Subnautica 2 Patch Notes: Fixes by Player Problem

October 6, 2026 — Buddy System Hotfix 2

Read the complete official note. This is the latest maintenance release reviewed on October 18.

• Resource scanning: corrected Scanner Station accuracy. If a search result or old clip describes phantom or missing resources, compare its build before repeating a workaround.
• Overgrown Ruins: corrected currents and missing names on previously unlocked Blackbox signals after loading a save.
• Vehicles and power: addressed out-of-bounds Tadpole recovery, docking conditions, and generator power after streaming out and back in.
• Creature interaction: changed Shiver interaction with unpiloted vehicles and improved the Tadpole Leviathan grab attack.

These are scoped fixes, not proof that every related issue is solved in every save.

September 1, 2026 — Buddy System Hotfix 1

Read the official note. It revised lower-canyon Collector navigation and collision, fixed currents affecting players inside bases, and corrected several inventory-sharing and push-to-talk issues. Saves now track build and branch to prevent incompatible loading into older builds.

If an older route depends on a creature getting stuck, check the Collector changes before trying to repeat it.

August 19, 2026 — Buddy System / EA 1.2

Read the official release notes. Proximity voice, revives, direct item exchange and emotes shipped. Signals, base placement and pinned recipes also received improvements.

For current usage and a troubleshooting sequence see multiplayer. For changed farming behavior see Metal Farms. Do not confuse this major feature release with the subsequent September and October maintenance releases.

July 8, 2026 — Adaptive Measures / EA 1.1

Read the official release notes. This earlier update added Biolabs, expanded Biomod unlocks, introduced out-of-water sprint and a FOV slider, and changed wreck puzzles and several tool interactions. It remains useful historical context but is not the latest build.

Before filing a bug report

Our recommendation is to record platform, build, branch, host/client status, expected result and the shortest steps that reproduce the problem. Include whether mods were enabled. The developer asks players to disable outdated mods after hotfixes while compatibility catches up; follow the current support instructions for your installation.

The October 15 dev-vlog announcement previews future work. It is not an additional patch in this release history.
