What an absolute throwback! This Custom Zombies map truly is incredible & the best part is not only did i get to revist an OG classic WaW map but i get to play Black Ops 1!! which for me is the best Call Of Duty ever created.
 
Here is my playthrough for those who want to see this map...

Incredible map! Visually looked very nice & it ran pretty smooth as well. I completed the easter egg & escaped successfully.
