WizzRust

WizzRust runs a network of European and Australian Rust worlds with group limits ranging from solo to six players. The EU Solo/Duo realm is the main connection, with a separate EU Solo world and a 2x Solo/Duo/Trio realm. The official site publishes real-time player counts, connection addresses, the map-wipe timetable and server rules. The EU worlds displayed 25, 15 and 9 players, respectively, when checked. Open Rust, press F1 and connect to the Solo/Duo address. Other worlds and their connection addresses can be found on the official server page.
