Exophase, a service that tracks game achievements across platforms, displayed records tied to unreleased and unannounced PC projects in an exposure with no confirmed start date. The listings included Persona 6, Kingdom Hearts 4, Fable, and other titles, as first reported by GameSpot.
Some records appeared under Steam application IDs rather than recognizable game names. Several sets also contained placeholder text and looked incomplete, suggesting developers had uploaded work-in-progress entries to Steam.
Achievement records can spoil a game before launch
The exposed material reportedly included story-related information. Kingdom Hearts 4 entries also pointed to additional Disney-world details, potentially revealing content Square Enix has not publicly outlined.
Achievements often describe missions, bosses, locations, character milestones, and endings. Even an incomplete set can give players a rough outline of a game’s progression long before a publisher wants those details public.
Mike Bendel, Exophase’s owner who uses the name x3sphere online, attributed the exposure to a possible Valve Steam API privacy error. He said achievements that should have remained private appeared accessible through the API after achievement records were uploaded to Steam and scanned by Exophase.
Steam’s handling faces fresh scrutiny
The incident follows a separate recent disclosure involving roughly 13 terabytes of Steam-related material, including pre-release builds and prototypes. That collection reportedly covered games added to Steam between 2003 and 2013, with material connected to Spore, Call of Duty: Modern Warfare 4, and an early Portal 2 build.
For players, the immediate risk is spoilers around high-profile games that have yet to receive release dates. For studios, exposed development records can disrupt announcement plans and reveal internal naming, unfinished objectives, or content that may never ship.
Valve has not confirmed an API configuration or access-control error, and the authenticity of every listing and its connection to a specific game remain unverified. It is also unclear whether the projects are active, canceled, or represented by temporary internal identifiers, while the final content and release timing for Persona 6, Kingdom Hearts 4, and the other listed games remain unknown.
