We have an AI-made RDR: 2-GTA V mashup before GTA VI!

Picture this: You’re playing RDR: 2 as Arthur Morgan, and for some reason, you want to see what Morgan would do in Los Santos. So your game, allows you to just type in a prompt, and boom, your surrounding slowly turns into that of downtown Los Santos, with yout your horse now trotting past sports cars and skyscrapers. No loading screens, no interruptions, just seamless, live world-switching powered by AI.

Sounds impossible, right? Not anymore. This isn’t a trailer for some blockbuster crossover, but a real playable demo made possible by the new wave of generative AI game engines. And at the heart of this revolution is Mirage 2 from Dynamics Lab, a tool that’s changing what it means to create, play, and shape your own game worlds.

Enter Mirage 2: The Generative World Engine

Just a month after introducing Mirage 1, Dynamics Lab is back with Mirage 2, the world’s first Generative World Engine. Unlike anything before it, Mirage 2 puts world-building, editing, and gameplay directly in your hands. And the best bit is that it’s all powered by language. Every player can now remix and rewrite their surroundings, mid-game, using just text prompts.

We already have AI tools to edit videos like a pro, using just text prompts. But designing entire game worlds? That's wild!

So yes, that wild west-meets-Los Santos mashup is not only possible, it’s the perfect showcase for what Mirage 2 can do. Here, the boundaries between game genres, settings, and even roles, player, creator, explorer, completely disappear. Want your cowboy to ride from dusty canyons into a bustling Cyberpunk metropolis of Night City? Mirage 2 makes it happen, all in the same continuous session.

Worlds That Listen, Change, and Play Back

At its core, Mirage 2 uses a neural simulator that predicts both visuals and game logic, rendering motion and handling interactions in a single, fluid loop. Upload a quick sketch or a favourite photo, and Mirage 2 will turn it into a full 3D playground with physics, materials, and a playable character. Every scene and action, whether it’s a wild west shootout or a Los Santos car chase, can morph instantly based on your prompts.

Latency clocks in at a snappy 200ms, making edits and movement feel natural. More impressive: the whole thing runs on a single consumer GPU, making it accessible for solo devs and indie teams alike.

Sharing, Collaboration, and the Future of Play

Mirage 2 isn’t tied to a single genre or a traditional asset pipeline. Your worlds are shareable, friends can jump in and play the universe you just created, tweaking it further with their own ideas. Got a crazy mashup in mind? Now you can build it, play it, and watch it evolve in real time.

There are some rough edges: certain actions can still feel a bit imprecise, and quick scene changes might cause the visuals to wobble. But the fact that this level of generative, live-editable gameplay exists, especially from a team of fewer than ten people, is honestly jaw-dropping.

Big names like Google are still keeping their AI-powered Veo-3 behind closed doors. Meanwhile, Dynamics Lab has Mirage 2 live and playable for anyone curious enough to try. If you want a glimpse of the future, where games become living canvases for your imagination, Mirage 2 is it.
