When you play as much as I do you will see those cheats and without a doubt they exist. Ive emptied 3 clips into people before whilst they stand there and let me do it. Invisibilty comes about when people mess with the skins, if you dont have "force player models" box checked then people can appear invisible. Play a bit more and you will surely come accross at least one of these cheats, still dont believe me? check the message boards theyre full of questions about cheats. Glad you like the sight by the way
