Space Marine Exterminatus Cooperative Mode Announced
Coming VERY late in the game, Relic announced that a coop mode will drop one month after release of their new Space Marine video game. It's going to be in the same vein as Gears of War's Horde mode or Halo's Firefight. It'll be called Exterminatus, it will include two maps, and be playable with up to four players online. You'll fight increasingly difficult waves of enemies until Khorne himself comes down from his Throne and tells you to quit making such a mess.
