For Treyarch’s upcoming Call Of Duty: World At War, Going back to World War II after the wild success of Modern Warfare might have seemed like a step backwards into safe and familiar territory. As if to appease the Nazi-weary masses, Treyarch revealed this week that WAW will feature an unlockable zombie apocalypse co-op mode.



Available after completing the single player campaign, the co-op mode pits players against wave after wave of Nazi zombies, and will include movable barriers and weapons caches.  Check out GTTV for more details.
