GTA Multiverse Mod Lets You Travel Between Classic Titles

A Portal Between Worlds

While the GTA 6 hype machine keeps building toward the November 2026 launch, the modding community is busy doing something remarkable with the classic trilogy. A PC modder has managed to link GTA III, Vice City, and San Andreas together so that players can step through in-game portals and instantly find themselves in a different Rockstar title — with all three games running at the same time in the background.

This isn't a video feed or a screenshot trick. According to the mod's creator, each game is genuinely active beneath the portal effect, meaning the transition is as close to seamless as current technology allows.

How It Works

The technical lift here is significant. Running three separate GTA titles simultaneously and synchronising the portal transition between them requires careful memory and process management on the host PC. Key points from what the creator has shared:

• All three games (GTA III, Vice City, San Andreas) run as live processes at once
• Walking through a portal switches the active game in real time
• The other titles continue running in the background, ready for the next jump
• No pre-rendered video is involved — it is a genuine live switch

The mod has already inspired plenty of community jokes along the lines of "we got inter-GTA portals before GTA 6" — a light-hearted nod to the long wait for the next mainline entry.

What This Means for GTA Fans

Beyond the novelty, this kind of project is a testament to how deep PC modding talent runs in the GTA community. It also raises interesting questions about what the modding scene might achieve once GTA 6 eventually lands on PC. If creators are pulling off inter-game portals with decade-old titles, the possibilities for the next generation of tools could be extraordinary.
