Cawldwink When it comes to Zombies, the fog was never meant to be added in the first place. Jason Blundell did an interview where he discussed pre BO2 Zombies and what Jimmy planned starting with Tranzit. They used the fog to hide texture pop-ins and the denizens to slow down players traveling through the fog. The same went for using gumps to load/unload assets for different sections of the map, as the current Tranzit was taxing on the console. A lot of features was cut due to hardware limitations at the time, which is the main reason Tranzit and many other maps don't look finished or appear bland. Limitations were their biggest issue, leading to sacrifices to try to achieve steady FPS on console. Where the PC version of BO2, however, benefited from better hardware. PC version is basically a port from console with its own optimizations and customizations for better graphics, etc.
