I recently have installed COD4 and I am completely amazed! The graphics are amazing. The flow from level to level is superb too make this game great for beginners to expert FPS. I have not played the multiplayer and I already know that this will be great! The only bad thing is that all this playing time will not get me any achievement points for xbox live.
I am sorry that the screenshots and the other graphics are such low qualit; you have to trust me that they look better in the game.
