New conflicts are on the horizon for Call of Duty: World at War! We're pleased to introduce the contents of our first Downloadable Content (DLC) Map Pack for World at War, which includes three new Multiplayer levels, as well as an additional level for the ever-popular bonus Co-Op mode, Nazi Zombies!
Nightfire 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 "Station" offers a bombed out underground train station littered with hidden passageways and destroyed subway cars.
Knee Deep "Knee Deep" takes place on the island of Peleliu in a once tranquil village turned chaotic Japanese command center.
Verrückt (Zombie Asylum) The fan favorite 4-player co-op Nazi Zombies Bonus Mode returns with "Verrückt," a terrifying Zombie asylum featuring more weapons, perks via the addition of Perks-a-Cola machines, electroshock defenses and the endless zombie horde.
The team has been very quiet regarding details of our DLC until now, and we're so excited to let this content loose. DLC Map Pack #1 is due out in March of '09 for the Xbox 360, Playstation 3, and PC platforms.

Call of Duty: World at War Map Pack 2 expands the addictive CoD multiplayer experience with three new multiplayer maps and one new co-op/Zombie map. Battle to control the river bridge in “Banzai” - a bright jungle map featuring a waterfall and hidden caves. In “Corrosion” face down your enemy in a shattered train yard, and in “Sub Pens” wipe the monsoon rain from your eyes as you struggle over a bombed-out submarine base. The Zombies make a return in “Shi No Numa” (Zombie Swamp) featuring Perk machines, the deadly new Wunderwaffe DG-2, new Achievements / Trophies… and flaming Hell Hounds!
