Back during X10, Capcom revealed Dead Rising 2: Case Zero, the stand-alone prologue exclusive to Xbox Live Arcade that will bridge the gap between the first and second game. It will introduce the sequel's protagonist, Chuck Greene, father and master of duct taping stuff, as he works to free himself and his daughter from the desert town of Still Creek -- two years after the events of the first game, but three years before the events of the sequel.

Shacknews managed to secure the details while at Captivate in Hawaii, and says Capcom promises Case Zero will have "unique content not available in the full retail release of Dead Rising 2." Sadly, there's no mention of price or release date for Case Zero, but rest assured: You still have plenty of time to stock up on Zombrex before Dead Rising 2 launches on August 31.

Editors' note: Joystiq did not attend Captivate this year. We determined the perceived environment, and associated downtime, of the event was not in accordance with our editorial policy. We expect to provide firsthand preview coverage of all Capcom titles shown at Captivate during E3 this June. For more information on our policies, click here.
