# GunZRs: a Rust reimplementation of GunZ: The Duel

> A Rust/Bevy port reads GunZ: The Duel files from the user's installation and provides native releases, browser build tooling, screenshots and a documented REA/Ghidra investigation framework. Its LAN protocol and inferred movement behavior remain distinct from retail-server compatibility and proven gameplay parity.

## Requirements & limits

- **Prerequisites:** Requires the user's GunZ: The Duel installation; no original game files are included. Native downloads target Linux/Windows, with Linux builds requiring the documented system libraries; WebGPU needs localhost or HTTPS and packs built from the user's data.
- **Attribution:** The README documents REA/Ghidra use for static questions about retail files.
- **Limits:** LAN uses the port's own protocol and does not connect to retail servers; several round/quest/Blitzkrieg modes are not played over LAN. Movement constants and some content choices are inferred.
- **License:** The project says gameplay has been exercised on Linux. Code is Apache-2.0, bundled fonts retain OFL terms, and original game files remain separately owned.
