Players in the game control a tribe of dinosaurs - the "character" in the game is comprised of several individuals. Each dinosaur has four Attributes - Think, Fight, Run, and Endure - with values assigned from a standard array. Dinosaurs also have Traits and talents (for example, claws, horns, or spikes). Play proceeds in phased rounds with each player taking a turn in sequence. As one player gains the spotlight, other players assume the roles of Adversary and Judge. Play proceeds with the use of tracking tokens and narrative development.
