The Black Monolith Room is located in the Natural Region. It is considered the most famous yet infamous room in FEZ, and can be accessed at the Nature Hub after lowering the sea level.
Appearance[]
When entering the room for the first time, it's introduced as an empty room, with a number of unlit red candles around the place. Viewing the empty ground in first-person reveals a marking similar to the Polytron Logo. After solving the first half of this room, a black, rectangular prism serving as the Monolith will appear above the empty area.
Collectibles[]
There is a hidden Heart Cube that requires the player to be in New Game Plus mode and have a certain Treasure Map to obtain. It can then be collected after following 2 steps:
- There is a marking on the ground only visible using first-person that matches with a certain map. Follow the map to the indicated position and execute the Tetromino sequence on the map. This will summon the titular Black Monolith.
- Go to the position on the ground directly opposite of the map's indicated position and input the following code to reveal the Heart Cube: (↓ ↓ LT RT RT [Jump] ↑)
Trivia[]
- Since part of the map is burned off, the FEZ community had to solve the missing half of the puzzle using brute force code-cracking, as there seemingly was no in-game solution to the map.[citation needed] This makes the Black Monolith Room one of the most impossible and daunting puzzles without a guide.
- The logic behind the final code for this room has yet to be solved.
