When this was first released, I stuck by COD4, and refused to buy this. Now it's in the sale, I decided to invest in it.
It is absolutely amazing. The career is very good with a variety of missions. The ability to create your character and modify with various different clothing, armor, weapons and camo colours adds an exciting edge to the game.
Multiplayer is good, but not brilliant. It becomes a little unrealistic with people running about in bright pink camo - but still, it's only a game.
The terrorist hunt is a good game mode. Being able to change a variety of settings deciding how many are on each side etc. can mean a different style of play each time.
I would recomend this game to anyone who enjoys FPS!
