I really loved this game! It made improvments on everything and was great to play. controls were smooth and responsive. I played levels over and over just to get the right action. Plenty of replay value with the other ways to kill.
My only problem was that when you impersonate somone and you come across some of the same you can be spotted. My thing was If its a small group of bouncers or janitors I can imagine you would be spotted, but the whole Chicago Police knowing if there is somone who dosn't belong? or how about wearing a uniform that covers your face such as the bio hazard suits. No one should be able to see I don't look like somone.
