It may be prudent to separate work and leisure spaces to maximize productivity. Treat this space as your home, but never forget that it is not.

The Multipurpose Room is a Seabase Module. It provides a much larger space for movement than the Basic Compartment or the X Compartment.

It is constructed with a Habitat Builder and can be placed on top of a Foundation or it can be attached to a Seabase module. When the Multipurpose Room is horizontally connected with another Seabase module, a junction forms in-between. When the Multipurpose Room is connected vertically with another Multipurpose Roomdirectly (as in, without using a Vertical Connector), they will form one larger Multipurpose Room. However, each floor cannot be accessed without adding in a ladder.

Every Multipurpose Room added to a seabase reduces the Hull Integrity by -1.25 (The game shows -1.3 because it rounds the number. It is functionally -1.25). The first piece of a seabase starts with +10 Integrity, thus if a Multipurpose Room is the first piece built it gets +10 - 1.25, or 1.8 (rounded) at surface depth.


  • Hatches can be placed on all eight of the side-panels.
  • Windows can be placed on all eight of the side-panels.
  • Ladders can be placed on all five floor and ceiling boxes if there is an adjacent seabase module to connect.
  • Reinforcements can be placed on all eight of the side-panels. Currently, the North, South, East, and West sides give double the Hull Integrity bonus of the 45 degree sides (This may be a bug).
  • The Multipurpose Room can be expanded with other modules from its side-panels. However, the side-panels that are on a 45 degree angle to the module construction cannot be expanded from. The Multipurpose Room can be expanded vertically using a second Multipurpose Room.


The Multipurpose Room blueprint can be acquired by scanning a Multipurpose Room at any of the Degasi Seabases.

  • Concept art shows that the ceiling of the Multipurpose Room was also intended to become a window, thereby giving a glass ceiling akin to the small ones that can be made in X Compartments.
  • The Multipurpose Room was originally called Room.
