Cut Content (Subnautica)

This page serves to chronicle any significant content that has been removed from Subnautica.

Accumulator
The Accumulator was a machine meant to store power for Seabases. It is unknown why it was cut.

Spawn: spawn/item accumulator

Amino Acid


Amino Acid was an unimplemented raw material. It was used to create Graphene.

Spawn: item aminoacid

Basalt Outcrop
Basalt Outcrops were a common outcrop type that spawned in many biomes, they dropped Gold, Diamond, and previously, Uraninite Crystals. They received a final model and why they were removed is not full known. Basalt Outcrops spawned in the following biomes:
 * Blood Kelp Caves
 * Blood Kelp Zone
 * Bulb Zone
 * Bulb Zone Caves
 * Crag Field
 * Deep Grand Reef
 * Grand Reef
 * Lava Geyser
 * Mountain Island
 * Mountain Range Caves
 * Mushroom Forest
 * Sea Treader's Path
 * Sea Treader's Tunnel Caves
 * Underwater Islands

Botanical Analysis Machine
The Botanical Analysis Machine was a machine meant to study Flora, it was cut when the Scanner was added.

Current Generator


The Current Generator was a deployable crafted using the Fabricator. The Current Generator took up four slots in the player's Inventory, that meant the player could carry 12 of them if their inventory was cleared first. The Current Generator used no power and could be left on all the time.

Once the device was deployed and activated, it would produce a column-shaped hydro-current from an emitter on its front. This stream could push small and large objects alike, including Lifepod 5 and the Reefback. However the Seamoth and Cyclops were not affected by the Current Generator.

The Current Generator has been scrapped and is no longer available in the game.

Fragment Analyzer


The Fragment Analyzer was a Placeable Item that was used to decode Fragments into Blueprints. Only one fragment was needed to research a blueprint however the Fragment Analyzer could research four fragments at a time. The progress of analysis was displayed when the player looked at the Fragment Analyzer. At one point a Fragment Analyzer was pre-installed inside the Lifepod. The functionality of the Fragment Analyzer was given to the Scanner and the fragment system was reworked.

Spawn: spawn fragmentanalyzer (Does not work, only works as storage)

Graphene


Graphene was a material that was crafted at the Fabricator.

Spawn: item/spawn graphene

Hardened Blade
The Hardened Blade was an upgraded version of the Survival Knife. It was crafted with the Modification Station. It did more damage than the Survival Knife but less than the Thermoblade. Before durability was removed it had double the durability than the Survival Knife. It was removed since it was deemed worthless when durability was removed. Spawn: item diamondblade

Lithium Ion Battery


The Lithium Ion Battery was an upgrade to the Battery that was crafted at the Modification Station. The Lithium Ion Battery held twice as much energy as the Battery. The Lithium Ion Battery can now only be crafted in Creative Mode. A new battery, the Ion Battery, uses an Ion Cube instead of Lithium.

Spawn: item lithiumionbattery

Nanowires


Nanowires were a nano-scale Electronic item crafted from Mercury Ore that was intended for quantum devices and sensors.

Spawn: item nanowires

Magnesium
Magnesium was a material crafted using three Salt Deposits in the Fabricator. Magnesium was only used in one crafting recipe, that of the Repair Tool. As it was only used in one recipe it was seen as useless and was removed, being replaced by Salt in its sole crafting recipe.

Spawn: magnesium

Obsidian Outcrop
Obsidian Outcrops were Harvesting Nodes found in the Lava Zones, they dropped only Diamond and never received a final model. They spawned in the following biomes:
 * Inactive Lava Zone
 * Inactive Lava Zone Corridor
 * Lava Castle
 * Lava Lakes

Old Observatory


The Old Observatory was a small primitive glass box that could be constructed with the Mobile Vehicle Bay. Unlike the newer Observatory it was not a Seabase module and was instead freestanding. It had two entrances and was primarily used to observe Fauna and the environment. The only way to move it was to use Floaters.

Old Bioreactor


The old Bioreactor was built outside of a base and could only be powered using Fungal Samples and Creepvine Samples.

Old Nuclear Reactor
The old Nuclear Reactor was built outside of the Seabase and had to be supplied with raw Uranium to function.

Power Generator


The Power Generator was a Placeable Item that generated Power for Seabases using Power Cells. The Power Generator had a capacity. In the starting of Subnautica it was the only method to give energy to Seabases, and it didn't need any kind of item to generate the energy.

Powerglide


The Powerglide was an upgrade for the Seaglide, it was 3x the speed of the Seaglide and had a turbo boost that drastically increased the speed of the Powerglide. The Powerglide's model was identical to that of the Seaglide's.

Spawn: item powerglide (no longer available)

Terraformer


The Terraformer was a tool that allowed the player to remove material from one place in the world and deposit it somewhere else. A counter showed the current amount of material held by the device.

Terraformer's Removal from game
The Terraformer was removed due to performance issues because of the way the Terraformer works. The Terraformer model may later be used for an unknown purpose in later updates, as the developers thought the model was "too cool".

Spawn: item terraformer

Thermometer
The Thermometer was a piece of equipment that allowed the player to see the temperature at their current location. It was removed because it was rarely used during gameplay, rendering it useless. The appearance of temperature was moved to vehicle HUDs instead.

Specimen Analyzer


The Specimen Analyzer was a machine meant to study Eggs. It was removed when the Alien Containment and Scanner were added.

Spawn: spawn specimenanalyzer (does not work and only holds small eggs)

Uranium
Uranium was an item belonging to the Advanced Materials category that was removed in the Prison Update. It was crafted using three Uraninite Crystals, and was used in the crafting of Reactor Rods and several Electronic items. Uranium was removed to simplify the Reactor Rod recipe.

Shell Hull Reinforcement Module


The Shell Hull Reinforcement Module was an Upgrade Module for the Cyclops. When used to upgrade the Cyclops, it added 1600 meters to both the safe depth and the crush depth. This item was removed when the new, non-stacking upgrade system was introduced.

Chelonian Hull Reinforcement Module


The Chelonian Hull Reinforcement Module was an Upgrade Module for the Cyclops. When used to upgrade the Cyclops, it added 2800 meters to both the safe depth and the crush depth. The Chelonian Hull Reinforcement Module was the strongest reinforcement module. To create the module, blueprints from the Specimen Analyzer were required as Reefback DNA was part of the recipe. This item was removed when the new, non-stacking upgrade system was introduced.

Entity Gallery
The entity gallery was a series of textureless, white boxes that could be spawned by typing "entgal" into the console. On top of each box an entity from the world of Subnautica could be found. Of the various things found here, the model of the scrapped "Sandworm" creature was perhaps the most notable.

The entity gallery's removal may have been due to the multiple occasions in which Precursor objects were mistakenly added to the gallery; This resulted in Precursor objects and bases being revealed to the public long before they were intended to be. The most well known example of this was the "Rainbow Update" in which many of the games textures were converted to multicoloured squares, this was because the game had gone over the limit of textures by the accidental addition of a work-in-progress Quarantine Enforcement Platform model and several other Precursor props to the gallery.
