Check your ammo because the undead are coming!

Call of Duty fans will be pleased to know that the World at War "Map Pack 3" is now available on PlayStation Network and Xbox LIVE for each console.  No word on the PC version yet; the last update was released late to PC but for free.

This DLC is priced at $9.99 or 800 Microsoft Points.  Here are the new multiplayer maps -- plus one Zombie map -- you can expect with your purchase:

§  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. 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.
