Fallout 3 locations project
The front door opens to the vestibule. Walking inward, the living room has access to the kitchen, restroom, and the stairway to the second floor. In the kitchen, there are a few caps on the table, and a fridge concealing a toolbox behind it. The stairway will take you to the second floor.
This floor consists of only a bedroom. Brandice's terminal (easy) is on the desk. Next to the terminal is an active radio playing Enclave radio suggesting that Brandice's father was either spying on the Enclave or used to be a soldier for them (possible suggested information from Bryan Wilks). An other terminal log mentions the gun hidden in a behind downstairs. The bed is not owned, and can be slept in.
Brandice's house appears only in Fallout 3.
