The abandoned house. Keeps that one to himself, he does. That's where it is. That's why he doesn't want us in there.”— Old Lady Dithers on the whereabouts of the failsafe.
The abandoned house is a house in the Tranquility Lane simulation in Fallout 3. It contains a hidden terminal which allows the player to complete the Tranquility Lane quest without satisfying Betty's morbid sense of entertainment.
As with all houses in Tranquility Lane, it has 2 stories, with the front door entering into the living room, which features a garden gnome, cinder block, glass pitcher, broken radio and an empty soda bottle. The other ground level rooms are a bathroom and a kitchen. Upstairs, the house has another bathroom, and a bedroom with 2 single beds.
In a stark contrast to the pristine condition of all the other houses in Tranquility Lane, the abandoned house is noticeably dark and unkempt, with much of the furniture knocked over.
Outside, a doghouse can be found on the front lawn, in the right corner.
- During the process of completing the quest according to Betty's tasks, the doghouse outside can be interacted with to retrieve the Pint-Sized Slasher gear.
- The beds on the second floor can be slept in.
The abandoned house appears only in Fallout 3.
