Despite an erroneous report circulating the web that suggests otherwise, Dead Rising 3 is not coming to Xbox 360.
"Reports from [Eurogamer Expo] that Dead Rising 3 will launch on Xbox 360 are false," reads a tweet sent out by Major Nelson. "It's an Xbox One exclusive - no plans for 360."
Since it was announced at E3, Dead Rising 3 has always been portrayed as an Xbox One exclusive. It's in development at Capcom Vancouver (the former Blue Castle Games), the same team responsible for Dead Rising 2 and its spin-offs, but unlike previous Dead Rising games, it's being published by Microsoft, not Capcom.
IGN's most recent hands-on with the game came at the Tokyo Game Show. The demo showed, among other things, an improved framerate over what was on display at Gamescom.
Dead Rising 3 is scheduled for release on Xbox One alongside the console itself on November 22.
