Everything in this game is fantastic. It has great graphics, storyline(s), controls and gameplay.
Even the introduction to the game (cargo ship) is breath taking.
The idea of the game is very much like any other FPS out there (you have a gun, go and shoot bad people) but the execution of the storyline and the excellent graphics means it feels so much more than just a game. You play as one of two characters, Soap who is attached to a small SAS team or Sgt Jackson who is a part of the USMC (a marine) I personally felt more attached to Soap rather than the marine as the game didnt really give the marine much character. I think this was probably down to americans being gung ho rather than a close knit team like the SAS. These two characters have seperate missions like 'rescue a hostage' etc. The missions of each character are related to one another, however, which makes the whole game a rather good story seen from differing perspectives. I wont go into anymore detail here as it would spoil it.
If you havent got ths yet then what are you waiting for!!
You wont be disappointed.
