Dead Rising: Watchtower takes place during a large-scale zombie outbreak. When a mandatory government vaccine fails to stop the infection from spreading, the four leads must evade infection while also pursuing the root of the epidemic, with all signs pointing to a government conspiracy. Politics, public paranoia, and media coverage play an important role in the story's narrative.

Dead Rising: Watchtower is written and co-produced by Tim Carter, who produced Mortal Kombat: Legacy and wrote Sleeping Dogs.

The Dead Rising movie will debut on Crackle, Sony's streaming video service. Crackle apps are available for PlayStation and Xbox platforms, as well as PC and mobile devices.
