Architect Bases

Alien Bases are ancient structures that will be located around the Arctic Mega Biome in Subnautica: Below Zero. They were built by the Precursors approximately one thousand years prior to the events of Below Zero. Their purposes vary, and it is unknown if any of them are focused on the studying of Kharaa, similar to those found in The Crater.

Bases

The Fabricator Base's location is currently unknown. It will contain a fabricator used to construct Al-An a new body.

The Shield Base's location is currently unknown. Its purpose is currently unknown, however the name suggests it has defensive capabilities.
