Arat
Arat is the alien planet ARK 2 is set on. It is a harsh world populated by a mix of familiar dinosaurs and unfamiliar alien fauna, and it is the home territory of the Aratai faction.
Setting Shift
Moving to a named alien planet is one of ARK 2's more concrete changes from ARK: Survival Evolved's broader 'ARKs' setup. Arat is a single, specific place with its own story, its own politics, and its own indigenous survival pressures, rather than a generic procedural island.
