I tried 2.85 several months ago, but as Gunman said the ppl there only uses mpcheat commands and usually plays onl COOP matches, means playing against "bots". No one there is interested in "real" multiplayer games.
I tried playing 2.8.5 for a while, but I deleted it in the end. When you join a server and everyone is flying around and using unlimited ammo just ruins the game completely. It could be something really great if the hacks were turned off.
