While the industry waits on GTA 6, a modder going by Dryxio built something the series never had: a multiverse spanning the first three 3D GTAs. The mod opens large portals between the worlds of Grand Theft Auto 3, Vice City and San Andreas — you can walk through them and even shoot from one game into another.
Why it is technically interesting
The striking part is not the effect but how it is done. According to the author, there is no video playing behind the portal and no captured window embedded in it: the second game is genuinely running in real time. Several processes live in memory at once, and the mod stitches their image and part of their game logic together so the transition looks continuous.
That is exactly why shooting through a portal works: both sides are live scenes, not a texture with a recording on it.
Why this matters beyond “a fun mod”
The story is a good illustration of what the modding scene around Rockstar’s older games is actually built from. Working with another process’s memory, hooking the renderer, synchronising two engines into one frame — that is the same toolkit behind any in-game overlay.
The difference is where you point it. In the single-player entries of 2001–2004, touching the process is a legitimate part of the culture: without it there would be no high resolutions, no vehicle mods and no community remasters. In online GTA 5 the same technique falls under the anti-cheat’s jurisdiction and Rockstar’s rules — and there it costs you an account.

What this means for players running software
- Single-player and online are different universes. Whatever you install in GTA 3, Vice City or San Andreas concerns nobody. Whatever you run next to GTA Online enters the protection’s field of view, and the consequences there are nothing alike.
- “It’s a mod” is not a defence. Rockstar has historically tolerated single-player modifications and reacted hard to any interference with online sessions, whatever it is called.
- Keep modding tools away from an online session. Injectors and overlays left in memory after a single-player run are the most common source of unexpected trouble.
Bottom line
Portals between Liberty City, Vice City and San Andreas are a fine reminder that the most inventive part of the GTA community lives in single-player, where experimenting carries no cost. Online does not offer that freedom, and it never will.
