"In case you have quite literally been under a rock, or in a Turkish prison for the last 6 years (you’d be better off under the rock); allow me to fill you in about the series: Call of Duty was a 2003 first-person computer game created by Infinity Ward, with a narrative set in World War II, which just happened to spawn a couple of sequels. 2 was a launch title for the Xbox 360, and kept the WWII theme of it’s predecessor. Soon after, 3 was released on many consoles, as well as launch title on the Playstation 3, and also had the WWII theme. From this point, you may or may not have heard of the series, because it was not very intrusive; they were just a trilogy of FPS’, and not exactly pervasively popular. Then, in the Fall of 2007, Infinity Ward released their Magnum Opus, Call of Duty 4: Modern Warfare."
