Steam may have leaked more than a list of upcoming games. Achievement data for many unreleased PC titles became visible through a third party tracker, and some of those lists appear to include story details publishers never meant to show this early. If the data is real, Valve accidentally exposed roadmaps and spoilers in one pass.Trophy site Exophase pulled in Steam achievement schemas that were supposed to stay private. Exophase owner x3sphere said it looks like a Valve-side mistake: games whose achievements should have been locked behind the API were suddenly readable, so scanners ingested them. Achievement names often mark bosses, worlds, romance flags, and ending beats. Once those strings are public, embargoes are already broken.

Persona 6, Kingdom Hearts IV, and Other Big Titles

Persona 6 is the sharpest example. Trackers say its list includes unannounced story information, including an organization called Hex, a Yokohama setting, and named case locations. Persona 4 Revival appeared in the same wave. Kingdom Hearts IV is also in the scrape, with achievements that appear to name worlds not yet revealed. Ace Combat 8: Wings of Theve, Judas, Control Resonant, Deus Ex Remastered, and Tomb Raider: Legacy of Atlantis are on the public lists too.

The rest of the dump is even messier. Roundups include Mega Man: Dual Override with unannounced Robot Masters, Metro 2039, Final Fantasy Resonance, Horizon Hunters Gathering, Clive Barker’s Hellraiser: Revival, Minecraft Dungeons II, Dragon Ball Xenoverse 3, Gears of War: E-Day, and Silent Hill: Townfall. Some pages look like placeholders, including unannounced Nickelodeon, Walking Dead, Tetris, and Twin Peaks entries.

Why This Could Be Worse Than the Nvidia Leak

Comparisons to the 2021 Nvidia GeForce NOW leak keep coming up. That incident mostly exposed speculative titles. This one, if genuine, exposes the checklist behind those titles. A name on an internal spreadsheet is a rumor. A full achievement list can read like a synopsis.

Two stranger reads are still unconfirmed. Some users think the scrape points to a new Balatro project. Others say Thief: The Dark Project Remastered includes strings that could refer to a campaign called The Tarnished Mirror. Those may be leftovers or dummy labels. They still show how wide the leak looks from the outside.

Treat the Lists With Caution

Steam partners often seed achievements months before a reveal. Names change, worlds get cut, and test trophies exist for backend checks. Valve has not issued a detailed public explanation yet. Even so, indexed achievement copy is hard to put back in the box. If you want to go in clean on Persona 6, Kingdom Hearts IV, or the other listed sequels, stay off trophy databases for now.
