Dragged into the sun by two armed guards, you're being led towards a vehicle. By the time you've managed to have a brief look around at the beautiful surroundings and begun asking yourself where (or who) you actually are, you've received a rifle butt to the face and been thrown into the car. A short but harrowing drive through the city streets, filled with insurgents beating and executing prisoners, brings you to your final destination. In front of a television camera, broadcasting live around the world - a pistol is thrust into your face, and you are shot, point-blank dead.
As one of the opening scenes from Call of Duty 4, Infinity Ward lets us know from the get-go that this isn't going to be pretty. It's Modern Warfare. Ugly, harsh and gut-wrenchingly realistic.
