Haven't touched a COD campaign since MW3, nor do I plan to. Multiplayer is such a dissapointing step back from MW. Whenever friends ask to play Cold War I suggest MW instead. Zombies, however, is awesome. I could play it all night. Enough fun stuff to do that it doesn't get boring even on round 35, and the evac feature is nice. I like the crystal upgrades as well. And getting to pick the gun you start with is such a great QOL feature that has allowed me to focus on upgrading my weapons rather than dump money into the mystery box. Very happy with this edition of zombies, the other modes can buzz off for all I care
