IGN has give the review for CoD4 and it has a very good rating
Presentation
If this is war, consider me a future draft-dodger
9\10
Graphics
From top to bottom, one of the best-looking console games around
10\10
Sound
The explosions will shake you; the constant sounds of gunfire will put you on edge. The end song is an added bonus and properly immortalizes the unfortunate phrase, "Go deep and hard."
9.5\10
Gameplay
An excellent shooter that is as intense an experience as you can find in gaming. The multiplayer is also top-notch
9.5\10
Lasting Appeal
The single-player experience is brief, but there are many other things that will hold your attention once the campaign is complete
