## Original post

This is absolutely insane. I just built a Halo-inspired FPS with AI that runs in the browser with 10vs10 multiplayer on @TesanaAI with 2 stellar maps.

Brasidas features Celestial Sanctum an ancient temple on a ring world and Beach Assault (old school Halo fans will love this one).  The Gunplay feels super tight and responsive and the multiplayer runs really smooth.

The game was built with Opus 5.5 & @threejs on Tesana with just a few prompts. It all runs perfectly in the browser with 10vs10 multiplayer.
