In Abyss School, you have to go through 10 floors. Unlocking each will help you progress in the game. This guide will show you how to solve the Floor 6 puzzle.

Getting the remote and opening the A door

Abyss School Guide, Getting the remote and opening the A door

Go forward into the right corridor. There, you will find a petri dish with a remote control. Use the remote control to pull one of the eggs.

Once finished, head back to the spawn entrance and enter cross-space. Continue forward, then turn right and press the button. This will open the A-door.

Return to the spawn chamber and turn left toward the A door. The desk will have a shelf key. Take the key and use it on the cabinet at one end of the abyss zombie trail.

After gathering the proper goods, return to the A door and breach the wall. Enter the cross-space and press the button at the end of the wall. With this, the main door will no longer be used for egg-pulling.

Open the main door and navigate through the number puzzle

When you open the main door, you will encounter an abyss zombie elite and three corridors. There is a switch marked with a letter in each of the hallways. Switch all three of them so that you may enter more doors in the cross-space on the right side of the spawn door.

Entering each of these newly opened doors shows assigned numbers:

First room: +80
Second Room: +8
Third room: +200
Fourth room: +4000

Add these numbers up to create the passcode 4288. Enter this code to gain access to the next door, which leads to another passcode-locked room. A piece of paper in the classroom holds the correct code: 1053.

Navigating Stained Paper Codes

The second chamber has another closed door, and the passcode is covered in dirty papers. The correct code to punch is 4642.

Then, another pair of abyss zombie elites and more dirty papers will disclose the next passcode, 4216.

More dirty papers in the infirmary will help crack the next code. The correct sequence to punch is 6723.

Trapping the Abyss Zombies and opening the Safe

Abyss School Guide, Trapping the Abyss Zombies and opening the Safe

In the room to your left, you will find an abyss zombie elite caged, and a pressure plate cage. To unlock the door, get the zombie on top of the pressure plate.
Inside the cage, there will be a safe with a code. The code is 4973, which will be required for further progress.
Continue, but do not pull out the eggs. In the following section, another abyss zombie elite will have to be brought onto a pressure plate.
Once the zombie has been trapped inside the cage, the safe can be opened, and you can access the cutters.

Fight the Abyss Anglerfish and Escaping

As the passageway continues, an abyssal anglerfish will ambush it and pray that someone will walk into its path.

Open the cage and lure the abyss zombie elite toward the anglerfish. Once the anglerfish has consumed the zombie, go ahead and cut through the door with the cutters.
