Unknown Worlds just dropped their first dev vlog since Subnautica 2 hit Early Access on May 14, 2026, and the update roadmap is far bigger than most players expected. The vlog, titled “Swimming Forward,” was presented by Design Lead Anthony Gallegos and confirmed the studio’s first major content drop for Early Access, EA 1.1, which will add a brand new biome, bring back one of the series’ most beloved vehicles, and push the story forward without wiping your save.

The game already sold over 4 million copies in under a week and generated more than $100 million in gross revenue, making it one of the fastest-selling survival games on Steam this year. These numbers are pure sales and do not include Game Pass or GeForce Now subscribers. With that kind of player base, the pressure on this first content update is real, and based on what the team revealed, they know it.

Here is a full breakdown of what EA 1.1 is bringing, what smaller patches are shipping first, and what multiplayer players can expect in EA 1.2.

The Collector Leviathan Finally Gets Its Own Biome

The biggest piece of EA 1.1 is a new, dedicated region built around the Collector Leviathan, one of the most talked-about creatures in the current game. Players who have already finished the main story have encountered the Collector, but right now it does not have a proper home zone. That changes with this update.

According to Gallegos in the dev vlog, this new biome will be “the scariest the game has been yet”. The region is described as progression and story-driven, meaning it ties directly into the existing narrative rather than sitting as a side area you can ignore. It will include new creatures, new resources, and new wreckage environments to explore, which is something early access players have been asking for since launch.

The studio confirmed the new biome is designed so that you can jump straight in from an existing save file, with no restart required. If you have spent dozens of hours building a base, your progress is safe.

The Prawn Suit Is Coming Back and It Is Built for This Biome

Gallegos teased the return of a fan-favorite vehicle with three words: “Get ready to get stompy.” That is as close to a direct confirmation as you get. The Prawn Suit, the bipedal mechanical walker from the original Subnautica, is returning as a new chassis tied to the EA 1.1 content drop.

In the original game, the Prawn Suit was the go-to tool for navigating dangerous deep-sea environments, mining hard resources, and surviving encounters with aggressive creatures in tight spaces. The new biome tied to the Collector Leviathan sounds like exactly the kind of place it was built for. Wreckage-heavy terrain, aggressive leviathan class fauna, and dense exploration zones are all confirmed for the update.

No full specs on the Subnautica 2 version of the suit have been released yet, but given how story-gated the new biome is intended to be, expect the Prawn Suit to feel like a genuine progression milestone rather than an early-game toy.

Quality-of-Life Fixes Arriving Before the Big Content Drop

Before EA 1.1’s major content lands, Unknown Worlds is shipping a string of smaller patches covering the feedback they have collected since launch. Confirmed items on the list include:

  • Biomod system improvements, with more passive slots available and additional Biomod options added to earlier parts of the game

  • Blight encounter readability fixes, so parasite aggression is more clearly telegraphed to players

  • Voiceover priority system, making sure the most important information plays when it matters most

  • PDA voice log replay, so you can go back and listen to logs you missed or want to revisit

  • Sprint added as a movement option

  • Storage cache expansion for inventory management

  • Vehicle docking and fabrication improvements

  • Wreck gameplay updates to make wreck exploration feel closer to the depth the original games offered

These are not glamorous additions, but they address some of the most common complaints on Steam and Reddit since launch. The sprint addition alone has been one of the most requested features since day one.

Multiplayer Players Get Their Own Wave of Updates in EA 1.2

Co-op in Subnautica 2 supports up to four players and has been one of the game’s standout features, but the launch version has some clear gaps that EA 1.2 is targeting directly. Confirmed for the multiplayer-focused update:

  • Proximity voice chat, removing the clunkier full-lobby chat system currently in the game

  • Character emotes for non-verbal communication and expression in sessions

  • Expanded character customization, giving players more ways to differentiate their appearance from teammates

  • HUD improvements and further co-op session stability fixes

The team acknowledged that co-op uptake exceeded their projections, which is why EA 1.2 is being given its own dedicated update slot rather than being folded in as minor additions.

What Is Not in This Update

It is worth being clear about scope. The larger, deeper late-game regions hinted at in the current story, including what appears to be a significant tree-based landmark, are not part of EA 1.1 or EA 1.2. The studio has confirmed Subnautica 2 will stay in Early Access for two to three years before reaching version 1.0, and the full story conclusion is tied to that final release.

EA 1.1 is filling in a gap in the existing world rather than pushing toward the endgame. Think of it as deepening what is already there rather than cracking open the late-game map. That is a deliberate design call, and it lines up with how Unknown Worlds handled content pacing in the original Subnautica during its Early Access run.

There is also no confirmed release date for EA 1.1 yet. Based on the dev vlog language and pacing of the smaller hotfixes, mid to late July 2026 is a reasonable window, but nothing has been officially announced.

What to Do Right Now If You Are Playing

If you are deep into a playthrough and worried about save compatibility, relax. Unknown Worlds have directly stated that EA 1.1 is designed to be picked up from existing files. There may be a single large wipe before version 1.0 ships, but that is not happening with this update.

If you have not started yet, this is a good time to get in and build up your base before the Collector’s biome opens. The new region is story-gated, so you will want to be reasonably progressed to access it at launch. The sprint and Biomod improvements landing before EA 1.1 also mean the early game experience is getting noticeably better in the next few weeks.

Keep an eye on the official Unknown Worlds channels and the Subnautica 2 Steam page for the EA 1.1 release date announcement. Given how active the team has been with hotfixes since launch, the next dev vlog should follow soon.
