UFO Crash is a ride located in the Uranus Zone in Dead Rising 2: Off the Record.
It is possible to crush groups of zombies using the ride, making it an good option for completing the Killer Rides sandbox challenge. Grab firecrackers from Astonishing Illusions, located right next to the ride. Clear some of the metal barricades surrounding the ride. Toss out the firecrackers to attract zombies around the UFO Crash seats. Quickly head to the control panel next to the ride and activate it. The ride begins by shooting the seats up, killing several zombies. Continue to place firecrackers around the hole left by the ride, and the UFO base will drop down, crushing the zombies.
