The game isn't considered canon, as most of the main cast is drastically changed to keep it interesting. Chuck Greene appears as one of the psychopaths, his daughter Katey does not make an appearance, and Stacey and Sullivan have new allegiances. The gameplay mechanics and goals are the same as Dead Rising 2 : Frank must follow and complete cases within a certain time frame or the truth will vanish. He can escort survivors back to safety, and needs Zombrex to keep from becoming a zombie. This time, Frank needs Zombrex, and does not have to return to the Safe House to inject it. Off the Record returns photography to Dead Rising , and adds a new section of Fortune City, Uranus Zone. Additional combo weapons can be made, Frank's hand-to-hand fighting style differs from Chuck's, and Chuck Greene is the second player in co-op games.
The game features a sandbox mode, where players can roam Fortune City with no time restrictions and no need for Zombrex. Levels, skills, and money gained in the sandbox mode carry over to the story mode, just like the money Chuck made in Dead Rising 2 . There are also challenges scattered throughout the map in sandbox mode.
