Massive Valve Leak Reveals Achievements For Kingdom Hearts 4, Persona 6, And Dozens More Games

Achievement data for a huge number of upcoming Steam games briefly became public on September 8, and it wasn’t supposed to. Exophase, a site that tracks trophies and achievements across platforms, ended up scanning in achievement lists for titles that should have stayed locked down until closer to release, some of them not even announced yet.

How This Actually Happened

Exophase owner x3sphere addressed it directly on ResetEra: 

Seems like a possible screw up on Valve’s end, a bunch of games with achievements that should be private are accessible through the API right now and that’s why they got scanned into the site. I usually never see games without an actual name pop up with achievements, yet over the past hour or so a bunch have.”

When Exophase can’t find a game’s real name, it defaults to showing the Steam App ID instead, which is how so many unannounced titles ended up identifiable at all. Valve hasn’t issued any public statement on what happened.

The Marquee Names In The Leak

Some of the bigger names swept up in the exposure include Kingdom Hearts IV, whose achievement list reportedly reveals several of its Disney-themed worlds ahead of schedule, and Persona 6, alongside Persona 4 Revival, Dragon Ball Xenoverse 3, Attack on Titan 3, Deus Ex Remaster, Thief: The Dark Project, Tomb Raider: Legacy of Atlantis, Gears of War: E-Day, Silent Hill: Townfall, Control Resonant, Ace Combat 8, Squadron 42, Stranger Than Heaven, and most importantly, an unannounced Shrek 2 remaster.

This leak is comparable to the Nvidia GeForce leak back in 2021, which revealed many upcoming unannounced titles coming to PC.
