here is the map layout for the zombies map IX for Call Of Duty Black ops 4. I did not create this map and it is referenced from a REDDIT post by Downiehoofd who also made the map from scratch. Its a very easy to read and follow map with some good graphics that should make finding anything on this map a doddle with a quick glance of it.
IX is set at a gladiatorial arena sometime during the 80s BC. The map is relatively small, with players spawning in a tunnel that leads into the main arena. From there, the player can either buy the door to the Danu temple or Ra temple, with the Odin and Zeus temple gates being accessible from the inside. Each of the temples connect to a circular underground chamber, which leads into the main temple that contains the Pack-a-Punch Altar.
Thanks for reading guys and gals.
