<label>Coordinates</label> <group> <label>Point of Interest</label> </group> <label>Music</label> </infobox> Architect Bases are ancient structures built by the Architects on Planet 4546B roughly one thousand years prior to the events of Subnautica. Most major installations are located within The Crater, with a number of smaller, auxiliary ones being located in Sector Zero. Additionally, minor installations—known as caches—can be found in both areas. With the exception of the Disease Research Facility, all bases and caches are in working order, with some still in active operation due to their automated nature.

Trivia

• Models for the Quarantine Enforcement Platform 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". 
• The small structures that surround the Primary Containment Facility are known as Sonic Deterrents. Lore-wise, they are designed to protect the bases from large creatures, but do not function in gameplay.
