About OpenNox

OpenNox is an open-source community collaboration project that extends the Nox engine. It is an unofficial project with no direct affiliation with Electronic Arts Inc. or the Nox brand. Its stated purposes are preservation, modding and compatibility. According to the project, OpenNox supports all vanilla Nox features, and users should be able to complete the campaign and play online. Problems can be reported by opening an issue.

The project offers release builds, which are made from the dev branch, and nightly builds, which are automatically built from the dev branch on each commit. Nightly builds contain the latest merged features but are not considered stable. The project says they should be used only for active playtesting. The project does not include assets, texts, artwork or other media from the original game, and it encourages users to legally own the original game. Source code is licensed under the GNU General Public License version 3, unless stated otherwise.
