 * Tribe Expansion: On Day 11, a third tribe was introduced. At the Tribe Switch, the castaways were informed they would switch into three tribes instead of the regular two. On Day 11, the Xaio tribe was introduced.
 * Hidden Immunity Idol: Like previous seasons, at least one Hidden Immunity Idol is hidden in each tribe's camp.
 * Returning Players: As implied by the theme, eleven former players returned to compete against eleven new castaways.
 * Fake Letters: While Smrxi sent out letters for the Favorites, it was revealed in the letter that two people got a fake letter. Those people were Mxtthxvv and Luvcharley.
