|This article is about the Seabases'. You may be looking for the Abandoned Seabases.|
Seabases are installations created by the player through the use of the Habitat Builder tool.
Habitat Compartment Modules are available to allow the creation of unique Seabases. Their primary application is to provide an area where the player can return for oxygen, and to serve as an alternative to Lifepod 5 as a base of operations. In Survival and Freedom mode, the player will return to the last Seabase they visited when they die (unless they last visited a Cyclops or Lifepod 5).
The main benefits of a Seabase are the ability to have more storage space, grow food, access to Appliances not available in the Lifepod, and to add aesthetic options. Seabases also grant the player a safe haven far away from the Safe Shallows they start in.
The player will start out with most of the blueprints they need for a basic Seabase; at bare minimum one needs a Compartment, a Hatch, and a power generator (the Solar Panel is unlocked by default). The initial compartment must be built on the ground, but any attached compartment can overhang without any issue, allowing bases to be built over cliffsides. While modules such as the Multipurpose Room have to be discovered first, this beginner base will still allow for the basic functions of Oxygen resupply, and a place to put storage and a spare Fabricator. The player can then choose to relocate or expand once they've gathered more Blueprints.
Abandoned Seabases can be found at the center and on the tops of the mountains of the Floating Island, Jelly Shroom Caves, and Deep Grand Reef. These Abandoned Seabases provide blueprints for additional base components that the player doesn't have access to by default, such as the Multipurpose Room or the Observatory. The remaining base components, as well as power generators, appliances and furniture, can be found in various Wrecks.
Hull Integrity Edit
Hull Integrity refers to 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 on the ends of Compartment modules.
When the hull integrity of a Seabase is less than or equal to 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 Edit
Energy can be provided to a Seabase by building various types of generators near or inside the Seabase. Any number or combination can be used. Appliances such as the Fabricator will drain energy from the Seabase.
There are four generators available to power Seabases:
- Solar Panels, which work best near the surface
- Bioreactors, which consume any organic matter for power
- Thermal Plants, which collect heat energy (use near Lava Geysers and Black Smokers)
- Nuclear Reactors, which consume Reactor Rods made from Uranium
The following Appliances draw power from the Seabase:
- Battery Charger
- Power Cell Charger
- Modification Station
- Water Filtration Machine
- Vehicle Modification Station (fabricator only)
- Scanner Room (fabricator only)
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 Edit
- Find a suitable flat piece of land.
- Equip the Habitat Builder, click the RMB to bring up a crafting menu.
- In Habitat Compartments tab, select the desired module.
- Look at the desired building place (the outline of the module will become green if the location is valid).
- Adjust the rotation by scrolling the mouse wheel.
- Place the module by clicking the LMB.
- Once placed, hold the LMB to finish the building process.
- 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. If enough space is available, all materials used to create the module will be returned to your Inventory one item at a time. Note that you must first deconstruct everything attached to a Basic Compartment or Multipurpose Room before you are allowed to deconstruct it.
The Seabase's AI plays various messages that correspond to different circumstances.
Welcome message Edit
This message will play upon entering your Seabase.
- The message does not play every time the player enters their Seabase; it appears that the player must be outside their Seabase for a certain period of time before it will play again.
If no power source is connected to your Seabase, this message will play upon entering instead of the Welcome message.
- This message is also triggered when an appliance or room reduces a Seabase's power to 0.
Power restoration Edit
When the power to the Seabase is restored, the AI will play this message.
Hull integrity restoration Edit
This message plays after the player completely repairs their Seabase.
- The message can also be triggered after flooding has occurred by entering an undamaged module and sealing its entrances/exits with bulkheads.

Future Updates Edit
- Future updates will allow plants to produce Oxygen naturally, eliminating the immediate need for power to provide a Seabase with Oxygen.
- This has since been delayed.
- 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.
- Attacks on Seabases by creatures may be added in future updates.
