Battle Drones - a vibe coded RTS with audio-based multiplayer simonwillison.net

Simon Willison has released Battle Drones, a browser-based, mobile-friendly real-time strategy game built largely by Claude coding agents over 12 major iterations. Its new multiplayer mode synchronizes two nearby devices through audio, avoiding a game server; the game also features 3D units, random maps, several play modes and battles between AI agents.
