Best in the series
Call of Duty 4 is without doubt the best Call of Duty game ever made. From its' jump from WW2 to Modern Warfare to its dynamic and powerful single player this is one shooter that is essential to get. The single player campaign is short, however depending on what difficulty you choose to play the game on. If you play it on normal then expect to play for 4-5 hours before completing it. However this is doubled if you play in Veteran as you have to camp more, move slower and yes retry alot. However if you don't have online, don't buy this game because this game is all about its online play. It delivers a deep online play that people will be sucked into however everyone who plays the game is now an expert so if you're a newcomer you might get fustrated. Sadly the same occurs if you stop to play because 70% of people playing have no life. Overall a terrific game.
