Spoilers for Major Upcoming Games Made Public in Achievements Leak

Full account

A large batch of achievement lists for unreleased and even unannounced video games has been published online, apparently after a fault in Steam's backend systems exposed data that should have remained private. The material surfaced overnight on sites that catalogue trophies and achievements, including Exophase and SteamDB, revealing plot details and content for a string of high-profile titles before their makers had chosen to disclose them. Chief among the exposed games are Persona 6 and Kingdom Hearts 4, both long-awaited sequels with no confirmed release date, meaning fans now face the prospect of avoiding spoilers for well over a year.

Accounts of how the leak occurred differ slightly in detail but agree on the likely cause: an error on Valve's part rather than any deliberate hack. One outlet suggested Steam's storefront had suffered a glitch that pushed achievement data live prematurely, noting that Exophase, which normally mirrors trophy lists once they officially appear on the PlayStation and Xbox storefronts, does not typically obtain information through unauthorised means. This was corroborated more directly by Exophase's owner, known as X3sphere, who told the community forum ResetEra that the episode looked like a 'possible screw up on Valve's end' after the Steam API began surfacing achievement lists that ought to have stayed hidden, including for titles with no public name attached.

The scale of what leaked is considerable. Alongside Persona 6 and Kingdom Hearts 4, achievement data emerged for Persona 4 Revival, Fable, Final Fantasy Resonance, Judas, Kena: Scars of Kosmora, Metro 2039 and Stranger Than Heaven. More strikingly, the breach also touched games that have never been officially announced. Reports point to an apparent Walking Dead collection from Telltale Games and a new entry in the Tetris franchise, while a list compiled by a Reddit user identified more than a dozen further unrevealed projects, among them a possible Sea of Thieves spin-off, and titles seemingly tied to Twin Peaks, Candy Crush, Sonic and Shrek.

Caveats accompanied much of the coverage. Not every item on the leaked lists appears genuine or reliable: a supposed Balatro-branded game was disowned by that title's creator, Localthunk, who said it had no connection to him or the original, and a listing for Toem 2 as 'unannounced' was inaccurate, since that sequel had already been made public. Journalists covering the story have generally declined to detail the specific spoilers involved, instead pointing readers elsewhere, and have noted a precedent in the trophy list for a Prince of Persia: The Sands of Time remake that leaked years before that project was ultimately cancelled. Valve, along with the developers and publishers of the affected games, had not issued any official comment at the time of the initial reports, though at least one outlet said it had sought a response.
