You learn that a studio has died from LinkedIn now. On 16 September a run of farewell posts went up from people at Build A Rocket Boy, the Edinburgh studio Leslie Benzies founded after leaving Rockstar North, and by that evening Kotaku was reporting from sources familiar with the situation that the closure is permanent. The company has said nothing. It said nothing about the two previous rounds of cuts either.
So: reported, not announced. No filing, no statement, no list of names the way Polyarc published one when it shut on 11 September. What there is instead is a headcount that went from a reported 448 at the end of 2024 to 202 by the end of June this year, and then a Tuesday.
The game was the demo
Here is the part that matters to anyone who builds pipelines for a living. MindsEye was never the product. Everywhere was the product — a free-to-play Unreal Engine 5 platform, unveiled at Gamescom 2022, where players would author their own experiences out of a no-code toolkit called ARCadia and publish them as ARCs. MindsEye was the premium thing you were meant to find inside it. Proof that the tools could carry a AAA action game, made by the people who wrote the tools.
Building the demonstration and the thing being demonstrated with one team, at one time, is a specific kind of trap. Every content problem in the game becomes a feature request against the toolset. Every change to the toolset invalidates content that already shipped. The scheduling is circular by construction: the game cannot lock because the tools keep moving, and the tools cannot lock because they exist to serve a game nobody has locked. I have watched much smaller versions of this eat a year, on projects where the rig and the shots using the rig were being built at neighbouring desks. At the scale of an open world it is not recoverable by working weekends, which is roughly what the staff letter says they were asked to do instead.
MindsEye shipped in June 2025 and shipped badly. Then came the inversion. This year the studio folded the game back into the platform — Play.MindsEye became Arcadia, Build.MindsEye became Build.Arcadia, and the campaign turned into one piece of content inside a creation suite, alongside a permanent price cut. The demo had failed, so the demo was repurposed as the storefront.
Money was never the constraint
Benzies raised $110 million in 2022 on his reputation alone. Totals reported since disagree — $151 million in one count, north of $300 million in another, £233 million in a third — and the disagreement is itself worth noting, because it means nobody outside the company is confident how much went in. Whichever figure is right, it is more than most studios see in a decade.
Sega weighed ¥100 billion over five years at a version of the same idea and stopped, and its president was unusually blunt about why: the company had assumed it already had the technology to run a live service at that scale, and it did not. Sega found that out in a boardroom. Build A Rocket Boy found it out in public, across two launches and three rounds of layoffs.
What is on the record and what is not
Around a hundred developers signed an open letter last year alleging mismanagement and unbearable overtime in the four months before launch, and some took legal action. Co-CEO Mark Gerhard tied the game’s reception to what he called organised espionage and corporate sabotage — a claim that has never been tested anywhere it could be, and which a former developer publicly described as the CEO’s hate mail. Nothing about the sabotage allegation has been substantiated.
Unconfirmed as of today: the closure itself, the number of people cut on Tuesday, what happens to Arcadia’s servers, and whether anyone who bought MindsEye keeps access to it. That last one is the question worth asking loudest, because a creation platform that stops running takes every ARC built inside it with it.
Two hundred and two people were on that payroll ten weeks ago. Most of them were hired to build an engine-adjacent authoring toolchain, which is exactly the skill set the industry keeps saying it cannot find.
