- Correction:
- The article puts inside quote marks the phrase 'on a new alien world where players are stranded after their colony ship experiences a malfunction during transit' attributed to Engadget. That exact wording does not appear in the Engadget piece. Engadget says 'Subnautica 2 takes place on a new world' and then quotes the game's official in-universe description: 'Driven from your home by ongoing conflict, Alterra offers you the chance at a new life. But as the colony ship CICADA shepherds you and your fellow Pioneers to your new home, something goes awry. The ship's AI insists that your mission should continue. Stranded and faced with near-insurmountable odds, you must do everything in your power to survive.' The substance — new world, colony-ship plot setup, players are stranded — is accurate, but the quote-marked phrase is a paraphrase, not verbatim Engadget text. Either the quote marks should be removed or the wording should match the Engadget passage (or the game's official description) verbatim.
Overview
Unknown Worlds Entertainment will launch Subnautica 2 into Early Access on May 14, 2026 at 08:00 PDT / 15:00 UTC, the studio announced on its official site. The release brings the underwater survival series to multiplayer for the first time, with up to four players able to explore the new alien ocean together. The standard Early Access edition is priced at $29.99 USD, according to Unknown Worlds, with regional pricing handled by individual storefronts.
The launch lands roughly two months after a Delaware court reinstated Ted Gill as CEO of Unknown Worlds, as reported by Game Developer, capping a dispute between Unknown Worlds executives and parent company Krafton over a $250 million earnout tied to the sequel’s launch timing.
What We Know
Release details
Subnautica 2 will be available on Steam, the Epic Games Store, the Windows Store and Xbox Series X|S at launch, per Xbox Wire. Microsoft also lists Xbox on PC and ROG Xbox Ally among supported Xbox platforms, and the game is included day one with Xbox Game Pass Ultimate and PC Game Pass, Xbox Wire reports.
Unknown Worlds enabled pre-purchasing and pre-loading 72 hours before launch, the studio said. Players who buy Subnautica 2 before May 25 will receive a Reaper Leviathan in-game base decoration, according to the official announcement. Only one Early Access edition is available — a standard version with no founder’s bundles or premium tiers, Insider Gaming notes.
Multiplayer and cross-platform play
This is the first Subnautica title to ship with multiplayer support. The Steam product page lists up to four-player online co-op and cross-platform multiplayer as core features. Xbox Wire describes the option to “traverse this mysterious new world alone or with up to three of your friends in optional co-operative multiplayer,” with the ability to invite friends on other platforms directly from the Xbox menu, per Microsoft. PCGamesN frames the same setup as exploring the alien world “alone or with up to three friends in online multiplayer co-op,” in its launch guide.
A developer statement on the Xbox Wire post notes that multiplayer was “one of the most highly requested” features for the sequel and was designed to work “seamlessly with the Xbox friends list,” Microsoft reports.
Setting, engine and content
Subnautica 2 is built on Unreal Engine 5, according to Wikipedia, and the studio has confirmed Ben Prunty as the composer. Engadget describes the premise as a sequel set “on a new alien world where players are stranded after their colony ship experiences a malfunction during transit,” in its preview. The sequel adds an ocean-current mechanic that can carry players between zones and a DNA-modification system that lets players acquire new abilities, as documented on Wikipedia.
Unknown Worlds has also committed to a monetization model with “no subscriptions. No loot boxes. No battle pass. No microtransactions,” as listed on the Wikipedia entry.
Early Access roadmap
The studio expects to remain in Early Access “about 2 to 3 years” based on its prior development pattern with the original Subnautica and Below Zero, per its Steam page. Updates during Early Access are planned to add “more biomes, creatures, craftables, features, and narratives,” the studio writes. Players who purchase during Early Access pay once and receive all updates through the eventual 1.0 release, the developer notes, although the studio has also confirmed the price will rise after Early Access concludes, in its Steam FAQ.
The lawsuit overshadowing the launch
The May 14 release follows a Delaware Chancery Court ruling that found Krafton illegally fired Unknown Worlds’ leadership to avoid paying a $250 million earnout tied to Subnautica 2. Vice Chancellor Lori Will issued the March 16, 2026 opinion holding that “Krafton illegally fired Gill to take over the Subnautica 2 studio,” Game Developer reports. The court reinstated Ted Gill as CEO but did not reinstate co-founders Max McGuire and Charlie Cleveland, as covered in a separate Game Developer report.
The executives had argued that “Krafton schemed to sabotage the Subnautica 2 early access timeline to avoid paying $250 million in payouts,” Game Developer notes, referencing a performance bonus attached to Krafton’s 2021 acquisition of Unknown Worlds. The earnout sits on top of a $500 million acquisition price, according to Game Developer.
The initial early access launch date was announced to IGN by Steve Papoutsis, the CEO Krafton installed after Gill’s removal, Game Developer reported. The reinstated executives initially objected that the announcement violated the court’s order, then withdrew the contention in a letter filed in April, stating they “no longer contend that Krafton violated the Court’s March 16, 2026 opinion,” Game Developer reported.
What We Don’t Know
A second phase of the Delaware case is still pending. That phase will determine whether Krafton wrongfully impaired the earnout and what, if any, damages are due beyond the opportunity to still hit the $250 million payout target, Game Developer reported. Neither side has signalled when that phase will conclude.
A PlayStation 5 release has not been confirmed during Early Access. Sony platforms are absent from both the Steam page and the Xbox Wire launch announcement, although Unknown Worlds has not ruled out PS5 support for a future 1.0 release. The studio has not published a target date for full 1.0 launch, only the two-to-three-year window quoted on Steam.
Why It Matters
The original Subnautica spent “just over three years” in Early Access, according to Insider Gaming, and Subnautica: Below Zero spent about two and a half years in the same model. Adding co-op to a series whose core appeal has always been the isolation of a hostile alien ocean is a notable design shift, and one Unknown Worlds is staging entirely inside an Early Access framework — players pay once at $29.99 and ride out the entire development cycle, according to the studio’s own messaging.
The launch is also a stress test of Krafton’s relationship with its acquired studios. The reinstated founder it tried to remove will lead Unknown Worlds through Early Access while the second phase of the Delaware case, which Game Developer describes as still pending, determines whether the publisher owes damages on top of the still-open path to the $250 million earnout.
