With Call of Duty: Ghosts, there was no innovation, with a traditional campaign provided instead. Call of Duty: Ghosts' ending was also flawed, as Infinity Ward clearly wanted Ghosts to spark its own subseries. To do this, the developer provided fans with a cliffhanger that did not make much sense at all.
Although Ghosts delivers a great campaign, it doesnt make up for its campy and slow multiplayer and horrible infection mode.
