Gröesten Haus: Secret Room

The ten lanterns

The Mystery Box of Gröesten Haus waits behind two locked doors on the first floor. To open them, shoot the ten lanterns hidden in and around the house, in any order. Each one hit plays a raven’s caw and lights a small purple flame inside the glass.

A lantern

Old oil lanterns, hung from the beams or set on the furniture. Four are on the ground floor, four upstairs, and two outside, only visible through the windows.

According to the guides, the lanterns are:

On the wooden column in the middle of the main room of the ground floor.
On the wooden column near the stairs, in the same room.
Outside, on the hood of a German truck, seen through the window at the foot of the stairs in the main room.
Hanging from the ceiling of the kitchen.
Above the dining table of the kitchen.
Outside, seen through the window to the left of the kitchen counters.
Upstairs, to the left of the corner where the Prologue has its Geistschild and Gröesten Haus its Combat Shotgun.
Upstairs, on the table across from that corner.
Hanging on the corner to the right of the locked doors of the secret room.
Hanging in the upstairs room above the living room.

The two outdoor lanterns are the hardest to spot in the dark; the muzzle flash of a weapon helps to see them.

The Mystery Box

When the tenth lantern is lit, the two doors upstairs open, and the room behind them stays open for the rest of the game. The same secret exists in the Prologue.

The room

A small room on the first floor, next to the Random Blitz and in front of the piano.

Mystery Box

1,000 Jolts a draw. It gives one random weapon or a Jack-in-the-Box, and it can be used as often as the Jolts allow.

On ZFRR

The Gröesten Haus leaderboard does not allow the Mystery Box room to be opened, in either category. A record is played with the three weapon lockers and the starting weapon.
