Unencrypted preload files for Forza Horizon 6, totaling approximately 155 GB, were discovered on Steam. Users noted the presence of the data package shortly before it appeared on piracy platforms. Some players reported successfully launching the game, which is believed to be the final version or close to it, but without the day-one patch. Users who played the leaked version have received permanent hardware bans tied to specific PC components. The official release is scheduled for May 19, 2026, on PC and Xbox Series X|S, with a PlayStation 5 version to follow later. The Premium edition offers early access starting on May 15. The game is set in Japan and features over 550 vehicles, including Japanese classics and exclusive Forza Editions.
