Subnautica 2 Buddy System Update Adds Proximity Chat, Player Revives and Trading

Subnautica 2’s Latest Early Access Update Makes Co-Op Survival More Social, More Dangerous and Much Easier for Friends

Players need to communicate underwater, share resources, rescue teammates and coordinate their exploration.

The Buddy System update is designed to make those interactions considerably easier without removing the danger that makes Subnautica memorable.

Proximity Voice Chat Finally Arrives

The headline feature of Update 1.2 is proximity voice chat.

Players can now communicate with nearby teammates through cross-platform voice chat.

The system is designed around distance rather than a traditional always-clear party channel. As players move farther away from one another, their voices become harder to hear. The game can transition the audio toward a radio-style effect before the signal eventually becomes too weak to hear clearly.

This is particularly interesting for a survival game set underwater.

In a conventional multiplayer game, teammates can communicate from almost anywhere through a party system.

Subnautica 2 instead makes communication part of the environment.

A player exploring a dangerous cave may hear a teammate's voice becoming increasingly distant.

Someone swimming away to collect resources may suddenly lose contact with the rest of the group.

That can make exploration feel more immersive while also creating unexpected moments when players become separated.

Why Proximity Chat Could Change Multiplayer Exploration

Communication is extremely important in Subnautica 2 because players often split up while searching for resources and locations.

One person might investigate a wreck.

Another could gather materials.

A third player might remain near the base.

With normal voice chat, everyone can communicate regardless of distance.

Proximity chat changes that dynamic.

Players have to stay relatively close if they want to maintain clear communication.

That could encourage groups to explore more carefully.

It also creates opportunities for genuinely funny multiplayer moments.

A teammate disappearing into a dark cave while everyone else hears their voice slowly fading away could become a memorable part of an expedition.

More importantly, the system can increase tension.

When players cannot hear one another clearly, the ocean suddenly feels much larger.

Player Revives Make Team Survival More Forgiving

Another major addition is the ability for players to revive one another.

Previously, a player who went down could eventually need to reprint and return to the action.

Update 1.2 gives teammates a limited opportunity to rescue them before that happens.

A downed player can be revived by another player, with the rescuer sharing oxygen to bring their teammate back. Revived players retain their equipment and receive a small amount of oxygen.

This changes the consequences of multiplayer mistakes.

If someone gets into trouble deep underwater, the rest of the team now has a reason to attempt a rescue rather than simply watching their teammate disappear.

That fits naturally with the game's cooperative design.

It also creates another strategic decision.

Should a player risk entering a dangerous area to rescue a teammate?

Or should they leave the downed player behind and return to safety?

The revive system does not remove danger. Instead, it gives coordinated teams another tool for surviving it.

Players Can Now Trade Items Directly

Resource management is another major part of Subnautica 2.

Players constantly collect materials, equipment and other useful items while exploring.

The Buddy System update makes sharing those resources easier.

Players can now interact directly with one another and exchange inventory items.

This removes some of the unnecessary friction from cooperative resource gathering.

Instead of dropping an item and hoping another player picks it up correctly, teammates can exchange resources directly.

That could be particularly useful when one player has excess materials while another is missing a critical component.

It also strengthens the game's cooperative identity.

Players are no longer simply exploring the same world together.

They can actively support one another through resource management.

The New Tracking Tag Adds Another Useful Tool

Update 1.2 also introduces the Tracking Tag.

The item can be placed inside certain carryable objects, such as lockers, and functions as a short-range beacon.

The Tracking Tag can also increase black box range when it is present in the player's hand or inventory during reprinting.

While it may not receive as much attention as proximity chat, this type of utility can become extremely valuable during exploration.

Subnautica 2 encourages players to move through large environments, and keeping track of important resources or locations can become difficult.

A dedicated tracking tool gives players another way to organize their expeditions.

New Emotes Make Multiplayer More Expressive

The update also adds several player emotes.

Players can now use Wave, Clap, Thumbs Up, Thumbs Down and Frustrated animations through a new radial menu.

The emotes can be activated both underwater and on land and can be interrupted by gameplay input.

At first glance, this might look like a minor addition.

For multiplayer survival games, however, communication is not always about words.

Emotes can provide quick visual signals when players are busy, underwater or unable to communicate clearly.

A simple thumbs-up can indicate that a teammate should continue.

A wave can signal where someone is located.

A frustrated animation can communicate a reaction without interrupting the expedition.

New Characters and Customization Options

Update 1.2 also adds two new character options: Jegna and Grace.

Players can use the new characters through the game's character customization system, while two additional color schemes have also been added.

This gives multiplayer groups more visual variety.

Customization is particularly useful in cooperative games because players need to quickly identify teammates during chaotic situations.

When several people are exploring the same underwater area, recognizable characters can make communication and coordination easier.

Base Building Gets Multiplayer Improvements

The Buddy System update is not limited to social features.

Unknown Worlds has also made several improvements to base building.

The placement interface now includes alignment guide lines, making it easier to position structures correctly.

The Move mode has also been improved for clients in multiplayer sessions.

Size snapping has been updated as well, allowing players to fully deconstruct certain rooms using the Shrink function.

The update even gives the in-game trashcan a real purpose: items placed inside it are destroyed individually after a short delay.

These changes may sound small, but quality-of-life improvements can make a major difference in a survival game where players spend significant amounts of time building and organizing bases.

Creatures and Combat Receive Adjustments

Unknown Worlds also made changes to several creatures.

Marrowbreach, Hammerhead, Nibbler, Needlershark, Epicurean and Twin Eel now have additional flinch animations and visual effects.

Bulletheads have been adjusted to deal more damage but can also be dodged under the right circumstances.

The update also adds more Coral Crab animations and revises the Bloom Parasite's model and animations.

These changes make encounters feel more responsive while improving the visual feedback players receive during combat.

That is particularly important underwater because enemy attacks can sometimes be difficult to read.

Clearer animations can help players understand what is happening before deciding whether to fight or escape.

Vehicle and Tool Improvements

Several tools and vehicles have also received adjustments.

The Feedback Resonator now stuns creatures instead of causing them to flee.

The Sonic Resonator's creature-stun duration has been increased to 10 seconds.

Acid sources now appear as green dots in the Scanner HUD.

The Repair Tool also unlocks after two scans, providing a clearer progression path for players.

These changes demonstrate that the Buddy System update is not simply a social patch.

It is a broad Early Access update that improves many areas of the game while continuing to refine the underlying survival experience.

A Huge Number of Bug Fixes

Unknown Worlds also included an unusually large collection of bug fixes in Update 1.2.

The fixes cover multiplayer synchronization, bases, creatures, vehicles, visual effects, audio, saving, performance and user-interface problems.

Several fixes specifically address community feedback, including issues involving multiplayer desynchronization, player markers, base construction and resource systems.

This is important for an Early Access game.

Subnautica 2 is still being developed, so technical improvements are just as important as new features.

A smoother multiplayer experience gives players a stronger foundation for the larger updates still planned for the game.

Early Access 2 Is Still Coming

The Buddy System update is not the end of Subnautica 2's Early Access development.

Unknown Worlds has confirmed that work continues on the larger Early Access 2 update.

The studio has previously indicated that this future update will expand the game with a new region, additional story content, new progression elements and vehicles.

That makes Update 1.2 more of a foundation-building release.

The developers are improving how players interact with each other now while continuing work on the larger content expansion.

For players already enjoying the Early Access version, this provides a clear reason to keep following development.

Why This Update Matters for Subnautica 2

The biggest change is not any individual feature.

It is the way these systems work together.

Proximity chat encourages players to stay connected.

Trading lets teammates share resources.

Revives give groups a reason to rescue one another.

Emotes make communication more expressive.

The Tracking Tag improves organization.

Together, these features make Subnautica 2 feel more like a genuine cooperative expedition.

That is particularly important because multiplayer survival games can easily become little more than several players occupying the same world.

The Buddy System update pushes Subnautica 2 toward something more collaborative.

Players have more reasons to depend on each other.

Should You Return to Subnautica 2 Now?

For players who already own Subnautica 2 in Early Access, Update 1.2 is a strong reason to return.

The multiplayer features are significant enough to change how cooperative sessions feel, while the large number of fixes should make the overall experience smoother.

New players interested in cooperative survival games may also find this a particularly good time to start.

The game is still unfinished, and the larger Early Access 2 update is still ahead, but the Buddy System provides a much stronger multiplayer foundation.

Players should simply remember that Early Access means systems and content can still change substantially before the final version.

Conclusion

Subnautica 2's Early Access 1.2 Buddy System update is one of the game's most meaningful multiplayer improvements so far.

The update adds cross-platform proximity voice chat, player revives, direct item trading, new emotes and the Tracking Tag, while also improving base building, creatures, vehicles, tools, performance and numerous technical issues.

The most exciting addition may be proximity chat because it changes how players communicate during exploration.

Instead of having unlimited long-distance communication, teammates must remain close if they want to hear each other clearly.

Combined with revives and trading, the new systems encourage players to cooperate more closely.

And this is only part of the game's ongoing development.

Unknown Worlds is still working toward the larger Early Access 2 update, which is expected to bring a new region, additional story content, progression changes and vehicles.

For anyone waiting for Subnautica 2 to become a stronger cooperative survival experience, the Buddy System update is a significant step in that direction.
