Reinforcements are scheduled to arrive, as Activision confirmed plans today to deliver Call of Duty: World at War Map Pack 3 in August.

Map Pack 3 will feature three multiplayer maps (“Battery,” “Revolution,” and “Breach”), co-developed with partner Certain Affinity, and one new Zombie map (“Der Riese”), for the Xbox 360 and PS3.

Call of Duty: World at War Map Pack 3 follows the enormous success of its first two predecessors, which to date have sold more than four million copies on both Xbox live and the PlayStation Network.
