UTLauncher is a standalone application to join some UNOFFICIAL UT4 servers.
If you don't yet have UT, you will have to go to Unreal Tournament forums and get it there: https://forums.unrealtournament.com/showthread.php?12069
It is a playable pre-alpha so please know that many things are stubs and most things are subject to change.
Help as build the game by posting feedback on the forums!
How to use
Double click on a server to join. It will ask for UnrealTournament.exe (only once though) To join via editor, you need to setup editor paths in Settings and right click on server.
Source code: https://github.com/CodeCharmLtd/UTLauncher This works and builds on Linux as well
I appreciate starring the project on GitHub, you can also post issues there
