Ark: Survival Evolved will release on August 8

Ark: Survival Evolved (stylized as ARK) is an action-adventure survival video game in development by Studio Wildcard in collaboration with Instinct Games, Efecto Studios, and Virtual Basement. It is scheduled to be released for PlayStation 4, Xbox One, Microsoft Windows, OS X and Linux in August 2017. 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 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.
Development began in October 2014. The development team conducted research into the physical appearance of the animals, but took creative license for gameplay purposes. One of the game modes, Survival of the Fittest, was released as a free standalone game in March 2016. Egypt-based developer Instinct Games was hired to facilitate the game's development. Several expansions to the game have also been released as downloadable content: The Center, Primitive Plus, Scorched Earth, and Ragnarok.
