"A submerged machine, or submachine, is an independent structure of the subnet composed of different locations that have a common theme and similar architecture. All submachines discovered thus far are connected via portals. Each submachine plays a different role in the subnet, for example the basement is made for transporting energy and useful liquids, while the defense systems protect the subnet from the human infestation."@en .
