The full story

Arena Game is a real-time 3D multiplayer strategy game in the browser, inspired by the Precinct Assault mode of the PlayStation game Future Cop: LAPD. The author wanted to see how far Claude could go without them writing a single line of code. You can play against others or against an AI to practise.

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.
