Survivor is bringing back its winners for its upcoming 40th season.

For the CBS competition series' 20th anniversary edition, the theme is "Winners at War," uniting the most memorable, heroic, and celebrated champions for the biggest battle in the show's history. These returning players will compete to once again to earn the title of Sole Survivor and the largest prize in reality show history — $2 million.

The champions will compete in epic challenges and face the return of Edge of Extinction (which gives voted-out players a second chance to win). There's also a new element, fire tokens, currency which will "add more complexity" to the game.

"To celebrate and honor this momentous 20-year milestone, we created the biggest battle in Survivor history!" executive producer and host Jeff Probst said in a statement. "For the first time ever, 20 winners, who have masterfully proven they can outwit, outplay and outlast in this game, will face off to determine who is the greatest player of all time!"
