Call of Duty: Ghosts is a 2013 first-person shooter video game developed by Infinity Ward and published by Activision. It is the tenth major installment in the Call of Duty series and the sixth developed by Infinity Ward. It was released for PlayStation 3, Wii U, Windows, and Xbox 360, on November 5, 2013. The game was released with the launch of the PlayStation 4 and Xbox One. The game acts as a standalone installment in the wider Call of Duty franchise in lieu of the World War II, Black Ops and Modern Warfare series that preceded it. Ghosts inherits much of the core gameplay and structure of previous titles, with a mission-based campaign and an open-ended multiplayer, but introduces a near-future setting to the series as well as an increased focus on tactical gameplay, including the addition of new "Squads" modes and orbital strike superweapons to the multiplayer. Ghosts also features an alternative co-operative shooter mode titled Extinction, acting as a spiritual successor to the Zombies co-operative PvE gamemodes introduced to the franchise in Call of Duty: World at War. The science fiction elements of the game's campaign and setting would go on to be further explored in Advanced Warfare and Infinite Warfare. Ghosts received mixed reviews from critics, with most praising its multiplayer gameplay and for the introduction of Extinction, but criticizing it for its single-player campaign, rehashing of familiar concepts, and general lack of innovation.
