Japan gets the sequel on September 2 followed by Europe on September 3. All three versions of the game--PC, PlayStation 3 and Xbox 360--are due simultaneously.
In addition, the Xbox 360 will get an "downloadable prologue" dubbed "Dead Rising 2: CASE ZERO" that's due to arrive "shortly before the title releases in August." The "exclusive Game Add-on" is said to "allow Xbox 360 gamers to get their first glimpse into the Dead Rising 2 story with exclusive content that will not be featured in the full game."
Explained Capcom: "CASE ZERO will introduce main protagonist and former motocross champion Chuck Greene and provide a link between the original game and the events that await players in the gambling paradise of Fortune City."
