It depends on the engine the game is running on. If you get VAC banned on a source engine game, you will be banned from all source engine games on that account. In order to play the game again you need to make a new account and purchase the game. And to prevent this in the future read up on your info. No offense but the fact that you asked for a VAC Un-banner makes me think you have no idea what you are doing when you are downloading game hacks.
