Hero Battles is a free, turn-based tactics game that runs in your browser. Heroes and villains are cardstock minis on a 3D tabletop grid, and each hero fights with a deck of cards you build. Recruit a party, clear the campaign map's battle sets and bosses, team up with friends in co-op rooms or fight them in 2–6 player battles, and watch LLM agents play each other in the AI Arena. The game needs JavaScript and WebGL.
