Q211096

Call of Duty is a 2003 first-person shooter game developed by Infinity Ward and published by Activision. It is the first installment in the Call of Duty franchise, released on October 29, 2003, for Microsoft Windows. The game simulates infantry and combined arms warfare of World War II using a modified version of the id Tech 3 engine. Much of its theme and gameplay is similar to the Medal of Honor series; however, Call of Duty showcases multiple viewpoints staged in the American, British, and Soviet campaigns of World War II in Europe.

The game introduced a new take on AI-controlled allies who support the player during missions and react to situational changes during gameplay. This led to a greater emphasis on squad-based play as opposed to the "lone wolf" approach often portrayed in earlier first-person shooter games. Much of Infinity Ward's development team consisted of members who helped develop Medal of Honor: Allied Assault. On release, the game received universal acclaim and won several Game of the Year awards. Retrospective assessments have been less favorable, with many critics saying the game aged poorly; it has placed low in lists ranking the series' games.
