I loved the first one, but the sequel is just annoying. You can't skip cutscenes, even after you have seen them already. This gets to be ridiculous after you die at a checkpoint a couple times. Loading times are pretty bad as well. I made it through about half and then I had to switch to MW2. Save you time for Bioshock or Mass Effect 2.
The game has great graphics. The story is very weak. There was only 1 challenging part on the whole game and it wasn't the end. Im sooo glad I didn't buy it!! I hate the controls with having to move the screen to the left or right during coop; I prefer being in the middle of the screen. The weapon customization is good and offers a lot of different color styles for them. I liked the first game a lot better than this one. I had very good hopes for this game after playing the first and this was just sad.
