If COD is your only reason to "de-mod"...DONT DO IT! ARE YOU NUTS!?!...wait, not fair, let me explain, at least, in my opinion ,why you shouldn't. Yes COD is a great game, but if you own the last 2 or 3 like I do...then it's kind-a-like the same dog, with a different collar. Sure you'll have fun getting to prestige and killing a few noobs along the way, and you'll wonder what the best load out is, and even Youtube the best hiding spots...but then when you're done...that's pretty much all youll have...COD....or any new few games you would want to buy. I personally think you should not give up a very valuable one-of-a-kind hacked system, for a very-easily-findable-on-a-store-shelf-any-day-of-the-week system.
...BECAUSE I CAN RAISE HELL, AND BRING IT DOWN TOO!
