Call of Duty is a first person shooter that takes place during the events of World War II. It was released on October 29, 2003 for the PC, published by Activision and developed by Infinity Ward. It is the first installment in the Call of Duty series, but was not as widely distributed until the release of the game Call of Duty: Classic for the Xbox 360 and the Playstation 3, remastered in high definition.
The game is based on the Quake III: Team Arena game engine. It was accompanied in September 2004 by an expansion pack, Call of Duty: United Offensive, which was produced by Activision, and developed by Gray Matter Interactive, with contributions from Pi Studios. Call of Duty is similar in theme and gameplay to Medal of Honor, as it is made out of single-player campaigns and missions. However, unlike Medal of Honor, the war is seen not just from the viewpoint of an American soldier but also from the viewpoint of British and Soviet soldiers, and is not as reliant on stealth as Medal of Honor. Also, unlike many other war games, Call of Duty introduced more computer-controlled allies who vary in quantity, providing the player with support throughout the games offering a more realistic WWII experience. Call of Duty also featured "shellshock" (not to be confused with the psychological condition of the same name): when there is an explosion near the player, he momentarily experiences simulated tinnitus, appropriate sound "muffling" effects, blurred vision, and the action moves slower.
