Dead Rising 2: Case Zero infects XBLA August 31

Better refill your Zombrex prescription: Capcom is letting Dead Rising 2: Case Zero out of quarantine and into Xbox Live Arcade on August 31 — the original release date of the full Dead Rising 2 game (that's now dated for September 28). Capcom has also released a new trailer for Dead Rising 2, which you'll find after the break.

Case Zero, a standalone experience, serves as a prologue to Dead Rising 2. Chuck Greene fights to escape the town of Still Creek and obtain the Zombrex he needs to keep his daughter Katey from coming down with a case of finding human flesh yummy.

The prologue won't take a bite out of your budget: Capcom is pricing the XBLA-exclusive Case Zero at 400 Microsoft Points ($5).
