Released in 2013, Ghosts introduced a new world where the United States is no longer a superpower. It features:

Call of Duty: Ghosts is no longer sold in a functional state. The Steam version still requires an account, still phones home, and still includes Denuvo (though cracked long ago). But more importantly, the DLC is delisted in some regions, and the Extinction episodes are no longer playable with randoms. The repack represents a frozen, complete, offline-forever edition.

A unique 4-player cooperative mode where players battle an alien threat instead of the traditional zombies.
