Watch The Challenge Season 18 Online

Twenty-eight excited Challenge competitors arrive in exotic Thailand and learn that they will be competing in a brand new Challenge -- The Ruins, where the players will be broken up into two teams: the Champions and the Challengers, while competing for their share of $300,000 to be banked in their own individual bank accounts. One trouble-making player causes chaos for his team when he tries to throw the first challenge. Later, two men and two women enter the Ruins, where they must fight for survival.
