The second map pack for Call of Duty: World at War will be available this June, and it’s dragging a horde of Japanese zombies along with it. As with the first map pack, this one does more than merely add a new zombie level. Three new multiplayer maps will be included; Banzai, Corrosion and Sub Pens.  These maps revolve around a river bridge, a train yard and a CQC environment respectively. The new zombie map is called ‘Shi No Numa’, meaning Zombie Swamp. You’ll once again have access to traps and perks to keep the zombies at bay, plus the new Wunderwaffe DG-2. As a final touch, there are ten achievements/trophies to unlock for your whoring pleasure, so have fun with that.
