Call of Duty: World at War Map Pack 2 continues to expand the addictive COD multiplayer experience with four new maps.  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 return in “Shi No Numa” (Zombie Swamp) featuring Perk machines, the deadly new Wunderwaffe DG-2, new Achievements/Trophies and flaming Hell Hounds.

Deep in the jungles of Japanese controlled territory, battle to control the tall river bridge in "Banzai" a bright, medium sized jungle map featuring a waterfall, villages and hidden caves well suited for deadly snipers, surprise attacks and all out gun battles.

In "Corrosion" face down your enemy in a deteriorated Russian train yard. Sprint under, over and through the shattered pipelines and war-torn train cars in this mid sized map great for full out team combat. Keep your head on a swivel as your enemy could be above or below you!

"Sub Pens" offers a close-quarter bombed-out Japanese submarine base littered with live ammunition, breached subs and idle fighter planes. Wipe the monsoon rains from your eyes and struggle to control key choke points in this tight map designed for exciting and deadly battles.

Keep moving to survive the unending Zombie horde in "Shi No Numa", the all new addition to the four player co-op fan favorite. Imperial Zombies rise from the misty swamps and flaming Hell Hounds blaze through the jungle as players struggle to find Perk machines and the deadly new Wunderwaffe DG-2 to stay alive. This new map includes 10 new Achievements/Trophies.
