Grandchester Mystery Mansion

Grandchester Mystery Mansion is a haunted house exhibition in Nuka-World in 2287.

Layout
This large building features several accesible floors. The tour of the building moves through the main floor, right until the kitchen. In the kitchen is a master locked door that leads to the basement. Inside the basement is a novice locked door with a bloody scene containing six trader corpses.

From the main hall and from the kitchen are three stairs going to the second floor. The doors on the second floor accessible from the main room are all locked and need a key (and are opened later as part of the tour). The door accessible through the kitchen is unlocked as it is part of the tour. The hallway upstairs is protected by an automatic turret.

The second floor has several chambers, the first one is rigged by gas and was used for seances. The gas can be turned of by using the terminal in the back left corner. The next hallway ends with dead end stairs, and the bedroom of the child on the left. Adjecent to the child's bedroom lies the parents' bedroom, currently in use by Zachariah.

Behind a master locked door in this room are the stairs to the attic. Entering the attic spawns a child that laughs and runs to the side. In this room are a weapons workbench and chemistry station. The child will run through a door on the back left shortly after spawning, and if the player were to open the door, a loud, jarring sound will be heard and one will find a dead end.

Notable loot

 * SCAV! Issue #4 (+5% explosives damage). On a wooden box in the attic storage/workshop.
 * Nuka-punch recipe book in the room with Zachariah.
 * A Protectron model in the basement, behind a master locked door. After entering the room, it stands on the right on a tool board.
 * A mini-nuke on the top floor, just behind the steamer trunk.
