The station is divided into two sections, the Main Deck and the Breeding Areas. The Main Deck houses most of the station's important facilities, including the Docking Bays, the Quarantine Bay, the Operations Deck, the Habitation Deck and the Reactor Silo. A Sub-Zero Containment Room in the Main Deck area was used to store the corpse of Ridley. The Breeding Areas encompass the lower portion of the station. They are made up of breeding areas and terrariums of different environments, which are divided into six sectors based on their environments (Not counting the Restricted Zone).
