Call of Duty 4 although short in story mode is enough to satisfy you. Set in modern times you deal with Russian rebels trying to take over russias corrupt government and a terrorist leader who took over presidential powers in a made up middle eastern country. The russians are trying to supply the terroist group with nukes and you have to stop it. When playing the game you first start off playing as the British S.A.S and then later you play as a soldier in the Marine Corps Devil Dog unit. This game does not let you rest it is intense and brutal Rpg's flying by your head, bullets wizzing by from AK-47s. I highly recommend anyone who ownes an Xbox 360 to buy this game. This game is 10 times better than Halo 3.
