Fear Factor is the ultimate adrenaline rush, a true test of stamina and guile for those willing to put their body and soul on the line for cold hard cash. It's not a show for the faint-hearted; participants must confront their most primal fears, try to remain calm and tap into their inner strength to perform some of the most daring and stomach churning challenges ever. Three men and three women compete against each other in four stunts designed to test them both physically and mentally to their absolute limits. The prize is $50,000 (AUD).
