Biomes (Below Zero)

This article is about Biomes in Below Zero. Click here for information on this subject in Subnautica.

Subnautica: Below Zero features a similar style of map as Subnautica, wherein the map is separated into individual biomes, each with their own unique set of landscapes, fauna, and flora and sometimes lore (e.g. the Koppa mining site).
