Why it's on the shelf
A complete first-person shooter delivered as one HTML file, with a bunker, wave enemies and a real gun loop. It is here as proof that a browser FPS does not need a download or an engine project; the page notes its CDN dependency on three.js r128.
How to play
WASD to move, mouse to look and fire, wheel to swap weapons. Click the frame once if the game needs keyboard focus, and use the fullscreen button above for a bigger view.
- wave defence
- multiple weapons
- mouse look
- reload

The build above is the shelf version. If you want it re-skinned for your brand, retuned for a different audience, or extended with new mechanics, we quote each job by hand and deliver a new standalone build.
- Re-skin — palette, sprites, audio, logo and end screen.
- Retune — difficulty curve, level length, controls, mobile layout.
- Extend — extra enemy types, modes, scoring, save data.
Paid exports and rebuilds are in development. Nothing is charged yet — browse and play the shelf while we finish the request desk.
