Pro: decent story line. Earn weapons and rank in multiplayer. Thats all i think of, the problems are the camera system the broken cover system. These two things alone are annoying, add in the difficulty online as well as off and you have a good plan gone bad. I was looking forward to playing online, i get on and am having to empty multiple magazines of ammunition. You have to shot people like on gears of war, they go down and you have to keep shooting them. The hit detection system both on and offline is very poor, leaving much to be desired for a SHOOTER game. I am very disappointed and expected much more than what i saw in the demo. Unfortunate to say but this game is one you should not even rent.
The main thing about this game that got me was the mechanics. I started to play this game on the hardest difficulty and i assumed it would be difficult but to be completely honest the guns in this game are horrible. I pick up an assault rifle on around the second level and I'm gunning down an enemy and it takes the whole clip and he still doesn't die. He has no armor on what so ever and then he starts running shoots me two times with a pistol and I'm dead. Smgs are probably the worst thing in this game the shoot fast but no accuracy at all two clips on a person standing still( I find that there is no need to mention the enemy AI in this game because there are already to many people talking about it).Although I couldn't play multiplayer I hope and believe it is better than the campaign itself.
