Gearbox Software has unveiled a new four-versus-four multiplayer mode in Colonial Marines, Escape. In Escape, the Marines are charged with fighting their way to a safe zone, while four distinct breeds of Xenomorphs have to stop them. Yep, it's like Left 4 Dead with Aliens ... and that kind of excites me.
You can watch the trailer above, and get a glimpse of three Xeno classes -- the Soldier, Lurker, and Spitter. They pretty much do exactly as their names imply. Marines are efficient in their classification.
