Edge of Extinction (twist)

is the major twist that appears in.

Concept
Jeff Probst admitted that over the years, Survivor had explored the strategic side of the game by way of Hidden Immunity Idols and advantages, but not much about the psychological impact it does on castaways. Probst stated: "none"

- 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. We've done a lot in the last few years about game play 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? That's where this idea was born; what if you play the game, and you get voted out, but you also have an option? It's not Redemption Island. It's not Exile. It's not the Outcast [twist from Survivor: Pearl Islands]. It's truly a situation where you're going somewhere where tribe life as you knew it on the island will seem wonderful, because on Extinction, you will have to work for everything. And with no certainty that you will get back in the game, it comes down to one question: how badly do you want this? How far will you want to push yourself? How curious are you to see what you're capable of?

Format
On paper, Extinction Island exactly shares the same premise as Redemption Island: A place where castaways who are voted out will be sent, waiting for a chance to return to the game. With Extinction Island however, there are no weekly duels; and the castaways still in the game are unaware of the island's existence.

Castaways who are voted out will be led to a path from Tribal Council where they will be given a choice whether or they choose to stay in the game without knowing the stipulations it would entail nor the certainty they will be returning at all, or choose to leave the game permanently. Those who opt to stay will be stranded on a desolate island with a shipwreck. If a contestant cannot handle the isolation any further, they may choose to withdraw by flying a white flag from a the ship's mast, after which a boat will pick them up, eliminating them from the game.

The manner of which the voted out survivors will be competing to re-enter the game remains to be seen.
