This game is astonishing. I loved it because the campaign is unusual longer than the ones in nowadays shooters. It's tactical (not so tactical like the previous ones) and you can ask your teammates shoot on a particular target, you can order them to heal each other. You have different weapons for different situations. You have to use stealth in certain situations.
The story is not so interesting as it seemed to unfold at the beginning, but it's something compared to other shooters.
Overall a great game.
