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 Almanac 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
Alien Research Site Zero will be found in a surface level mountain cave. Its purpose is currently unknown, although its upper section is capable of generating a shield for reasons unknown.

Sanctuary Zero is located in the Twisty Bridges. It serves as a resting place for the minds of Almanac, and is where Al-An's core is located. It houses a consciousness transfer device.

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