Steam achievement leak exposes unannounced PC games, Persona 6 spoilers

A third-party site appears to have leaked Steam achievements for a large batch of upcoming PC games, according to posts on r/pcgaming. The leaked list reportedly includes Persona 6, Kingdom Hearts 4, Ace Combat 8, Judas, and Tomb Raider: Legacy of Atlantis, along with titles that have not been announced at all.

The Persona 6 leak has drawn particular attention because its achievement text reportedly reveals story spoilers. The two threads surfaced within hours of each other on the same subreddit, with the broader leak post arriving after the Persona 6-specific one.

Steam achievement databases are populated from data publishers upload ahead of release, which makes them a recurring source of early reveals. The scope here is wider than typical single-title leaks, spanning multiple publishers and franchises at once, and the inclusion of unannounced games suggests the data may have come from a bulk upload or a compromised partner feed.

Neither Valve nor the affected publishers have commented publicly. The authenticity of the leaked achievement lists has not been independently verified.
