Well since everyone here already knows i'm a cheater, might as well inform you of some really entertaining mods I had going on the other night.
One of my friends has a jtagged box, so we start up hardcore matches with his box. Basically, no one could knife anyone(this was great when a guy came up behind me and tried to knife me 3/4 times before i just turned around and shot him lol), reload animations cancelled, the enemies showed up red boxes through walls, the mini map was twice as big, and my steady aim crosshair was the size of a dot.
We just continually owned people until they quit every game :)
