What changed
What to do now
Unknown Worlds says it is moving from frequent rapid hotfixes toward the EA1.1 update.
- Who should care
- Players waiting for new content, co-op groups planning a return date, and guide writers deciding how often to retest launch-week advice.
- What to do now
- Keep using Hotfix 3 as the current live baseline, but treat EA1.1 features as upcoming until patch notes ship.
- What to test again
- Roadmap and update pages should separate live hotfix behavior from EA1.1 planning and avoid promising an exact release date beyond the official few-weeks wording.
Hotfix 3 already changes DLSS behavior, Interior Wall costs, Hammerhead and Tadpole behavior, Nibbler and Marrowbreach tuning, multiplayer rejoin behavior, Strike Armor stacking, ToS localization, and crash reports.
- Who should care
- DLSS users, base builders, Tadpole pilots, players testing creature pressure, co-op clients rejoining sessions, and anyone diagnosing startup or hard-to-reproduce crashes.
- What to do now
- Confirm your build is on Hotfix 3 before treating an older performance, building-cost, creature, armor, or co-op workaround as current.
- What to test again
- Tadpole, no-weapons, Moonpool, and route-start pages should not stop at Hotfix 2 assumptions when the next guide pass happens.
The dev vlog previews smaller upcoming work on biomods, wreck gameplay, voice-over priority, PDA voice-log replay, emotes, proximity voice chat, and player customization.
- Who should care
- Biomod planners, lore players, co-op groups, accessibility-sensitive players, and anyone deciding whether to wait for social or quality-of-life features.
- What to do now
- Use these as watchlist items, not current guide steps; do not rebuild a route around multiple passive biomod slots or proximity chat until EA1.1 patch notes confirm the shipped details.
- What to test again
- Biomod, co-op, audio-log, and beginner-route explainers need a fresh pass when the smaller updates land.
A later major content drop is planned around a new Collector Leviathan region with a new chassis, creatures, resources, and progression/story content, with the stated goal of letting players continue existing saves.
- Who should care
- Players who have finished the current build, spoiler-sensitive explorers, map users, resource-route writers, and players worried about restarting their save.
- What to do now
- Keep your current save, but do not assume current Collector Leviathan routes, resource positions, or vehicle progression will stay final.
- What to test again
- Map, Tadpole, resource, and progression pages need version labels and a full retest when the new region ships.
What changed now
The newest official Subnautica 2 update signal is not another long patch note. Unknown Worlds published Swimming Forward on June 4, 2026, after releasing Early Access Hotfix 3 on June 1, 2026. Together, they set the current player baseline: Hotfix 3 is the live patch to check first, and EA1.1 is now the next update target.
If you are playing today, update before troubleshooting DLSS, Interior Wall costs, Hammerhead behavior around Tadpoles, Nibbler and Marrowbreach pressure, multiplayer rejoin position bugs, Strike Armor stacking, or startup crashes. If you are waiting for more content, do not treat the EA1.1 preview as live until Unknown Worlds publishes the actual patch notes.
Hotfix 3 is the current live baseline
Hotfix 3 is practical even though it is not a content expansion. It fixes DLSS crashes and settings persistence, upgrades DLSS to 4.5, restores Frame Generation where it was missing, reduces Interior Wall costs, and fixes several crash and multiplayer issues.
Creature and vehicle advice also needs a new version check. Hammerheads should no longer attack unpiloted Tadpoles, but the official note still says they can take an interest in Tadpoles. Hammerheads should also be attracted to Flares more reliably. Nibblers now see players from a shorter distance, circle longer before attacking, move more slowly, react more to the Multitool, and hit harder. Marrowbreaches hit harder too, but attack less often.
That means older Hotfix 2 advice is not enough for Tadpole, Moonpool, and no-weapons pages. The right question is no longer only “are you on Hotfix 2?” It is now “are you on Hotfix 3 or later?”
EA1.1 is next, but the preview is not patch notes
Swimming Forward says Unknown Worlds is pivoting away from the rapid launch-hotfix pace and focusing on EA1.1. The official post says to watch for it in a few weeks, but it does not lock an exact day.
The video preview lists several upcoming smaller changes: more passive biomod slots, more early-game biomod options, wreck gameplay improvements, voice-over priority so important information is easier to hear, PDA voice-log replay, emotes, proximity voice chat, and more player customization.
Those are guide watchlist items, not current instructions. A co-op group should not assume proximity voice chat is available today. A route writer should not balance early biomod advice around multiple passive slots until the shipped update confirms the exact unlocks, limits, and UI.
Save players should wait for shipped details, not restart
The larger content preview is the part most likely to affect route pages. Unknown Worlds says the next major content drop will include a new region tied to the Collector Leviathan, a new chassis, new creatures, new resources, and progression/story content. The stated goal is for players to continue from their existing saves instead of starting over.
That is useful, but it is still not a promise that every current route, resource position, or creature behavior will stay stable. If you have finished the current build, keep the save and wait for the patch. If you maintain routes, maps, or resource pages, mark Collector-region claims and vehicle-progression claims for a full retest when the update lands.
What players are asking about
The community discussion around the dev vlog is centered on the teased chassis, the Collector Leviathan region, proximity voice chat, PDA voice-log replay, and whether console settings should get more options. Those are good clues for what players will search next, but they do not change what is live in Hotfix 3.
For now, the safest player action is simple: update to Hotfix 3, keep your save, treat EA1.1 as upcoming, and recheck guide pages after the next official patch notes arrive.
