somebody can find unlimited ammo, that would make this much more useful. The pistol is still a killer with this though.

EDIT: 11-19-2012
Nothing Can Take Damage
003681B4 4E800020
ORIGINAL PATTERN: 4BFFFB7C F821FE01
PATTERN: 4BFFFB7C 4E800020
Why you'd want this is beyond me.


Marines & Androids Are Invincible
003B3594 60000000
ORIGINAL PATTERN: C3E90030 4BFEAA91
PATTERN: C3E90030 60000000
You won't react to anything in any kind of way. You can't be grabbed, and you can't kill them with a grab. Falling in a pit of lava does nothing to you. No amount of bullets, acid, explosions, or anything will do anything to you. You can combine this with the code for killing anything with 1 hit to easily take down any other enemies. Aliens never fight other aliens, and predators never fight other predators, but playing a marine has just those stupid androids everywhere making this code a little bit of a problem unless you use CodeUnique to toggle this on or off when needed to kill them.

Predators Are Invincible
003C6B74 60000000
ORIGINAL PATTERN: 7BE40020 4BFD74B1
PATTERN: 7BE40020 60000000
You won't react to anything in any kind of way. You can't be grabbed, and you can't kill them with a grab. Falling in a pit of lava does nothing to you. No amount of bullets, acid, explosions, or anything will do anything to you. You can combine this with the code for killing anything with 1 hit to easily take down any other enemies.

Aliens Are Invincible
003A4E8C 60000000
ORIGINAL PATTERN: 7FBFEB78 4BFF9199
PATTERN: 7FBFEB78 60000000
You won't react to anything in any kind of way. You can't be grabbed, and you can't kill them with a grab. Falling in a pit of lava does nothing to you. No amount of bullets, acid, explosions, or anything will do anything to you. You can combine this with the code for killing anything with 1 hit to easily take down any other enemies.


Enemies Never Turn To Aim
0067DC84 4E800020
ORIGINAL PATTERN: 4BFFFCA4 C002BB04
PATTERN: 4BFFFCA4 60000000
It's useful in the way that all you need to do is never stand directly in the line of fire for enemies with weapons. If you can do that, you can easily get behind them and grab them or kill them any other way. It makes it much easier to avoid being hit by bullets.


If for any reason somebody needs these, these are also things that cause invincibility to things:
003B3D08 60000000
003C6920 60000000
003CD774 60000000
003D1568 60000000
003D3374 60000000
I didn't check what they affected, but I see no reason to make something like a facehugger invincible since they are always your enemy. Who wants to run from them forever?
