      Xonotic is a free, fast-paced first-person shooter that works on
      Windows, macOS and Linux. The project is geared towards providing
      addictive arena shooter gameplay which is all spawned and driven
      by the community itself. Xonotic is a direct successor of the
      Nexuiz project with years of development between them, and it
      aims to become the best possible open-source FPS of its kind.
