I personally play the game a lot .start to finish the game is the best .Best Fps game with great graphic .very good single player campaign mode for offline player and the multiplayer mode is very addictive.
I personally not play multiplayer mode for a long time.
In a single player mode if you select veteran the game is very very hard to play.
very good story line .
very good graphics .
very good game control.
if you not play the game go for it.
