Survival of the Fittest is a multiplayer online survival arena spin-off based on ARK: Survival Evolved in which up to 72 players compete to be the last player surviving on the island. Game modes include free-for-all and team play. The game progresses at an accelerated rate with leveling, resource gathering, and taming taking considerably less time than in the original ARK game. Evolution events will happen over the course of the game that can help or hinder players in their competition for survival.
On August 1, 2016 Survival of the Fittest was re-integrated into Survival Evolved and is no longer a standalone game.
