- Quick Answer: Forza Horizon 6 has reportedly suffered a major pre-release PC leak after Steam preload files were allegedly uploaded without proper encryption, allowing users to access and spread a playable offline build before launch. Reports claim some players are already exploring the game’s Japan-inspired map ahead of the official May 19 release, creating backlash among legitimate buyers and reigniting debates around Steam preload security, DRM, and piracy protection.
Forza Horizon 6 has reportedly suffered a major early leak on PC, with the full game allegedly appearing online more than a week before its official release.
The situation appears to have started after files connected to the Steam preload were made available without proper encryption, allowing users to access and extract the build before launch.
Instead of simply letting buyers download locked files ahead of release, the preload reportedly exposed a playable version of the game, which then began spreading through piracy communities and file-sharing sites.
The leak is especially damaging because Forza Horizon 6 is one of Xbox’s biggest releases of 2026. The game is scheduled to launch on May 19, while Premium Edition owners are supposed to receive early access on May 15.
Because of the leak, however, some players online are now claiming they have already been able to drive around the game’s Japan-inspired setting before legitimate buyers can officially play.
That has created an awkward situation where people who paid for the game, including those who paid extra for early access, may end up waiting behind users who accessed the leaked build illegally.
Are Players Really Already Racing Through Japan?
According to the reports being discussed online, the leaked files are roughly 155GB, which has led many to believe the build may contain most or all of the full game.

While the online side of Forza Horizon 6 is reportedly still blocked by server authentication, the offline portion appears to be what pirates are claiming to access.
Gameplay footage and comments about performance have already started circulating, with some users saying the game appears to run well on PC, although those claims should still be treated carefully until the official release version is available.
The suspected cause has also sparked wider criticism of how major publishers manage PC preloads. Normally, Steam preload files are encrypted so players can install the game early but cannot actually open or run it until the official release time.
In this case, the files were allegedly uploaded without that protection, which meant the preload system worked more like an accidental early release.
Online discussions have compared the incident to other recent PC leaks, including Death Stranding 2 and Pragmata, where preload or build-handling issues also reportedly allowed games to spread before launch.
Could DRM Like Denuvo Have Prevented This?
The situation has once again sparked debate over DRM protections, as some fans believe technologies like Denuvo could have helped contain the leak, though others point out that anti-piracy software means little if the wrong files are accidentally released.
Denuvo remains controversial because of player concerns about performance, ownership, and long-term access, but incidents like this show why publishers continue to consider stricter protection for major PC releases.
At the same time, the situation appears to stem more from issues surrounding build security and release management than piracy protection itself.
Legitimate buyers are understandably frustrated, especially those who pre-ordered Forza Horizon 6 or paid extra for the Premium Edition expecting early access, only for the leak to create the impression that unauthorized users are already driving through the game’s Japan-inspired world.
That does not mean the leaked version offers the full intended experience, though.
Forza Horizon games rely heavily on online features, seasonal events, live-service updates, community interaction, car sharing, online races, and progression systems that are usually tied to official servers.
A pirated offline build may let users drive around, but it likely cannot fully replicate the live Horizon experience.
At the time of writing, Microsoft and Playground Games have not publicly addressed the reported leak.
Until they do, much of the situation remains based on reports, SteamDB activity, piracy-community claims, and footage circulating online.
