'''Seabases''' are installations created by the player through the use of the [[Habitat Builder]].


A '''Seabase''' provides an area where the [[player]] can return for oxygen, and serves as an alternative to [[Lifepod 5]] as a base of operations. Within a '''Seabase''', the player can construct additional storage space, grow food, access [[Interior Modules|Appliances]] not available in Lifepod 5, and add aesthetic options. Thus '''Seabases''' provides safe havens away from the [[Safe Shallows]] the player starts in.

Thus Seabases provide safe havens away from the [[Safe Shallows]] the player starts in.


In all [[Game Modes]] except Creative Mode, entering a '''Seabase''' secures the player's inventory, so if the player dies, they will return to the last '''Seabase''' they visited and keep all the items in their inventory that they had when they were there (unless they later enter a [[Cyclops]] or Lifepod 5).
In all [[Game Modes]] except Creative Mode, entering a Seabase secures the player's inventory, so if the player dies, they will return to the last Seabase they visited (Lifepod 5 and a [[Cyclops]] also count as Seabases for this purpose) and keep all the items in their inventory that they had when they were there. This occurs even if they die while inside the base in question: thus, quickly building a single [[I Compartment (Subnautica)|I Compartment]] and a [[Hatch (Subnautica)|Hatch]] on the seabed can be a valid tactic to secure the player's inventory if they are about to die.


The player will start out with most of the blueprints they need for a basic '''Seabase'''; at bare minimum one needs a [[Basic Compartment|Compartment]], a [[Hatch]], and a power generator (the [[Solar Panel]] is unlocked by default). The initial compartment must be built on or near the ground (or on a [[Foundation]], which is not necessary but provides a flat surface to work with), but any additional compartments can overhang without any issue, allowing bases to be built over cliffsides. The player can expand once they've gathered more [[Blueprints]].{{ExtraSpoilersection|[[Degasi Seabases]] can be found at the center and on the tops of the mountains of the [[Floating Island]], [[Jellyshroom Cave]], 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]] and the [[Observatory]]. Other base components, power generators, appliances and furniture, can be found in [[Wrecks]].}}

Despite their name, '''Seabases''' can be built on land. When on land, [[Hull Integrity]] is not a factor, and can be built without the need of additional [[Reinforcement]]s, [[Foundation]]s, or [[Bulkhead]]s. Power is still needed for them to operate, however.

Power is still needed for them to operate, but not to provide [[Oxygen|oxygen]].

== Hull Integrity ==
{{Main|Hull Integrity}}
[[File:Seabase interior.png|thumb|220x220px]]
[[Hull Integrity]] refers to the ability of the player's Seabase to withstand the pressure of the surrounding water, and as a mechanic slows the expansion of the Seabase. A Seabase starts at 10 integrity, but the majority of the modules will lower the integrity once added with the amount varying 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 a 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 begin flooding with water. Bulkheads can compartmentalize the base and prevent floodwaters from moving between compartments, but if the integrity remains below zero then eventually every compartment will develop a leak and the base will fill with water. To avoid this, quickly increase the base's integrity (by either adding strengthening components or removing weak components) and fix all hull breaches in the base using a [[Repair Tool (Subnautica)|Repair Tool]].

A Seabase that receives damage to its exterior will also spring leaks, but the hull integrity will be unaffected. This is most likely to occur if the player hits the base with a [[Cyclops]], as aggressive [[Fauna]] cannot damage bases. In this case, leaks will be limited to only the module that was hit and will not spread, making Bulkheads an effective method of preventing widespread flooding.
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 (either by adding strengthening components, or removing weak components) and fix all hull breaches in the base using a [[Repair Tool]].

A '''Seabase''' that receives damage to its exterior (or even a knife hit from inside) will also spring leaks, but the hull integrity will be unaffected. Therefore, bulkheads are more effective at sealing off flooding if the base comes under attack.


== Energy Usage ==
== Energy Usage ==
[[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''':
There are currently four generators available to power Seabases:
* [[Solar Panel]]s, which work best near the surface
* [[Solar Panel (Subnautica)|Solar Panel]]s, which work best near the surface
* [[Bioreactor]]s, which consume any organic matter for power
* [[Bioreactor (Subnautica)|Bioreactor]]s, which consume any organic matter for power
* [[Thermal Plant]]s, which collect heat energy (use near [[Lava Geyser]]s and Black Smokers)
* [[Thermal Plant (Subnautica)|Thermal Plant]]s, which collect heat energy (use near Lava Geysers and Black Smokers)
* [[Nuclear Reactor]]s, which consume [[Reactor Rod]]s made from [[Uraninite Crystal]]
* [[Nuclear Reactor (Subnautica)|Nuclear Reactor]]s, which consume [[Reactor Rod (Subnautica)|Reactor Rod]]s made from [[Uraninite Crystal (Subnautica)|Uraninite Crystal]]s
Bioreactors and Nuclear reactors need to be built inside a [[Multipurpose Room]]. Solar Panels and Thermal Plants need to be built outside, but can be connected to the base via [[Power Transmitter]]s if not directly attached to the base.
Bioreactors and Nuclear Reactors are built inside a [[Multipurpose Room (Subnautica)|Multipurpose Room]] or [[Large Room (Subnautica)|Large Room]]. Solar Panels and Thermal Plants are built outside and can be directly attached to the base or connected via [[Power Transmitter (Subnautica)|Power Transmitter]]s if the distance is too great.


'''Seabases''' do not require energy to operate devices in [[Game Modes|Creative Mode]]. A notable exception to this is the ability to dock a [[Seamoth]] in a [[Moonpool]], which does require power.

== Oxygen ==
* [[Scanner Room]] (fabricator only)
Seabases automatically produce [[Oxygen]] as long as there is power supplied, and can be used as a remote oxygen source outside the base through a [[Pipes (Subnautica)|Base-attached Air Pump]] and Pipes. If the power is depleted, the Seabase will slowly lose oxygen until it is completely gone.

If the player wants to deconstruct a '''Seabase''' module, equip the Habitat Builder and hold {{Key|Q}} ({{Key xbox|dpaddown}} on Xbox One) while facing the module. If enough space is available, all materials used to create the module will be returned to the player's [[PDA|Inventory]], one item at a time. Note that everything inside the module and attached to the outside of the module must be deconstructed before the module can be deconstructed.

This article is about {{#explode:Seabases (Subnautica)|(}} in Subnautica. [[{{#explode:Seabases (Subnautica)|(}} (Below Zero)|Click here]] for information on this subject in Below Zero.
This article is about the Seabases. You may be looking for the Degasi Seabases.

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

A Seabase provides an area where the Player can return for oxygen and serves as an alternative to Lifepod 5 as a base of operations. Within a seabase, the player can construct additional storage space, grow food, access Appliances not available in Lifepod 5, and add aesthetic options. Thus Seabases provide safe havens away from the Safe Shallows the player starts in.

In all Game Modes except Creative Mode, entering a Seabase secures the player's inventory, so if the player dies, they will return to the last Seabase they visited (Lifepod 5 and a Cyclops also count as Seabases for this purpose) and keep all the items in their inventory that they had when they were there. This occurs even if they die while inside the base in question: thus, quickly building a single I Compartment and a Hatch on the seabed can be a valid tactic to secure the player's inventory if they are about to die.

The player will start with most of the blueprints they need for a basic Seabase; at the 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 or near the ground (or on a Foundation, which is not necessary but provides greater Hull Integrity and a flat surface to work with), but any additional compartments can overhang without any issue, allowing bases to be built over cliffsides. The player can acquire Blueprints which allow additional module types to be created.

Spoiler alert: The following section contains story related material.

Degasi Seabases can be found at the center and on the tops of the mountains of the Floating Island, Jellyshroom Cave, 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 and the Observatory. Other base components, power generators, appliances and, furniture, can be found in Wrecks.


Despite their name, Seabases can be built on land. When on land, hull integrity is not a factor, and bases can be built without the need for additional Reinforcements, Foundations, or Bulkheads. Power is still needed for them to operate, but not to provide oxygen.

Hull Integrity

Main article: Hull Integrity

Hull Integrity refers to the ability of the player's Seabase to withstand the pressure of the surrounding water, and as a mechanic slows the expansion of the Seabase. A Seabase starts at 10 integrity, but the majority of the modules will lower the integrity once added with the amount varying 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 a 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 begin flooding with water. Bulkheads can compartmentalize the base and prevent floodwaters from moving between compartments, but if the integrity remains below zero then eventually every compartment will develop a leak and the base will fill with water. To avoid this, quickly increase the base's integrity (by either adding strengthening components or removing weak components) and fix all hull breaches in the base using a Repair Tool.

A Seabase that receives damage to its exterior will also spring leaks, but the hull integrity will be unaffected. This is most likely to occur if the player hits the base with a Cyclops, as aggressive Fauna cannot damage bases. In this case, leaks will be limited to only the module that was hit and will not spread, making Bulkheads an effective method of preventing widespread flooding.

Energy Usage

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 currently four generators available to power Seabases:

Bioreactors and Nuclear Reactors are built inside a Multipurpose Room or Large Room. Solar Panels and Thermal Plants are built outside and can be directly attached to the base or connected via Power Transmitters if the distance is too great.

Seabases do not require energy to operate in Creative Mode.

The following appliances and rooms draw power from the Seabase:

Oxygen

Seabases automatically produce Oxygen as long as there is power supplied, and can be used as a remote oxygen source outside the base through a Base-attached Air Pump and Pipes. 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 piece of seabed or land.
  2. Equip the Habitat Builder and press the appropriate key to bring up a crafting menu.
  3. In the Interior Pieces tab, select the desired module.
  4. Aim at the desired building place (the outline of the module will become green if the location is valid).
  5. Adjust the rotation if desired. You cannot rotate the moonpool once another module has been placed.
  6. Place the module with the correct button.
  7. Once placed, hold the correct key to add the required materials to finish the building process.
  8. Go to Step 2 and repeat for each room you want to build. Remember that once the desired module has been placed, other modules that are placed near it will snap to its position, making it easier to build.

To deconstruct a Seabase module, equip the Habitat Builder and hold the appropriate button while facing the module. If enough inventory space is available, the module will be deconstructed and all materials used to create the module will be returned to the player's inventory, one item at a time. Note that everything inside the module and attached to the outside of the module must be deconstructed (This excludes other Seabase modules, they do not need to be deconstructed to remove a part.) before the module itself can be deconstructed.

Build a habitat


How to obtain: The player has to construct a Seabase module, which requires the Habitat Builder to build.


Trivia

  • Originally when prototyping bases, the developers used square base pieces. This was seen in a developer update along with a screenshot of early base models on the Trello.
  • Several base pieces were cut during development. This includes examples such as the Specimen Analyzer, Power Generator, and Fragment Analyzer.
