Survivor: Marquesas is the fourth season of the American CBS competitive reality television series Survivor. The sixteen contestants were divided into two preselected tribes of eight, Rotu and Maraamu. This was the first season where the contestants were not given any initial food, water, or matches. Also, the rules of individual immunity were changed so that a contestant who won immunity in a challenge was able to give it to another contestant. A new tiebreaker format was developed in preference of the past-used tiebreaker involving previous votes cast. The controversial new Purple Rock tiebreaker was used.
