Just one day after Subnautica 2 launched into Early Access on May 14, 2026, Unknown Worlds Entertainment published the game's first official roadmap. The document outlines a clear structure for how the studio plans to develop the game over the coming months and years, covering everything from focused quality-of-life patches to large-scale expansion updates that will add entirely new regions to the ocean world.
Here is a breakdown of everything the roadmap reveals -- from the immediate updates on the horizon to the long-term vision for Subnautica 2.
How the Roadmap Is Structured
Unknown Worlds has organized their Early Access updates into three tiers:
- Improvement Updates -- focused patches that address specific systems, polish existing features, and respond to community feedback.
- Hot Fixes -- rapid patches deployed when critical issues arise.
- Major Expansion Updates -- substantial content drops that add new regions, biomes, creatures, resources, tools, vehicles, and story chapters.
The studio emphasized that improvement updates will serve as the bridge between major expansions. In other words, players should not expect every update to be a massive content drop. Instead, the cadence will alternate between polish-focused patches and the larger world-expanding releases.
Importantly, the roadmap comes with a disclaimer: "This roadmap is subject to change or adjustment." Unknown Worlds made it clear that community feedback will actively shape development priorities.
Update 1.1: Quality of Life
The first major patch, EA 1.1, is labeled as a Quality of Life Update. The entire development team has been working on it since launch, and it targets some of the most commonly discussed systems in the current build.
Planned Improvements
- Biomods System -- adjustments and refinements to how players equip and manage biomods, the game's signature progression mechanic.
- Blight Encounters -- tweaks to the Blight, one of the primary threats players face while exploring wrecks and deeper waters.
- Wrecks Gameplay -- improvements to the experience of exploring and looting underwater wrecks.
- Vehicle Docking and Fabrication -- quality-of-life changes to how vehicles interact with bases and fabrication workflows.
- PDA Databank -- enhancements to the personal digital assistant's data interface.
- Voicelogs Priority System -- a new priority system for managing and playing back voicelogs, which should help players follow the narrative without cluttering their audio feed.
Planned Additions
- More Passive Biomod Slots -- additional passive slots will give players more build flexibility without sacrificing active biomod capacity.
- Storage Cache -- a new storage solution to help manage the growing inventory demands of extended exploration sessions.
- Sprint -- a dedicated sprint mechanic, one of the most-requested features from the community during the opening days of Early Access.
Update 1.1 is the kind of patch that demonstrates Unknown Worlds' commitment to listening. Sprint alone has been one of the most talked-about community requests, and its inclusion signals that the studio is paying close attention to player sentiment.
Update 1.2: Co-Op Centric
The second planned update, EA 1.2, shifts focus squarely to multiplayer and co-op features. Subnautica 2 supports up to four players in online co-op, and Update 1.2 aims to make that shared experience significantly richer.
Planned Improvements
- HUD Signals -- better signal communication between players, so groups can coordinate exploration more effectively.
- Base Builder Tool -- improvements to the cooperative base-building experience, making it easier for multiple players to construct and modify bases together.
- Pinned Recipes System -- a quality-of-life feature that lets players pin crafting recipes for easier reference during multiplayer sessions.
Planned Additions
- Voice Chat -- built-in in-game voice communication, eliminating the need for players to rely on third-party applications.
- Emotes -- non-verbal communication options for underwater interaction.
- Player Trading -- the ability to trade items and resources directly between players.
- Player Revive -- a revive mechanic so downed teammates can be brought back into action without respawning at a base.
- Additional Customizations -- more options for players to personalize their characters and gear.
Voice chat and player revive are standout inclusions here. Currently, co-op players have had to coordinate through external tools like Discord, and the lack of a revive system means that death in co-op can feel particularly punishing. These additions should make the cooperative loop feel much more seamless and enjoyable.
The Major Expansion: A Whole New Region
Beyond the two named updates, the roadmap points toward Future Major Expansion Updates that will fundamentally grow the game. These expansions will introduce an entirely new region to explore, accompanied by:
- New Biomes -- fresh underwater environments with distinct visual identities and ecosystems.
- New Creatures -- additional fauna, likely including new leviathan-class threats.
- New Resources -- materials tied to the new biomes, expanding crafting possibilities.
- New Tools -- equipment designed to help players survive and thrive in the expanded world.
- A New Vehicle -- a brand-new form of underwater transportation.
- Next Chapter of the Story -- the continuation of Subnautica 2's narrative, advancing the plot beyond what is available at launch.
This is where the most transformative content will land. Each major expansion has the potential to reshape the game in the same way that the Lost River and Lava Zone expanded the original Subnautica. Unknown Worlds has not committed to a timeline for the first expansion, but based on the roadmap's structure, players should expect improvement updates to arrive first while the expansion content is developed in parallel.
Timeline Expectations: 2 to 3 Years in Early Access
Unknown Worlds has been transparent about the expected duration of Early Access. On the Steam store page, the studio states:
"Based on previous Early Access games we have developed, we expect it to take about 2 to 3 years."
For context, the original Subnautica spent roughly three years in Early Access (from late 2014 to early 2018) before its full release, and Below Zero followed a similar pattern. A 2-to-3-year window for Subnautica 2 is consistent with that history and suggests the studio plans to deliver substantial content before calling the game complete.
The studio also confirmed that the price will increase after Early Access ends, and that purchasing once during Early Access grants access to all future updates and content at no additional cost.
Ongoing Improvements and Bug Fixes
In addition to the named updates and expansions, Unknown Worlds committed to a continuous stream of ongoing improvements throughout Early Access:
- Bug fixes for crashes, glitches, and progression-blocking issues.
- Balance tuning for combat, creature behavior, resource gathering, and crafting costs.
- Performance optimizations to improve framerates, loading times, and stability.
The game currently holds a "Very Positive" rating on Steam with 94% of roughly 32,000 user reviews being positive, but Early Access players have reported a range of issues including performance drops in dense biomes, occasional save corruption risks, co-op desync, and UI friction. The roadmap's ongoing improvements commitment directly addresses these concerns.
How to Provide Feedback
Unknown Worlds has set up multiple channels for player feedback, and the roadmap explicitly asks the community to use them:
- In-Game Feedback Tool -- a built-in reporting system accessible directly from the game. This is the primary channel for bug reports and technical issues.
- Nolt (subnautica2.nolt.io) -- the official suggestion board where players can submit and upvote feature ideas. The development team actively monitors this board. Top-voted suggestions as of this writing include requests for round rooms in base building, the return of PDA leviathan proximity warnings, wall planters from the original Subnautica, and an alien containment unit for creatures.
- Discord (discord.gg/subnautica) -- the official community server for discussion, bug reporting, and direct interaction with the development team.
- Reddit (r/subnautica) -- the long-standing community hub for Subnautica discussion.
The studio was clear: community input is not just welcome -- it is "key to shaping the game throughout Early Access."
What This Means for Players
The roadmap paints a picture of a disciplined, community-driven development process. Update 1.1 addresses the rough edges of the launch build. Update 1.2 strengthens the co-op experience that many players bought the game for. And the major expansions promise the kind of world-expanding content that made the original Subnautica a genre-defining experience.
For players still on the fence about diving into Early Access, the key takeaway is straightforward: the game is actively being shaped by its community, the first two updates target the most pressing pain points, and all future content is included with the current $29.99 purchase price before it inevitably goes up at full release.
The depths are calling. Keep diving.
