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 behavior 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!
