GTA 6’s Project ROME Has Never Looked More Certain Amid New Rockstar Release
A new move from Rockstar Games is fueling strong speculation that the company is laying the groundwork for a revolutionary modding system in Grand Theft Auto VI. The potential release of the popular modding framework FiveM on Steam is being seen as a clear step toward the long-rumored “Project ROME.”

FiveM, which allows players to create and join customized role-playing and modded servers for Grand Theft Auto V, has historically been a community-run project. Its anticipated arrival on Steam as an official, streamlined download points to Rockstar’s deepening commitment to supporting and formalizing the modding ecosystem.
This action provides the strongest evidence yet for the existence of “Project ROME.” Industry rumors suggest ROME stands for “Rockstar Online Modding Engine.” It is believed to be a suite of official, user-friendly tools designed to let creators build custom missions, game modes, and entire experiences within GTA VI’s world.
The vision is to transform GTA 6 from a single game into a persistent platform, similar to Fortnite Creative or Roblox, but for a more mature audience. This would enable a vast library of user-generated content (UGC) directly within the official game environment.
Rockstar’s strategic interest in this space is not new. In 2023, the company acquired Cfx.re, the collective behind FiveM. This move signaled a major shift from Rockstar’s historically cautious stance on mods toward one of active endorsement and integration.
Industry analysts believe this is a calculated strategy to capture the creator economy. By providing official tools, Rockstar can foster a safe, governed, and financially sustainable ecosystem of custom content for GTA VI, potentially creating a new revenue stream and extending the game’s lifespan indefinitely.
A significant hurdle remains the official release schedule. Rockstar has not yet announced a PC version of GTA VI, which is where such modding tools would naturally debut. Based on the company’s history, a PC port is expected a year or more after the console launch in late 2026.
