Activision and developer Treyarch have confirmed plans for Call of Duty: World at War Map Pack 2. Set for release in June, Call of Duty: World at War Map Pack 2 will feature three multiplayer maps and one new Zombie map, and appear on the Xbox 360 and the PlayStation 3.

Online, players will compete in “Banzai,” and fight for control of a tall, river bridge, deep within enemy territory; face down foes in a shattered Russian train yard in “Corrosion”; and struggle to control a bombed-out submarine base in the close-quarter map, “Sub Pens.”

In “Shi No Numa” (Zombie Swamp), Imperial Zombies rise from misty swamps in an all new co-op experience, with a level that features a mix of traps, flaming Hell Hounds, Perk machines and the deadly, new Wunderwaffe DG-2, as well as 10 new Xbox 360 Achievements/PS3 Trophies that can be earned along the way.
