The Xbox 360 edition also takes gamers behind-the-scenes with a bonus DVD containing more than four hours of interviews and features, an exclusive documentary exploring the British S.A.S from World War II to modern day, and a series of “making of” vignettes highlighting Infinity Ward’s research, technology and story development for Call of Duty 4: Modern Warfare. For Windows PC fans, in addition to the hardcover art book, the Limited Collector’s Edition for PC will include a digital copy of the BradyGAMES Official Strategy Guide. The strategy guide provides players with a detailed single-player walkthrough, top-down maps, multiplayer strategies, weapon load-outs, and numerous other tips for the hardcore soldier.
