SURVIVOR: WORLDS APART- For the first time in Survivor history, social class separates the tribes as 18 new castaways--including a former talent agent assistant, a Yahoo! executive, a barrel racer, and a sailing instructor--are split into White Collar, Blue Collar, and No Collar. This season also introduces a new twist: a one-time extra vote at Tribal Council. This potentially significant game-changer is revealed at the discretion of the castaway lucky enough to win the advantage at a contentious Survivor Auction. For this heated season, the fire-making tie-breaker challenge returns, not seen since Survivor: Gabon.
