a cheat that is yet to be banned is the equipment glitch on mw2. in order to do this you must have "one man army pro" and a tactical insertion. press triangle (or Y for xbox) when you have one man army pro on, and it will give you the option of changing classes. as you press X (or A for xbox) to change class press R2 (or RT for xbox) at the same time. you will then be able to shoot with what ever equipment that class has e.g Tactical insertion, claymore, semtex etc. you will come out of this glitch if you jump or sprint.
the best weapon is the ump silenced with claymore, sleight of hand pro,stopping power pro, and commando pro
