Strogino CS Portal

Hello everyone, nice to meet you. I'd like to create a non-Steam server so other players from around the world can join. Is that possible? I'll be waiting for your response. Thanks in advance.

Yes.
You need a RevEMU for no-steam. https://bir3yk.net/forum/forum_15
And steamcmd for downloading game-server files. https://developer.valvesoftware.com/wiki/SteamCMD
