I present to you:
Firing Range
and it even has it own zombies name: Quarantaine
In BO1, Firing Range had all of these references to zombies ( Dempsey's name in bullet casigns, the pack a punch flag, the teddy bear, a letter outside of the map containing a very cryptic and weird message, and some quotes from our characters engraved on the walls of the map)
It had a lot of zombies references
Wouldnt be cool if treyarch decided to give this map a chance to become a zombies map instead of nuketown?
Also, they could have done since they added Firing Range to BO6 so they could have the assets already
It would be a nice throwback and reference to the old BO1 zombies references the map had and it would also be a compleyely new experience to zombies in general since we haven't seen that map on zombies
