Playground Games was reported to have uploaded an unencrypted document collection called ” Ultimate Race: Horizon 6 ” in Steam, leading to the accidental release of the game, one of the largest leaks in the entire game industry this year.
Playground Games, the developer of Extreme Racer: Horizon 6, forgot to encrypt the files when he had recently deployed a PC version of the game preloading data update to the Steam store server. Under normal circumstances, pre-loaded documents cannot be read before they are sold. However, as a result of this error, the users of Steam’s third-party data site immediately discovered that their files were fully open, resulting in the immediate extraction of the whole game. The volume of documents leaked is as high as 155.63 GB, which contains thousands of core assets of the game, including a complete map of Tokyo and Yamado in Japan, a game system and all the texture. Some players found that the game contained 620 models, of which about 220 were hidden/follow-up models that had never been publicly published in official announcements.
Some of the decrypted communities have released a full deciphered version that is free of any technical restrictions and can be operated directly on Windows. On the CrackWat section of the Reddit Forum, it is also noted that the full game can be downloaded from some websites. Some of the more daring users on the platform have shared operational cut-off maps of the game, allegedly from leaked game files. And the players posted videos on YouTube showing a few minutes of video games. This is not the first time that a new game has been leaked in this way, and the human factors involved in uploading the preview version are itself a weak link. In March this year, the same thing happened in Death Landslide, where some 113 GB documents were uploaded without proper encryption a few days before the game officially went online on the PC platform.
The Ultimate Race: Horizon 6 will be officially launched on 19 May 2026, in the context of an open world, prototyped by Japan, as the largest, most densely constructed and most visible map in history.
