An epic bug hunt featuring a unique blend of co-op play and squad-level tactics. With your friends, form a squad of four distinct IAF Marine classes. Plan your attack using an unlockable arsenal of weapons with countless loadout configurations against a wide variety of aliens. Blaze your way through an overrun, off-world colony, eradicating the alien infestation in environments ranging from the icy planet's surface, to a subterranean lava-flooded mining facility.
Ever wish all those terrifying aliens sounded more like the characters from Team Fortress 2?
A simple mod that changes all the alien's sound files to clips from different Team Fortress 2 classes. This is not only funny, but actually helps you play by making certain alien types have more easily distinguishable sounds.
Mostly the fact that you can clearly hear the Parasites as spies, and the shield bugs as Heavys.
