A 192 GB archive that circulated publicly in September 2026 has been attributed, without official confirmation, to the breach suffered by Rockstar Games in 2022. Among the materials allegedly included in the package are very early blockouts and geometry for Leonida, linked to GTA VI development between 2014 and 2015.

Reports about the content claim that this prototype could be loaded into GTA V on PC. That does not mean it was a playable version of GTA VI: the available description points to planning materials and terrain testing carried out in the previous game's technical environment.

According to claims tied to the archive, the version featured underdeveloped terrain, main roads, and few recognizable areas. There are also mentions of satellite imagery and Google Street View data being used during the creation of the setting, but these elements have not been authenticated by Rockstar Games or Take-Two Interactive.

As an alleged pre-production stage, the material does not establish Leonida's final size, allow for a direct comparison with Los Santos, or determine which regions will be in GTA VI. The presence, absence, labels, and layouts seen in this prototype should not be interpreted as confirmation of content in the final game.

The package is also linked to discarded GTA V files, including references to a Liberty City expansion, content called Agent Trevor, and alternate dialogue. These claims likewise remain without public validation from the companies responsible.
