Current patch, changed guides and Early Access limits

Quick answer

This edition records Early Access 1.2 Buddy System and Hotfix 2, published October 6. Hotfix 1 and its September 3 turbine amendment remain in the history. The developer says rollout may take time; experimental features and planned Early Access 2 are separate.

October 15: Early Access 2 preview, not a released update

The Voyage to Early Access 2 Begins post introduces a developer-vlog series with sneak peeks toward the next big content update. It announces neither a shipped Early Access 2 patch nor a release date. Buddy System Hotfix 2 (October 6) remains the latest released update identified in the fetched official feed.

Available in Early Access; full release date unknown

Subnautica 2 entered Early Access on May 14, 2026. Steam and Epic offer the Windows game now; Xbox lists it as Game Preview for PC and Xbox Series X|S. These are released Early Access versions. The full 1.0 release date remains unknown.

Steam gives an estimated Early Access duration of two to three years, with no fixed completion date. The roadmap describes future improvements and expansions; a roadmap entry does not establish a released feature. The latest official update found in the publisher news and Steam announcement feed on October 8 is Buddy System Hotfix 2, published October 6.

Hotfix 2: match the reported fix to your symptom

Unknown Worlds reports fixes for local/remote voice detection, the host appearing dead after a client dies, Tadpole docking and out-of-bounds teleporting, and Scanner Station resource accuracy. It also reports power loss or incorrect readings after Thermal/Hydroelectric Generators and Turbines stream out and back.

The note fixes an Xbox audio-command memory leak while paused or constrained, updates crash diagnostics and re-enables crash-on-launch reporting. It does not diagnose every crash or promise to recover a damaged save. VSync should be disabled when DLSS Dynamic FrameGen is selected. Compare your installed update and exact symptom before applying an older workaround.

Hotfix rollout may take time worldwide. The publisher repeats its warning to disable incompatible community mods after updating and restore them after their creators update them. These are developer reports; Kingy has not reproduced the changes.

What is verified in this edition

Tool and resource routes use attributed published walkthroughs checked against the official update feed. Kingy has not independently played these routes. Distances are approximate; a current patch can move objects or alter requirements.

The source watcher queues changed pages for review. A failed endpoint retains its previous baseline. The public coverage list tracks remaining late-game routes, complete recipes, creature behaviour and independently recorded maps.

Other Hotfix 2 fixes to check before using an old workaround

The October 6 notes say Shiver Leviathans no longer interact with unpiloted vehicles, and report an improved Leviathan grab attack against the Tadpole. They also fix moved Biobeds showing the wrong mesh after a reload, visually duplicated tools on moving Carryable Racks, missing black-box signal names and currents in Overgrown Ruins.

Scanning fixes cover habitat display-case data, the small scanning hitbox for the item called Advance Battery in the notes, and Bloom Biofilm icons and UI. These reports do not establish new blueprint locations, crafting costs or scan counts.
