Experience Aliens: Colonial Marines how it should have been when it first released. This heavily balanced and thoroughly play-tested mod is built for exciting, suspenseful and most importantly, fun gameplay.

Xenomorphs have seen the most improvements, with fixes to their behaviour and core mechanics to make them truly terrifying foes, dramatically shifting the tone of the entire campaign.

This state of the bad-ass art modification for Aliens: Colonial Marines reworks, reprograms and rebalances xenomorph AI, human AI, weapon mechanics, ballistics, animations, shaders, particles, decals, lighting, and engine features to get the best out of the game possible. This is truly the ultimate Aliens gaming experience!

If you would like to see the full list of changes included in the latest version of the mod, you can check out the changelog by clicking here.

This project is a work in progress and will be expanded and improved over time to try and refine the game even further to an enjoyable experience. We're open to suggestions and feedback to help shape the future iterations of the mod!

Switch the double barrel shotgun back to buckshot because no one puts birdshot on a sawed off shotgun

Anyone happen to know what spec you should have to run the mod?

Hey Temp? I'm having a hard time gettin' the ol mod to run right. Getting it to launch took removing d3d9.dll from the binaries folder at the suggestion of a random forum dweller after many failed attempts, now the game crashes hard at certain points, most notably during mission 2 of Stasis after I call the elevator. Thoughts?

One thing to look at is to set all the sliders for the graphics at about 90%. This has to be done at each launch of the game, you will notice how the sliders are out of their bounds. Hope this helps.

Turns out the biggest bug in the game isn't just one letter long Templar, it's one letter wrong too.

I've found out ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether also has a typo on the exact same line as the AttachPawnToTeather typo. It says ClassRemapping=PecanGAme with a capital A in Game which could potentially be causing a problem as well. This exists in the DefaultEngine ini file, which is what serves as a default for the PecanEngine config in My Documents.

Just been testing it out quickly with both typo corrections in the Vanilla ACM and it looks to me like the Xeno Soldier's are definitely wall and ceiling climbing more, only tested No Hope in Hadley's so far.

This typo is in the DefaultEngine.ini, in your Steam\steamapps\common\Aliens Colonial Marines\PecanGame\Config\ directory... At least, that's where I found it.

For the first time the game got my heart pumping. While the story still sucks, you did the unthinkable. The game is FUN... Thank you. Thank you so much.
