sniperwolfs right. there are invisible skins but u have to have them.. to see the other person with them on. if u dont have them and their invisible... then reconnect its an error between client and server. it happens. i have never seen a headshot bot. invisiblity just talked about.. invulnerability. well theres only one way to fix that... learn to shoot. last the increased powered weapons? maybe the server might have mods added to the guns and you just dont know. i have never heard of this cheat before. and believe me.... i play 24/7, and have been playing ever since the demo came out... so please dont talk to me like im a fuckign idiot
