Cut Content (Subnautica)

This page serves to chronicle any significant content that was cut from the final version of Subnautica.

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

Spawn: spawn/item accumulator

Sand
Before terraforming was removed, you could dig Sand in the environment. It would be used to create Glass.

Acid Mushroom Shrinking
In early builds Acid Mushrooms would retract when approached. Now only Deep Shrooms have this effect.

Amino Acid


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

Spawn: item aminoacids

Carbon
Carbon was made from three Acid Mushrooms and was primarily used to craft Batteries.

Zinc
In early builds, Zinc could be obtained from Limestone Outcrops.

Basalt Outcrop
Basalt Outcrops were a common outcrop type that spawned in many biomes, and looked very similar to the Shale Outcrop. They dropped Gold, Diamond, and Uraninite Crystals. They received a final model and why they were removed is not fully known. Basalt Outcrops spawned in the following biomes: Spawn: basaltchunk (now only drops Nickel, Lithium, and rarely Diamonds).
 * 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

Bloom Plankton
Bloom Plankton are a small fauna species that were never implemented in the game, but can be spawned with "spawn bloom". Bloom Plankton is found only in groups and usually invisible, only becoming visible when they are "charged" with light. Their colour can be altered by shining different types of light onto them. Shining a Flashlight into a group of Bloom Plankton will cause them to glow bright white in colour; if a flare is thrown near a group of Bloom Plankton they will glow red in color, this color will be retained for a few moments before they become invisible again.

When charged, they can become a light source and will light up their surroundings. This could be used to the Player's advantage to navigate in dark areas. When charged with light, Bloom Plankton will constantly shift and move amongst each other. Bloom Plankton will swarm around light sources and stay there, it is unknown if this interaction with light benefits them.

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. This is possibly because it would have created lag and/or loading problems.

Calcium
Calcium was a craftable resource that was used in the production of bleach and was made from Coral Tube Samples. It has now been replaced by Salt Deposits in the recipe for bleach.

Drill
The Drill was planned to be an item in Subnautica. Little is known about the drill and it was scrapped in early development. However its main purpose would probably have been drilling outcrops or drilling in the ground. it's texture has been removed and does not work.

Spawn : item drill

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. Its damage output is 30 health. Before durability was removed, it had double the durability of the Survival Knife. It was removed since it was deemed worthless when durability was removed. Despite being removed, it is still mentioned in the "Degasi Voice Log #8 - Risk Taking." 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

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: item magnesium

Mercury Ore
Mercury Ore was a material found in various biomes and was originally used in the Cyclops Fire Suppression System before being replaced by Crystalline Sulfur. It then remained in game until the full release, when it was finally cut.

Spawn: item mercuryore

Nanowires


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

Spawn: item nanowires

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

Spawn: spawn obsidianchunk

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 Uraninite 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. It was only a temporary power source, and was removed when it was essentially replaced by the Nuclear Reactor and Reactor Rods.

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 its speed. The Powerglide's model was identical to that of the Seaglide's. It was cut early in development due to the player glitching into the ground.

Sand Worm
The Sand Worm was a scrapped creature. Although unfinished, the intention of this creature was to have it burrow into a hole similar to that of a Tree Leech, and surprise the player, or any fauna that came near it in a similar fashion to the Reaper Leviathan and Crabsnake attacks.

Terraformer


The Terraformer was a tool that allowed the player to remove material from one place in the world and deposit it elsewhere. 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". If the Terraformer is spawned in more current versions, the description is "RIP terraformer" referring to the development team's disappointment in having to remove it. The item texture in the inventory has also been deleted and changed to the ? icon. Although it is still functional when spawned in, all changes made to the terrain using the Terraformer will be reset upon reloading the world.

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 hard to implement into the latest HUD, and was rarely used during gameplay, which rendered it not worth keeping. It's removal was made more apparent by the addition of built in thermometers on vehicle HUDs (Seamoth, Prawn Suit , and Cyclops).

Despite being removed the blueprint can still be found in the PDA.

Spawn : item thermometer (does not appear in inventory)

Transfuser
The Transfuser was a Tool intended to sample DNA from life forms and then use this DNA in the Centrifuge to create consumable items that would alter the player's or other creatures' attributes. The model was reused for Subnautica: Below Zero's Bioscanner. You can still find it in the creative blueprints.

The transfuser's description was changed to: congrats translators, we made a game!

Spawn : item transfuser

Centrifuge
The Centrifuge was meant to be used to turn DNA samples collected using the Transfuser into four transfuser serums.

Spawn : spawn centrifuge

Specimen Analyzer


The Specimen Analyzer was a machine meant to study Eggs. It was removed when the Alien Containment and Scanner were added. Despite being removed, you can still see it's model in Below zero's Research Base Zero.

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 Voice of the Deep 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.

Spawn : item uranium

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.

Spawn : item 1514 (still works, contains no icon)

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, along with the removal of DNA samples.

Spawn : item 1515 (still works, contains no icon)

Cyclops Pressure Compensator


The Cyclops Pressure Compensator was an Upgrade Module for the Cyclops. When put into the Cyclops upgrade panel, it added 900 meters to both the the safe and crush depth.

Spawn : item 1501 (still works, contains no icon)

Unused Alien Data Terminal Variant
An unused version of the Alien Data Terminal, albeit a more cyan hue. Where this would have been located is unknown, although it can be assumed that it would have functioned identically to the Orange and Green Terminals.

Unused Alien Tablets
There are currently two unused Alien Tablets that were going to be used for unknown things (Possibly to deactivate Forcefields or other unimplemented features).

Red Tablet


The Red Tablet or Red Precursor Key is an unused Alien Tablet that was going to presumably deactivate forcefields.

Spawn : item precursorkey_red

White Tablet
The White Tablet or White Precursor Key is an unused Alien Tablet that was previously intended to unlock the Alien Thermal Plant. The white tablet was a 4 (2x2) slot item, rather than a 1 slot item like all the other keys. If one summons precursor keys in the developer menu, they will get a White Tablet and a Red Tablet. Spawn : item precursorkey_white

Ion Cube Matrix
An Ion Cube Matrix is a piece of technology that was originally planned to be used in the construction of the Neptune Escape Rocket. However, it was replaced with Ion Power Cells.

An Ion Cube Matrix would be crafted with five Ion Cubes.

Spawn : item precursorioncrystalmatrix

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 models of the scrapped "Sandworm" and "Grab Crab" creatures were 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 "Skittles 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 the Quarantine Enforcement Platform model and several other Precursor props to the gallery.
