Multipurpose Room (Below Zero)

Overview
The Multipurpose Room is a Seabase Module in Subnautica: Below Zero. It provides significantly more interior space for movement compared to the I Compartment or X Compartment, though it is smaller than the Large Room.

Construction & Placement
The Multipurpose Room is constructed using the Habitat Builder. It can be placed on top of a Foundation or attached directly to another Seabase module.
- Horizontal Connection: When connected horizontally to another module, a small corridor segment is automatically generated.
- Vertical Stacking: Multipurpose Rooms can be stacked vertically. Players must build ladders inside to access multiple floors.
- Expansion: Side panels allow expansion with other modules. However, side panels at 45-degree angles to the construction direction cannot be expanded from.
- Glass Dome: A Multipurpose Room Glass Dome can be placed on top, but this prevents further vertical stacking.
Hull Integrity Mechanics
Every Multipurpose Room added reduces total Hull Integrity by -1.25 (the game interface may display -1.3 due to rounding).
- The first piece of a seabase starts with +10 Integrity.
- If built as the first piece at surface depth, the net integrity is approximately 1.8 (+10 - 1.25).
Panel Limitations
- Ladders: Can be placed on all five floor and ceiling boxes if an adjacent Seabase module exists for connection.
- Windows & Reinforcements: Can be placed on all eight side panels.
- Note: North, South, East, and West sides provide double the Hull Integrity bonus from reinforcements compared to the 45-degree sides. This may be a bug.
- Alien Containment Expansion Hatches: Can be placed on all eight side panels.
- Connection Restrictions: Cannot be connected to the Large Room using a Ladder.
Crafting
The blueprint is unlocked by scanning Multipurpose Rooms found at Outpost Zero or Delta Station. It is crafted exclusively with the Habitat Builder.
