Production
Jeff Probst stated during the Survivor: Caramoan reunion that he was leaving to film Survivor: Blood vs. Water on May 13, 2013. He stated a "game changing" twist would be involved. He then confirmed the season would begin airing on September 18, 2013, with a 90-minute premiere. Casting call was the same, and shortlist contestants included: contestant Ashley Underwood, who couldn't compete due to both her partner and her back-up partner being unable to play. Former  winner, Tom Westman, was asked but declined. Greg Buis from the original Survivor also declined the offer to appear again . Bobby Jon Drinkard from  and  participated in the casting, but was cut. Tom Buchanan and Lex van den Berghe, both from and, declined due the production of their new reality television program, Family Beef.

Twists

 * Returning Players: In mid-May 2013, it was revealed that this season would have returning players.
 * Couples Format: Players will be paired with a competing family member or loved one on the cast. Every castaway will be playing individually, so they will remain in the game even if their family member is voted out. This season, the pairs will be comprised of returning players and their loved ones, where the returnees would be put in one tribe, while all of their loved ones would be put in another.
 * Day Zero: The 10 pairs will be sent out at sunset to 10 different locations to live by themselves for the night. They will then all meet up to be officially welcomed by host Jeff Probst and start the game the next morning.
 * First Impressions: Moments after meeting each other, each team will vote one member off their tribe. They will be sent to Redemption Island.
 * Redemption Island: Anyone voted out will be sent there and will then compete in a three-person duel. The last place finisher in each contest is out of the game for good, while the top two remain. However, if someone’s loved one is still in the game they can take their loved one’s place before a duel.
 * Hidden Immunity Idol: The person who finishes first in each duel will also get to give a clue to the location of a Hidden Immunity Idol to any person from either tribe that they choose.
