Fire up Warhammer 40,000: Space Marine right now, and you can download the Exterminatus DLC for the game, which adds two co-op scenarios for up to 4-players playing as one of the various classes, with your customised space marine. Blasting Orks is the order of the day, as the Horde band together in vast numbers against your space marine unit.

You'll be able to pick from Tactical, Assault and Devastator classes, each with their own strengths, as you take on the Ork hordes with bolters, chainswords and jump packs at the ready. 'Assault on Hab Center Andreas' and 'Escape From Kalkys Facility' are the two co-op scenarios, offering leaderboard support and the opportunity to boost your multiplayer rank.

So, if you're up for a score attack and the chance to plough through wave after wave of Orks, then you can download the Exterminatus update by simply starting up Space Marine now. Check out the trailer for the co-op DLC below.
