Server is down right now waiting for mod update but if you are looking for a sorta hardcore server come join us. Server has no 3rd person, x4 thrusters, earths gravity well is 300km till zero g, planets are spread out as well, earth to mars is like 5000km, we are running the lock and loaded version of OI, we are a pvp server but everyone is rather friendly and doesnt outright attack anyone else

I made one search up bobtopia
