When i played call of duty 4 modern warfare i was totally amazed.Call of duty 3 didn't come out for pc so i was waiting for this one very much.My opinion is that call of duty 4 has one of the best game plays i have ever seen.Apart from that it is not difficult to play cause of the good movement of the weapon the player is using.The single player of this game is magnificent i have to say.I personally finished the game 5 times,without getting bored.It's one of the most addictive FPS ever seen.Even when call of duty world at war came out,people continued playing call of duty 4 and refused to play the new one.When i say addictive i am mainly talking about the amazing call of duty 4 multiplayer.....Play all day and you will never get bored!!!!I'm serious...There are also the greatest modes in this game.Zombie,sniper,promod....I mean you CAN'T get bored!!! Buy this game and you will never regret it.That's all.!!!
