Earlier this summer, Gearbox Software started showing off Aliens: Colonial Marines. We've seen short trailers and screenshots in the past, but Gearbox has just released an 11 minute gameplay walkthrough video that gives us a better idea of what to expect from the upcoming game.

Created as a canonical sequel to Aliens, the game is a squad-based FPS that is being developed for the PC, Xbox 360, and PlayStation 3. For those looking for more Alien gaming in the near future, Gearbox and WayForward have worked together on Aliens: Infestation, which will be available for the Nintendo DS on October 11th.

“SEGA Europe Ltd. and SEGA of America, Inc., have announced that the highly anticipated first-person shooter Aliens: Colonial Marines will be launching in spring 2012 on PC, PlayStation 3 computer entertainment system and the Xbox 360 video game and entertainment system from Microsoft.

In partnership with Twentieth Century Fox Consumer Products and developed by critically acclaimed studio Gearbox Software, Aliens: Colonial Marines will bring new levels of bone-chilling suspense and adrenaline-filled action to the renowned franchise. The game pits players against the universe’s ultimate alien killing machines, the Xenomorphs, in claustrophobic environments guaranteed to produce blood-curdling thrills that the movie is renowned for.

Aliens: Colonial Marines begins with an ostensibly abandoned ship, the U.S.S. Sulaco, recovered in orbit around LV-426. Players lead a group of highly trained United States Colonial Marines as they board the deserted craft to uncover the fate of the crew. They will have to fight to survive unspeakable horrors and their own anxieties as they chase down the truth behind a galaxy-spanning deception that places humanity at the mercy of the most murderous and deadly species in the universe. Aliens: Colonial Marines features authentic environments, such as the surface of LV-426 and Hadley’s Hope, weapons inspired by the film series and is designed to provide an exhilarating and engaging new chapter in the Aliens universe.”
