"A captain. Does that mean this man was Zero? On his left hand was a bracelet. The number on the bracelet was 0..."
— Junpei, after walking in on the dead captain

The Captain's Quarters is a small escape room entered immediately after going through the Chart room which is past Door 1. It has two rooms, one of which is the communications office, and the other is the actual quarters. It is investigated by Junpei, Ace and Clover.



The office on the left and quarters on the right.

The Captain's Quarters is split into two small rooms: The communications office and the actual quarters. The communications office is entered first, and the Captain's Quarters can be accessed beyond it.

Communications Office

The communications office has a bunch of retro electronic equipment that were used on ships to communicate with each other out at sea. One object of interest is a telegraph key, used to send messages through Morse code. Other objects scattered on the table include a small box of screwdrivers and a long wire.

Captain's Quarters

A door on the right side of the communications office leads to the actual quarters. The dead body of the apparent captain of the ship is in the room, along with a camcorder, monitors showing different areas of the ship, and a bed with a nightstand next to it. There is also a green chair that has a blood stain on the cushion.


Cap dead 1

Could he be Zero?

Upon leaving the wheelhouse, Junpei, Clover, and Ace enter a narrow hallway and open a door. They walk into what appears to be a communications office. Another door connected to the room has a plaque that says Captain's Quarters on it. The group suspects that it is Zero's hideout, and everyone is nervous except for Clover, saying that they have nothing to lose. They walk in to a dead man dressed like a captain. He appeared to have been killed with an axe, as it was sitting right next to him, and he was wearing a bracelet with a zero on the face of it. Junpei comes to the conclusion that the dead man is not the real Zero, as the evidence is too straightforward. Ace leaves to investigate the communications office, leaving Junpei and Clover alone with the dead man.


Clover thanks junpei

Clover hugs Junpei after realizing Snake is not dead.

Triggered by pressing the keyboard in front of the monitors. (True Ending route only)

When Junpei presses on the keyboard connected to the monitors in the quarters, the bottom four screens change into the letters "Z", "E", "R", and "O". Junpei laughs at Zero's idea of a joke and asks Clover if she thinks the dead man is Zero. She says no, and is firm on her belief that one of the players is Zero. Junpei is convinced that the obviousness of the man being Zero is just a trick to mock them. Clover and Junpei proceed to examine the man's body. His bracelet falls off and Junpei comments that the man had a less painful death than Snake. He says that some of his bones were sticking out of his left arm and Clover stops him to ask if he was for sure that the left arm was broken. After Junpei confirms the fact, she starts tearing up and tells Junpei that the body in the shower room is not Snake's. She hugs Junpei and thanks him for giving her the bookmark.

Junpei tells Clover that she should really be thanking Santa for the "leaf words". Clover says that Santa was a subject on the Gigantic and that he was unrecognizable due to Snake's blindness. She explains that there was an experiment in 2018 that was testing the use of the morphogenetic field and that it was called the Nonary Game. The game put the 18 participants (9 on the Gigantic and 9 in Nevada) in a life-or-death situation to make it easier for them to transfer information through the morphogenetic field. She mentions that she and Snake were a part of this experiment and that Snake was on the Gigantic, while she was in Building Q. She then recalls that one girl died, but Ace bursts into the room before she can tell Junpei her name. Ace asks for Junpei's help in the communications office and Junpei reluctantly leaves, mentioning that she should tell him the story later.

A Creepy Smile...

Triggered by pressing the keyboard in front of the monitors. (Axe Ending route only)

If Junpei did not give the four leaf clover bookmark to Clover, Junpei points out that the dead man in the room is not Zero. Clover says that one of them is actually their kidnapper and that they need to find a way out first before finding out the identity of the corpse. While walking away, he sees Clover smile angrily, but thinks his mind is playing tricks on him.

Red File


The ALL-ICE file, completely written in hieroglyphics.

Triggered by obtaining ALL-ICE file.

When Junpei obtains the ALL-ICE file, he looks through it hoping to find information, but neither he nor Ace can read it, as it's written in hieroglyphics. A key card drops out of the file, and it reads "BOTTOM DECK LIBRARY" on it. This turns out to be the Uranus key card used later to access the library. Junpei suddenly realizes that that could be where Alice is kept and tells Ace everything he knows about her history regarding Ice-9 and Gordain (This only occurs if you heard Seven talk about All-ice in the operating room).

Ace thinks for a bit and asks Junpei if he knows anything about CAS. Apparently, it's where the body is frozen using magnetic fields, leaving no time for ice crystals to form, safely preserving the frozen object. Ace suggests that Alice might have been frozen by CAS, and that she is still alive. Even more bizarre, he goes on to say that Alice might have been the dead captain's murderer, as there was no way anyone had access to Door 1 before their group and that Alice would know all of the secret passages on the ship. He then remembers what Seven told him about Gordain's message. Junpei then realizes the Uranus Key Card will give him the answers about Alice.

If the Axe Ending path is followed, Ace only comments on the All-ice file, and doesn't talk about CAS.

The end result of the Morse code puzzle.

Requirements: Morse code chart

This is a really simple puzzle. In Morse Code, a dot means a short tap, and a dash means you hold the button down for a few seconds. Simply do what the Morse code chart says, and you unlock the drawer that was previously locked. This drawer holds the Uranus key and the "Information about Alice" file.

Door Lock

Door Lock

The password to open the door.

Requirements: unique key

To solve this "puzzle", examine the keypad and insert the unique key. 8 lines show up, meaning you have to type in a 8-digit password. Using hexadecimal numbers (A=10, B=11 C=12, etc...), figure out which four numbers correspond to the letters "Z", "E", "R" and "O". The password is 35-14-27-24. Successfully unlocking the door will allow you to escape the room and go back to the central staircase.


  • Another version of the "Morse Code" puzzle is played in the Study.
  • The morse code translates to "35<BT>Z". This likely serves as a hint as for how to solve the Captain's Quarters door (with first 2 digits being 35, translating into Z).
  • In the DS version, after triggering the 'z e r o' display on the True Ending route, when Clover starts to tell Junpei about the morphogenetic field and such, there is a typo. "So... what exacty did they have you guys do?"
  • While examining the bed, Junpei will say that Musashidou's body could have been hidden under the bed. This could also explain why he is never mentioned by Seven and Lotus during the Safe Ending, since Clover probably killed him and hid his body under the bed.
  • As revealed in the True Ending, Ace was instigated by Zero to enter this room. Ace was given a note by Zero which told him that he could win the Nonary Game if he "confessed his sins of 9 years past." Zero said a camera in the captain's quarters was prepared and the images captured by that camera will be streamed through a satellite and distributed across the world. Zero also mentioned that to make Ace's confession more credible, a witness would also be in the room. Instead of confessing, Ace's motive was to kill the witness. Ace knew the layout of the ship since he bought the Gigantic and knew that the captain's quarters was behind Door 1.
