Relic and THQ have circled the wagons as far as WH40k: Space Marine co-op news is concerned. While we may not have any new information on the cooperative front, we do have a nice, shiny developer diary for your viewing pleasure. It clearly focuses on the single player experience, which is looking rather boss.
Space Marine will hit store shelves on September 6th for the Xbox 360, PlayStation 3, and PC. We know it will support some form of co-op, and details will be coming soon.
