Because of Treyarch and Activision selling more than one million copies of Call of Duty: World at War Map Pack 1 during its first week of release, they will be releasing another map pack, 2, come June 2009.
The Call of Duty: World at War Map Pack 2 will introduce three new multiplayer maps: “Banzai,” a jungle environment riddled with caves; “Corrosion,” a Russian train yard; and “Sub Pens,” a rain-drenched submarine base.
That’s all well and good, but now for the good stuff: a new Nazi Zombie map! “Shi No Numa,” home to this guy, promises new Perk machines, a new weapon, new achievements / trophies and flaming Hell hounds. It also promises to keep our repository of nightmare material well-stocked.
