Survivor's 18 castaways who will compete on this fall's Survivor: Heroes vs. Healers vs. Hustlers edition have been formally announced.

CBS has revealed the identities of the castaways who will be fighting for $1 million on Season 35, which will premiere with a typical one-hour episode on Wednesday, September 27 at 8PM ET/PT.

The fall edition of Survivor, once again filmed on the Mamanuca Islands in Fiji, will feature three tribes, each comprised of six castaways, who possess similar characteristics that represent their profession or reputation, and how they are perceived by others.

The cast includes an Olympian, an NFL player, a bellhop, a diversity advocate, and a urologist.

Longtime Survivor host Jeff Probst introduced a preview video for Survivor: Heroes vs. Healers vs. Hustlers in late May -- during the reunion show for last season's Survivor: Game Changers -- that featured glimpses of some of the new castaways as well as an explanation of the significance behind each tribe's label.

"Heroes: They are heralded for their courage, their achievements, and ideals for which they stand," Jeff said.

"[Healers] receive gratitude for their acts of service in helping people heal their emotional and physical pain. [Hustlers] are respected for their work ethic -- 'Get it done, no matter what.' They stop at nothing to achieve their goals."

CBS also teased that Hustlers must earn their respect from others.

The castaways will attempt to outwit, outplay and outlast each other for the title of "Sole Survivor."
