Realistic First-Person Island Survival Game

Actual gameplay footage of a photorealistic first-person open-world survival game built with three.js, set on a procedurally generated island, roughly 63 seconds long. The author had Opus 5.5 build it in Claude Code from a single short prompt, then had the model find reference photos on its own to push the realism further. A good reference for short videos showcasing game development demos or web 3D tech.
