ive had this game for some time now and it is the best ps3 game out mayb the best game out on any platform im totaly adicted to it its awesome i no there are many people saying that the campaign is to short but i dont believe that it is for example if you think COD4 has a short story you need to see army of two also the graphics of cal of duty are unbeliavale the sound is awesome its like your actually in the heat of battle but the main reason COD4 is on a different level of gaming to any other game is the online im addicted its so gd i mean there are many variations and game modes and its so simple you kill people or complete objectiive games to gain xp which will rank you up but a little tip 4 you if you ever meet the RIOT clan on there u hav no chance lol
