This mall makes every building and every drone in the game using a vertical bus.
It is inspired by Nilaus' mall, except the space requirements have been reduced tremendously by stacking the belts vertically.
To operate the mall needs all basic materials to be available on the logistic network. It proliferates all input materials before they're put on the bus, but it cannot proliferate buildings that have inputs that are not on the bus, such as upgraded buildings.
It may be best placed in the area just outside of the equatorial zone, so that it's nicely out of the way, but it also fits in the equatorial area.
For more information about this mall, see the steam guide.
