While days, weekends and marriages may soon be nullified by the release of Call of Duty: Modern Warfare 2, Activision's current zombie Nazi-shooting game Call of Duty World at War continues its ascent with the release of Map Pack 3 on Xbox 360 and PlayStation 3.

Featuring three new multiplayer maps: "Battery" based on El Fraile Island in the Philippines, "Revolution" in Russia and "Breach" in Berlin, players will also receive a new zombie map called "Der Riese" (Zombie Factory).

To make sure players get the message, Activision delivered a new trailer that shows off several other features that the Map Pack will carry from a Pack-A-Punch Machine that upgrades weapons with the touch of a button, a Bowie Knife to teleporter machines, fans are going to be hard-pressed to not buy the new DLC.

Call of Duty: World at War Map Pack 3 is available for Xbox 360 for 800 Microsoft Points or $9.99 on PlayStation Network.
