As if all of the craziness we already knew about in Dead Rising 2: Off the Record wasn't enough, Capcom has even more to reveal at PAX this weekend, apparently. The company is showing off the game's Sandbox mode, which will let players run around Fortune City and cause as much mayhem as wanted "without having to worry about the clock."

The mode also offers a series of challenges in each of the game's environments (ranging from simple collection to killing zombies or driving around in vehicles) that will offer up cash as a reward. We've got a couple of Joystiq folks on the show floor at PAX, so stay tuned for a hands-on report about the mode itself.
