Revision 1

Voice of the Nightmare is the fourth Nameless Hospital ending. It combines the hidden Nightmare Voices note with two Experiment clues and requires three Jigsaw pieces.

Enter the anomaly through The Hospital: at Hethereau Municipal Hospital on Onion Road in Illusion Town, turn left from reception into the stairwell. Speak to the Nameless Client facing the corner and choose "(Close Eyes)".

Reach the hidden upper room

Bring Aurelia, Nanally or Esper Zero to reach the hole in the ceiling. Take the elevator to 2F and follow the corridor right, then left at the windows and blood-marked wall. If the floor floods, enter the maintenance room near the next bloody wall and shut the water valve. In the room marked by a red glowstick, flip the switch if necessary and take the 2F Keychain from the bulletin board.

Leave that room, turn left, then right at the corner. Let the Bandaged Monster move away before following it. Enter the second door on the right and close it. Jump through the broken wall into the room with the ceiling hole.

Aurelia can double jump onto the I.V. stand and then through the hole. Nanally can use her wall-run skill toward the opening. Male Esper Zero can double jump onto the stand and use his Esper Skill toward the corner. Female Esper Zero can jump from the lockers, use her Esper Skill and switch characters at the jump peak before double jumping through. Skia offers another route: on 3F, hold dash to slip through the barred door.

Assemble the three Jigsaw pieces

In the hidden room, inspect the blue canister beside the desk note for the first piece. Return to 3F, collect the North District Key beside the elevator and assemble the piece on the Jigsaw table. Enter the revealed western door and walk through the illusory wall. Read the desk notes repeatedly until you receive V???'s Notes.

Return to the table. Use the eastern exit and enter the room on the right for a second piece in a sealed canister. Assemble it and defeat the enemies. Leave east again, wait out the Bandaged Monster and follow the corridor to its original position. Turn right and enter the first room on the right for an Experiment clue.

Enter the room across the hall and inspect the canister at its right end to make Mysty follow you. Leave, turn right and take the first hallway left, rather than returning directly to the Jigsaw table. Enter the first room on the right and inspect the leftmost canister on the table to turn Mysty into the third piece. Return to the Jigsaw table and assemble it.

Open the bookshelf door

From the Jigsaw room, leave east, continue to the far end of the corridor, turn right and enter the second door on the left. At the switch between the bookshelves, tap twice quickly, then tap once four times with about one second between taps, then tap twice quickly. Inspect the computer inside the hidden room for the final clue.

Use the projectors

Return to the Jigsaw room and leave south toward the elevator. Go to the video room behind reception on 2F. Place Nightmare Voices Clue (V???'s Notes), Anomaly Experiment Clue III and Anomaly Experiment Clue VI on separate projectors to trigger the ending.

Rewards

The first clear awards 50 Annulith and 5,000 Fons. A safe in the hidden upper room also contains 50,000 Fons.
