Xonotic is a free first person shooter that is influenced by Quake series. The game is written in QuakeC which is compiled into bytecode and server have the ability to upload this bytecode to the client. This allows for total conversion mods that will work out-of-the-box. Here are my contributions to it.
These contributions were merged into the git
master branch and are available in the up-to-date version of Xonotic.
Better kill sound.
Give player some random weapons during spawn.
Makes traversing the map much easier.
Give newbies a chance to frag.
No more map control.
These contributions were not merged in Xonotic and require you to manually checkout their branch and compile yourself or wait for them to be merged in the future.
Standalone overkill weapons that can be used outside of Overkill mutator.
Kills other players with all weapons. One weapon at a time.
Asymmetric attack/defense gametype.
