3rd Map on the way!

Fight for ocean territory in "Battery," an armored island surrounded by anti-ship mines and shore to ship cannons. Watch out for sniper fire as you defend Russia's most coveted resource in "Revolution," and keep a sharp eye out through the dense, overcast city streets in "Breach," set at Berlin's historic Brandenburg Gate. Zombies return in all their undead glory with "Der Riese" (Zombie Factory), a Nazi research facility featuring the weapon upgrading Pack-A-Punch Machine. Use the teleporters to escape in an instant and fight to the death in pursuit of the map's 10 new Achievements/Trophies.
