Grab fireworks from Astonishing Illusions right next to the ride. Clear some of the Metal Barricades that are surrounding the ride. Toss out the Firecrackers to draw the 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 and crush the zombies.
