A good and interesting co-op. The best parts from the first part were taken and doubled. More weapons, maps and customization elements. More modernization. The game is better optimized. But you can’t play it properly except with your own crowd of guys. It's obviously a co-op game. And with randoms, as usual, this is not very pleasant. You will definitely get a dose of fun if you play in co-op. How long it will last you and how long you won’t get tired of it is another question. But until this happens, you will get your experience and fan. There's not much to say about the music, not good but not bad either.
