Fantastic . Best game i ever played , and I'm still playing :-)
Singleplayer and Multiplayer , nothing can even compare with it , i've played COD4 for about 650 hours and i just love it .
Singleplayer campaign it's awesome .Too bad it's so damn short . But better than long and boring . Great story , gameplay , sounds and graphics . Voice acting it's amazing , the feeling it's just "wow" . It's the only game i've finished for 3 times , and it's not over yet :-)
Multiplayer . hmmm . BEST EVER . Certainly . The gameplay it's fantastic . I love to complete the challenges , unlocking perks and stuff . Custom classes are again a big + for this game . Weapon customization ...
I have no words for this game . Certainly a must play . I don't even imagine a gamer who didn't played this game
After this , i was expecting a lot from MW2 . But i was dissapointed . I've played MW2 for ~1 week and after that i got bored and go back to COD4 .
