As previously rumoured, the Black Ops 2 DLC will be titled Uprising and is set for release on Xbox Live on April 16 priced at 1200 MSP (£10.28 / €14.40 / $15.00).
While publisher Activision declined to comment when we got in touch earlier this week, the game add-on will feature multiplayer maps Vertigo, Magma, Encore and Studio, plus a fresh Zombies mode called Mob of the Dead.
And fresh shots of promotional material for the DLC provide a clearer image of what we can expect, as does the following content description supposedly unearthed on the Xbox Live Marketplace Upload Registry (via Charlie Intel).
Call of Duty: Black Ops II Uprising includes four incredibly diverse Multiplayer Maps: Magma, Encore, Vertigo, and Studio: a reimagined adaptation of the fan-favorite Black Ops multiplayer map Firing Range. Uprising also introduces Mob of the Dead, Treyarch's most terrifying Zombies experience to date. Top Hollywood talent rounds out a cast of four Prohibition-era gangsters that are forced to fend off hordes of the undead while imprisoned on San Francisco's notorious Alcatraz Island. While guard towers and new weapons offer tactical advantages, survival offers an unprecedented new challenge for these four lost souls.
The latest images from Uprising promotional material suggest Encore may be set in London as Big Ben seemingly appears in the picture. Magma will also feature volcanoes and Vertigo will play home to a rooftop with a helipad. Vertigo was reportedly the name of a planned Call of Duty: Modern Warfare 2 multiplayer map that was scrapped due to its similarities with Highrise.
