SEGA announces that Aliens: Colonial Marines is now available worldwide, offering a new first-person shooter set in the Aliens sci-fi setting for Windows, Xbox 360, and PlayStation 3, with a WiiU edition coming at some future date. Here's the official launch trailer for the game, and here's word:

SEGA® of America, Inc., SEGA® Europe Ltd., Gearbox Software and Twentieth Century Fox Consumer Products® today announced that its highly buzzed-about blockbuster Aliens™: Colonial Marines video game is now available on store shelves across the globe for PlayStation®3 computer entertainment system, Xbox 360® video game and entertainment system from Microsoft and Windows® PC. A release date for the announced Wii U™ version will be revealed at a later time.

Pitting players against the universe’s deadliest killing machine, the Xenomorph, Aliens: Colonial Marines is the official video game continuation to one of Sci-Fi’s most renowned movie franchises. As the authentic addition to the ALIENS canon, the game’s stunning visuals and adrenaline pumping action will deliver a breathtakingly immersive four-player drop-in drop-out cooperative campaign and four expansive competitive multiplayer modes – Escape, Team Deathmath, Survivor and Extermination.

The critical reception for the game so far has been pretty negative, and Eurogamer notes a this tweet and this one from sleuth superannuation pointing to this post from last year that he disregarded at the time. This includes a comment from someone claiming to be an ex-developer on the project saying at the time development had "been a total train wreck," and that Gearbox was only developing the multiplayer portion of a game primarily designed by TimeGate Studios.
