A little short, but awesome...
The story begins when you are airdropped to a remote island which has been taken over by the Koreans, and you need to rescue some civilians. Obviously, things aren't as they seem. So, as the story unfolds mission-by-mission, you get treated to a rich, lush outdoors and a freezing, crystalline indoors.
The attention to detail in this game is staggering. You can pick up almost any object in the game, and your nanosuit takes the game to an entirely different level, giving you more options for taking out the enemy.
I personally felt that the ending was a little choked; I felt that this was going to be an end-of-the-world kind of premise, but after the game I sort of felt that the game almost went there, but came back. The game feels a little too "localized"; like all the bad stuff is happening only around you and nowhere else. The game could have been even better if that element had been incorporated.
This is perhaps one of the flawless games for which no patch was released. I did get stuck on a particular mission... On the ship, after meeting with the admiral when you need to go to the armory, the admiral just disappeared and the armory door never opened. I had to reload that level to resolve this issue...
Anyway, excellent game, though I still think it can't top Call of Duty 4... hope you guys enjoy both games!
