Zombie Army 4 - Brutal/Nightmare | All Roads Lead to Hell 2/4 | No Deaths/Revives

Got lucky running through the underground area XD
My First Brutal/Nightmare playthrough! I had just recently gotten the season passes, and thought of now completing each level now that I have them all! I am not familiar with Nightmare Spawns, so I may be a bit slow in some areas.
No deaths or Self-Revives per chapter allowed for more fun!
