As many have mentioned, the single player campaign, divided into 8 chapters, is quite short. I could imagine playing through the game over and over as a fill in between major game release cycles. Very good game cost, great graphics and great game play. The graphics in this game at 1920×1200 is sweet.
Anyway i loved the game and have nothing to complain about.

This is a top class shooter game with magnificent graphics and game play. Great variety of weapons and they all feel meaty and solid with good sound effects and destructive power. Lots of different types of levels ranging from open heavy warfare battle fields with tanks to close in room to room levels to sniper stealthy play outdoor levels. Its a challenging game where you may die many times before completing the level. The story is decent and keeps the game going with interest. A highlight is the drone robotic weapons which are a lot fun to control and they have different varieties of these, from assault drones to anti-vehicle drones to mini attack helicopter drones, all of them are well imagined and realistic and very useful in the game.

Some negative aspects – your fellow soldiers are hopeless and don’t help you much, they rarely kill any enemy soldiers and often get in the way of your shots.
