Today Studio Wildcard, the developer behind Ark: Survival Evolved, released the game's second expansion called Aberration.
You can download it right now on Xbox One, Steam, and PlayStation 4. Survivors wake up on the Aberration, a derelict, malfunctioning Ark featuring an elaborate underground biome. What's different about this map is that extreme radiation and environmental hazards require increased attention. You have to be careful where you venture. Exploring the world is also more treacherous because the caves house new challenges and creatures.
