Claude Opus 5 just built a full 3D FPS game in a single HTML file. No dependencies. No frameworks. Just raw code.
290 KB. 60 FPS. Zero external tools.
What's inside:
• 100% procedural gen — meshes, textures, UI, sound effects all coded from scratch using WebGL + Web Audio
• 4 weapons with ADS, recoil, reload animations, scope sway
• Sprint, double jump, mantling
• 10 AI enemies that flank, use cover, and call out positions
This isn't a tech demo. It's a flex on what long-context AI can synthesize in one shot.
No bundlers. No build tools. Just a browser and a single file that runs a tactical shooter.
If AI can compile game loops and graphics pipelines natively like this, we're watching the entire indie dev stack get rewritten in real time.
