Call of Duty 4: Modern Warfare2007
5 out of 5 stars
COD4 keeps you coming back for more. The ranking system, the weapon unlocks and the challenges you get XP points for are all great and add to the experience without taking your focus from the core gameplay. The single player game is great with some new twist in game modes and missions. The meat of COD4 is on-line. I think playing the story mode will prepare you for on-line. The replay value for COD4 is unlimited…
