Rust community servers can be PvP, or PvE. Servers can hold from 50-200+ Players. Admins can have special permissions and are allowed certain things that non-Admins cannot do, such as ban or kick players. World chat is indeed World-wide chat, but voice chat through microphone (the 'v' button) is proximity based chat.
The only thing that RUST doesn't have is a Guild system.
Tumblin is running a server.
Hearthstone please!!!!!!!!!!!!!! Qqq
Rust is becoming a failed experiment. Too many people fighting with each other each time someone wakes up dead. I am shutting down my server before more problems arise. I believe eGO should focus more on DayZ than Rust atm.
