In the vast, underwater world of Subnautica, resources are scarce, and space is at a premium. This is where the Multipurpose Room comes into play, offering a versatile solution to both storage and functionality. Let's dive into the details of this essential base component, as outlined on the Subnautica Wiki.
Understanding the Multipurpose Room
The Multipurpose Room, often abbreviated as MPR, is a modular base component introduced in the Subnautica: Below Zero expansion. It's designed to provide a flexible, expandable space that can serve multiple purposes, from storage to research to even housing your trusty Seamoth.
Crafting and Placement
To craft a Multipurpose Room, you'll need to gather several resources, including Titanium, Glass, and Rubber. The recipe can be found in the Fabricator, once you've unlocked the necessary blueprints. Once crafted, the MPR can be placed on any flat surface, both on land and underwater, providing a stable, secure structure.

Modules: The Heart of the MPR
The true power of the Multipurpose Room lies in its modular design. Each MPR can accommodate up to four modules, which can be swapped out to suit your current needs. Here are some of the modules you can expect to find:
- Storage Module: Provides additional storage space for your items.
- Research Table: Allows you to conduct research on collected samples and blueprints.
- Vehicle Upgrade Console: Enables you to upgrade your Prawn Suit and Seamoth.
- Growbed: A hydroponic system for growing plants and producing food.
Expanding Your Multipurpose Room
Once you've built your first Multipurpose Room, you might find that you need more space. Luckily, the MPR can be expanded using additional room components. These include:
- Multipurpose Room Extension (adds two additional module slots)
- Multipurpose Room Double Extension (adds four additional module slots)
These extensions can be placed adjacent to your existing MPR, allowing you to create a sprawling underwater base tailored to your needs.

Tips for Effective Use
Here are some tips to help you make the most of your Multipurpose Rooms:
- Place them strategically: Consider where you'll need storage, research, or vehicle upgrades most.
- Expand when necessary: Don't be afraid to add extensions as your base grows.
- Swapping modules: Regularly review your modules to ensure they match your current needs.
The Multipurpose Room is a versatile tool that can greatly enhance your Subnautica experience. By understanding its capabilities and optimizing its use, you'll find that your underwater adventures are smoother and more enjoyable. Happy diving!
