Subnautica 2 EA 1.1 Update: Patch Notes & New Features
Subnautica 2 update EA 1.1 is the first quality-of-life patch on the Early Access roadmap, focused on biomods, Blight encounters, wreck gameplay, vehicle docking, PDA upgrades, Sprint, and storage. Unknown Worlds has not confirmed a release date yet.
Last updated: September 5, 2026
What Is EA 1.1?
EA 1.1 is the first major update on the published Early Access roadmap. Where the EA 1.2 update targets co-op features, EA 1.1 is a quality-of-life pass: it improves systems that already exist rather than adding new regions or story chapters. The bigger content drops â new biomes, creatures, resources, and the large multi-seat submarine â are reserved for later major expansions.
Since the game launched into Early Access on May 14, 2026, this is the update most players have been waiting on, and it touches almost every part of the core loop: character progression, exploration, vehicles, and base logistics.
Full EA 1.1 Feature List
Everything confirmed for the update, grouped by system:
| Feature | Category | What It Does |
|---|---|---|
| Biomods improvements + more passive slots | Progression | An overhaul of the biomods system, plus additional passive biomod slots for deeper character builds. See our Biomods Guide. |
| Expanded Blight encounters | Hazard | The Blight becomes a bigger presence, with more encounter variety across Proteus. |
| Enhanced wreck gameplay | Exploration | Upgrades to the wreck exploration loop â the core source of fragments and Portable Lockers. |
| Vehicle docking & fabrication upgrades | Vehicles | Improvements to docking (which currently recharges the Tadpole) and vehicle fabrication workflows. |
| PDA Databank expansion | UI / Lore | A larger PDA Databank for entries, blueprints, and collected data. |
| Priority voice log system | UI / Story | Important voice logs get priority treatment so critical story audio doesn't get buried. |
| Sprint ability | Movement | A dedicated Sprint ability for faster traversal. |
| Storage cache system | Base / QoL | A new storage cache system to ease inventory and base-logistics pressure. |
What EA 1.1 Means for Players
Character Builds Get Deeper
More passive biomod slots means fewer painful choices between Adaptations. Start thinking about your loadout now with our Biomods Guide.
Vehicles Feel Better
Docking and fabrication upgrades should smooth out the Tadpole ownership loop â charging, upgrading chassis modules, and parking at outposts.
Exploration Gets More Dangerous
Expanded Blight encounters mean deeper runs need more preparation: health items for poison spores, spare batteries, and escape routes memorized.
Hoarding Gets Easier
The storage cache system relieves the constant locker Tetris of the launch build â good news for miners hauling bulk Titanium and Quartz.
If you want to hit the ground running when EA 1.1 lands, make sure your base already has power, a Base Fabricator, and a Scanner Station. Our Base Building Guide and Beginner Tips cover the optimal early setup.
Release Date Status
There is no confirmed release date for EA 1.1. It sits first on the roadmap, ahead of the co-op-focused EA 1.2, but Unknown Worlds has not committed to a date for either. Early Access overall is expected to last 2â3 years, with the full 1.0 release bringing a price increase â so the current Early Access price is the cheapest the game will be.
The story itself is delivered in chapters â one chapter shipped at Early Access launch, with 10 planned for the full 1.0 release â so expect story chapters to arrive alongside system updates like this one over the course of Early Access.
We update this page the moment official patch notes drop. All Early Access updates are free â Subnautica 2 has no microtransactions, battle passes, or season passes.
