Dead Letter — editable browser project
A stylized browser zombie FPS with drawn scenery and geographic surroundings. Open /fps.html for the game; the root page is the accompanying map.
€29 + applicable tax. Download the source project and supplied browser build. This is a developer package: it requires a local development environment or web hosting, rather than a desktop installer.

Requirements and limitations
For all online features, deploy dist from this project root using Cloudflare Pages so its functions directory is included. For local API testing use a Cloudflare Pages development server with functions; Vite alone only serves the static app. The downloadable build is not a desktop executable.
AI-assisted code, text and graphics are disclosed. This is a source snapshot; exclusive ownership, domain names, seller accounts, hosting, ongoing updates and support services are not included. You may not resell the original proprietary source kit. Third-party licenses retain their own rights and conditions.
Credits and data
Three.js (MIT); cadastral data DGFiP/Etalab (Licence Ouverte 2.0); OpenStreetMap contributors (ODbL). Included zombie audio has its CC0 notice at public/assets/audio/zombie/CC0-LICENSE.txt. Data provenance is retained in README.md and public/data/world.json.
