Buddy System Hotfix 1
The September hotfix is a save and co-op stability pass
Unknown Worlds shipped Buddy System Hotfix 1 on September 1, 2026 UTC. The follow-up patch records save build and branch metadata, restores affected in-progress Axum Powerplant Turbines, fixes Refund Base wall-rack returns and Proximity Chat push-to-talk, and addresses Collector Leviathan pathing, Water Slug markers, Scout Ray collision, Tadpole oxygen and inventory-sharing, UI, compile, crash, and stability issues. A September 3 note says affected turbine ghosts return and can be completed for free.
Our take: Make the current-build check the first step: update every player, confirm the branch and build, back up SaveGames, and reload before replacing a missing turbine or changing cloud files. Keep the patch name distinct from the original May Early Access Hotfix 1, and keep exact route values behind current-build checks.
Buddy System Hotfix 1 ↗ EA 1.2 Buddy System
Buddy System turns the co-op roadmap into a live update
Unknown Worlds shipped Early Access 1.2 on August 19, 2026. The update adds proximity voice chat, revives before reprinting, direct player trading, Wave / Clap / Thumbs Up / Thumbs Down / Frustrated emotes, Tracking Tags, new Jegna and Grace character options, and a large multiplayer, base-building, performance, and save-stability fix pass.
Our take: Treat these as current public-build features, but keep exact menu labels and edge-case behavior patch-sensitive. Link co-op questions to the multiplayer and cross-platform pages, and use the patch note for the full fix list rather than turning every low-volume fix into a separate issue page.
Early Access 1.2 Buddy System update ↗ Experimental branch
Steam now has an opt-in Experimental preview branch
Unknown Worlds announced the Experimental branch on August 12, 2026 UTC. It previews upcoming content and fixes, can contain game-breaking bugs, does not update daily for now, and keeps its saves separate from the main Early Access branch.
Our take: Route preview-build questions to the Experimental news page, save-file and cloud-sync guides, and troubleshooting. Do not copy Experimental-only values into normal wiki pages until the same change ships to the main branch.
Experimental branch announcement ↗ Hotfix 4
Hotfix 4 fixes remain relevant beneath Buddy System
The July 14 Steam appnews post fixes Angel Combs not opening for some players, water currents appearing inside player bases, the FOV slider not showing on Xbox, and two low-volume crashes on Xbox session-invite join and creature spawn. It repeats the standing mod-disable-before-launch rule and notes worldwide and Xbox-certification rollout may take time.
Our take: Keep Hotfix 4 attribution on its specific fixes, but use Buddy System Hotfix 1 as the current public-build baseline. EA 1.2 layers the multiplayer features on top of Adaptive Measures, and its September hotfix adds the newest save, co-op, base, creature, and stability fixes; exact recipe, spawn, encounter, and base-building values remain patch-volatile.
Early Access Hotfix 4 ↗ EA1.2 roadmap
EA Update 1.2 Buddy System has shipped
The August 19 official announcement confirms that the co-op-focused EA Update 1.2, named Buddy System, is live. It adds proximity voice chat, player revives, direct trading, emotes, Tracking Tags, new character options, and a broad multiplayer/base-building fix pass.
Our take: Route players with co-op questions to the Buddy System update and multiplayer pages. Keep the later expansion (Collector Leviathan habitat, next story chapter, and new vehicle chassis) as future roadmap context until it ships.
Early Access 1.2 Buddy System update ↗ Store momentum
Subnautica 2 crossed 5 million copies ahead of Adaptive Measures
A July 9 PC Gamer story syndicated through Steam announced more than 5 million copies sold ahead of the first content update, building on the earlier 1M first-hour, 2M in 12 hours, and 4M in under a week checkpoints.
Our take: Treat this as demand and visibility context, not a gameplay update. It supports keeping update, co-op, bug, route, and wiki pages fresh while Buddy System is the current public feature baseline.
Steam news feed / PC Gamer ↗ Hotfix 3
Hotfix 3 remains a historical patch reference
The June 1 Steam appnews post upgrades DLSS to 4.5, fixes DLSS crashes and settings persistence, restores Frame Generation availability in affected versions, cuts Interior Wall costs, adjusts Hammerhead, Nibbler, and Marrowbreach behavior, and fixes several co-op / state issues.
Our take: Use Hotfix 3 for its specific historical performance, creature, vehicle, base-building, multiplayer rejoin, Strike Armor, and Tadpole Haul Chassis fixes. Buddy System Hotfix 1 is now the public baseline; keep exact damage, recipe, spawn, and route values behind in-game checks.
Early Access Hotfix 3 ↗ Creature preference
Creature discussion is shifting from complaints to favorite weird designs
The May 29 Steam news feed surfaced PC Gamer coverage about player picks for the freakier Subnautica 2 creatures. That does not confirm new fauna, but it does show that creature identity and memorable silhouettes remain a strong search and community topic.
Our take: Use this as demand support for improving the creature hub, creature images, and scan notes. Do not open new creature pages from media polls alone; wait for official media, in-game checks, or repeated independent support.
Steam news feed ↗ Business context
Krafton bonus-deal coverage is now part of the wider launch conversation
The May 28 Steam news feed surfaced external PC Gamer and PCGamesN coverage about Krafton, Unknown Worlds, and a reported Subnautica 2 bonus-deal dispute. This is not a gameplay patch and does not change any guide facts.
Our take: Keep this as context for community trust and business-news searches. Do not turn it into a Known Issues row, roadmap claim, or developer-intent conclusion unless Unknown Worlds or Krafton publish a direct statement.
Steam news feed ↗ Creature balance
Hotfix 3 continues the predator-readability pass
The loudest post-launch gameplay debate is still hostile creature readability: when to flee, when a flare should work, how long a stun should buy, and whether bases or vehicles give reliable protection.
Our take: Hotfix 3 says Hammerheads no longer attack unpiloted Tadpoles, Nibblers have lower perception and speed but higher damage, and Marrowbreaches hit harder but less often. Creature pages should mention these facts without publishing fixed damage, timing, or safe-distance numbers before testing.
Early Access Hotfix 3 ↗ EULA and analytics
Privacy and Terms questions are still part of the launch conversation
Steam reviews and wider discussion still mention the EULA, analytics timing, and whether players can turn data collection off. This is separate from gameplay balance, but it affects trust.
Our take: Hotfix 2 adds an in-game telemetry callout, says analytics can be disabled from settings, and revises sections of the Terms of Service and Privacy Policy. Describe those official actions without giving legal advice or implying all concerns are resolved.
Early Access Hotfix 2 ↗ Crossplay rollout
Different-version errors can be rollout timing, not broken crossplay
After a hotfix, mixed Steam, Xbox, and Game Pass groups can temporarily see different builds. Players often read that as crossplay failure because the symptom appears at join time.
Our take: Hotfix notes can take time to roll out worldwide. Our multiplayer and cross-platform pages should lead with version/build checks before NAT, ports, or account troubleshooting.
Steam discussions ↗ Guide demand
Angel Comb, biomods, Conduit Crystal, and leviathan routes are pulling searches
The Steam news feed is surfacing external guides for Angel Comb, all biomods, leviathan locations, and Conduit Crystal. Other broad reference sites are using the same demand to grow item and route pages.
Our take: Answer these as conservative hubs, map-backed route leads, and search prompts until recipes, locations, and scan text are stable across Early Access patches.
Steam news feed ↗ Co-op state bugs
Rejoin and vehicle-state reports now have Hotfix 3 fixes
Recent reports cluster around rejoin state, vehicle passenger visuals, Tadpole state after death or reload, creatures appearing near bases, save-load freezes, and co-op desync. Some symptoms now have official fixes, while nearby reports still need clean repro data.
Our take: Hotfix 3 fixes clients reverting to a previous position when rejoining multiplayer, Strike Armor additive stacking, Tadpole Haul Chassis passenger goggles, and rare startup crashes. Keep collecting platform, host/client role, build, save-state, and vehicle-state details for symptoms outside those exact fixes.
Early Access Hotfix 3 ↗ Reception scale
The launch wave is still large, and review sentiment is holding
The September 4 Steam review API still shows a Very Positive verdict: 115,470 positive out of 126,775 all-language reviews. The English-language API checkpoint remains Very Positive at 71,971 positive out of 77,256 total reviews.
Our take: High volume raises the bar for fast, careful corrections. Our updates, known issues, and freshness labels need to stay more useful than broad reference pages that mostly lean on raw entity count.
