Uebergame-dedicated.sh

#/bin/bash
# This script launches the dedicated server for Uebergame on Linux.
# For multiple servers just launch this script again, or copy, rename and modify it first.
# Dedicated servers offer the best performance, are best for running servers over long periods of time
# and the host does not have to be in the game while hosting it, since the server runs in the background.
# Dedicated servers are also necessary, if you want to run the game servers on internet servers.
