What are your most Underrated Zombie Maps?

For me it's got to be Shaolin Shuffle from Infinite Warfare. Though I don't like the Easter Egg or Pack a Punch process, its pretty easy to learn after a few playthroughs. The setting and style of the map are absolutely amazing, and it makes me feel like I'm in the living and breathing streets of 70's New York City. The Chi abilities are a ton of fun to use as well, and multiple different abilities make the map very repayable. Though I understand why most of the community dislikes the map (cough, ninja zombies, cough), I can't help but love the experience as a whole. The ninjas can be killed pretty easily if you focus them as soon as they spawn, and honestly the map wouldn't be the same without them if you ask me. I honestly can't tell if I like this map or Spaceland more to be honest!

Now I'm curious to hear from you. What are your most underrated maps across all of Call of Duty Zombies?
