Call of Duty: World at War Map Pack 1 hits the PC, Playstation 3 and Xbox 360 in March with four new maps, including one for the game's cooperative Nazi Zombie mode.

Nightlife is a multiplayer map in war-ravaged Berlin.

Knee Deep will have you attacking fortified Japanese positions in a jungle setting.

Station takes place in a bombed-out underground subway station.

Finally, Verrückt (Zombie Asylum) expands the zombie-killing co-op mode with more weapons, new Perks-a-Cola machines, electroshock defenses and endless, attacking legions of undead.

No word on the price for the pack, but I do like that they're not just adding new settings, but tweaking the zombie mode.
