ATTENTION PLAYERS: Don't forget to fix your AI
To anyone unaware (which is likely many, especially with the sale resurgence) -- the enemy AI has a behavior bug that makes them mindless suicide runners, instead of acting like Xenomorphs.
Pisspoor coding is to blame, and the fix is simple:

Step 1: Open (My Documents\My Games\Aliens Colonial Marines\PecanGame\Config\PecanEngine.ini)
Step 2: Find ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether -> PecanGame.PecanSeqAct_AttachPawnToTeather
Step 3: Change "AttachPawnToTeather" to "AttachPawnToTether"

Save the file, and set it to read-only to be safe. Voila, you have fixed the AI, and the game won't suck anymore.
If you are playing co-op, all players must have done this -- or the AI will default back to being broken for everybody.

I hope this helps players who may be getting turned off by the game.
The issue made major outlets in 2018, and has not yet been patched:

Citation is readily available if anybody thinks this prospect is dubious:

They have not, sadly -- at least not on Steam. Players must do it manually.
Was checking my files from 2016 and this parameters was named as 'AttachPawnToTeather'. But I find there was two parameter instances of ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether -> PecanGame.PecanSeqAct_AttachPawnToTeather
Edited again and going test. Maybe I've forgot in the past to make the file read-only in the attributes. Thanks for sharing back.

P.S. Hilarious how this game is bad in all forms. I can't jump scare playing alone when I was attempting to play in nightmare difficult marine's campaign in AvP 2010. That game btw is 8.0 compared to this 4.0.

Yeah, it's specifically the 'Teather" that is the typo.
When I changed mine, I searched that out on its own in the .ini -- it may very well have multiple instances, but 'read-only' issue is the most likely candidate.

Someday soon, I hope to get a solid 4-man co-op campaign going with players who respect the story experience of a co-op campaign, and can make the playthrough top tier.
Pardon for intruding but you got bulldozer PC why care about this game? I am only back because can't afford a better setup therefore can play just boring stuff that still run win.7....miss Destiny2 alreadyo.0

I wish that were so... LOL.
My GFX card is ancient and a real bottleneck on what I can run decently/at all.
Even things I can run fine will sometimes be crippled by a missing shader, or other -- and ATI/AMD surely won't be updating the drivers after they literally tried to burn out the line moving to "Crimson".

They built these cards too well, and their attempted digital homicide is still not forgotten.

Any clue where this file is on a Deck?

Should be something like:
/home/deck/.local/share/Steam/steamapps/compatdata/49540/pfx/drive_c/users/steamuser/Documents/My Games/Aliens Colonial Marines/PecanGame/Config/PecanEngine.ini

From a terminal, use this command to find it;
find ~/ -name PecanEngine.ini

Its development was a ♥♥♥♥♥♥♥♥ and you can thank Gearbox CEO Randy Pitchford for it. Go watch “The Tragedy of Aliens: Colonial Marines” by GVMERS on YouTube for a chuckle.

Thanks for your suggestion, but it's a fallacy.
I had to manually update the files on this most recent install, made well within the last 3 months.
The article cited (one of several available) was also written years after the game's release -- so claiming it was patched in any timeframe close to that is objective misinformation from you.
Try speaking some truth for once, weird internet stranger without a clue.

A detailed patchlog says 'no, it is not'.
