Steam has suffered quite a massive leak. ResetEra’s owner, Exophase, has posted the achievement lists for several games. None of this should have been made public, since the titles in question haven’t been released yet.

Games such as Persona 6, Kingdom Hearts IV, Fable, Control Resonant, Clutch, Tomb Raider: Legacy of Atlantis, Kena: Scars of Kosmora, Metro 2039, Stuntman: Hollywood, and Stranger Than Heaven are among those affected. This appears to be the result of an error on Valve’s part.

Needless to say, these achievements contain spoilers related to the story and content of these games. The Gematsu website has compiled all these lists for anyone who would like to check them out.
