by the way......... do you remeber (cod4 backlot invisible glitch)?????? in cod4 you must out of backlot and fall under for 20-60 seconds i think........ so again for noobs its not a hack its a glitch who have no advantages............
Its not fake, just pointless. You Get out of the map, after getting a certain distance out you become invisible, then you need to find a way back into the map. In this mode you can't kill anyone, its just for fun.
