The estate of the Blue Prince is scattered with Antechamber levers, the function of which has everything to do with the unlocking of the sealed doors within the Antechamber. These levers must be activated for gaining access to the Antechamber and heading towards Room 46.
These levers can always be found in the same designated rooms, but their exact location changes based on the changing architecture of the house. Each room also has its own individualized puzzle or mechanic, so tracking down these levers is doubly complex. Below is a guide to all Antechamber lever locations in Blue Prince, and how to trigger open the Antechamber.
How to Unlock All Antechamber Doors in Blue Prince
Main Lever Locations:
- East Door: Complete the Moon statue puzzle in the Secret Garden.
- South Door: Repair the broken lever in the Greenhouse.
- West Door: Find the lever behind the locked doors in the Great Hall.
Additional Levers:
There are more levers hidden throughout the estate, including one for the north-facing door and others linked to each cardinal direction.
Reaching the North Door:
Upon entering the Antechamber, it might appear you’ve arrived at Room 46. However, as with most things in Blue Prince, there’s another twist. To fully unlock the Antechamber and open the north-facing door, you’ll need to locate an additional lever hidden deep within the Inner Sanctum beneath the house.
Secondary Antechamber Lever Locations in Blue Prince
Each Antechamber door, including the one leading to Room 46, is linked to a secondary door hidden somewhere within the estate. To fully unlock these paths, you’ll need to find and activate the corresponding secondary levers:
- East Door: Behind the first “secondary” door in the Mechanarium. This area can feature up to eight doors, with the first four leading to a connected room. If no such connection exists, like at a dead end, the Mechanarium generates “secondary” doors pointing in diagonal directions.
- South Door: Hidden behind a breakable wall in the Weight Room. Use a Power Hammer (crafted from a Sledgehammer, Broken Lever, and Battery Pack) to smash the wall behind the punching bag.
- West Door: Located behind a destructible wall in the Secret Garden. Break through the brick wall near the valve handwheel with the Power Hammer to reveal another valve. Turn it to reverse the arrow directions and uncover the secondary lever.
- North Door: Concealed behind the throne in the Throne Room. Access this area by locating a secret floor plan hidden somewhere on the estate.
