Subnautica is widely praised for its immersive underwater survival experience, leaving many players wondering whether they can explore the alien ocean alongside friends. The short answer is that Subnautica is not officially multiplayer. It is designed as a single-player experience focused on isolation, exploration, and survival. However, there are mods and workarounds that introduce limited cooperative play on PC, though these are not officially supported.
TLDR: Subnautica is primarily a single-player survival game with no official multiplayer mode. The developers designed it around isolation and storytelling, which are central to the experience. While modders have created unofficial multiplayer options for PC, these come with limitations and potential technical issues. Console players do not have access to multiplayer features.
Understanding Subnautica’s Core Design
Subnautica, developed by Unknown Worlds Entertainment, launched in full in 2018 after an early access period. From the beginning, it was conceived as a single-player survival adventure set on the alien ocean planet 4546B. Players crash-land on the planet and must gather resources, craft equipment, build underwater bases, and uncover the mysteries of the environment — all while surviving against hostile creatures and environmental hazards.
The feeling of isolation is not accidental; it is a core pillar of the game’s design philosophy. The developers intentionally crafted an atmosphere of solitude to heighten emotional impact, tension, and immersion. Being alone in a vast, seemingly endless ocean enhances both the fear and beauty of discovery.
This design choice naturally raises the question: Would adding another player change that atmosphere?
Is There Official Multiplayer Support?
In its standard, base format, Subnautica does not feature multiplayer. There is:
- No online co-op mode
- No split-screen multiplayer
- No LAN play
- No cross-platform multiplayer support
The game supports single-player only across all official platforms:
- PC (Windows and macOS)
- PlayStation
- Xbox
- Nintendo Switch
The sequel, Subnautica: Below Zero, also maintains this single-player structure.
Unknown Worlds has stated in various interviews and community discussions that multiplayer was experimented with early in development. However, maintaining technical stability and preserving artistic vision proved difficult. The added complexity shifted focus away from the solitary survival experience they wanted to perfect.
Why Subnautica Works as a Single-Player Game
To fully appreciate why multiplayer is absent, it’s important to understand how the game builds its emotional resonance.
Atmosphere and Tension: The deep ocean is intimidating. Sounds echo through dark waters, and distant creatures roar somewhere beyond visibility. Being alone intensifies this tension. If a friend were beside the player cracking jokes, the fear factor might significantly diminish.
Storytelling: Much of Subnautica’s narrative unfolds through environmental storytelling and voice logs. These moments often feel personal — almost intimate. A solo experience allows players to absorb the story at their own pace.
Exploration Freedom: In multiplayer survival games, players often divide tasks and progress more quickly. Subnautica is carefully balanced around solo progression curves, ensuring challenges feel meaningful rather than rushed.
While some players argue that cooperative survival would enhance replayability, others believe it would compromise what makes the game special in the first place.
Unofficial Multiplayer Mods
Although there is no official multiplayer mode, PC players have access to unofficial multiplayer mods. The most well-known of these is the Nitrox Mod.
What is Nitrox?
Nitrox is a fan-made modification that enables cooperative multiplayer for Subnautica on PC. It allows multiple players to connect to a shared world and explore together.
Key Features of Multiplayer Mods
- Shared base building
- Joint exploration
- Cooperative resource gathering
- Synchronized vehicle usage (with limitations)
However, these mods are not without drawbacks:
- Potential bugs and crashes
- Desynchronization issues
- Limited compatibility with new game updates
- No official customer support
Because the game was not originally engineered for multiplayer, modders had to work around core systems. As a result, performance and stability can vary significantly depending on hardware and configuration.
Important: Multiplayer mods are only available for the PC version. Console players have no way to install or use these modifications.
How Multiplayer Changes the Experience
If players install and successfully run a multiplayer mod, the gameplay dynamic shifts noticeably.

Faster Progression: Tasks such as gathering rare materials, crafting advanced equipment, and constructing large bases become easier and quicker.
Shared Creativity: Designing elaborate underwater habitats becomes a collaborative project rather than a solitary one.
While these elements can make the game more social and entertaining, some players feel they undercut the emotional weight of solitude that defines the classic experience.
Community Demand for Multiplayer
Over the years, community forums and social media platforms have frequently lit up with discussions about official multiplayer.
Common player arguments in favor of multiplayer include:
- Increased replay value
- Shared exploration with friends
- Cooperative survival challenge
On the other hand, some players defend the single-player format as essential.
The developers have historically indicated that adding full multiplayer would require substantial redesign of core systems. In many cases, online functionality must be planned from the ground up. Retrofitting it into an existing single-player survival sandbox can introduce major technical challenges.
Comparisons to Other Survival Games
In the broader survival genre, multiplayer is common. Games like ARK: Survival Evolved, Rust, and Minecraft offer cooperative and competitive options.
However, Subnautica differs in significant ways:
- Stronger narrative emphasis
- Heavier atmospheric storytelling
- No PvP mechanics
- Carefully balanced solo resource economy
Rather than being a sandbox meant primarily for player interaction, Subnautica plays more like a narrative-driven survival adventure in an open environment.

The question remains open regarding future entries in the franchise. Unknown Worlds has hinted at expanding the Subnautica universe, and speculative discussions about cooperative play continue within the community.
Developers have not definitively ruled out multiplayer in future installments. However, they have consistently emphasized maintaining atmosphere and immersion as guiding principles.
If multiplayer were ever introduced officially, it would likely be:
- Carefully integrated from the beginning
- Designed to preserve tension and pacing
- Possibly limited to small co-op groups
Until such an announcement is made, players should assume Subnautica will remain a primarily solo experience.
Final Verdict
So, is Subnautica multiplayer?
No — not officially.
The game was intentionally designed as a single-player survival journey focused on solitude, atmosphere, and self-reliance. While PC players can experiment with unofficial mods to add cooperative play, these solutions are neither supported nor perfect.
For many fans, the absence of multiplayer is not a flaw but a feature. The isolation enhances emotional impact and immersion, making every discovery, danger, and triumph feel personal.
Whether exploring alone in a Seamoth or cautiously venturing into darker depths, Subnautica remains one of the most compelling single-player survival experiences available today.
