Best to Worst Zombies Maps

This is a top ten list, but I'm putting these in order of my favorites, best to worst. I will be changing this list as time goes on, but I will be including Infinite Warfare and Advanced Warfare in this list. Suck it, haters.
This list is a non-votable list and the content of the list reflects the opinion of its author.

The Top Ten

1 Origins

Don't need explanations for this choice.

2 Mob of the Dead

So dark and creepy, this map fits in perfectly to help make Black Ops 2 Zombies far better than it was before. With two bad maps, we needed one good one to bring that game out of the water.

3 Gorod Krovi

This map brought us the PPSH-41 and FFAR and even a good Flamethrower? I'm hooked.

4 Der Eisendrache

This map is a bit overrated, but not too badly. It's good, but not nearly as good as some other maps on this list.

5 Moon

This map is underrated, with the Wave Gun, the QEDs, and the awesome level design. It's a gem.

6 Ascension

This is better than Kino for two reasons, one is difficulty and two is the Gersch Device.

7 Kino Der Toten

This is a fun map to play occasionally, but nowhere near as good as the others on this list.

8 Zetsubou no Shima

Why did I put this above Der Riese? Der Riese is severely overrated, and there are better maps. This one is challenging and fun, but it does lack in things to do, as well as challenge in easter egg and wonder weapon creation.

9 Der Riese

It's a classic, but I'm not putting it nowhere near number one.

10 Shangri-La

What the hell is wrong with people? This map is awesome! Sure, not like Der Riese, but it's got enough challenge and grit to land it at number 10.
