Mine scrap, build aircraft and tanks, then capture the uplinks before the other army does. Battle Drones is Simon Willison's browser strategy game, developed through repeated Claude-assisted iterations.

His October 20 build account traces its changes from a rough 2D prototype to 3D battles, new maps and multiplayer experiments. The project began in July; this is a recent account and update, not a claim that it was made in one prompt this week.
