After a Gamestop listing outed a cooperative mode in upcoming action shooter Warhammer 40,000: Space Marine last week, THQ has confirmed that co-op will indeed feature in the game. A THQ manager has explicitly outed the mode on the official forums, and confirms to ShackNews that "Warhammer 40,000: Space Marine will have co-op and we look forward to announcing more details later this month."
However, it's not as straightforward as it sounds. Apparently the cooperative features won't be ready for launch and will instead be released thirty days later as a DLC pack. It will be free download if you buy a new sealed copy, but otherwise, you'll need to pay for an online pass before you download it.
Space Marine will launch on September 9th for PS3, Xbox 360 and PC. Why not check out Brendan's recent hands-on preview while you wait?
