Five cyberfactories were built on the planet. These were the state of the art construction machines, highly complicated hardware-software systems, capable of quick setup of various end-to-end automated factories and resource extraction facilities. Cyberfactories created all of the Polygon-4 infrastructure, and then went into preservation state. One of them, however, remained online and became the Assembly shop.
It is the first building the player is coming out from and where the game starts.
It leaves no message if the player visits it a second time.
