Vanish allows players with permission to become completely invisible. Players, turrets, helicopters, NPCs, etc. will not be able to see, hear, or touch you!
Note: While vanished, you can hear players but they will be unable to hear you. You are invisible to them and essentially do not exist to them. Even if they walk right through you they DO NOT know of your existence. With the exception of you making sounds such as shooting a gun, they will hear the bullet - hit...
