FALLGUY is a stunt-rehearsal simulator. You upload a video or photo of a real location, and Gemini 4 Argon rebuilds it as a physics-ready, game-style 3D world, then checks it against the footage and refines it. You describe a stunt in plain English. Argon choreographs it, and a Unitree H1 humanoid performs it in MuJoCo while we trace the biomechanics: head G, HIC15, joint torques and impact forces. Argon then acts as the Assistant Stunt Director. It watches each take, reads the numbers and proposes a safer, better next take, so directors can test choreography changes in minutes with nobody at risk.
