Looking to expand your Call of Duty experience? Activision and Treyarch, announced plans today to release Call of Duty: World at War Map Pack 1 for the Xbox 360.

Due out in March, Call of Duty: World at War Map Pack 1 will take fans to the streets of a war-ravaged Berlin in “Nightfire,” deep into deadly jungles to attack fortified Japanese positions in “Knee Deep” and through a bombed out underground subway system in “Station.”

The Call of Duty®: World at War Map Pack 1will also expand upon the fan-favorite four-player co-op Nazi Zombie bonus mode with “Verrückt” (Zombie Asylum) – a fourth map that features more weapons, new Perks-a-Cola machines, electroshock defenses and endless, attacking legions of undead.
