Gearbox Software's hotly anticipated shooter Aliens: Colonial Marines will be out for PS3, Xbox 360 and PC in the first quarter of 2009, SEGA has confirmed.

The news puts paid to concerns over the development of the game following perceived lower than expected sales of Brothers in Arms: Hell's Highway.

Although SEGA was unable to clarify exactly what months Q1 2009 include when contacted by VideoGamer.com, it is expected to run from April to the end of June, the first three months of the Japanese company's financial year.

In November last year Gearbox president Randy Pitchford issued a statement to press confirming Aliens had not been canned following rumours that SEGA had cut the funding on the project.

The Aliens: Colonial Marines confirmation comes in an updated release schedule sent to media today by SEGA. It details a February release for House of the Dead: Overkill and spring release for The Conduit on Nintendo Wii, as well as a Q1 2009 release for Obsidian RPG Alpha Protocol.
