When you're the last man standing, fear is always your primary enemy.

Sega and Gearbox Software will deliver Aliens: Colonial Marines on February 12 and although it's currently flying under the radar, a new trailer is starting to get some attention.

It's the multiplayer video that shows off the new Survivor Mode, where four Marines have to withstand a constant barrage of aliens until only one human is left alive…and likely running for his life. The trailer lets us see some gameplay along with several really cool xenomorph designs, and we're hoping the end result is something well worth playing. We haven't had a really solid Alien-based title in a while; Aliens vs. Predator was all right but definitely short of expectations.
