Engineering is where the core powers the station, and it's also where one needs to go to have their cybernetics repaired. It's very dark in engineering often. Analog equipment beeps and boops day in and day out, and the two engineers down there spend almost all of their time drinking Fountain View and playing videogames. It can honestly be a really creepy place when it's empty -- not unlike the terraforming plant on Aloha. Without the core, Agoli 5 would cease to function.
