In honor of Call of Duty: World at War Map Pack 3's imminent release, Treyarch has released a video that shows what it's like to play the new four maps.

The bulk of the video is understandably dedicated to "Der Riese," the new addition to the popular zombie cooperative mode. Once again those incorrigible zombies are trying to eat your brain and you've got to give them the old what-for. There's some brief footage of the three new "normal" multiplayer maps - "Battery," "Breach," and "Revolution" - at the end of the video.

Map Pack 3 will cost you 800 Microsoft Points ($10). It will arrive tomorrow, August 6th, on the PS3 and Xbox 360. Details on the new Achievements/Trophies are here
