Dead Rising 2: Case Zero, the prequel for the upcoming game Dead Rising 2, has been announced to be a measly 400 Microsoft Points ( or $5 in human money) and to be released on August 31st on the XBL game marketplace. Be sure to look for it when it hits because at such a low price Capcom isn't going much for profit but, more just to get this prequel of a sequel in your hands.
