The full story

Infinite Night is a Vampire Survivors-style dark fantasy action RPG on Steam with three characters, 24 weapons and seven languages. Its maker, a backend developer with no game development experience, wrote design documents while Claude Code wrote all the code, working directly in the Unity Editor through Unity MCP.

It wasn't quick: when Claude misread what was wanted it produced completely wrong code, and debugging took about half the development time. In a follow-up post the maker said most players quit after about ten minutes, and that they had since rebuilt almost every part of the game to fix it.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
