A leak for Forza Horizon 6 has reportedly emerged just days before its debut. Evidence suggests the PC files for this racing game were unintentionally exposed through Steam. Some reports indicate a playable version is now circulating on piracy sites after the files appeared online.

The breach traces back to the Steam storefront. Reddit users flagged the issue over the weekend, shortly before a playable build of Forza Horizon 6 reportedly hit piracy forums.

Online sources claim Playground Games uploaded unencrypted pre-download content to Steam, leading to a 155GB game build leak that was quickly detected on SteamDB.

Multiple users have shared screenshots and video footage said to originate from the leaked PC build.

Playground Games and Microsoft have yet to address the incident.

Forza Horizon 6 arrives on PC and Xbox Series S/X on May 19, though Premium edition pre-orders unlock early access starting May 15. PC players can access it via Steam and the Xbox app on Windows, with day-one support for Game Pass Ultimate and PC Game Pass. A PS5 release follows later this year.
