The full map and biomes of Subnautica: Below Zero

Subnautica: Below Zero is a delightful exploration and survival game with a mass of land and water for players to explore.

There is so much to do and so much to see in Subnautica: Below Zero. The openness of the world is astounding. Players are able to travel above water, under water, into caves, into structures, and more.

The map is gigantic. There is no other way to describe it. Trying to find a certain area can be a bit daunting. A map and a list of all the biomes should be enough to take the weight off an explorer's shoulders.
