You Can Actually Play This AI-Generated Version of Quake II Right Now

Microsoft has developed an innovative tech demo featuring an AI-generated version of Quake II, a classic first-person shooter originally released in 1997. They used their Muse AI tool, which was showcased earlier in 2025 as something that can make game visuals and simulate gameplay. The demo represents an evolution of this technology, showcasing a real-time, playable version of Quake II where every frame is generated on the fly by the AI.

The Muse tool, built with help from Ninja Theory (a team that works with Xbox), was taught using Quake II info to bring the game back to life. Unlike regular games that use ready-made pictures and set instructions, this AI version makes the game world, the looks, and even how you play all on its own, right as you go. It runs at a size of 640 x 360 on the screen—not huge compared to today’s games, but a lot better than earlier AI game tests, like one called WHAM-1.6B that was only 300 x 180.

You can try this AI-made Quake II yourself on a website called Microsoft’s Copilot Labs, right in your browser. Teaching the AI to do this took just over a week, which is way faster than the seven years it took for older versions. That speed shows how much Microsoft’s AI work is improving, especially for games.

This test is part of Microsoft’s bigger plan to use AI in gaming, starting with Muse, which first made little game clips for titles like Bleeding Edge. It’s still a work in progress, but it gives you an idea of what AI could do later—like quickly testing new games, saving old ones, or even making totally new games from scratch. Just so you know, the visuals and gameplay still feel a bit rough compared to today’s fancy games, since this tech is still pretty new.
