Summary: Not often do you see a primarily multiplayer shooter with an obvious amount of extra work implemented into it. The singleplayer is average at best, with set pieces that fail to entertain, an idiotic storyline, but it is generally fun. A co-op mode against the AI is welcome. It is short, but each mission offers some challenge and new gameplay experience; this allows the co-op to stay fresh without overstaying its welcome.
Summary: This game was extremely well made, especially for how old it is in comparison to several games. much less hacking than on CoD 4: Modern Warfare and much more fun than Modern warfare 3. This was my first Call of duty other than Call of Duty 3 on PS2 and it still is one of my favorite games. Something just feels right when you play this game and the classes are balanced well.
Summary: IMO this is the best of the COD games and one of the best shooters ever - great gameplay, beautiful graphics, and a great online server that still is active. I've spent hours online playing against others and it never gets old.
