You will get banned for it if you are caught/reported.
As far as i know VAC hasnt been fully implemented yet, but if caught you will get banned and your character will be deleted.
Regardless of what anyone says, DO NOT CHEAT ON RANKED GAMES!
Ofcourse, thats why i made myself a new account. Sadly i rarely see any games up on the open servers.
It is best not to push your luck. Plus, Cheat Happens does not approve of cheating in multiplayer.
For it to work in Open you have to be the Host, wont work if you join someone elses game.
I believe CH users are some of the few remaining gamers who do not feel the need to measure our **** size with 'achievements' and just want to play the damned game how we want.
Nicely put my friend we only want to playour games.
