I rebuilt Dune II in three.js with Claude Code: 2 sessions, 2.5 hours, 4 bugs it made along the way (playable demo)

Dune II was the first RTS I ever played, and Dune Legacy (the open-source engine) has been keeping it alive for years. I wanted it in the browser, in 3D, with the exact same mechanics. So I pointed Claude Code at the Dune Legacy source and let it work Demo: [https://crocone.github.io/dune-arrakis/](https://crocone.github.io/dune-arrakis/) (desktop browser, WebGL 2, sound starts after first click) Code: [https://github.com/crocone/dune-arrakis](https://github.com/crocone/dune-arrakis) (GPL, since it's a derivative of Dune Legacy) It's properly playable: I've been running full skirmishes and campaign missions in it, not just clicking around the menu. What's in it: * three campaigns (Atreides, Harkonnen, Ordos), 9 levels each, with mentat briefings * skirmish vs AI up to 6 players, 50 Dune Legacy maps or random ones * every Dune II unit and building, sandworms, spice blooms, friendly fire, the CHOAM starport * save/load, a mentat encyclopedia * voice-over and sound effects…
