There is nothing fresh or new about this game. It feels like just a very small expansion on the prior game.
Weapons are buggy (i.e the game grash every time I try to put an attachment on a LMG), the maps are largely just carbon copies of prior maps, and the best mode (DMZ) has been replaced by a zombie hack-a--thon.
It's clear that this release was pushed up by months.
Sad day for COD fans.
