Rumor: Call of Duty: Black Ops 2 'Uprising' DLC coming April 16

Call of Duty: Black Ops 2 seems to have spilled its next downloadable content pack, with yet another promotional poster that names some maps and dates. This one is called the "Uprising" pack, and is said to be coming on April 16 to Xbox 360.

The promotional piece on MadAssGamers (via Videogamer) shows four maps titled Vertigo, Encore, Magma, and Studio. It also shows a zombie map, Mob of the Dead, which the blog speculates will take place on Alcatraz due to a telltale sign.

We have some reason to be skeptical of this news, especially given its proximity to National Liars Day, but it's not as if this hasn't happened before. Shacknews has contacted Activision and will update as more information becomes available.
