The office section of Capitol Post contains a small reception area, and a back room with terminals containing stories published in the pre-war Capitol post, and a printing room in the basement. One of the terminals is rigged (first terminal on the right) and the reception terminal is linked to a sometimes hard to discern safe, situated in the left panel of the receptionist desk (when facing the terminal).
There is a locked door that leads to the terminals, but the player can simply walk around it where there is a giant hole in the wall, leaving hardly any "wall" at all. The only enemies found in the office are several radroaches.
In the printing room, below the main lobby where the floor has collapsed, the body of Gibson can be found, along with a brief note and the key to his house in Minefield.
