Not as good as it was supposed to be, Treyarch prove once again they are the weak point in the Cod franchise
I will end on a good note, there are some brilliant new bits brought in to the multiplayer experience. Such as the extra paths for the Rc car to move along, mostly however it is a poor imitator of modern warfare 2's experience with the added insult that the single player while flashy has no real substance to it.
There was a game a number of years ago on the original xbox called Black, it was better executed and amazing to play and was one of the first games to give feeling to the guns, modern warfare and battlefield bad company both also had this feel to their weapons which made the weapons fun. Sadly Black Ops did not.
Overall I would not recomend this game, the only possible thing it has going currently is that there will be many people playing it.
