Mixed on this title

I admit that this is the first Crysis on which I have mixed feelings.
I was right audience, even the two that I found very good.
But then I find difficult game to play: a wave of enemies that hits us and harassing us at the slightest detection, a painful switch permanently combination with a messy environment that makes it hard to distinguish his opponents .. .
Fortunately, the environment is of good quality, and overall good atmosphere it saves the title.
I hang not too much in the end I'll finish there because occasionally other titles await me.
