Im on the 5th level and it has taken me less than three hours. So far, its been pretty easy. It has started to get a little more challenging at this point. The achievements have been extremely easy so far and I have not tried online yet. I still may give it a nine depending on the remainder of the game and the online content. The controls are a little glitchy at times. No real shock value that the name/trailers made it out to be. But more to come.
