Rockstar Updates Official Mod Guidelines Ahead of GTA 6: Single-Player Tolerated, Everything Else Goes Through Its Creator Platform
Rockstar has published a new version of its Mod Guidelines page dated September 10, covering its whole catalogue including GTA 6. PC single-player mods survive under strict conditions; story expansions, cross-title mashups, unofficial ports and any monetisation outside Rockstar's licensed Creator Platform are off-limits. Multiplayer modding is limited to the official Creator Platform (FiveM / RedM).
Overview
Two months before launch, Rockstar has turned years of inferred practice into a written rulebook. Its Community Resources page now carries an updated Mod Guidelines document dated September 10, applying across the studio's whole catalogue — GTA 6 included. Rockstar still does not endorse third-party mods; the support text notes that permission to mod "is not a license and does not imply endorsement, approval, or authorization" of an external project.
The page is organised into four sections: Respect Our Games, do not infringe Rockstar Games or third-party IP, do not harm the creator community, and do not engage in unauthorized or abusive monetization. The key takeaways:
Single-player survives, with hard edges. PC single-player mods remain tolerated provided they are strictly non-commercial, respect third-party IP, don't interfere with GTA Online or Rockstar's online services, and contain no cheat menus or tools aimed at multiplayer.
No story mods, no crossovers. The rules bar mods that "expand or modify Rockstar Games' official storylines, plots, missions, characters, or other elements of our established continuity", and forbid combining maps, locations, characters, storylines or assets "from one Rockstar Games title into another". That is the formal end of the long tradition of porting Liberty City or Vice City into a newer GTA. A companion rule — do not modify the games to run on consoles, hardware or platforms where Rockstar hasn't officially released them — also covers the native GTA V Switch port, the Wii / GameCube / 3DS builds and the recent iPhone effort.
Money runs through Rockstar's ecosystem. Multiplayer modding is "limited to Rockstar Games' official licensed Creator Platform or else as otherwise licensed directly by Rockstar Games". Rockstar owns Cfx.re and therefore FiveM and RedM, and the Creator Platform is described as the exclusive licensed home for monetisation; everything else must be strictly non-commercial. Mods that "engage in or promote conflict roleplay or military simulations depicting real-world armed organizations" are also prohibited.
Caveat: these are catalogue-wide rules. Rockstar has not said which GTA 6 mods will be allowed, and has not drawn a full line between single-player and online modding — so what GTA 6's mod scene actually looks like remains ⚠️ speculation.
