I wouldnt unlock all. Its obv. when someone check your CHistory
I wouldn't even use that hack. I am just saying that IF someone wanted to unlock everything they would need to press nearly every single key on the keyboard. I don't hack at all in Black Ops II because I don't want to take the slightest risk after I have been banned on MW2 and MW3. But I like to see what kind of hacks people make.
