Aliens: Colonial Marines Is Gunning For A Spring 2012 Release.

But that's changed this afternoon, as SEGA's finally decided to bring the title out of the darkness and confirm a "Spring 2012" launch window for the game.

“To Gearbox Software and its peers throughout the industry, Aliens is one of the most influential science fiction properties of all time,” said Gearbox boss Randy Pitchford.

“Aliens: Colonial Marines, designed as an interactive successor to the landmark films from Twentieth Century Fox, is a dream project about which our studio is deeply committed and passionate.”

Expect a massive blow-out on the title at E3. In the mean-time, enjoy the teaser trailer after the jump.
