Bridging the gap between the original Dead Rising and its sequel, the 'Case Zero' prologue will be released for Xbox 360 ahead of the full game to show how the adventures of Chuck Greene and his daughter began.

Dead Rising 2 is slated to hit PC, Xbox 360 and PlayStation 3 simultaneously on August 31 in North America, coming to Europe on September 3. If you're an awful person, you'll be delighted to hear that Playboy pictures will be featured throughout the game.
