Dead Rising 2: Case Zero was released last Tuesday exclusively on Xbox Live Arcade. For 400 Microsoft Points only, you get to play the prologue of Dead Rising 2, which gives you a taste of what to expect in the final game. Moreover, you can upgrade your character up to level 5 and save it for the real thing in late September. Some will say it's just a promotional demo fro which you have to pay but for the fans, the cheap price and the content definitely makes it worth their while. Here are two videos, the first one being the introduction of this short episode while the second one shows the very first case. By the way, in case you are wondering, we edited the videos so that the - awfully long - loading screens do not appear to break the pace.
