No way!

One person built a Sekiro-style boss fight in just 10 days using AI.

Without having a professional game development background.

He used Codex for level design and character animations, Claude for environment building and combat effects, and Tripo AI for 3D assets.

He also used Unreal Engine, AccuRig and Niagara to bring everything together.

The model generation alone cost him around $70 in credits.
