Dead Rising 2 will include actions that will help your character Chuck Greene level without killing anything.
Speaking with Kotaku, Keiji Inafune said that there will be specific “things” that will help, but he refused to mention what it may entail.

Nothing too earth shattering, but still – it’s in Vegas, there’s zombies, and you get to use a chainsaw.
