Activision and Treyarch have announced that the third map pack for Call of Duty: World at War will be available for the Xbox 360 and PS3 this August.

Map Pack 3 will include three multiplayer maps, Battery, Revolution and Breach (which have been co-developed with Certain Affinity), and one new Zombie map called Der Riese.

Here’s the lowdown on the new maps straight from the Call of Duty website:

“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.”

Battery

“An armored island surrounded by anti-ship mines and shore to ship cannons, Battery places soldiers on a mid-sized map based on Fort Drum (El Fraile Island) in the Philippines. Expect plenty of areas to hide and heavy close quarters combat!”

Breach

“Overwhelm the enemy in Breach, set in Berlin’s overcast and crowded city streets surrounding the historic Brandenburg Gate. Only the fittest will survive in this fast-paced, dense battlefield!”

Revolution

“Revolution pits soldiers against each other in Russia’s cold city streets and large factory environment. Keep your fingers warm, your gun loaded, and your head low through this sniper-friendly territory!”

Der Riese

“The undead horde approaches! Fight for your life in Der Riese (Zombie Factory), an all-new Zombie map set in a secret Nazi research facility featuring the Pack A Punch Machine, a device capable of upgrading weapons at the touch of a button. Use the teleporters to escape the vicious Hell Hounds and pray that the Wunderwaffe will appear before it’s too late. This map includes 10 new Achievements/Trophies.”

The first two map packs have proved to be very popular to date, selling a combined total of over four million copies on Xbox Live and the PlayStation Network. Call of Duty: World at War has itself sold more than 11 million copies across all platforms according to data from the NPD Group, Chart Track and GfK.
