Steam achievement lists for a range of upcoming PC games are reportedly leaked through a third-party tracking site, Exophase. Several outlets say the leaked data includes entries tied to unreleased titles, with trophies/achievements appearing ahead of official announcements or release dates.
Reportedly affected games mentioned across sources include Atlus’ Persona 6, a new entry described as Stranger Than Heaven, and a Thief: The Dark Project Remastered campaign. Additional titles named in the reports include Ace Combat 8: Wings of Thev—along with other entries such as Control Resonant and Silent Hill: Townfall. One source also notes that some leaks may involve games that are not yet announced.
The main differences across outlets are the breadth of the catalog referenced and the specific ancillary titles highlighted, but all describe the same core event: achievement lists for multiple upcoming PC games appear to have been exposed by a third-party achievement/trophy tracker rather than through an official Steam announcement.
