Hit reality show "Survivor" is set to return for its 45th season this fall on CBS, the network announced last week.

The show teases 18 "determined new castaways" being split into three tribes of six as they form a new society Fiji.

This season "continues to define a bold new era of the series with the return of risky advantages, game-changing twists and a relentless pace that will push these castaways to their limits," the network said in a news release.

The long-running reality series has been a hit since premiering in 2000. Last season saw Yamil "Yam Yam" Arocho crowned as the champion and winner of $1 million.
