Here’s a new Aliens: Colonial Marines trailer, focusing on the game's Survivor multiplayer mode. In Survivor mode four marines go up against waves of Aliens in a confined map, securing doors and stocking up on weaponry. It looks like a twist on Horde mode, but with Xenomorphs. All of which can’t be a bad thing. Wait, did that alien just pull itself apart and explode? Watch the trailer below. Aliens: Colonial Marines is out on February 12th, worldwide. http://www.viddler.com/v/40a921fc Source - xbox360ach
