Key takeaways
- The mod operates far beyond simple texture swaps or visual illusions.
- The mod includes a nested structure where players start in San Andreas, launch GTA 3 on a large in-game screen, and then drive within GTA 3 to a secondary monitor to launch Vice City.
- DryxioGTA’s achievement arrives at a pivotal moment for Rockstar Games and the modding community.
- The release of this mod will likely inspire further experimentation with nested game structures and engine layering within the GTA modding community.
Modder DryxioGTA has successfully embedded the full engines of Grand Theft Auto III and Grand Theft Auto: Vice City directly into Grand Theft Auto: San Andreas, creating a playable game-within-a-game-within-a-game structure that runs three independent virtual worlds simultaneously. The technical feat, demonstrated in gameplay videos released in early February 2026, allows players to launch Vice City from inside GTA 3, which itself runs as a nested application within San Andreas. This represents a significant breakthrough in reverse-engineering and engine manipulation within the modding community.
A Technical Feat of Simultaneous Engines
The mod operates far beyond simple texture swaps or visual illusions. Each game runs as a separate, independent engine using the open-source re3 and reVC engines, all operating within a single San Andreas host process. Because the engines operate alongside one another in the same system memory, all three virtual worlds remain active simultaneously, allowing players to switch control between San Andreas, GTA 3, and Vice City using the F10 key while the other games continue running in the background.
DryxioGTA clarified that the games function as fully independent processes, meaning each embedded game retains its own story mode, save files, graphics settings, and independent gameplay. Players can apply separate mods to GTA 3 or Vice City without affecting the host San Andreas game, and each world maintains complete isolation from the others despite existing in the same memory space. This architectural approach preserves the original mechanics and design of each title while creating an unprecedented layering effect.
The “Inception” Nesting Mechanic Explained
The mod includes a nested structure where players start in San Andreas, launch GTA 3 on a large in-game screen, and then drive within GTA 3 to a secondary monitor to launch Vice City. This iteration allows Vice City to be rendered into a GTA 3 texture, while GTA 3 is rendered into a San Andreas texture, creating three layers of real-time, playable gameplay simultaneously. The mechanic transforms what would traditionally be a single-game experience into a recursive exploration of Rockstar’s classic trilogy.
To use the mod, users must possess the original files for both GTA 3 and GTA: Vice City from sources like Steam and copy specific executable files into the mod’s folder before placing the contents into the San Andreas directory. The mod is available for free download on LibertyCity.net, though users must manually locate their local game files through Steam’s “Browse local files” function to copy the necessary executables. This requirement ensures that users maintain legitimate access to the original game assets while experimenting with the modded version.

Implications for the Modding Landscape
DryxioGTA’s achievement arrives at a pivotal moment for Rockstar Games and the modding community. The accomplishment highlights the longevity and moddability of the RenderWare-era codebase, the engine used for GTA 3, Vice City, and San Andreas, demonstrating that even decades-old architecture can support cutting-edge creative experimentation. This technical breakthrough pushes the boundaries of what can be extracted and repurposed from Rockstar’s classic game engines.
The mod’s release coincides with a dramatic shift in Rockstar’s official stance toward modding. In January 2026, Rockstar Games launched the Cfx Marketplace, an official storefront allowing creators to sell mods for FiveM and RedM for the first time. This represents a complete reversal from Rockstar’s previous approach of shutting down modding platforms. The marketplace operates through Cfx.re, a team Rockstar acquired for approximately $20 million in August 2023, and already features over 314 products at launch, signaling the company’s newfound commitment to supporting the modding ecosystem.
Distinguishing From Prior Integration Efforts
While DryxioGTA’s mod represents a technical engine port, it differs fundamentally from earlier map-integration mods like GTA Underground, which added cities from GTA 3, Vice City, Manhunt, and Bully into the San Andreas world as a single merged map. GTA Underground merged locations into one continuous world, whereas DryxioGTA’s mod keeps the games as separate, nested instances, preserving the original isolation and mechanics of each title. This distinction matters because it maintains the integrity of each game’s design philosophy while achieving unprecedented technical layering.
The RenderWare engine, which powered Rockstar’s early 2000s library, has proven remarkably resilient to both preservation and innovation efforts. The engine was widely used by Rockstar before the company switched to its proprietary RAGE engine for later titles like GTA 4 and GTA 5. DryxioGTA’s work demonstrates that the RenderWare codebase remains fertile ground for experimentation, even as the industry has moved toward newer technology.
What Comes Next for Triple-Nested Modding
The release of this mod will likely inspire further experimentation with nested game structures and engine layering within the GTA modding community. As Rockstar’s official Cfx Marketplace continues to expand and legitimize modding as a creative and commercial endeavor, projects like DryxioGTA’s may influence how the company approaches future support for complex, technically ambitious mods. The marketplace’s rapid growth to over 314 products suggests that creators now have stronger incentives to pursue innovative projects.
DryxioGTA’s achievement stands as a testament to the creative potential that emerges when talented modders gain access to well-documented, open-source engine rebuilds like re3 and reVC. The triple-nested structure demonstrates that the boundaries between separate games need not be absolute, opening possibilities for entirely new categories of mods that blur the lines between titles. As the modding community continues to evolve alongside Rockstar’s changing policies, projects like this will likely become benchmarks for what dedicated creators can accomplish with legacy codebases.
