I was stupid enough to activate the cheat/code on the computer on "Black Ops". This cheat/code will disable you to get the achievement. The cheat/code is: 3ARC INTEL. Don't put this code in the computer, because this will disable the achievement and
lead to frustration. I are going to contact microsoft, but I take this to the forum first.
Do someone have any solutions/ideas to get this achievement when you have activated it?
