On the left is the ending of 2009's Call of Duty: Modern Warfare 2. On the right is a scene in Call of Duty: Ghosts, released yesterday.
Ghosts, which has already made a billion dollars at retail, has the lowest Metacritic score of any mainline entry in the series.
Critics have taken the game to task for being a stale retread of the annual series.
Correction: An earlier version of this article stated that the scene from Ghosts was its ending. It is from earlier in the game.
