We may be getting the next Black Ops II DLC on April 16th with "Uprising."
According to reportedly leaked Black Ops II promotional materials, the next DLC will be titled "Uprising" with a plethora of new maps.
The Black Ops II "Uprising" promo image below reveals Magma, Encore, Vertigo, and Studio maps, as well as one for zombie mode with Mob of the Dead.
mp1st.com reports that Black Ops II "Uprising" might have an April 16th release most likely for the XBox 360 first, much the same way "Revolution" was available exclusively on that system before becoming available on the PS3.
Earlier, "Uprising" was discovered as part of developer's code for Black Ops II as well.
Looking closely at the Mob of the Dead image seems to reveal that the level might take place in a prison - Alcatraz.
Call of Duty: Black Ops II was co-written by David Goyer, known for the Batman films and the Man of Steel.
