'Survivor: Edge of Extinction' Castaways Revealed

CBS announced the cast for Survivor: Edge of Extinction on Thursday, ahead of the new season's debut in late February. The season will include 18 castaways, including four returning players battling for $1 million.

The castaways will be split into two tribes, the Manu Tribe and the Kama Tribe, who will compete each week to avoid heading to a Tribal Council to vote a member out. After each castaway is cast away, they are given the opportunity to leave for good, or try another chance at the $1 million prize.

If the player chooses to keep playing, he or she is sent to Extinction Island, a barren wasteland that will test the player's endurance. They will be stuck there until the producers give them an opportunity to come back. If living on the island proves to be too much, they can raise a white flag and leave Survivor.

"As we continue to evolve the show, it's really important to us that we continue to see how far we can take this experiment," host and executive producer Jeff Probst told The Hollywood Reporter. "We've done a lot in the last few years about gameplay and advantages and twists and really wanting players to come in and play strategically. Lately, it's also been occurring to me that we should try to get a little deeper psychologically, a little deeper spiritually. Let's see how far people want to go. Is there a possibility of the spiritual death and rebirth that you seek in life, where you realize something deeper about yourself?"

Details of what life will be like on the isolated island are still unknown. Fans will have to tune in on Wednesday, Feb. 20 at 8 p.m. ET on CBS.
