Many players assume Subnautica 3 will simply be more of the same: dive, gather, build, and escape. That assumption misses the point. The next entry in the series is being built from the ground up, with a new engine and a new studio structure, and it may not even be called Subnautica 3 when it ships.
How the Original Subnautica Shaped the Sequel’s Design Philosophy
The first Subnautica launched in early access in 2014 and fully released in 2018. It replaced the genre’s typical gunplay with a focus on alien ocean exploration and a quiet sense of dread. Unknown Worlds Entertainment, the studio behind it, built the game in Unity, and that engine choice defined the game’s visual style and performance limits.
Subnautica: Below Zero followed in 2021, but it was originally planned as an expansion. That project taught the developers a hard lesson: scope creep and community feedback can pull a project in conflicting directions. For the next game, the team has said they want to return to the “magic” of the first game’s unknown, rather than the more guided narrative of Below Zero.
That history matters because it explains why the next game is taking so long. Unknown Worlds is not just iterating; they are rebuilding. The move also means the game will not be a simple asset flip of previous titles.
One of the most telling details comes from a 2023 job posting. Unknown Worlds was hiring for a “narrative director” with experience in “open-world survival” games. That role did not exist during the development of the first two games, suggesting the next title will place a heavier emphasis on story and character.
Who Wins and Who Loses If Subnautica 3 Goes Multiplayer
The biggest unresolved question is whether the next game will include multiplayer. The original Subnautica was strictly single-player, and that isolation was a core part of its horror. Below Zero added a voice-acted protagonist but kept the solo experience. A multiplayer mode would change the emotional tone entirely.

For solo players, the loss of isolation could be a dealbreaker. The fear of the deep is amplified when you are alone. Co-op play, even optional, often leads developers to balance encounters for groups, which can dilute the tension. On the other hand, a shared world could attract a broader audience, especially those who found the loneliness off-putting.
In a 2023 interview, the studio’s creative director said they are “exploring ways to share the experience” without specifying what that means. That vague phrasing has fueled speculation, but it also signals that the team is aware of the trade-off.
For the studio itself, the stakes are financial. Unknown Worlds is now owned by Krafton, the South Korean publisher behind PUBG. Krafton has pushed for live-service elements in its other titles, and some fans worry that pressure could lead to microtransactions or always-online requirements. So far, no such features have been announced, but the corporate parent’s influence is a real concern for long-time players.
What Is Confirmed and What Remains Unverified About the Next Game
Let’s separate fact from rumor. That last one is the strongest evidence yet that co-op or online play is on the table. wikipedia.org/wiki/Subnautica” rel=”noopener noreferrer” target=”_blank”>Subnautica
Unconfirmed: the game’s title. The studio has referred to it internally as “Subnautica 3,” but they have also said the final name may change. Unconfirmed: a release date. The most optimistic estimates point to 2025, but given the engine switch and the studio’s history of delays, 2026 is more realistic.
Rumors about the setting are also swirling. Some fans point to a 2022 concept art leak that shows a frozen planet with massive ice structures. Others argue the next game will return to the original planet, 4546B, but at a different time period.
One thing is certain: the game will not be a direct sequel to Below Zero. The studio has said the next title will be a “new experience” that stands on its own, even if it shares the Subnautica name. That means players should not expect to revisit the same characters or locations.
From Mod to Mainstream: The Studio’s Origin Story
Unknown Worlds started as a small indie team in 2009, founded by Charlie Cleveland. The studio’s first game was Natural Selection 2, a hybrid of real-time strategy and first-person shooter. That project taught the team about community-driven development, a lesson they carried into Subnautica.
The idea for Subnautica came from a game jam in 2013. Cleveland and a few colleagues wanted to explore the fear of the unknown, and they chose the ocean as the setting because it is both beautiful and terrifying. The prototype was built in a few weeks, and the positive reaction convinced them to pursue it full-time.
Subnautica’s development was not smooth. The team had to build an entire underwater ecosystem from scratch, including a day-night cycle, weather systems, and creatures that reacted to the player. They also had to solve the problem of motion sickness, which is common in underwater games. Their solution was a combination of smooth camera movements and a clear sense of verticality.
By the time Subnautica left early access in 2018, it had sold millions of copies and won multiple awards, including a BAFTA for Best Original Property. That success attracted Krafton, which acquired Unknown Worlds in 2020. The acquisition gave the studio more resources but also introduced corporate oversight, a trade-off that many indie fans view with suspicion.
Now, with a larger team and a bigger budget, Unknown Worlds is attempting its most ambitious project yet. The studio has grown from a handful of developers to over 60 people, and they are using that scale to build a game that can compete with the biggest survival titles on the market.
Frequently Asked Questions
How will Subnautica 3 differ from the previous games?
Moving to Unreal Engine 5 allows for more realistic water physics and larger draw distances.
