ARK: Survival Evolved was a mega success on the PC through Steam Early Access, and now it will spread its wings into iOS and Android... completely free.
ARK sees you dropped onto an island where you're tasked with surviving the elements, other players, and dinosaurs. You'll need to hunt down materials, craft items, and survive. You'll level up, learn new skills, and explore the world of ARK as a full free-to-play game on iOS and Android, compared to the PC and consoles where the game costs money.
A single ARK server hosts 60 players, with more than 80 dinosaurs across the lands that you can either fight, or tame and use yourself. If you want an ad-free experience, you can buy the Primal Pass subscription which includes free gifts, and a reserved server slot.
