Call of Duty 4: Modern Warfare review at 4ColorRebellion.

"I have been playing first-person shooters since Doom debuted on the PC, and few since then have stood out as much as Call of Duty 2. I first played the game in 2005, in a Circuit City while on vacation in New Orleans. While everyone else was shopping for presents, I went to the videogame section to check out all the new demos. I saw someone playing Call of Duty 2 on the Xbox 360 and was intrigued. After the person quit, I started playing and instantly got hooked."
