Players attempt to shepherd their chosen dinosaurs through an ever-changing environment. Each player attempts to alter the environment during every game round. Extinction looms for those who can not survive in the current environment. Even those that can survive the environment need to survive a round of combat from opposing player's dinosaurs.
