PlayStation 3 and PC owners of Call of Duty: Black Ops II will be getting the Uprising downloadable content starting on May 16. The DLC will run $14.99, includes four new maps, and the new Mob of the Dead addition to the zombies experience.
We reviewed the Uprising content, and as it turns out all the new additions are really good. Chris Carter loved the Mob of the Dead stuff, and found that "Treyarch had a lot of fun" designing the four new maps.
