This is the complete mansion map for Uncle Otto's Mansion, detailing the full layout across all four floors, including every hidden room and critical item location. Forget wandering aimlessly; this guide breaks down the entire estate, from the flooded Cellar to the dust-choked Attic. The mansion is a puzzle box, designed to mislead and disorient, but its logic can be cracked.
Your primary goal is to collect three Ceremonial Masks—the Owl, the Serpent, and the Wolf—to unlock the final door in the Observatory and confront the entity controlling the house. This requires solving a series of interconnected puzzles and finding keys scattered throughout the estate. The mansion's layout is non-linear, but certain areas are gated by specific items.
The Complete Mansion Layout: A Floor-by-Floor Breakdown
The mansion consists of four primary zones: the Basement, the First Floor, the Second Floor, and the Attic. While you begin on the First Floor, you will need to backtrack frequently as you acquire new keys and tools that open up previously inaccessible areas.
First Floor: The Heart of the Estate
The First Floor serves as the central hub. It’s where you’ll find the main entrance hall and access to the estate’s primary wings. Many doors will be locked on your first visit.
- Grand Hall: Your entry point. Contains the large Grandfather Clock (a puzzle) and the main staircase to the Second Floor. The door to the West Wing is locked with the Serpent Key. The door to the East Wing is initially open.
- Dining Hall: East of the Grand Hall. A key story note from the housekeeper is on the table. A dumbwaiter here can be used later to transport an item from the Kitchen.
- Kitchen: Connected to the Dining Hall. You'll find the Dull Kitchen Knife here, useful for cutting a specific rope in the cellar. The Basement Key is hanging on a hook by the pantry door.
- Portrait Gallery: A long hallway in the East Wing filled with portraits of the Otto family. Interacting with them in the wrong order triggers a trap. The correct sequence is revealed by a clue in the Library.
- Conservatory: A glass room with dead, thorny plants. The Gardening Shears are found here, necessary to clear the thorny vines blocking the door to the Study.
- Study: Accessible after clearing the vines from the Conservatory. Uncle Otto’s diary is on the desk, providing crucial backstory. Behind a false bookshelf is a hidden safe requiring a three-digit combination.
Second Floor: The Family's Private Quarters
The upstairs area is more personal and holds the secrets to the family's strange rituals. It’s quieter, but the threats are more concentrated.
- Master Bedroom: Uncle Otto’s room. Locked with the Silver Key found in the Library. Inside, you'll find the Observatory Key and a chest containing one of the three Ceremonial Masks: The Wolf Mask.
- Guest Bedroom: A seemingly empty room, but pulling a specific candelabra on the wall reveals a secret passage to the Balcony.
- Balcony: Overlooks the Grand Hall. The Attic Crank is lying on the ground here, essential for accessing the top floor.
- Library: A massive two-story room. A puzzle involving placing books in the correct order on a shelf reveals a hidden compartment containing the Silver Key. A note on a reading table gives the solution to the Portrait Gallery puzzle downstairs.
- Observatory: The highest room in the main house, accessible via a spiral staircase in the Library's upper level. The final door here has three indentations, requiring the Ceremonial Masks.
Basement: The Mansion's Dark Foundation
Accessed via the Kitchen, the basement is damp, dark, and dangerous. It’s a small but critical area for progressing the main story.
- Wine Cellar: A maze-like series of shelves. Be wary of the Stalker enemy that patrols this area. The Crowbar can be found here, used to pry open boarded-up doorways.
- Furnace Room: Contains the mansion's main furnace. A note is pinned to the wall with the safe combination for the Study: 4-8-1.
- Flooded Storage: This area is initially inaccessible due to high water. You must find the drainage pump controls in the Furnace Room. After draining the water, you can retrieve the Serpent Key from a chest, which unlocks the West Wing on the First Floor.
Attic: Dust and Forgotten Memories
The final main area, accessible only after using the Attic Crank on the mechanism found in the Second Floor hallway. The crank lowers a rickety staircase.
- Storage Room: Filled with old furniture covered in white sheets. One of the sheets hides a mannequin wearing the Ceremonial Mask: The Owl Mask.
- Servant's Quarters: A small, spartan room. A music box on the nightstand plays a tune that is the solution to the Grandfather Clock puzzle in the Grand Hall.

Solving the Mansion's Major Puzzles
The mansion is home to three major gatekeeping puzzles. Solving them is mandatory to collect all the items needed to finish the game.
The Grandfather Clock Riddle
In the Grand Hall stands a large clock that has stopped. A small inscription reads, "Set me to the time of her final lullaby." You cannot solve this until you reach the Attic.
- Find the Clue: Go to the Servant's Quarters in the Attic.
- Activate the Music Box: Wind the music box on the nightstand. It will play a short, haunting melody.
- Note the Time: A small plaque inside the music box lid is engraved with the time 2:55.
- Set the Clock: Return to the Grandfather Clock and interact with the hands, setting the time to 2:55. The clock face will open, revealing the Ceremonial Mask: The Serpent Mask.
The Portrait Gallery Sequence
The East Wing's Portrait Gallery features five portraits of Otto family ancestors. Touching them in the wrong order causes the floor to give way, dropping you into a holding cell in the basement.
- Find the Clue: A note in the Library titled "Family Lineage" describes the order of succession. It reads: "The Baron, then his twin daughters, the General who followed, and finally, the Scholar who documented it all."
- Identify the Portraits: Examine the plaques beneath each portrait: Baron Viktor, The Twins (Eleonora & Evelyn), General Matthias, and The Scholar (Albrecht).
- The Correct Sequence: Interact with the portraits in the following order:
- Baron Viktor (the old man with the stern face)
- The Twins (the portrait of two identical young women)
- General Matthias (the man in military uniform)
- The Scholar (the man with glasses and a book)
- Claim the Reward: A hidden panel will open beneath The Scholar's portrait, containing the safe combination (4-8-1) for the Study safe. Inside the safe is the Librarian's Monocle, an item that reveals hidden text on certain documents.
Frequently Asked Questions About the Mansion Map
How do I get into the Attic? You need the Attic Crank, located on the Balcony of the Second Floor. The Balcony is accessed through a secret passage in the Guest Bedroom, activated by pulling a specific wall-mounted candelabra. Use the crank on the mechanism in the Second Floor hallway to lower the stairs.
Where is the safe and its combination? The safe is in the Study on the First Floor, hidden behind a false bookshelf. The combination is found in two parts. The clue to the combination's location is in the Portrait Gallery puzzle reward, and the actual numbers, 4-8-1, are written on a note in the Furnace Room in the Basement.
What are the three Ceremonial Masks for? The Owl, Serpent, and Wolf masks are the main quest items. They are used to unlock the final door inside the Observatory on the Second Floor. Placing all three in the door's indentations triggers the game's final sequence.
Is there a point of no return? Yes. Once you place all three Ceremonial Masks in the Observatory door and step through it, you cannot return to the rest of the mansion. Ensure you have explored everything you wish to before proceeding.
