Meetings and Essential Tools

Abyss School Guide, Meetings and Essential Tools

Go right to the abyss zombie for bolt cutters, then left to another for a hammer. Knock over the table pot to get a filthy battery. Break the damaged wall with a hammer and look for a sponge and detergent. Cleaning the stain next to the safe reveals the code 2339; open it to get a valve.

Back in the main area, swim in the blue pool to place the valve. This pool can clean unclean batteries. Walls in the steam room will display A B X. The Abyss Zombie Elite locker can be opened with this code. With the switch, release the two zombie elites and imprison them in the cage to set a trap.

Get the red spectacles by opening the door near an abyss zombie's path in the main area with bolt cutters. Red glasses and a cleaned battery go on the statue. Use 7155 to open the red safe and get the blue spectacles. Do it again:

Find 8189 in blue glasses. Open blue safe for green glasses.
Green glasses show 9488 > Open green safe for electrical box key.
Return to the main area after unlocking the electrical box and activating the trap.

Traps And Safe Codes

Abyss School Guide, Traps And Safe Codes

To guide the abyss zombies to a tugging egg, knock over two blue pots. Once imprisoned, go under the zombie and cage all three abyss zombies with wall buttons. This unlocks a gear-containing safe. Put the gear in the main area to set another trap.

Now, enter the hole near the blue pool and follow the abyss zombies through the maze. Use the red switch to summon a tugging egg that devours the abyss zombie elite. Undergo and reach safety.

Grab the cutter in the petri dish at the abyss zombie's trail's end.
Use the safe code 4274 to retrieve the closet key.
Get the red glasses from the closet.
Red glasses on the statue reveal 3452; enter this code into the red safe to get a remote. Activating the remote connects an abyss zombie's trail, letting you safely pass the anglerfish.
