With so much debate surrounding the use of generative AI in video games, advertising a release as "the world’s first fully playable game created 100% through AI" might come across as a bold and risky marketing claim. This is the assertion made about Codex Mortis by a developer known as GROLAF. The trailer, filled with AI-generated glitches and oddities, almost seems purposely designed to look poor. The game itself does little to support the idea that AI can produce truly original ideas or visuals. So, are the creators of Codex Mortis genuine pioneers, or are they simply provoking outrage to drive engagement (for those interested in making games without coding headaches, check out our guides to the best game development software and laptops)? Codex Mortis is labeled a “necromantic survival bullet hell. ” A demo is available on Steam, and the developer has shared documentation explaining how the entire game—from text and artwork to music—was generated solely through AI tools and algorithms. According to its description, players must assemble a ‘death squad’ to battle demonic foes using spell combinations, either solo or in multiplayer co-op. The game includes three modes: Escape, Challenge, and Eternal. If it feels familiar, you’re not alone. Many have noted it seems like a mod of Luca Galante’s well-known Vampire Survivors. “The clearest case of AI just stealing from artists so far, ” one commenter wrote on YouTube. “This looks like a one-year-old randomly typing prompts into an AI generator, then a corrupt corporate game studio CEO’s five-year-old gave it the thumbs up.

Great contribution to the sloppy market!” another person posted. GROLAF likely anticipated these reactions. In fact, it seems the developer might even seek out controversy in an effort to become the world’s most disliked developer. Some speculate this approach aims to attract AI enthusiasts who might purchase the game simply to spite anti-AI critics. Others think it could be a tactic for a new developer to gain attention before creating a more polished title. You can find more details about the game on Steam. What’s your take—do you think the developer is deliberately courting controversy?
