A technical glitch on Valve's Steam backend has exposed achievement lists for several major upcoming titles. This leak risks spoiling key story elements for players waiting for Persona 6, Kingdom Hearts IV, Thief: The Dark Project Remastered, and Squadron 42. Fans of these franchises should avoid achievement tracking sites until Valve resolves the data exposure.
Backend glitch reveals achievement data for major upcoming titles
The exposed data came from Exophase, a third-party achievement tracking service that pulls directly from Steam's backend. PC Gamer reported that the site retrieved the full achievement lists for the affected games. This access reveals narrative details that developers intended to keep hidden until official release.
The leak confirms Steam achievement data for Persona 6, Kingdom Hearts IV, and Thief: The Dark Project Remastered. It also seemingly confirms that Squadron 42, the Star Citizen spin-off, will launch on Steam. This title is not currently officially announced for the platform, making the data exposure particularly notable for PC gamers.
Valve has not yet issued a public statement regarding the cause or timeline for fixing the backend issue. The exposure highlights the vulnerability of pre-release game data stored on accessible public platforms. Players should exercise caution when viewing achievement progress for unannounced or unreleased titles.
