Constantly crashes/ disconnects from server. Every update brings more issues than it corrects. Gun fight maps are almost entirely the same from mw2. Zombies crashes if you fall from a tall building. Recharge time on schematics is way too long. I constantly have to restart the game for it to even load properly. Ttk varies widely between weapons. Ranked play only works a quarter of the time. I could go on and on all day about the problems with this game.
