Ehhh, it's ok.
I give the game props for being what it is. I love the setting and the fact that it can be a sneaky game or a blazing guns game. The actual story, from what I read out of the manual, sounds very interesting. The only reason I have any resentment towards this game is because I cannot customize the controller layout the way I want. The rest of the game is good.
If you are the type of person who can play a shooter with a different, more old school, controller setup then you will like the game. If you cannot adjust to the controller scheme, then don't buy this game.
