Bulkhead (Subnautica)

The Bulkhead is a Seabase module. It is constructed with the Habitat Builder and can only be placed inside seabases at the junction between two modules.

The Bulkhead increases integrity level by +2. The Bulkhead can stop flooding from going into another section of a base.

Bugs

If an open bulkhead is constructed between a corridor and connected room/moonpool, and the latter is removed, the player can swim into their base. Conversely, if they enter their base through a hatch and exit through the bulkhead, the player will walk outside on the sea floor as if it were part of their base's interior; the player's footfalls will also sound metallic.
