Sega and Gearbox have a new trailer up detailing the Marine and Alien multiplayer classes in Aliens Colonial Marines
. As you'd expect the Marines have all of the fan-favorite equipment from the movie, including the flamethrower, smartgun and shotgun. What's more interesting is the new class system for the Aliens, which lets you play as the kamikaze Boiler alien, the acid-spewing Xeno-spitter, or the massive, unstoppable Crusher alien. ACM's multiplayer is looking more and more like Left 4 Dead, and if Gearbox can successfully replicate that game's pitch-perfect balance, we're in for one hell of an Aliens-themed team versus mode.
