"'Wipeout'- if you build it..they will fall," says host John Henson. This week "Wipeout" unleashes a new obstacle, named by viewers the Wheel of Misfortune, which is sure to leave players down on their luck. Contestants, vying for the $50,000 grand prize include two high school students, Chaz Hands and Tapping Tony, who compete against a Competitive Dad and a Dinner Detective. Players also take on the stunt that sends them flying head over heels -- as Total Carnage makes its triumphant return along with the Wipeout Playset -- before the final three players face off on the all-new Summer Wipeout Zone, featuring the seven story Towering Flume of Doom.
