don't expect much of a cod-campaign other than some nice set pieces and cool scripted action sequences. And on that it delivers, like always. The game engine also received some meaningful updates since I've last play cod. Where the game really shined was in the last 2 missions you do, especially the one "inception"-moment is absolutely amazing and I sure as hell did NOT expect it in a cod game.
The multiplayer is business as usual and since I like to play br-games more, it really functions more as a warm-up (and also leveling opportunity of all the guns i'd use in warzone).
Call of Duty is nothing out of the ordinary and plays a lot of it safe, but it was and probably will be a constant player in the shooter genre. And I'm fine with that.
