Ok, for the old people here is the instruction how to find the servers
:
Depending on how often Epic changes the menu layout this may also change, but right now you can do it this way:
1.) When the game is started, click on "Find a Match"
2.) Choose [Internet] Indivual Servers.
3.) And here they are! 4 indivual servers at the moment. Depending on how the Hub System develops we may also set up one in the future.
Please note that these are standard servers right now without any custom maps or custom addons.
