Will Tuttle of TeamXbox concludes his review by saying:
"Simply put, Call of Duty 4: Modern Warfare is an instant classic. The fact that Infinity Ward has created a modern-day masterpiece probably isn't surprising given their impressive track record to date, but our lofty expectations were actually surpassed in many ways. The single-player game was particularly surprising, as none of us expected the game to have such a compelling, narrative-driven campaign. It's one of the best stories of the year, and it instantly thrusts Infinity Ward into the storytelling pantheon with developers like Valve and Irrational. Of course, one can't forget the multiplayer, which is just as addictive as we hoped it would be. Infinity Ward has officially killed off the WWII FPS genre, and we can't wait to see what they have in store for us next."
