Multipurpose Room
The Multipurpose Room is the primary interior space in Subnautica 2 seabases, providing a large volume for placing fabricators, storage, and equipment.
Quick Info
Description
The Multipurpose Room is the heart of your seabase. It offers a generous interior volume where you can install fabricators, storage lockers, water filtration machines, bioreactors, and other equipment. Most functional bases center on one or more Multipurpose Rooms linked by Corridors. Each room costs integrity, so balance size with reinforcement.
How to Craft
Multipurpose Rooms are built with the Habitat Builder. Once a Foundation is placed, aim at a connection point and select the Multipurpose Room to snap it on top or beside existing modules.
