GameTrailers got the scoop this week that after beating the campaign mode of CALL OF DUTY: WORLD AT WAR, the latest in the World War II FPS series out November 11th, you will unlock a multiplayer co-op mode in which up to four players will have to defend a derelict farm house from wave after wave of zombie horde.

Not only will players have to take out undead Nazis, but they’ll have to work together to rebuild the house’s defenses as the brain cravers rip the walls apart.  There is also no end to the mode other than the players’ ability to outlast the zombies, who will get harder and harder to stave off with every wave.

Looks like I’ve now got a reason to buy CALL OF DUTY: WORLD AT WAR.  That sounds fun as hell.
