Infinity Ward does it again.
First of all, I like the new battle chatter system, where your squad mates call out the positions of enemy soldiers and machine guns. The healthless meter is also a neat addition, and to thoses ppl who say its not that realistic and the health bar is better, how is running aroung and picking up health pacls of the ground any more realistic? The AI of both your squad mates and the germans has also been greatly improved.
Now my only complaint is that at times where there is a lot of smoke on the screen, you'll notice that the frame rate will chug up a lot. Apart from that this game is great, and a must have 4 any person who plays first person shooters.
