At the bottom of the ocean floor lie The Biospheres. These weather-controlled domes once supported vast arrays of lifeforms, but have since been abandoned. Explore arid deserts, dark forests, and frozen tundras. But don't stay too late, as you are not alone out in the great abyss.
Venture into procedural dungeons deep within The Biospheres. Discover why the underwater domes were built and what inhabitants may lurk inside. Should you want to continue your exploration deeper underwater, you best not leave empty-handed.
It's dangerous to go alone. Bring a crew of up to 4 players to better your odds. Or, if you are feeling hardcore, you can venture off by yourself.
