Employee 004's first day. A disembodied voice named N.Gineer contacts her immediately and sends her to deal with a problem in one of the station's main reactors. She causes an explosion. The explosion endangers the world, her life, and the job she has held for approximately one shift. N.Gineer directs her to the Power Arm — a device capable of activating the electric panels that control everything in the station: doors, security measures, and the station's various environmental elements. Getting to the center of the station to fix what she caused is the only remaining option.
