Dead Rising: Case Zero is an Xbox 360 exclusive prequel to Dead Rising 2. The product acts as a demo of sorts for Xbox users, and can be downloaded for 400 Microsoft Points.
GamerBytes have noted that Case Zero has attracted over 300 000 players within its first week of availability. It is possible that, even with Microsoft taking a 30% cut of the sales revenue, Capcom could have generated over US$1 million in revenue from the title.
With this sort of revenue benchmark being set before a full title is even launched, in the future we can probably expect to see plenty more self contained prequel/demo titles emerging for big AAA games. With a price tag attached of course. 400 MS points (±R47) for a prequel might not be a bad benchmark.
Just to be clear, Case Zero isn’t merely the first few levels of the final game – it’s a self contained chapter in the Dead Rising 2 storyline. Gamers can reach up to level five during Case Zero, experience which can be carried over into Dead Rising 2 along with cash earned.

Case Zero is set three years prior to the events of Dead Rising 2 and it develops the story that occurs between Dead Rising and Dead Rising 2. Case Zero will introduce two of the main Dead Rising 2 characters – protagonist Chuck Greene, and his daughter Katey.
Dead Rising 2 will be launching on Xbox 360, PS3 and PC towards the end of September.
