Ark: Survival Evolved (stylized as ΛRK) is an action-adventure survival video game developed by Studio Wildcard in collaboration with Instinct Games, Efecto Studios, and Virtual Basement. It was released in August 2017 for PlayStation 4, Xbox One, Microsoft Windows, OS X and Linux. In the game, players must survive being stranded on an island filled with roaming dinosaurs and other prehistoric animals, natural hazards, and potentially hostile human players.

The game is played from either a third-person or first-person perspective and its open world is navigated on foot or by riding a prehistoric animal. Players can use firearms and improvised weapons to defend against hostile humans and creatures, with the ability to build bases as defense. The game has both single-player and multiplayer options.
