As one of the most critically acclaimed shooters of all time, Call of Duty 4: Modern Warfare is a prime example of a tough act to follow. Yet, amidst a raging storm of anticipation and expectation, Call of Duty: Modern Warfare 2 has done it. The new campaign is chock-full of intense action and dramatic moments, and though it is more muddled than its predecessor (in more ways than one), it's still an absolute blast. The new Special Ops mode allows you to experience some campaign-inspired thrills with a friend and it's an engaging challenge to coordinate your maneuvers and tackle the varied objectives. Last but not least, the competitive multiplayer that took the online shooter community by storm two years ago is back and better than ever. Though the addictive action remains the same at its core, there are a host of new elements that make it more accessible, more strategic, and more rewarding. This all adds up to a thoroughly excellent package that is sure to thrill shooter fans and deprive them of sleep for months to come.
