Subnautica, an open-world survival adventure video game developed and published by the San Francisco–based studio Unknown Worlds Entertainment. After years of early-access development (a stage in which players can buy and play a game still in progress to provide feedback), it had its full-feature release in 2018, followed by a release for mobile in 2025. Subnautica combines open-world exploration (a game-design model that lets players roam freely in a virtual environment) with survival mechanics such as crafting tools, gathering resources, and managing oxygen, hunger, and thirst levels. Players navigate an alien oceanic planet called 4546B after crash-landing there. The game’s universe expanded with Subnautica: Below Zero (2021), set on 4546B’s ice region, and Subnautica 2, currently in development with an expected release in 2026.
Plot
The Subnautica development team is a small internationally distributed group working across the United States, Australia, France, Thailand, and other countries. At the outset, the team conceived of Subnautica as “a unique experience, the genre of which we [the team] do not believe has yet been invented,” and designed the game to start where most others end. In many role-playing or simulation titles (such as Grand Theft Auto or Oxenfree), water indicates the edge of the playable world; in Subnautica, it is the beginning and the end.
The Earth’s oceans are largely unexplored, so when players descend into Subnautica’s blue depths, the unique challenges they face reflect technical director Max McGuire’s observation: “There’s really nothing more alien on Earth than the ocean.”

The story follows Ryley Robinson, a crew member of the spacecraft Aurora, which crash-lands on the planet 4546B during a mission for the Alterra Corporation. As players explore, they find evidence of the Kharaa bacterium, a fictional biological contagion that wiped out an advanced alien civilization known as the Architects. Swimming through such biomes as bioluminescent reefs, caves, and a forest of mushrooms and several of kelp, players seek a cure for the infection and a way to escape the planet. The narrative unfolds through audio logs, radio transmissions, and atmospheric storytelling.
How to play
Subnautica unfolds entirely through a first-person view, placing the player inside the visor of a lone survivor. With each dive, players must balance gathering the minerals and organics needed to craft protective suits or tools with building underwater shelters that can withstand depth, pressure, and the patience of predators. The game offers four ways to play:
- Survival mode factors in hunger, thirst, and consequences for dying, such as loss of crafted items.
- Freedom mode removes those bodily needs but retains the danger of being preyed upon.
- Hardcore mode gets rid of the safety net altogether, as one death ends the game.
- Creative mode strips away dangers entirely, leaving a sandbox—a game mode without fixed goals, offering freedom to explore, interact with, and modify the environment.
Players build their equipment in the Fabricator, a crafting console found in their lifepods or newly built bases. In the Fabricator, scanned discoveries—that is, objects (minerals or metal fragments) analyzed to unlock their blueprints—become tools, sustenance, and survival gear. Combat exists but feels almost out of place; the game rewards evasion and environmental awareness over aggression. Progress depends on judgment calls; e.g., how far to dive with limited oxygen supply, what to risk for rarer materials, and when to surface. The shifting day-night sequence and unpredictable weather immerse players in their underwater shelters.
Tips and tricks for beginners
The ocean’s bounty: Crafting from the deep
In Subnautica, gathering raw materials is the lifeblood of survival. Early on, the most accessible node is the Limestone Outcrop, which yields either titanium or copper ore. Titanium also comes from metal salvage found on the seabed near the crashed Aurora spaceship. Beyond the hard metals are organic or special-purpose supplies: For example, Creepvine Seed Clusters harvested from Creepvine plants can be used to craft lubricant and silicone rubber, and they power the Bioreactor (a base module that generates energy from organic matter). Another key resource: salt deposits, small white crystals found in various biomes that may be used to craft water and cured food.
Creature feature: Friend or foe?
The depths of planet 4546B are populated by marine monsters. As players drift through the blue, it is only a matter of time before they encounter one of these predators:
- Sea Dragon Leviathan: Found in the lava zones (active and inactive), this behemoth boasts four distinct attacks: bite, hand swipe, meteor, and fire breath, any of which can instantly end escape attempts.
- Ghost Leviathan: Lurking in the Lost River and deeper trenches among other biomes, this creature’s powerful bite or headbutt attack makes a vehicle vulnerable.
- Reaper Leviathan: This species patrols the Crash Zone, Dunes, and Mountains. Its trademark roar is often a signal to steer clear and hide.
- Crabsquid: Found in the Grand Reef and parts of the Blood Kelp Zone, this creature combines powerful claw attacks with an electromagnetic shock that can disable vehicles.
- Ampeel: In the Bulb Zone and Blood Kelp Zone, this serpentlike predator uses both shock attacks and vicious bites.
Not every life-form in Subnautica means harm. The Cuddlefish trails the player like a curious pet, whereas the vast Reefback Leviathan drifts slowly by, carrying living reefs on its back. A Jellyray casts soft light across the darker biomes, and the Titan Holefish helps players replenish oxygen. Even the mischievous Sea Monkey eventually becomes helpful, returning resources instead of stealing them.
Subnautica earned major recognition after its release. At the 2018 Golden Joystick Awards, it won PC Game of the Year, and its creator, Unknown Worlds Entertainment, won the Breakthrough Award. That same year it also took home the Fan Favorite Indie Game prize at the Gamers’ Choice Awards, marking it as one of the most popular independent games of 2018.
Platforms and system requirements
Subnautica runs on multiple platforms. It entered early access on Steam for Windows PC in December 2014, with macOS support in 2015. Console ports arrived in 2018 for PlayStation 4 and Xbox One, and a Nintendo Switch version released in 2021.
