Modder linked GTA: San Andreas with GTA III and GTA: Vice City via portals - you can shoot and run into other games

A tech enthusiast linked several 3D game worlds from the GTA franchise.

The author of the YouTube channel DryxioGTA continues to experiment with classic 3D Grand Theft Auto games. Recently, he created a "matryoshka doll" out of Rockstar Games' titles — launching one inside another and controlling events in the GTA III world from GTA: San Andreas.

Now DryxioGTA has taken everything to a new level — he installed several portals on Grove Street in Grand Theft Auto: San Andreas — one leads to the world of GTA: Vice City, another allows a peek into Liberty City from GTA III, and a third is connected to Las Venturas from San Andreas itself.

These are not "rectangles with overlaid video," but truly full-fledged portals. If desired, the main character Carl "CJ" Johnson can shoot into another world or escape into it — in which case, after a brief loading, the game will switch and the main character will change.

DryxioGTA showed that these portals can be spawned at any time. He clarified that GTA III, GTA: Vice City, and GTA: San Andreas simultaneously run within a single process; these "portals" work in real time. The project is built on modified re3/reVC, librw, and plugin-sdk.
