On the highest difficulty without killing anyone, really challenging. Great atmosphere. Such games nowadays there are unfortunately only rarely and they are becoming less and always easier and soon the games anyway by itself. But when you have to tackle Dishonored even himself. The degree of difficulty is never unfair, 100% buy recommendation, if one stands on sneaking. You can make the game even by gamble with murder and manslaughter, but what I can not say anything because I did not want to make such experiences.
