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 Room directly (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.
