Game is only 200 MSP on the "Sales & Specials" app
Anybody might be interested.
If you have the "Sales & Specials" app, play the scratch game, and Dead Rising: Case Zero will be offered for only 200 MSP (available as of this writing, Sept. 1, 2012).
Wanted to get it, but I'm from Asia and it seems the game is region locked. Real shame.
