What Is the Subnautica 2 Developer Payout Lawsuit?

The Subnautica 2 Developer Payout is the $250 million judgment awarded to the founders of Unknown Worlds Entertainment in their lawsuit against publisher Krafton Inc. The problem it solved was Krafton's alleged breach of a profit-sharing agreement for the 2021 game Subnautica: Below Zero. The case is primarily known for Krafton CEO C.H. Kim's failed attempt to use ChatGPT to generate a legal argument defending the company's financial restructuring.

The $250 million payout ordered in the Krafton lawsuit represents one of the largest profit-sharing judgments in video game history, directly tied to the defendants' attempt to use generative AI to circumvent legal obligations.

How Did Krafton Attempt to Avoid the $250 Million Payout?

Krafton attempted to avoid the $250 million payout by creating a mobile submarine game designed to absorb revenue that would otherwise have been shared with the Unknown Worlds founders. According to the lawsuit, Krafton restructured its financial accounting to divert profits away from the specific contract pool owed to the developers under the profit-sharing clause.

The defensive strategy took an unusual turn when Krafton CEO C.H. Kim submitted a letter to the court that was drafted with the assistance of ChatGPT. The letter argued that Krafton’s financial maneuvers were standard industry practice and that no bad faith was intended in structuring the payments.

"The suggestion that ChatGPT, a program which expressly states it cannot provide legal advice, could serve as an adequate substitute for the professional conduct required of counsel in this matter is not well taken."

— Judge Chung, U.S. District Court, as reported by Kotaku

Krafton CEO C.H. Kim's reliance on ChatGPT to draft a legal response was explicitly rejected by the court as 'not well taken,' a factor that contributed to the final judgment against the publisher.

What Was the Legal Outcome for the Developers?

The legal outcome for the Subnautica developers was a judgment in their favor totaling approximately $250 million. The court found that Krafton had engaged in a bad faith restructuring of its finances to avoid paying the contractual profit share, and explicitly dismissed the ChatGPT-generated legal argument as unpersuasive.

The ruling validated the developers' claim that the mobile game project was a deliberate attempt to circumvent the profit-sharing clause. Following the judgment, Krafton was ordered to pay the full amount owed. The developers are currently proceeding with the development of Subnautica 2 under the Krafton umbrella, despite the history of litigation.

The court’s explicit rejection of the ChatGPT-generated legal argument set a precedent for the admissibility and persuasive weight of AI-generated correspondence in federal litigation.

Who Is This Ruling Most Relevant For?

This ruling is most relevant for video game developers, corporate legal teams, and executives negotiating contingent compensation agreements. The case establishes clear legal consequences for attempting to use generative AI tools to circumvent contractual financial obligations and legal procedures.

It serves as a cautionary example for technology executives who might consider using AI chatbots to draft legal documents or formulate litigation strategy without human attorney oversight.
