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 4 puzzle.
Solving the Flask-Beaker Puzzle
When you enter the chamber, you will see four colored flasks and three colored beakers. To proceed, go to the room on the right, where you will find a lever. Pull the lever to activate the door.
After that, take the flasks and head to the left side of the chamber, where you'll see a white shelf. Arrange the colored flasks in this order:
- Red flask > Upper left
- White flask > Upper right
- Green flask > Bottom left
- Blue flask > Bottom right
Once the flasks are in place, move to the right side of the chamber to get the cutters. Use these to cut the chains, then pull the lever to power the second module to the door.
This will open one of the cages harboring the abyss zombie elite. Inside the cage, you'll find a key; grab it and return to the left side of the chamber. Use the key to unlock the door.
Once past the door, you'll find another lever and the blue flask needed to solve the puzzle for the beakers. Place the beakers in the following order:
- Purple beaker > Upper left
- Black beaker > Upper right
- Orange beaker > Bottom left
- Light blue beaker > Bottom right
Next, take the hammer from the open cabinet on the beaker shelf and use it to shatter the hole in the wall to the right. This will disclose the final lever required to operate the door. Pull the lever to progress to the next room.
Dealing with Abyss Zombies and Bolt Cutters
When you enter the next chamber, you'll discover a save table with an abyss zombie to the left and another room to the right.Wait for the abyss zombie to wander to the left side of the chamber before rapidly entering and grabbing the bolt cutter component.Next, proceed to the area on the right, where you will notice purple dots on the floor—these are pulling eggs, and walking on them will instantly kill you. Avoid them as you walk around the table to get the second bolt cutter piece. With the bolt cutters in hand, cautiously navigate the hallway, avoiding the tugging eggs.
Cleaning Up and Using Codes
The next room contains an Abyss Zombie Elite and two bathrooms. Head towards the Abyss Zombie Elite and take the cleaning sponge from the petri dish. Then, go inside the men's restroom and take the detergent.
Open the stall and use the sponge to wipe the discoloration off the wall. Once the wall has been cleansed, the code R X D. will be revealed.
This code is applied to the padlocked stall in the women's restroom. Inside the stall, take the key to the main room's electrical box and use it. This will disclose the lever.
Pulling this lever frees an abyss zombie from the enclosed room. While the zombie is roaming, take the hammer from the women's restroom and shatter the hole in the wall if you haven't already done so.
Enter the hole in the wall and wait for the abyss zombie to be consumed by the tugging egg. Crouch under the zombie and collect the passcode from the safe, which will display the code 2 9 9 9.
To proceed, enter this code on the main door, but be careful not to pull any eggs along the route.
