Building on the success of Map Pack 1 and Map Pack 2, we’ve decided to continue support for CoDWaW and announce the upcoming release of Map Pack 3. Today, we’re happy to bring you the first details.

Call of Duty: World at War Map Pack 3 further expands the awesome COD multiplayer experience with four brand new maps.

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.

Map Pack 3 is slated for release this August. Keep an eye out here at CoDWaW.com for more information regarding Map Pack 3, and follow @JD_2020 on Twitter for the latest news as it breaks!
