battledrones v14: Compass Rose, a four player map
Simon Willison used Claude Opus to add four-player multiplayer to his Battledrones game
“Add a new map for a four player battle - four way rotational symmetry, up to four AI players, works with the WebSocket non-audio based multiplayer mode so up to four human players can join (any spare slots use AI)”
Simon Willison released Battledrones v14, using a single Claude Opus prompt to generate a new four-player map called 'Compass Rose' and modify the WebSockets multiplayer code to support up to four simultaneous players. This is a hobbyist project showcase rather than a major industry signal. It illustrates AI-assisted iterative game development but has limited newsletter relevance beyond demonstrating LLM coding capabilities on a personal project.
