Doesn't live up to the hype
Firstly, it is no different to any other war shooter, which makes me wonder why it was so well-received. It is no different to Call of Duty 3. The single-player mode is virtually the same, running through a bunch of long and boring levels, shooting anything you see.
The online play is ultimately ruined by campers who take all the kills. It does not take any skill and anyone who plays it could get loads of kills per match. The Last Stand and Juggernaut perks are also what makes it too easy, sometimes I find people running across the battlefield, getting dozens of kills and not dying. The worst part is they have no skill in the game at all.
I thought the Zombie mode would be an interesting feature, but instead I just get something that gets boring after about 5 minutes with continuous waves of zombies and nothing else.
Overall,this game is no different to the other Call of Duty titles and if you already own Call of duty 2 or 3, do not waste your money on this.
