Nearly nothing is known about the apartment except during some time in history, the apartment caught fire. However the apartments have no influence on the story whatsoever, neither is it accessible to the player at any point.
The apartment is a simple white brick building, that has many windows, a few awnings, and a giant burn mark on the front. There are four power generators on the roof, along with a fan system, and two chimneys that have smoke coming out of them at times. Around the back, the windows glow blue, pointing towards the Epsilon Program possibly having something to do with the fire.
