Ok, yes: the Marines in Gearbox's officially sanctioned Aliens shooter have some cool guns. But, honestly, if you're going to pick up this game, do you really want to play as another sci-fi soldier? No, you're not. You're going to want to impale humans on your deadly tail, slash them to bits and spit acid as a Xeno. There's a few different classes of Xeno on display in the trailer, including a big, hulking varietal that wasn't ever in the Aliens movies. Good luck trying to find anyone who'll play as Marines.
