Great action, graphics and effets. Story is just enough to go on but the game is too short.
First of all the grapichs were really great as I expected in every way. I played in ultra mode and it was really stunning in many ways. Beofe the scene the f-18 were take off was incredible. The sounds and music was also very good.
Gameplay was so smoot and there was no bug for me and I completed game without having any problem. I played in hard mode and it was really realistic and really hard in some levels. You die after taking one bullet and sometimes I started to think I wish played in normal difficulty. AI was good enough but in some places I realized that they were pretty easy to kill because they were standing without a cover and no shooting.
The story, at the beginning I did not understand how this game started in NY, in a train but after all story was good enough to go on. The game was to short and I have a feeling that every FPS is going to be shorter than before. We will just get better graphics but less hours to play.
Level design, This is the worst part in game. I would expect more close combat like crysis but in many levels you have to shoot from a distance and you can get close to the enemy. in most cases you have to open fire from cover and it got you bored to do same thing.
I would recommend the game for any FPS fun and it definetly worth playing.
