BUT. I do not think that one should refer to this part as Schooter. I do not like this game Schooter and I find great. Refreshing provided to the last parts also once again with Secrets. I think it's great that the frustration rate is kept low, because you do not always have to find everything right away, but can return to the places at almost any time again. So you can at whim to take the time, even more difficult "tasks" to resolve and move them if you still can not find anything.
The game is varied and diverse and like a movie going all cinematics fluent in the action on. As for the bad reviews, I have a theory. Yes, there occur some partially strenuous gunfight scenes that are a bit more than I would like, but they are usually, if not always right away, detachable and mostly they also amuse me. Frequently, however, one must actually more tactics, as a charge on 10-20 degrees consistently. So you can single attack from behind or eliminate (later) unnoticed with silencer from the others. Sometimes a temporary escape is sometimes better to want to stand up as all.
I can only recommend this game, just those who mainly preferred the older parts. Because there are actually a lot to discover and sometimes you have to think properly, how do you reach point X, in which apparently what is again to find. :)
