Unlocking the Underground of the Mansion in Blue Prince is a key objective for every enthusiast of puzzles. This hidden area grants access to the elusive Room 46, where your final challenge awaits before you complete the game.
Reaching the Underground can be achieved through various paths, each offering differing levels of complexity and engagement. Regardless of which method you choose, the effort is sure to be rewarding.
Here’s a comprehensive guide on how to access the Underground of the mansion in Blue Prince.
Five Points of Entry to the Underground in Blue Prince
To access the Underground, five distinct entry points are available. Feel free to explore any of these routes or combine them for a more rewarding experience. However, keep these critical points in mind:
- Key Requirement: The main sections are secured behind locked doors. You will need the Basement Key to gain entry.
- Key Dynamics: Once you unlock a door, it remains open; however, the Basement Key resets to the Antechamber at the beginning of each play session.
Below are the five entry options you can use to reach the Underground:
- Foundation Elevator (1)
- Cliffside Exit (3)
- Fountain Entrance (5)
- Catacombs (6)
- Torch Chamber (7)
1. Foundation Elevator
The Foundation Elevator serves as one of the simplest access points. To successfully use it, follow these guidelines:
- Place the Foundation permanently within the Manor, ensuring it is positioned correctly. This grants steady access to the Underground.
- Situate the Foundation just past the Entrance Hall, allowing a quick trip underground with minimal effort.
2. Cliffside Exit
The Cliffside Exit offers another route, although you will need a Power Hammer to clear obstacles and destruct weakened walls. If you possess this tool, this route can be quite effective.
3. Fountain Entrance
For those who prefer the Fountain Entrance, first ensure the water is drained. After using the Basement Key on the door, you must navigate a mine cart obstructing a narrow passageway by either pushing or pulling it aside to progress.
4. Catacombs
Accessing the Catacombs requires some randomness and strategy. Here’s a step-by-step breakdown:
- Open the Garage Door to establish permanent entry to the West Gate Path.
- Interact with the shed to check if the Catacombs can be drafted as an option.
- Solve the Chapel puzzle, utilizing the clues provided to pave your way to the Underground.
5. Torch Chamber
Your last entry point is through the Torch Chamber, but only after activating all four Blue Flames. Once completed, an elevator will appear:
- Use the elevator to access a narrow tunnel near the Chess Puzzle.
- Ascend the spiral steps to reach the Underground promptly.
Be sure to take your time as you navigate these puzzles, especially those found in the Gallery. Advance into the Underground at a pace that feels comfortable for you.
