Quantum computing used in 'first commercial game development' — IBM simulator generated maps, characters, and graphics in C.L.A.Y. RPG

Game studio MiTale Ltd. is at Gamescom promoting a narrative-driven post-apocalyptic RPG dubbed C.L.A.Y. - The Last Redemption. You may well have heard the same or very similar descriptions of a new game before, but C.L.A.Y. stands out for its use of quantum computing techniques in the creation of game assets as well as for game narrative and procedural systems. MiTale worked with experts from IBM Quantum Computing and claims this is the “first commercial game on the market utilizing quantum computing in an immersive narrative experience.” Moreover, it reckons this is “the first step toward using real quantum hardware in games to accelerate complex tasks in a manner similar to a GPU,” which is rather bold.

The official game page on Steam (linked above) doesn’t mention quantum computing, but perhaps it hasn’t been updated with details from this Gamescom announcement, or kept up-to-date with the game development process. A little bit of investigation reveals that C.L.A.Y.’s development seems to have spanned at least six years so far. We’ve been emailed a fuller statement about MiTale’s exploration of quantum games, and there is some more public information about MiTale’s IBM Quantum collaborations on the game’s Gamescom 2026 press kit.
