The Call of Duty: Black Ops 2 Uprising DLC was revealed to be releasing in April. A picture of the promo art has surfaced on the internet taken by a dedicated gamer. You can check it out for yourself here, courtesy of mp1st.
You can make out what the levels might be about from the art. The Magma map has a city build near a volcano so maybe we can expect something cool like a volcanic eruption. The Encore map takes place what looks to be like a music gig, which would be fitting to the name. The Mob of The Dead map clearly has some fun zombie action taking place near what seems to be a prison. The picture for the Vertigo map has a helipad and skyscrapers and as the name suggests, it might have to do with some cool aerial action. Finally, the Studio map seems to take place at the shooting of a movie.
We will keep you updated as more news is revealed.
