Having now played the campaign and worked my way to prestige level (did not go for it), I have to say that it is very frustrating that cheating is rampant

The campaign is your typical story driven experience, but for those of us who enjoy the campaigns it is very cool, with awesome action moment and an interesting story

Don't buy this crap unless you like playing campaign

Kevin Spacey is a monster and makes what would have already been an awesome campaign into a really REALLY awesome/cool campaign

But, I took the risk and quite frankly, I don't see what the fuss is about - both in multiplayer as well as single player campaign.
