Modular hall units load with just a click to make any length corridor you need. The main hall is a figure with opening doors off to one side that operate with the turn of a dial. Two smart prop units will load to the front or rear of the figure with preset .PP2 files. The 90 degree radius hall unit has a observation window which comes a storm shutter in case the view changes for the worse. Simple camera positions are included to help you get started.
