A great sequel to the series.
First off, the single player has you playing different roles including a mission where your teamed up with your villain. Which makes it a good variety of game play to go through. The single player itself is hard. Especially when you have 10 bots all shooting bullets and throwing grenades at you at once. Which nice, some fps's are a little to easy and the difficulty is just right.
There are some flaws to the campaign as well. It is to short. So for you offline players looking for the same experience as the first Modern Warfare. You aren't going to get it.
Single Player ~ 7.5/10
The graphics for this game are stellar as usual. Not a big change from the last of the series but there was no need for great improvement there.
Graphics ~ 8/10
The sound is phenomenal as usual not much to say there. Other than if you have surround sound it almost feels like your really on the battle field.
Sound ~ 10/10
Last but not least the multi-player:
The maps, the customization of the classes and guns, perks, and the arcade like point system make this game. It is single handedly the best online experience known to man up to date. No, other games online can be compared to this online. In fact most online games these days are copied ideas from the original.
Online ~ 10/10
Overall 8.5/10
