The war room in the Medal of Honor series serves as the main menu. The appearance of it has changed slightly from game to game. In the first game and Medal Of Honor: Frontline, it is modelled after secret underground bunkers used by British Intelligence during World War II. In Medal of Honor: Pacific Assault, it is based on a base camp used by the USMC, and it's appearance changes based on what mission the player is currently on. In Medal of Honor: Rising Sun, it is based on the interior bridge of an American aircraft carrier.
