We previously posted information on the recently leaked “Retaliation” map pack. We mentioned there was a rumored map pack titled “Infected.” This was rumored to come complete with all four original Zombie maps from World At War, the fifth installment in the Call of Duty franchise.

This rumor wasn’t far off. It’s official; Call of Duty Black Ops: Rezurrection DLC will be available August 23, 2011 for Xbox LIVE. The map pack will come complete with remastered versions of Nacht der Untoten, Verruckt, Shi No Numa, Der Riese, and an all new zombie map called Moon. Maybe Moon will explain all of the moon rocks in previous zombie maps.

The pack will also come with a Moon theme for the Xbox LIVE dashboard. All of this will, again, be released August 23, 2011 at the price of 1200 Microsoft Points. Expect the pack on PC and PlayStation 3 in September.
