At long last, Warhammer 40,000: Space Marine's co-operative mode, "Exterminatus," is now available to download on PlayStation 3 and Steam, with the Xbox 360's availability coming soon. All you have to do is boot up Space Marine and accept the auto-update.
As we've mentioned countless times now, "Exterminatus" provides four-player co-operative play against endless waves of Orks, and spans two levels. All of your loadouts and perks from multiplayer will be available to use in "Exterminatus," and experience earned in the add-on will also transfer to your multiplayer rank, giving you a nice little two-fer.
