Every feature in version 1.2 of Subnautica 2 can be traced directly to a documented player request — and Unknown Worlds made that traceability visible in the patch notes themselves. The studio tagged each community-sourced fix with a snorkel icon (🤿), turning what would otherwise be a routine update announcement into a public accounting of whether its Early Access feedback model actually works. Yesterday’s Buddy System update, the second major update since the May 14 Early Access launch, answers that question with roughly 50 community-attributed fixes and every co-op feature the player base had been requesting since the earliest Steam discussions in 2024.

For context: Subnautica 2 is a four-player co-operative survival game set on Proteus, a lethal alien ocean moon where the CICADA colony ship crashed after an inexplicable course diversion. Players arrive with nothing, survive by exploring the ocean floor, crafting tools, and building underwater bases, while an AI called NoA guides them through a mystery involving genetic engineering and ancient alien civilizations. The ocean is spectacular and actively hostile — beautiful bioluminescence masking crushing depths, rare resources, and creatures that will kill you without a second thought. With death originally meaning an immediate respawn back at your home Biobed and the loss of whatever you were carrying, the co-op loop had real friction. Buddy System addresses that friction at every level.

Proximity Chat Turned Into Immersion Engineering

The headline feature is cross-platform proximity voice chat, and Unknown Worlds built it to maintain the game’s atmosphere rather than simply bolt on a convenience feature. The proximity chat feature specifics are described in full in the official patch notes.

The underlying mechanism uses Unreal Engine 5’s built-in spatial audio capabilities to simulate radio communication rather than direct speech. When players are close together, their voices sound clear and directional. As physical distance between players increases, the audio degrades gradually into a radio-static effect, becoming harder to parse and eventually cutting out entirely. Three toggle options — always on, push to talk, always off — give individual players control over how they participate.

This specific design was described, nearly word for word, by a Steam community member in October 2024, more than a year before the feature shipped: “Local radios with proximity chat, the further you get away from someone the more ‘static-y’ they become.” The original Steam community discussion dates to October 17, 2024. The community’s suggestion even extended to vessels having longer communication ranges — an idea the studio has not implemented yet but may inform future updates. The gap between proposal and shipped feature illustrates the feedback pipeline the studio has been describing since launch.

Other co-op survival games have tackled proximity chat differently. Lethal Company uses proximity voice without the degradation effect, keeping communication clean even across moderate distances. Phasmophobia applies wall-muffling to simulate physical barriers. Subnautica 2’s radio-static approach suits an open-water environment where the audio illusion needs to be “radio communication failing in the deep” rather than “walls blocking sound.” PCGamesN’s Buddy System coverage details the comparison with other co-op titles.

Creative Director Anthony Gallegos, in a video blog released the day before the update, described the degradation as adding to the exploration tension rather than working against it. The update vlog from August 18 is available on the Unknown Worlds site.

Drowning Doesn’t Have to Mean Losing Everything

The player revive system fundamentally redesigns what death costs in co-op. Previously, dying sent you back to your assigned Biobed immediately — equipment lost wherever you fell. The revive mechanics are detailed in the version 1.2 patch notes.

Now there is a window between dying and reprinting. A teammate who reaches a downed player can share oxygen with them, bringing them back with all gear intact and a small oxygen reserve restored. The window is short enough to create genuine urgency — swimming across a dangerous biome to reach a fallen crewmate adds a new layer to survival decisions — and the downed player retains agency throughout: choosing to immediately reprint to the Biobed rather than wait is always an option.

The design aligns Subnautica 2 with other co-op survival games that use rescue mechanics as a social adhesive — most notably Deep Rock Galactic and Lethal Company — while keeping the original Biobed system intact as the fallback. The gear-preservation benefit makes the rescue worth attempting even when it requires risk, which is how the mechanic creates the tension it’s designed to create.

Pocket-to-Pocket Trade Requires Showing Up

Inventory trading in multiplayer previously required dropping items on the ocean floor and hoping they didn’t drift into a crevice. Version 1.2 replaced that approach with a direct-access system that requires physical proximity to work. The trading system patch notes confirm the proximity requirement.

Walking up to a crewmate and holding a button opens their inventory for item exchange. A notification alerts the crewmate when someone is accessing their pack. The transaction closes when either player moves away. By requiring physical co-location rather than offering remote trading, Unknown Worlds maintained the game’s spatial logic — sharing resources still means choosing to be in the same place.

What Else Arrived in Buddy System

Beyond the headline co-op systems, the update added two new playable Pioneer character options — Jegna and Grace — along with two new suit color schemes, giving groups of four players more ways to distinguish themselves at a glance. A Tracking Tag item was added to the game: a short-range beacon that can be placed inside containers to mark their location, or carried in your inventory so that if you die, it extends the range of your black box signal, making gear recovery from deep-water deaths significantly less frustrating. The Tracking Tag and character additions are covered in the gameplay section of the patch notes.

The HUD was revised to reduce visual clutter. Distant signal icons now stay small and only enlarge and display text as you approach them, keeping the screen readable during exploration. Creature animations were expanded across six species — Marrowbreach, Hammerhead, Nibbler, Needlershark, Epicurean, and Twin Eel — all gaining flinch reactions for six creatures, making fauna feel responsive rather than passive.

PC players with Nvidia RTX 5000-series cards got two new Frame Generation modes (5x and 6x) alongside Dynamic Frame Generation, which automatically selects the best mode for a given hardware state. The trash can in player bases became operational: items added to it are destroyed one by one after a five-second delay. Base-building alignment guide lines were added. Three biomes — the Tufa Zone, Thermal Area, and North Coral Gardens — received music tracks they previously lacked.

Community Fixed Its Own Bugs

The snorkel-icon system extends beyond the headline features into a substantial share of the bug fix list. Among the community-attributed fixes: Hydroturbines that stopped producing power after roughly 120–160 minutes of gameplay without explanation; Hydroturbine power bug patched with the 🤿 marker; Solar Panels that dropped offline when a player had multiple bases in the same save; Metal Farms that stayed powered after losing their power source and remained active after being moved out of power range; and a battery duplication exploit fixed involving save-and-load cycling that allowed indefinite resource generation.

Other snorkel-marked fixes addressed multiplayer-specific desynchronization issues — clients who couldn’t move Growbed items, cameras stuck in starting Biobeds, an exploit that let clients skip through the prologue’s adaptation requirement by joining sessions mid-sequence — as well as dozens of terrain, collision, localization, and quality-of-life issues that accumulated in the two months since version 1.1. The complete version 1.2 bug fix list runs to several dozen entries.

The sheer density of 🤿 icons in the patch notes accomplishes something that developer statements about listening to feedback cannot: it makes the feedback loop legible. Readers of the patch notes can see, fix by fix, which problems the community identified and which the developer independently found. Unknown Worlds’ feedback submission tool, hosted at Nolt.io, is linked from the update announcement directly.

What Comes Next and What It Means for Early Access

Gallegos used the Buddy System video blog to offer the first glimpse of Early Access 2 content in development. The update vlog’s EA2 preview segment showed a brief clip that appeared to show what might be a pedal-powered underwater vehicle — an early-stage tease rather than a confirmed feature — but suggested the next major update will expand the game’s transportation options alongside the new region currently in development, described since the roadmap as home to the Collector Leviathan.

Subnautica 2 sold five million copies in its first 22 days at $29.99, driving Krafton’s record Q2 2026 with approximately $890 million in revenue, and did so while its studio was in the middle of a corporate governance dispute that only reached settlement on June 30, 2026. The studio is now under new leadership following CEO Ted Gill’s post-settlement departure. What the Buddy System update contributes to that context is evidence that development continued at pace regardless of corporate turbulence, and that the community-feedback model the studio adopted at launch produced a deliverable that matches what the community asked for.

The Buddy System update is available now as a free automatic download on Steam and Xbox. Players who do not see the update may need to restart Steam.

Frequently Asked Questions

How does proximity voice chat work in Subnautica 2 after the Buddy System update?

Proximity voice chat in version 1.2 applies distance-based spatial audio: voices sound clear and directional when players are nearby, then gradually degrade into a radio-static effect as distance increases, eventually cutting out entirely at long range. Players can set chat to always on, push to talk, or always off. The system works cross-platform between Steam and Xbox players. The radio-degradation effect was a design choice to preserve Subnautica 2’s atmosphere of underwater isolation rather than offer flat, always-clear communication. The full proximity chat patch notes are available on the Unknown Worlds site.

What happens when you die in Subnautica 2 co-op now?

Instead of an immediate respawn at your home Biobed, dying now opens a window during which a teammate can swim to you and share oxygen, reviving you with all your equipment intact and a small oxygen reserve. The window is limited, creating urgency. If no rescue comes — or if you prefer — you can choose to immediately reprint and respawn at your Biobed, losing the gear you were carrying as before. The revive system gives co-op groups a meaningful reason to stay aware of each other’s location. The player revive system details appear in the 1.2 patch notes.

What is the 🤿 icon in the Subnautica 2 Buddy System patch notes?

Unknown Worlds tagged each fix that came directly from community-submitted feedback with a snorkel icon (🤿) in the version 1.2 patch notes. Approximately 50 of the update’s fixes carry this designation, making it possible to see exactly which bugs the player community identified versus which the developer found independently. The studio uses a dedicated Subnautica 2 community feedback board at Nolt.io where players can submit ideas and upvote others’ suggestions.

When will Subnautica 2 leave Early Access?

Unknown Worlds has committed to a two-to-three year Early Access window before a full version 1.0 release. The game entered Early Access on May 14 at $29.99; the price will rise at full release. Creative Director Anthony Gallegos has indicated that Early Access 2 — the next major content update, bringing a new region and the Collector Leviathan — is currently in development, but no release date has been announced.
