Campaign had a cool story going on but a lot of the missions were completely shit. There are a handful of memorable parts of this campaign but the most I remember is the gameplay being ass. Multiplayer also was terrible, some of the worst maps they ever made for CoD yet. It had cool modes and ideas but the gameplay yet again sucked. The only thing I liked about this game was extinction. Fighting aliens instead of zombies was cool as hell and the dlc maps for it were awesome. It was a great mode and a lot of fun for what it was. The only reason this one has 2 stars is because of the extinction mode. A truly crappy game.
