Video Cemetery - How to Unlock and Rewards

Activating the Spacetime Projector in the alley makes a door to an Anomalous Realm appear, so go through the door to move to the Anomalous Realm. Reach the deepest Spacetime Projector while checking the footage at each location to complete the quest.

There is a Spacetime Projector in the room at the end of the hallway, so check the footage. Aligning the film's playback point with the red part restores the broken staircase, allowing you to go to the 2nd floor.

Move to the 2nd floor room where you'll find a Spacetime Projector. Turn off the projector. Turning off the projector causes the closed door to disappear, allowing you to pass through.

There is a Spacetime Projector in the next great hall, so check the footage. Aligning the film's playback point with the red part restores the broken staircase on the left, allowing you to go to the 3rd floor.

There is a blue light in the 3rd floor hallway, so approach it and examine the "clue". Examining it makes a Spacetime Projector appear, and turning off the projector causes the closed door to disappear, allowing you to pass through.

Entering the room on the left side of the 3rd floor causes an enemy to appear, so defeat it. Defeating and containing the enemy earns you "Failing You, Heavy in My Heart".

After defeating the enemy, check the footage of the Spacetime Projector in the room. Aligning the film's playback point with the red part opens the door of the room you're in and the door of the room on the opposite side.

Return once to the 2nd floor great hall and check the footage of the Spacetime Projector. Aligning the film's playback point with the red part restores the broken staircase on the right, allowing you to go to the 3rd floor on the right side.

The room on the right is open to the 2nd floor, and there is a blue light in the hallway, so approach it and examine the "clue". Examining it makes a Spacetime Projector appear, and checking the footage and aligning the film's playback point with the red part restores the staircase descending to the 2nd floor.

Moving to the 2nd floor causes 2 enemies to appear, so defeat them. After defeating them, return to the Spacetime Projector in the 2nd floor great hall again.

Return once again to the 2nd floor great hall and check the footage of the Spacetime Projector. Aligning the film's playback point with the red part restores the central walkway on the 3rd floor. Move to the 3rd floor from the room on the right side of the 2nd floor where you fought the enemies, and head to the room beyond the walkway.

There is a blue light in the central room of the 3rd floor, so approach it and examine the "clue". Check the Spacetime Projector that appears to complete the quest. Proceeding through the hallway in front of you returns you to the original alley.
