Open-source licences
Last updated: 30 October 2026
1. What the download contains
The Wixtria AntiCheat download holds two zips for a Linux Counter-Strike 1.6 server: wixtria-plugin, which every server installs, and server-dependencies, which a server needs only when it lacks one of its components or runs an older one. Next to the Wixtria Gate and the Wixtria plugins, which are Wixtria's own proprietary software, they bundle the open-source components below. Every component except the engine ships unmodified, exactly as its authors released it, and its source is published in a public repository whose release mirrors the upstream files.

3. The Wixtria engine
The Wixtria engine is Wixtria's own build of ReHLDS, released under the MIT licence. Its source is not public. The ReHLDS licence texts ship with it in the download.
The ReHLDS source tree includes header files from the Valve Half-Life 1 SDK, and those files carry this notice:
