ARK: Survival Evolved is now free to claim on the Epic Games store. You'll be able to permanently add it to your library as long as you claim it by June 18th at 5 PM. At that point, two games will take its place - Pathway from Robotality/Chucklefish and The Escapists 2 from Team 17.

The dinosaur themed sandbox survival game developed by Studio Wildcard was somewhat of a sensation during the survival craze of a few years ago. ARK: Survival Evolved sold several million units between PC, Xbox One, PlayStation 4 and Nintendo Switch, and it later appeared on mobile platforms as well.
