From looking at the screenshots, here is what we think the plot of Dead Rising 2 is: Reality show Terror Is Reality has mortals slay zombies for cash and prizes. A virus has infected folks, turning them into zombies.
After being rounded up and quarantined, these zombies are turned into fodder for this reality show. Things go horribly, and the zombie hoard penetrates the arena and spreads throughout casino town Fortune City. And its up to reality show staffer and motorbike enthusiast Chuck Greene to save the day with his reality TV camera and duct tape.
Capcom's released a fresh batch of Dead Rising 2 screens. These are them. The game is being developed by Blue Castle Games for the PS3, Xbox 360 and the PC.
