Uncover hidden entrances, solve intricate puzzles, and master the secrets of the Underground as you work to unlock Room 46. Whether you’re seeking the elusive Basement Key or plotting the most efficient route through the Foundation, this walkthrough reveals every twist, shortcut, and secret chamber lurking beneath the estate’s surface.
How to get the Basement Key in Blue Prince
To get the Basement Key in Blue Prince, you must first reach the Antechamber, which is the only location where the key appears. However, entering the Antechamber requires solving a puzzle: you need to find and activate three hidden levers located in the Grand Hall, Secret Garden, and Greenhouse. Once all three levers are pulled, the doors to the Antechamber will unlock. Inside, you’ll find the Basement Key prominently displayed on a pedestal in the center of the room-no further puzzles required. After picking up the key, you can use it to unlock the basement door via the Foundation elevator or the well beneath the Fountain if it has been drained. If you don’t use the key before the day resets, you’ll need to return to the Antechamber to retrieve it again, but any doors you’ve unlocked will remain open for future runs.
To get into the Basement, you’ll need to find the Basement Key. Happily, there’s a short answer to how to get the Basement Key: reach the Antechamber.
Reaching the Antechamber is a much longer process, though. You’ll need to find (at least) one of the three levers that open the Antechamber doors and then draft a path to that door.
Once you do that, you’ll pick up the Basement Key. The Basement key is your main way into the Basement. Even if you (eventually) find other paths in, you’ll still the Basement Key at least once.
How to use the Basement Key in Blue Prince
To use the Basement Key in Blue Prince, first acquire it from the Antechamber, which you can access by unlocking its doors via levers found in other rooms around the estate. Once you have the key, head to the Foundation and activate the elevator by drafting a room with a door facing the correct wall and pulling the hidden lever-this will lower the lift, granting access to the Basement door. Use the Basement Key to unlock this door and enter the Underground area. The key can also be used on a second Basement door beneath the Fountain, accessible after draining it using the Pump Room. Note that the Basement Key is consumed upon use, and any door you unlock will remain permanently open for future runs.
The easiest (well, relatively) way to get to the Basement is through the Foundation. You’ll need to draft it, move the lift down into position by revealing a hidden crank on the back side of the wall, and then take the elevator down where you will find a Basement door. To get that open, you’ll need the Basement Key (see above).
As you explore, you’ll find other ways into the basement like through the Cliffside Exit (if you have a Power Hammer), the Fountain (after you drain it), or the Tomb (in a roundabout way), but the Foundation is the most straightforward.
Full Basement and Underground map in Blue Prince
The Basement and Underground in Blue Prince form a sprawling, interconnected area beneath the mansion, crucial for progressing toward the elusive Room 46. To access the Basement, you must first obtain the Basement Key from the Antechamber, which is unlocked by solving lever puzzles in various rooms. Once you have the key, the most direct route is through the Foundation Elevator, though alternative entrances exist via the Fountain, Cliffside, and Tomb, each with their own requirements and shortcuts. The full map-visible in the Reservoir’s rotating gear room-reveals nine key locations, including the Foundation Elevator, secret passages, and puzzle chambers like the Torch Chamber and the Rotating Gear room, which are essential for unlocking further progress. Navigating the Basement involves solving pallet jack puzzles, clearing obstacles like the Mine Cart, and manipulating the environment to reach hidden pathways, all while gradually unlocking permanent shortcuts and uncovering secrets deep within the Underground.
The Basement is part of a larger Underground complex in Blue Prince. You can find a complete map in the Reservoir’s rotating gear room, or see it below:
There are nine locations labeled on the map:
- Foundation elevator. This is the elevator in the Foundation that will bring you to the main Basement Door.
- Concealed Entrance. This is a hidden door that you open by solving the pallet jack puzzle in the Basement.
- Cliffside Exit. Outside of the house, go past the Fountain and down the stairs to where the blue braziers are. To the right, there’s a boarded up tunnel. If you have a Power Hammer (Sledgehammer Battery Pack Broken Lever in the Workshop), you can smash your way through. This opens a new path into the Basement.
- Mine Cart. The Mine Cart is just an obstacle that you can’t move from the Reservoir side. You’ll find a note about it in the Gemstone Cavern. To move it out of the way, you’ll need to solve the puzzle in the Tomb
- Fountain Entrance. With a bit of work, you can drain the Fountain in front of the house via the Pump Room. Doing so will reveal a new set of stairs and a new Basement door (that you’ll need the Basement Key for).
- Tomb Entrance. The Tomb is an Outer Room that you can draft once you unlock the West Gate Path. Inside, you’ll need to interact with the statues in a specific order to open a path to both the Mine Cart and the Reservoir.
- Torch Chamber. The Torch Chamber is an odd room that both relates to the larger Sigil puzzle and has torches you can light if you have the means (like with a Burning Glass made with a Magnifying Glass and a Metal Detector in the Workshop).
- Rotating Gear. This is your last puzzle to solve before reaching Room 46.
- To North Lever (and Room 46).
Basement walkthrough in Blue Prince
The Basement in Blue Prince is a pivotal area packed with intricate puzzles and multiple objectives, serving as a gateway to Room 46 and deeper sections of the Underground. To access the Basement, you must first acquire the Basement Key from the Antechamber, then use it to unlock the main Basement door, typically reached via the Foundation elevator. Inside, you’ll encounter a series of obstacles, including pallet jack puzzles that require you to create bridges and pathways to reach high buttons and hidden passages. Progressing through the Basement involves solving these spatial puzzles, clearing the mine cart through the Tomb puzzle, and ultimately tackling the Rotating Gear puzzle, which is essential for unlocking Room 46. Along the way, you can also drain the Reservoir to uncover hidden chests and explore optional routes like the Torch Chamber and various secret entrances, making the Basement a complex hub of interconnected challenges and rewards.
Since the Basement is part of the larger Underground, there’s a lot going on down there. There are also multiple goals you can achieve.
The most obvious is reaching Room 46. For that, you’ll have to:
- Solve the Tomb puzzle by drafting the Tomb in the Outer Room and visiting the statues in order, and then move the Mine Cart out of the way (for later)
- Solve the Basement’s pallet jack puzzle and open a path across the tops of the boxes to reach the Concealed Entrance
- With the Mine Cart out of the way, you can solve the Rotating Gear puzzle to.
- Reach Room 46.
While you’re down there, though, you can also:
- Drain the Reservoir via the Pump Room to get at some chests at the bottom.
- Explore the Torch Chamber and its Sigil puzzle.
One final note: The elevator you unlock by lighting the four braziers isn’t connected to the Underground or the Basement. That’s its own area, the Precipice, with its own puzzle – the chess puzzle.
What secrets does the Basement hold in Blue Prince’s mysterious estate
The Basement in Blue Prince’s mysterious estate is a sprawling, puzzle-filled labyrinth that serves as the gateway to some of the game’s deepest secrets.

Beyond these tangible secrets, the Basement’s design encourages players to experiment with the estate’s shifting layout, rewarding those who uncover its hidden mechanisms and master its interconnected rooms. The true depth of the Basement lies not just in its physical puzzles, but in the way it ties together the estate’s lore and the player’s journey toward the heart of Blue Prince’s enigma.
What is the significance of the cryptic note found in the Antechamber
The cryptic note found in the Antechamber of Blue Prince’s estate is significant because it serves as a pivotal clue for progression. The note states that “you must go below before you can go forward,” directly hinting that players must explore the Basement before advancing further in the game. This message not only guides players toward the next step in their journey but also reinforces the estate’s theme of hidden depths and layered secrets, making the Antechamber a crucial narrative and gameplay crossroads.
