Activision have announced new content in the form of a downloadable map pack for Call of Duty: World at War.

The map pack contains three new multiplayer levels, as well as an additional level for the surprisingly successful Co-Op Nazi Zombies mode.

In "Nightfire," players take to the streets of a war-ravaged Berlin with only the flames of the burning city to expose the enemy. "Station" offers a bombed out underground train station littered with hidden passageways and destroyed subway cars, and "Knee Deep" takes place on the island of Peleliu in a once tranquil village turned chaotic Japanese command center.

Verrückt (Zombie Asylum) is a terrifying Zombie asylum featuring more weapons, perks via the addition of Perks-a-Cola machines, electroshock defenses and the endless zombie horde.

This first map pack will be available in March for the PS3, Xbox 360 and PC versions of Call of Duty: World at War.
