Whoa, Dead Rising was just released about two weeks ago and there is Free content available already?
I'm totally stoked, usually when content comes out it's either A) absurdly overpriced (horse armor, anyone?) or if it's free…it's usually a really cheap after thought tacked on by the developer after they've realized people probably won't pay for it.
Anyway, the content on the Marketplace for Dead Rising is new and totally free.
It includes the following costumes:
* Miami Nights Key
* Casual Key
* Weekender Key
* Round Shades Key
* Burgundy Wine Key
* Grandpa Key
* Pink Paparazzi Key
* Man in Black Key
