edit: It has come to light that without a server running GV script it is possible to cheat with NO detection at all.
Hell, i'm going to post it here so that all the publics get ruined. Maybe IW will get of their arses and fix the biggest exploit in cod history, it has been in since 1.1.
Wack that in console and you can use any ingame built console cheat.
Fixed by the community before IW even started work on it.
My hatred for public servers are ongoing, IW don't care untill it affects their profits.
