If you have played Call of Duty 4: Modern Warfare then Modern Warfare 2 will probably feel like more of the same. But developer Infinity Ward has struck upon a formula for action that works and change for the sake of change would only bring disaster. The new additions are mostly minor, but they’re all improvements. The campaign doesn’t shy away from exploring some dark themes, and the result is a story that weighs on you even if there are some plot holes. The multiplayer simply gives you more of what you want: more unlockables, more perks, more killstreaks, more challenges, more ranks, and as a result, you’ll be upgrading something nearly every round. Finally, the new cooperative Spec Ops contains some of the most satisfying and frightening firefights of the entire game. The game is an evolution of a proven formula; it’s more of the same, made better.
