Are you attempting to play Die Rise offline? If so, Activison/Treyarch are aware of the problem and are working on a fix.
We are aware that Die Rise, the Zombies map that is part of the Call of Duty: Black Ops II: Revolution DLC Map Pack, is currently unable to be played in offline local mode. We will be fixing this issue in a future update, so please stay tuned for more information on this matter being resolved over the next couple of weeks. In the meantime, in order to play Die Rise in any mode, your Xbox 360 must be connected to the internet. We appreciate your patience.
