AI agent ran 12-hour experiments to build SlapFight, a fighting game where chat talks and AI throws hands

msg · x · 2026-09-08

A developer gave an AI agent (astra) access to fal's h3 director and asked it to create a fun fighting game — the agent ran experiments for over 12 hours and the result, SlapFight (slopfight.live), is nearly ready for playtesting.

The concept: one arena, two sides, the crowd calls the shots — chat talks trash and AI-controlled fighters brawl. Users can sign in to create fighters, write moves, and keep fight cards. The announcement montage was itself generated by another astra agent from the footage created during the experiments.
