Subnautica Lawsuit 2026: Full $250M Case Breakdown

The subnautica lawsuit is one of the wildest corporate legal battles the gaming industry has ever seen. It centers on a $250 million earnout that publisher Krafton allegedly schemed to avoid paying the creators of Subnautica 2.

In 2026, a Delaware judge sided with the fired Unknown Worlds founders. The ruling confirmed that Krafton breached its own acquisition contract. The CEO of Krafton even used ChatGPT to plot a takeover strategy dubbed “Project X.”

One stat tells the whole story. Subnautica 2 sold 4 million copies in its first weeks, generated over $100 million in revenue, and appears to have triggered the full earnout cap.

What Is the Subnautica Lawsuit

The subnautica lawsuit is a breach of contract dispute between Krafton Inc. and the co-founders of Unknown Worlds Entertainment over a $250 million earnout tied to the success of Subnautica 2. The Delaware Court of Chancery addressed the dispute between Fortis Advisors LLC, representing Unknown Worlds’ former shareholders, and Krafton, the global video game publisher that acquired the studio.

The case centers on the firing of the studio’s co-founders by Krafton, the South Korean gaming giant that acquired Unknown Worlds Entertainment, and it has thrown the future of Subnautica 2 into serious doubt.

This is not a consumer class action or a data breach settlement. It is a corporate acquisition dispute with massive financial stakes. It is a case that touches on developer rights, labor law, and what happens when a big publisher takes over a beloved indie studio.

The case has become a reference point for how post-acquisition disputes play out. It also raises hard questions about what happens when a parent company wants to renege on a deal.

Subnautica 2 Lawsuit 2026 Update

As of mid-2026, the Unknown Worlds founders have won Phase One of the lawsuit, and Krafton has reportedly agreed to honor the $250 million earnout. A report from The Korean Economic Daily citing its own sources claims that Krafton has agreed to pay the $250M bonus, after Subnautica 2 launched and was an instant hit, selling an estimated 4M copies and generating $100M in revenue.

A judge ruled in favor of the studios’ cofounders earlier this year, though the court will still decide exactly how much gets paid out under these new conditions. The Phase Two litigation, which addresses additional monetary damages from the firings, remains pending.

The plaintiffs withdrew a contempt motion in April 2026, requesting the Court remove a June 12, 2026 evidentiary hearing from the calendar. That withdrawal suggested the two sides may be moving toward resolution on at least some contested issues.

• Phase One ruling: March 16, 2026, in favor of Unknown Worlds founders
• Subnautica 2 launch: May 14, 2026, Early Access on Steam
• Reported copies sold: 4 million and counting
• Earnout status: Reportedly triggered; Krafton reviewing payment criteria
• Phase Two: Pending; will determine additional damages

In a statement, a Krafton official said: “Krafton is reviewing the specific payment criteria and amount under the earnout arrangement.”

Krafton and the Unknown Worlds $250 Million Earnout

The $250 million earnout is the financial engine driving this entire dispute. Krafton’s 2021 acquisition of Unknown Worlds included a $500 million upfront purchase price supplemented by a potential $250 million earnout, based on “Group Company Revenue” during a testing period ending December 31, 2025, with the sellers having an option to extend to June 2026.

The formula was aggressive. For every dollar above a $69.8 million threshold, Krafton would owe $3.12, up to the cap. That means if Unknown Worlds’ monthly revenue cleared $69.8 million, the payout math escalated fast.

Think of it like a performance bonus on steroids. A normal bonus might be 10% of profits. This one was designed to reward massive commercial success with a massive check.

That would trigger a $218 million payout for the first month, with the total bonus capped at $250 million. The earnout was designed to reward the founders for building a franchise that continued to grow under Krafton’s ownership.

Key Takeaway: The entire lawsuit boils down to one question: did Krafton fire the founders and delay Subnautica 2 specifically to avoid paying $250 million it contractually owed them?

Subnautica Lawsuit Timeline From 2021 to 2026

Here is the full chronological timeline of events that led to the lawsuit and its resolution.

It wasn’t until a milestone review in May 2025 as Subnautica 2 headed toward Early Access on Steam that the publisher started to worry about those terms. From that moment, the chain of events accelerated rapidly toward litigation.

Who Filed the Subnautica Lawsuit

The lawsuit was filed by the three co-founders and key employees of Unknown Worlds Entertainment: Ted Gill, Charlie Cleveland, and Max McGuire. Vice Chancellor Lori Will issued a decision in the lawsuit filed by Charlie Cleveland, Max McGuire and Ted Gill against Subnautica 2 publisher Krafton.

Central to the deal was the designation of founders Charlie Cleveland and Max McGuire and President/CEO Edward (Ted) Gill as “Key Employees.” As long as any Key Employee remained employed, they were guaranteed operational control of Unknown Worlds in all material respects.

Their claims are represented through Fortis Advisors LLC, which acts on behalf of Unknown Worlds’ former shareholders. “Judgment is entered in favor of Fortis on its Phase One claims,” the Vice Chancellor wrote.

• Ted Gill: CEO of Unknown Worlds, fired July 1, 2025, reinstated March 2026
• Charlie Cleveland: Co-founder, Subnautica designer and director
• Max McGuire: Co-founder, Technical Director
• Legal representative: Fortis Advisors LLC

Cleveland and McGuire both stepped back from day-to-day leadership duties at the studio with the approval of Gill and their partners at Krafton. Their reduced roles later became a central argument Krafton used, unsuccessfully, to justify the firings.

Why Krafton Fired the Unknown Worlds Founders

Krafton fired the three founders on July 1, 2025, claiming they had failed to deliver Subnautica 2 on time and had abandoned their duties. The court rejected both justifications.

“Krafton’s newly manufactured justifications for the terminations are pretextual,” reads the court’s decision. “Cleveland and McGuire had taken on limited roles, but that was long known to and accepted by Krafton. As for the data downloads, the former employees were acting to protect the studio’s work product amid Krafton’s takeover attempt.”

The real reason, according to the court, was financial. Kim, who had personally led the acquisition of Unknown Worlds, felt that Krafton had overpaid. He feared that making an earnout payment would earn him a reputation as a “pushover.”

The judge declared very clearly that Krafton terminated the Unknown Worlds studio heads specifically to avoid paying out that $250 million bonus.

• Krafton claimed founders “abandoned” duties
• Krafton claimed founders stole documents
• Court found both claims were pretextual
• Court found the real motive was avoiding the $250M earnout

Key Takeaway: The Delaware court found that Krafton manufactured reasons to fire the founders specifically to dodge a $250 million contractual obligation.

Krafton CEO, ChatGPT, and Project X

This is where the case gets truly bizarre. Kim expressed frustration internally about being “taken advantage of,” questioned the need to rush the launch, and after being cautioned by his in-house legal counsel that taking action towards the Key Employees could result in a lawsuit and reputational risk, turned to an AI chatbot (ChatGPT) for advice.

His own lawyers told him to stop. He asked ChatGPT instead.

Initially, ChatGPT responded that the earnout would be difficult to cancel, however, after some coaxing, the AI suggested that Kim form an internal task force, dubbed “Project X.”

“Fearing he had agreed to a ‘pushover’ contract, KRAFTON’s CEO consulted an artificial intelligence chatbot to contrive a corporate ‘takeover’ strategy,” Vice Chancellor Lori Will said in her ruling.

The ChatGPT-generated strategy included several aggressive tactics:

• Preemptive public messaging to shape fan and legal perceptions
• Locking down Steam publishing rights and access to the development pipeline
• Maintaining leverage over the earnout
• Preparing systematic legal defenses

Kim did as the chatbot recommended and locked down the publishing, and Subnautica 2 could not be released. The court took note that Kim admitted at trial he had deleted specific relevant chat logs.

Imagine getting legal advice from a chatbot after your actual lawyers warned you not to act. Then following the chatbot’s plan step by step. That is essentially what happened here.

Delaware Court Ruling on the Subnautica Case

The key ruling came on March 16, 2026, from Vice Chancellor Lori W. Will at the Delaware Court of Chancery. It was a clear win for the Unknown Worlds founders.

“Krafton breached the EPA [Equity Purchase Agreement] by terminating the key employees without valid cause and by improperly seizing operational control of Unknown Worlds,” the ruling states.

The Delaware Court of Chancery broke the case into two parts. The first covers Krafton’s interference in the Subnautica 2 early access release date and control of the studio, and the second will determine whether Krafton’s actions wrongfully impaired the earnout.

The Phase One ruling accomplished several things:

The judge acknowledged that putting Gill back in charge “will cause tension with the parent company given the obvious bad blood between the parties.” But that “does not excuse a material breach of contract.”

Ted Gill Reinstated as Unknown Worlds CEO

Ted Gill was ordered reinstated as CEO of Unknown Worlds with full operational authority over the studio and Subnautica 2’s release. “Edward Gill is hereby reinstated as CEO of Unknown Worlds, and his period of operational control under Section 2.7(f) of the EPA will be extended by the time that elapsed between his wrongful termination and his restoration.”

“Krafton is enjoined from circumventing section 2.7(f) or impeding Gill’s authority over the early access launch of Subnautica 2 and must immediately restore his access to the Steam platform.”

The judge specifically noted the damage Krafton’s interim leadership caused. The judge said Unknown Worlds itself would suffer “palpable” harm without reinstatement: “Unknown Worlds is being run by a part-time CEO who manages another studio and had never played Subnautica before his appointment. Key staff members have quit.”

That interim CEO was Steve Papoutsis, a former Striking Distance Studios head. After taking charge of the studio, Papoutsis said Subnautica 2 would be launching into early access release in May. But according to the founders’ legal team, Papoutsis no longer had authority to make that announcement.

• Gill reinstated: March 16, 2026
• Steam access restored immediately
• Operational authority over all Unknown Worlds decisions
• Krafton prohibited from interfering

Key Takeaway: The court did not just rule in the founders’ favor on paper; it physically restored Ted Gill to power, gave him control of the game’s release, and told Krafton to back off.

Subnautica 2 Early Access Release and the Lawsuit

Subnautica 2 launched in Early Access on May 14, 2026, on Steam, after months of legal chaos over who controlled the release date. A May 2026 release window was confirmed a day after the judge ordered that Ted Gill was to be reinstated as Unknown Worlds CEO.

The timing of the launch was itself a flashpoint. After Gill’s reinstatement, outgoing interim CEO Papoutsis announced a May launch date. But according to the founders’ lawyers, Papoutsis no longer had the power to make that announcement, and they claimed Krafton had “intentionally leaked” his letter to staff.

The contempt motion that followed was eventually withdrawn in April 2026. The game still launched on May 14 as planned.

The game saw not only critical success but commercial success too, selling two million copies in its first 24 hours.

The launch was a vindication for the fired founders. The game they built was ready. The delays were not about quality.

Subnautica 2 Sales and the Earnout Trigger

Subnautica 2’s commercial performance appears to have triggered the maximum $250 million earnout payment. According to Alinea Analytics, the underwater survival game generated over $100 million in just a week, easily establishing Subnautica 2 as one of 2026’s most commercially successful games.

Subnautica 2 has already sold 4 million copies since it came to Steam on May 14. At $30 a copy, subtracting Valve’s 30 percent platform fee, that’s around $85 million in potential revenue for this month alone.

The deal states that every time Unknown Worlds’ monthly revenue reaches above $69.8 million, Krafton has to pay $3.12 for every dollar made, up to a maximum of $250 million. Alinea Analytics estimates that Subnautica 2 has now made around $100 million in revenue so far, smashing through that target.

Subnautica 2 generated $100 million by itself in just the first week, becoming the fastest-selling Steam game of 2026.

Krafton Breach of Contract Ruling

The court explicitly found that Krafton breached its Equity Purchase Agreement with Unknown Worlds. The court found that Krafton breached the Equity Purchase Agreement (EPA) by terminating the three key employees without contractual cause and by usurping their bargained-for operational control, including authority over Subnautica 2’s launch.

Krafton tried multiple defenses. None worked.

The publisher had originally claimed Gill and the other cofounders were fired for failing to get Subnautica 2 ready for a timely launch. It later switched to arguing that the cofounders had unknowingly been working on other projects and tried to steal unauthorized materials. The court rejected both claims.

Vice Chancellor Will largely affirmed the three executives’ retelling of the events, specifically that Krafton essentially made up its reasons for their dismissal to avoid the payout.

The ruling covers several distinct breach findings:

• Termination of Key Employees without valid contractual cause
• Improper seizure of operational control
• Interference with Subnautica 2’s early access release schedule
• Violation of the operational control provisions in Section 2.7(f) of the EPA

Krafton head of corporate development Maria Park had told Gill that Krafton had “no concerns” about Cleveland and McGuire’s role changes. That internal communication proved damaging to Krafton’s claim that the founders had abandoned their roles.

Key Takeaway: Krafton’s own internal communications, including statements from its corporate development head, contradicted every defense the company put forward at trial.

Subnautica Lawsuit Phase Two and Damages

Phase Two of the lawsuit is the part that still has teeth. The second phase will determine whether Krafton’s actions wrongfully impaired the earnout.

The Phase One ruling restored Gill and extended the earnout period. But Phase Two could cost Krafton even more. If Krafton is found to have done the latter, Gill, McGuire, and Cleveland will be awarded damages on top of the opportunity to still achieve the $250 million payout.

That is a critical distinction. The $250 million earnout is the contractual bonus. Phase Two damages would be additional money on top of that.

These damages could cover:

• Lost earnings during the period of wrongful termination
• Harm to the game’s commercial prospects caused by delays
• Reputational damage to the founders
• Legal fees and litigation costs
• Punitive damages if the court finds bad faith (which it already strongly suggested)

Litigation from the lawsuit pertaining to damages from the firings remains pending. The court will still have to decide as part of “phase two” what monetary damages if any have resulted from the entire chaotic affair.

No date has been set for Phase Two proceedings as of June 2026. Given how much has already been decided, this phase could be resolved through negotiation rather than trial.

What the Subnautica Lawsuit Means for Gaming

This case sets a strong precedent for developer rights in post-acquisition disputes. The case has drawn attention from labor attorneys across the gaming industry who see it as a potential precedent for how courts handle post-acquisition firings in creative industries.

Game developers often have far fewer legal protections than the public assumes. Many sign away significant rights as part of acquisition deals, believing in good faith that promised creative autonomy clauses will hold.

The Unknown Worlds founders won because their contract was tightly drafted. Their “Key Employee” protections and operational control provisions held up under scrutiny. The opinion provides important guidance on drafting and enforcing tightly drafted “for cause” definitions for key employees and the limits of post-closing “takeover” tactics.

For studios considering acquisition offers, the takeaways are clear:

• Strong earnout protections matter and can be enforced
• “For cause” termination clauses need precise, narrow definitions
• Courts will look at the acquiring company’s internal communications
• Using AI chatbots to plan contract avoidance strategies will not impress a judge
• Delaware courts take post-acquisition operational control agreements seriously

The case also sends a message to large publishers. You cannot buy a studio, promise the founders a performance bonus, then fire them when it looks like they will earn it.

Could Krafton Appeal the Subnautica Lawsuit Ruling

Krafton has signaled disagreement with the ruling but has not yet confirmed an appeal. “While we respectfully disagree with today’s ruling, we are evaluating our options as we determine our path forward,” Krafton said in a statement.

Cases tried in the Delaware Court of Chancery may be appealed to the Delaware State Supreme Court. That is the next logical step if Krafton chooses to fight.

However, several factors work against an appeal:

• The factual findings were overwhelmingly against Krafton
• The judge’s opinion was detailed and well-supported
• Subnautica 2 has already launched and triggered the earnout
• An appeal would generate more negative publicity
• Krafton has reportedly already agreed to pay the $250M bonus

The practical reality is that Subnautica 2’s success has made the earnout a done deal. Appealing the Phase One ruling while simultaneously paying the earnout would be legally awkward and strategically pointless.

In the end, Gill and co. seem to have achieved a total victory over Krafton. Ultimately, Krafton still owns Unknown Worlds, so it remains to be seen what the two companies’ working relationship will be like in the future.

Key Takeaway: While Krafton technically can appeal, the game’s massive commercial success has made the earnout payout a practical certainty, which removes most of the financial incentive to keep fighting.
