Architect Bases

This seems new This article contains information that is updated for the latest Experimental Version of Subnautica. Players using stable mode may find this information inaccurate.

Precursor Bases are in-development structures. They were built by the Precursors around one thousand years ago. Four Precursor Bases are to be implemented in total, on the Mountain Island, in the Lava Castle, the Lost River, and the Active Lava Zone. There are also 3 Precursor Caches in the game although more are planned to be implemented.

Locations

The Quarantine Enforcement Platform is present on the Mountain Island embedded into the rock face. The purpose of this base was to shoot down "all vessels without proper clearance".

The Disease Research Facility is located in the Lost River. Its purpose was to conduct research on the Carar bacterium. It was destroyed by an escaped Sea Dragon Leviathan, and thus is suspended at a crooked angle in a giant cavern, surrounded by skeletal remains.

The Precursor Thermal Power Generator is found within the Lava Castle, where it powers the majority of the precursor technology.

The Primary Containment Facility will be located in the Active Lava Zone, and is where the Sea Emperor will be encountered. This Precursor Base will also feature teleporter rooms. (*)

Trivia

• On a Trello card, the Quarantine Enforcement Platform was referred to as the Precursor G.U.N, or "Precursor Global Defense System". This is a developer joke as "guns are not allowed in Subnautica" yet the model's name is Precursor Gun.
• Models for the Array and various parts of bases were accidentally revealed during an experimental patch that added them into the entity gallery. A user on the forums revealed screenshots of the bases and they spread quickly. After seeing this, the developers quickly removed them and asked pictures of them to be prevented from spreading; they called it "a huge screw up". 
• Precursor Teleporters will be present in each major biome and at important locations - they will all link to the Primary Containment Facility.
