I Compartment (Subnautica)

The Corridor or I-Corridor is the most basic Seabase module.

It is constructed with the Builder and placed on top of a Foundation. It is possible to build off the foundation or remove the foundation afterwards. At the surface a Corridor has an integrity level of nine and every Corridor added reduces the integrity by one level. It can be rotated before placing it by pressing Q or E.
