Can you get VAC banned from playing gamemodes like surf zombie etc on Counter Strike 1.6 Steam

No it is not a cheat client. All it is that server has a different mod set up and different maps nothing wrong with that. If you are looking for surf maps start with surf_ if you looking for zombie mod maps start with zm_ now if you do have cheats i must warn you that if their server is VAC secured and has like a shield near server name it is secured and if you cheat there you will be banned if you dont use any hacks good for you high five. If you do then you need to look for a server that doesnt have a shield near the name so its not secure you can use cheats there but how ever other players can report you cheating.
