Call of Duty: Ghosts (PS4) key

This game does not bring back Modern Warfare and it is also not a return of Ghost as your favorite character from the previous games. This is simply a new brand with its own series of sequels. 
Plot of the game takes place during ten years after the massive disaster that hit the U.S. so that it is no longer seen as a superpower. Plot of the game shows you a group of elite mercenaries known under the name Ghosts, who are fighting against the biggest threat yet.
