Seabases (Subnautica)

Seabases are installations created by the player through the use of the Habitat Builder tool.

Habitat Compartments Modules are available to allow the creation of unique Seabases. One of their primary applications is to provide an area where the player can return for Oxygen and serve as an alternative to Lifepod 5 as a base of operations.

Seabases can be customized in the same way as the Cyclops through the installation of Lockers, Wall Lockers, Fabricators, Benches, Signs, and Aquariums and much more.

Abandoned Seabases can be found at the center and on the tops of the mountains of the Floater Island, Jelly Shroom Caves, and Deep Grand Reef.

Hull Integrity


Hull Integrity refers the ability of your Seabase to withstand the pressure of the surrounding water. The majority of the modules will lower the integrity once added but the amount will vary by module. As Seabases are built at a greater depth the integrity reduction caused by each module will increase. Hull integrity can be increased by constructing Reinforcement panels, placing your Seabase on or near a Foundation (foundations built on top of rooms will still provide their benefit), or installing Bulkheads.

When the hull integrity of a Seabase reaches zero, it will begin to form hull breaches. Any corridor or room that is connected to the breach will fill but Bulkheads allow the player to compartmentalize the base and prevent floodwaters from moving between compartments. However, if the integrity remains below zero then eventually every compartment will develop a leak and the base will fill completely with water. To avoid this, quickly increase the integrity and fix all hull breaches in the base using a Repair tool.

Energy Usage
Energy can be provided to a Seabase by building various types of generators near the Seabase. Appliances such as the Fabricator will drain energy from the Seabase.

Seabases do not require energy to operate devices in Freedom Mode. A notable exception to this is the ability to dock a Seamoth in a Moonpool, which does require power.

Oxygen
Seabases produce Oxygen natively, but require power to do so. If the power is depleted, the Seabase will slowly lose oxygen, until it is completely gone.

How to Build a Seabase

 * 1) Find a suitable flat piece of land.
 * 2) Equip the Habitat Builder, click the RMB to bring up a crafting menu.
 * 3) In Habitat Compartments tab, select the desired module.
 * 4) Look at the desired building place (the outline of the module will become green if the location is valid).
 * 5) Adjust the rotation by pressing Q or E or by scrolling the mouse wheel.
 * 6) Place the module by clicking the LMB.
 * 7) Once placed, hold the LMB to finish the building process.
 * 8) Go to Step 2 and repeat.

If you want to deconstruct a Seabase module, equip the Habitat Builder and hold "Q" while facing the module. The materials used to create the module will be returned to your Inventory. Note that you must first deconstruct everything attached to a Corridor or Multipurpose Room before you are allowed to deconstruct it.

Sounds
The Seabase's AI makes two different sounds. Those are:

Welcome message
This message will play upon entering your seabase or seamoth.

Power restoration
When the power to the Seabase is restored, the AI informs you about it.

Available Modules

 * Please note that negative changes to hull integrity do increase with depth. For more information see Hull Integrity.

Future Updates

 * Future updates will allow plants to produce Oxygen naturally, eliminating the immediate need for power to provide a Seabase with Oxygen.
 * A Docking Hatch for the Cyclops is planned to be added in future updates, allowing the player to physically connect their Cyclops with their Seabase. You'll be able to connect a special corridor with the Cyclops, which will act like a hatch.
 * A Waterlock is shown in the concept art, that would allow the player to connect the Alien Containment with the exterior of their Seabase. The exact purpose for this is unknown, and it is currently uncertain if it will be added in future updates.
