There's only 4 professional reviews on metacritic so that's a good indication Activision thought the game would not be well received because if a game is thought by the publisher to be bad you don't send out review copies. But surprisingly all the professional reviews so far seem to like the game with 3 scores of 80 and one of 70.

So far no reviewers I trust have given their thoughts, but I'm optimistic and the complaint that the game is short at around 6 hours doesn't bother me. I might grab the game next time I get free store credit from Microsoft.
