I built Bone Rush: City Tails in Unity using Claude Opus.

Instead of treating AI like a simple autocomplete tool, I used Opus across the actual production loop in Unity—architecting the street-runner systems, writing custom lighting and sky shaders, building procedural UI screens, and iterating on camera feel and dog animations step by step.

Game development is going to change dramatically over the next few years. We are still early, and shipping a real game still takes clear direction, taste, and relentless testing—but you can already see the shift happening right in front of us.

Here is a full developer walkthrough of how the world and systems come together in motion.

(Note: We paired Opus's Unity engineering with licensed external art and audio assets, and used Google Carbon to assemble and voice this walkthrough video.)
