A development team working on a new indie project called Codex Mortis has announced the launch of its first playable demo, drawing attention for an unusual reason. The studio claims the game is “the world’s first fully playable game created 100% through AI.

According to the documentation shared with media, Codex Mortis has been built entirely using AI algorithms and tools, with no traditional human led development process involved. The Steam page of the game makes no attempt to downplay this approach, instead placing it at the centre of the game’s identity.

The PR outreach, sent by an individual identifying themselves as Darek Crunchfest, confirms that the demo is now available to play on Steam. Codex Mortis is being developed by a studio called GROLAF, which is openly presenting the project as a fully AI driven experiment rather than a conventional game release.

“Death is your weapon. Mix five schools of dark magic, unleash devastating spell synergies, and raise undead armies in this necromantic bullet hell. Infinite builds, solo or co-op – embrace the forbidden and dominate. 100% AI-driven development.”
