Twists/Changes

 * "One World" Format: The two competing tribes, Salani and Manono, will be competing against each other while living together on the same beach in a more indefinite time. After the Reward Challenge in Day 12, the tribes were separated.
 * Battle of the Sexes: The cast will be divided according to gender, similar to both Survivor: Amazon and Survivor: Vanuatu. Salani and Manono were the all-women and all-men tribes respectively, before the Tribal Shuffle on Day 12.
 * "Do-It-Yourself" Challenges: Similar to how a Reward Challenge in Survivor: Samoa was conducted, certain challenges would require the contestants to run the challenge themselves, with no host overseeing them.
 * Hidden Immunity Idols: Though there will be only one camp, there will still be two Hidden Immunity Idols, one per tribe. Once a person finds the other tribe's idol, they cannot use for themselves. Instead, they must give it to a member of the opposite tribe. Furthermore, for the first time, no clues would be provided.
 * Tribe Shuffle: The tribes were switch in Day 12, mixing the men and the women.
 * Early Merge: The tribes merged with 12 castaways

Episode Guide
 Notes: 

Combined Reward and Immunity Challenge After Kourtney's accident, Manono was given the chance to complete the challenge anyway, despite Salani being down one member or win by default. Manono chose to win by default, technically declaring them the winner of the challenge. Manono was the true winner of the Immunity Challenge, but eventually gave up immunity to Salani, effectively sending themselves to Tribal Council.
