General Information

Title(s): Subnautica
Publisher: Unknown Worlds Entertainment
Description: Subnautica begins with the crash of the Aurora on Planet 4546B, a planet completely covered in water, in the late 22nd century. There is one sole longterm survivor, who is the protagonist of the story. It is then up to the player to make it through the initial days with a partially broken Lifepod 5 and a few resources at their disposal, improve their situation by learning about the alien environment and gathering resources, building better equipment, and maybe even find a way home. If so chosen, the player can also start an investigation into what happened to the Aurora and what secrets Planet 4546B holds.
Similar Games: Biosys, Submerged, and Ark: Survival Evolved. Beyond Good & Evil is partially the inspiration to the scanner and the camera function of the PDA.[1]
Genre(s): The game puts together survival and exploration elements. To quote Wikipedia, survival games "are a subgenre of action video games that generally start the player with minimal resources in a hostile, open-world environment, and require them to collect resources, craft tools, weapons, and shelter, and survive as long as possible", whereas exploration games "are narrative-focused [adventure games] that allow players to experience their story through exploration and discovery".
Playthrough Length: Subnautica offers a static world of 3*3*1.7km and random generation is exclusively present in the spawn points of various resources and the exact starting position of Lifepod 5. There is no multiplayer, and there never will be.[2] If the player knows where to go and rushes through the essential parts of the story and useful blueprints, the game can be completed in 20 hours. Players that go for the full experience will find themselves at 40+ hours.
Difficulty: There are four game modes available: Creative, Freedom, Survival, and Hardcore. Creative mode makes no demands on the player at all. Freedom mode requires managing oxygen, health, energy, and hull integrity. Upon death, the player respawns in Lifepod 5 or in the last Seabase/Cyclops visited. Survival mode adds hunger and thirst. Hardcore is identical to Survival except that it features permadeath.

Although combat is an option, it is generally the lesser pick compared to stealth and speed.[3] All but the largest creatures can be evaded or outrun with a little practice. The game does not have intentional jumpscares, but a few creatures such as Warpers and Crabsnakes can cause them. Exploring maze-like structures such as caves and wrecks demands navigational skill and proper preparation to not run out of oxygen. Hunger and thirst are a core concern early on and it might take a while before steady solutions are acquired.
Security Concerns: Being a singleplayer-only game, Subnautica has no security risks.

Content Information

Violence: Subnautica does contain very few conventional weapons and the few there are have limitations. This is because the game tries to promote solutions other than violence.[3] One can still kill or be killed by wildlife or die from environmental hazards such as radiation and lava geysers. In case damage is sustained, the protagonist lets out a muffled scream, the sides of the screen flash red, and a small amount of red blood is lost. Death due to lack of oxygen begins with a darkening screen followed by a dramatic tune if an oxygen source isn't reached after a few more seconds. Creatures that are killed currently bleed yellow and either respawn or revive some time after the player leaves their territory. The backstory of Subnautica contains the deaths of about 170 people and an unknown number of other sapient lifeforms. Data Downloads and materials left by them can be found, but there are no corpses.
Language: The word "Damn" is said a few times in some of the Degasi Survivor's PDAs, as well as "what the hell" in a lifepod transmission.
Sexual Themes and Nudity: There are no sexual themes or nudity.
Drugs and Alcohol: A few bottles that appear to have held alcohol are lying on the floors of the Aurora and within the Deep Grand Reef Degasi Base. These cannot be interacted with and are for decoration only.
Crude Humor or Comic Mischief: The Stillsuit reclaims bodily fluids and cleans it for consumption. The databank entry includes such lines as "Because drinking reclaimed urine is better than death by dehydration." A resource to collect is Alien Feces.

FOX 3D Entertainment - Company Specializing in 3D models

Fox3D has successfully cooperated with game developers of all sizes and world-class publishers from North America, Europe and Asia. Our aim is to create high-quality projects on a global scale.

It is brilliant sample of high quality cinematic needs for our Subnautica. Fox3D made it with tight budget and deadlines with great quality!

—Cory Strader, Art Director of Unknown Worlds

Sergey Solovyev - Lead Artist

Hi, my name is Sergey Solovyev. At the very beginning on the Subnautica, I was faced with a task - to build our Fox3D team into an effective working art resource for the project. Although the team members never gathered under one office roof, my goal was to make them work as well as normal game developer teams.

After a number of approaches and brainstorming sessions, we understood that for such a big project as ours, we needed the highest possible visualization of workflow and the creation of one general work space in order for efficient remote working. This meant creating something like a virtual office that copies the functionality of a real physical office. We built work processes in such a way that a person from anywhere on the globe, who has a laptop and an Internet connection, could easily learn about the development stage of any asset, find out what was updated, and if necessary, send comments about what else should be done. Such an approach demanded decision making about a remote working field, which is why we spent such a long time searching for the new services that would be as easy and convenient as possible.

In this case, Sketchfab was very suitable for us. There is nothing better than giving an art director the possibility to spin around, on his laptop screen, a finished 3D model of a monster, spaceship or main character of the game. Whether in a cafe, house, or in the office, his work is equally effective - he can see an exact model, the same way as it will look in game, and immediately give us feedback about it. And since Sketchfab supports normal maps, spec, gloss and hdri lighting, it was completely suitable for us and the Subnautica project. All of these features are important for the project.

We enjoy working on Subnautica, and like the idea of creating a colourful, cartoon style underwater world. It is so exciting to participate in creation of such a tremendous and unusual world from an art-concept to the game. We are inspired by how unusual and scenic the locations and creatures look. It’s probably a little immodest to say, but I think I have to say it: as I see it, Subnautica is the first fully underwater game, and it actually looks great! And it wouldn’t have happened without such a great community. The feedback we receive inspires our artists and pushes them to do the artwork better and better each time.

I would like to thank all those wonderful people who are supporting us with attention to our artwork. It is always thrilling to log in Sketchfab and find new likes, comments, and a growing number of followers.

Thanks people, you rock! Many thanks to the Sketchfab team for making all these magnificent opportunities become real tools. See you in Subnautica, divers!

Subnautica merchandise can be purchased at the official UnknownWorlds merchandise redbubble store.


Subnautica was originally released on PC, Mac, PS4 and Xbox One in 2018.[4] Versions for the Nintendo Switch, PS5, and Xbox Series X/S were released in May 2021 alongside the release of Subnautica: Below Zero.

As of October 2021, Unknown Worlds is working on technical improvements on the code base of the Subnautica series, such as retooling the save system, and merging the code base of the games across all availabe platforms to unified versions of Unity. Subnautica is to be updated with architecture, performance improvements, and bug fixes from Below Zero. Save bugs on PS5 are to addressed, as is excessive screen tearing on the PS5 version of Subnautica.

There are also plans to update Subnautica over time with a number of quality of life features/accessibility improvements that make sense for the game from the ones that were developed and implemented for Below Zero.[5]


On Metacritic, Subnautica received "generally favorable" reviews getting a metascore of 87/100 on PC,[6] 80/100 on PS4,[7] and 81/100 on Xbox One.[8]

Ian Birnbaum of PC Gamer described Subnautica as an "underwater Minecraft", remarking that "with an experienced developer at the helm and a limitless variety of the oceans to play with, it’s going to take a lot for Subnautica to go badly wrong. As the toolbox gets deeper and the shape of the end-game gets set, Subnautica will be a unique example of the ways survival can be tense, rewarding, and fun." Marsh Davies of Rock, Paper, Shotgun praised the rewarding nature of exploring the world of Subnautica, but criticized the "arbitrariness" and lack of intuition in some of the in-game recipes.

Subnautica is heavily praised by many Youtubers for being very original.

T.J Hafer from IGN gave the game a 9.1/10. Commenting that Subnautica was one of the few games he would love to wipe from his past and start over fresh. Claiming the game to be "legitimately terrifying", similar to when playing horror games such as Amnesia or Outlast. Praising the uniqueness of the biomes, as their visual identities and soundtracks helped solidify their uniqueness. He also gave praise to the audio, claiming it helped him in identifying which biome he was in and what creature he was dealing with.

Hafer heavily gave praise to the Story, explaining that Subnautica does a very good job at telling a compelling story, noting the complexity and nuance of a great sci-fi film. He also complimented the well-written journal entries and audio logs with uncommonly high-quality voice acting. T.J commended the fact that the story was not a forced element, and players could explore and progress at their own pace.

Hafer criticized that sometimes the progression dragged at spots. He furthermore gave notice to when his immersion was disrupted by pop-in and jarring levels of detail changes. claiming he would have loved more options to help smooth it out.

Overall, T.J came to the verdict that Subnautica is a template for what open-world survival games should strive to be, as the game was fantastical, fresh, and frightening. [1]


Various users of the game have produced modifications for the game. None of them are endorsed by Unknown Worlds Entertainment or this wiki and are not guaranteed to be high-quality, functional, or safe. There is, however, a Discord for mods, where players can discuss mods.

  • Nitrox, a mod that enables multiplayer.
