Activision have announced this morning that the Call of Duty Map Pack 3 DLC is now available for Xbox 360 and PlayStation 3:

Call of Duty: World at War Map Pack 3 includes three new multiplayer maps and one Zombie map:

* Battery: An armoured 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. Players will have plenty of areas to hide and a steady flow of close quarters combat!

* Revolution: “Revolution” pits soldiers against each other in a large factory set in Russia's cold city streets. Keep your trigger finger primed, your gun loaded, and your head low through this sniper-friendly territory!

* Breach: Overwhelm the enemy in “Breach,” set in Berlin's crowded city streets surrounding the historic Brandenburg Gate. Only the finest soldiers will survive in this fast-paced, dense battlefield!

* Der Riese (Zombie Factory): The undead horde approaches! Fight for your life in “Der Riese” (translated: “The Giant”), 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 powerful Wunderwaffe DG-2 will appear before it's too late. This map includes 10 new Xbox 360 Achievements/PS3 Trophies.

It'll set you back 800 MS points on the Xbox and $15.95 on the PS3.
