In a big place like RuptureFarms, it isn�t enough for elevators to just go up and down � they have to go back and forth, too, and that�s where Ball Cars come in. Operated by a complex series of relays and conveyor belts, Ball Cars connect the distant divisions of massive Facilities with a system that�s half-elevator, and half inter-office bullet train. As an added benefit, Ball Cars have security interlock features that ensure no unauthorized personnel can use them to reach sensitive areas (unless they happen to be a clever Mudokon terrorist named �Abe�.)
