A developer showcased a browser-based 3D first-person shooter tech demo built entirely via Vibe Coding. The game requires no installation or download, running straight from GitHub Pages with all graphics and audio generated procedally at runtime.
Tech Stack & Features:
- Built with Three.js (WebGPU renderer), Cannon.js physics, and Web Audio API.
- Features wave-based combat, elite enemies, a tactical HUD, and 100% procedural audio (music, ambience, spatialized sounds) without any MP3/WAV assets.
Development Process:
- Created in 2 days of non-continuous vibe coding. The developer leveraged multiple LLMs including GPT 5.6 (via Codex), Kimi K3, and DeepSeek v4 (via Cline) to generate the code.
