The followup to IW's hit game "Modern Warfare". It has an intense 1 player campaign, a unique co-op system called Special Ops, and a multiplayer component that some call the best ever and "an unbalanced, overrated piece of garbage". Personally, i think the multiplayer is intense and exciting no matter how long you've been playing.
Kid 1:Modern Warfare 2 is the best invention since toilet paper!
Kid 2: Modern Warfare sucks halo is 100 times better.
