Jeff Probst has explained the new rules about second chances and quitting for Survivor: Redemption Island – and now CBS is introducing the new cast. Well, almost: Two of the 18 contestants won't be revealed right away because they're previous players who will return for a chance to redeem themselves. But here are the other 16, who will be a part of two tribes – Ometepe and Zapatera – when CBS's Survivor returns to Nicaragua for the premiere of Redemption Island on Feb. 16 (8 p.m. ET):
Andrea Boehlke, 21, student: "I've been raised on a farm my whole life," she says, "and I've been hunting since I was 12 and fishing and camping, so I'm not too worried about the elements."
Mike Chiesl, 31, former marine: "The great thing about Survivor, though, is nobody's shooting at you," says the Iraqi vet. "I'll take that over going on deployment to Iraq any day."
Matt Elrod, 22, pre-med student: "Out here when people feel alone and isolated," he says, "I have a warmth towards people that I think they'll respond to and want to keep me around and probably trust me."
Ralph Kiser, 44, farmer: "I'll make you laugh your ass off," he says, "because I say things not proper."
Francesca Hogi, 36, attorney: "There's a mean girl inside of me," she says. "I terrorized some girls in elementary school."

Kristina Kell, 46, law student: "I'm a complete package," she says.

Grant Mattos, 29, yoga instructor: "[I played professional football for] the San Diego Chargers, the Denver Broncos and the Tennessee Titans."
Stephanie Valencia, 25, waitress: "I'm always right even when I'm wrong," she says. "I always get my way just because I know how."
Phillip Sheppard, 52, technology executive: "I have a terrific smile and when I really let it pop, you look at that smile and it disarms you," he says.
Sarita White, 36, visual effects producer: "It's a good group," she says of her costars, "so that of course makes me excited but also like, what's the catch?"
Natalie Tenerelli, 19, professional dancer: "Of course I'm going to use my girly instincts," she says. "I can be flirtatious and I hopefully will know when to stop."
Julie Wolfe, 50, firefighter: "I'm newly divorced. I have 100 percent custody for two children and I'm paying alimony, I'm paying child support and my house is in foreclosure," she says.
Ashley Underwood, 25, nurse: "I really think pageants get a bad rap sometimes," she says, "but in all honesty, it really takes a lot of mental toughness."
