Campaign - Nothing to complain, yet.

Multiplayer - Cheaters already, gamepad users are basically always using Cronus; Activision still tolerates it, not surprised at all.
You can't edit blueprints at all.
Sometimes changing the weapon attachments will boot you into front-end then loads you back into the lobby, so you can't even edit your weapons anymore.
Every other match is also a black screen, so I have to reboot the game every damn time.

Zombies - Cold War with new maps, from what I could gather out of my 10 hours in it...
