Survivor: Cambodia

Survivor: Cambodia, also known as Survivor: Cambodia - Second Chance, is the 31st season of Survivor.

In a change to previous installments, Survivor fans were given the chance to vote for who would appear on the cast through social media.

Development
On May 6, 2015, an announcement was made that for the first time in Survivor history, fans had the ability to vote for and assemble the cast for the next season. Through social media, fans voted for ten men and ten women from a pool of 32 former castaways, each of whom had played only once. Voting ended one hour into the finale, where all of the nominees were present at the reunion with their luggage already prepared for filming.

The final roster of 20 was revealed at the end of the show, and were flown to Cambodia immediately afterward. It should be noted that this season, which will be the 32nd to be produced, will be aired as the 31st season, while the 31st season to be produced, which was filmed during the original run of Worlds Apart, will be slated as the 32nd season.

Filming commenced in May 31, which also marked the 15th anniversary of the series' debut episode,.

Second Chance Vote
Immediately following the episode, a shortlist of 32 candidates, all one-time contestants that did not win the game, was posted on CBS.com. Contestants were nominated from across 16 seasons, ranging from the first installment,, to the most recent,. Fans were allowed to vote starting from the end of the said episode until the Worlds Apart finale.

At the time of the launch of the poll, two nominated contestants from Worlds Apart, Mike Holloway and Carolyn Rivera, were still in the game. Jeff Probst explained that if either one of them eventually wins their season and garnered enough votes to return, they would be ineligible to compete for this season, giving their spot to the candidate of their gender who garnered the 11th highest amount of votes. This did end up being the case, with Mike winning Worlds Apart and finishing in the top 10.

Twists/Changes

 * Returning Players: 20 former contestants, all of whom have played only once and did not win the game, and whom were determined by public vote, returned for a second chance.
 * Hidden Immunity Idol: The Hidden Immunity Idols for this season will look different from each other, making it more difficult for the players to know if the idols are real or fake. Also, for the first time, the idols will be hidden in the middle of the challenges, while the clues will be hidden at camp. This is an idea originally proposed by Entertainment Weekly columnist Dalton Ross.
 * Third Tribe: For the first time, a third tribe will be introduced later in the game before the merge.
 * Challenges: The challenges for this season will also feature the Second Chance theme, as production will incorporate past challenges in which the cast has previously participated in their corresponding seasons. The list of challenges includes some that they have lost before, but not exclusively.
 * Impromptu First Tribal Council: The tribe that loses the first Immunity Challenge will be immediately sent to Tribal Council after the challenge.
