Survivor: Gabon - Earth's Last Eden cast by Monty Brinton/CBS Survivor: Gabon - Earth's Last Eden cast by Monty Brinton/CBS

CBS has unveiled the cast for Survivor: Gabon - Earth's Last Eden, and among the 18 embarking on the African adventure are a pin-up model (Hellooo, first-ever HD Survivor!), a professional gamer, a wedding videographer (yeah... his skills won't come in too handy) and Olympic gold medalist track star Crystal Cox. (Olympic athleticism apparently is the new bartending in reality-TV land.)

The ages for the crowd span 22 (sales girl Kelly and joystick jockey Ken) to 61 (Gillian the retired nurse). ( Eyeball a larger photo of the cast here.)

In its press release, CBS promises "extreme conditions" and player interactions with "wildlife such as elephants and gorillas." Host Jeff Probst says that, befitting this cycle's subtitle, "Good vs. evil emerges as a major theme.... I think the audience will quickly identify with one group or the other."

Survivor: Gabon premieres Thursday, Sept. 25, from 8 to 10 pm/ET. - Matt Mitovich
