Great sequel to an already great game
My first reason why this is is because the story has gotten alot more intense and thought provoking this time around. One thing about the story is that alot of the game accually has fighting happening in America, which is the first time in a game that I have seen this. With the events happening in America, the fighting feels more personal "if you are an American Citizen". The ending of the game, which I am not going to spoil ends with a very dramatic event like on CoD4. The main problem with the story is that it is a bit short. But even with that the story is still one of the high points for the game.
Another aspect about the game that has been improved is the gameplay. The gameplay has more options to choose from to finish a situation. The areas in which you fight are a little larger this time around and have more space to move around. Another aspect in the gameplay that have benn improved is the AI. This time the AI is smarter and wil flank you more than on CoD4. The controls also feel a bit more fluid this time around, but it could just be me. The gameplay is improved and will make most people happier.
The graphics are improved a bit with more detail on the guns, but I am not going to get into much detail about it. They are not the best graphics of the year though.
The last thing that I am going to review is the multiplayer. The multiplayer was the greatest part in CoD4, but is improved slightly in the fact that when you get kills streaks you have more weapons at you disposal to use against the enemies. The maps are also improved in that there are more places to surprise your enemies.
The game is a great improvement to an already fanastic formula. I am putting this game down for a nominee for game of the year, which in my opinion shout win.
