3 Strickly speaking, there are no "mods" in Xonotic. However, sometimes the term "mods" is loosely used to refer to variations of the officially released game.
5 For example, there used to be an "[SMB mod pack](https://github.com/MarioSMB/modpack)" with experimental features that were not in the official game. The developer of SMB Mod Pack is Mario, who is in the Xonotic core development team.
7 Another "Xonotic mod", [ChaosEsque-Anthology](http://opengameart.org/forumtopic/chaosesque-anthology-opensourcefree-fps-standalone-mod-of-xonotic-released), based its code on the official Xonotic, but this project has no official connection to Xonotic.
