BO3 zombies high round guide

Guides for the zombies maps in COD: Black Ops 3 Zombies
I haven't played Gorod Korovi, Zestubou no Shima, or Revelations much, so the installations will come later.
Includes guides for:
Shadows of Evil
Der Eisendrache
The Giant
Let me know what you think and of you have any other ideas, as I would LOVE to hear from you!
