After killing the boss of the supermax prison, you get a key. It allows you access to that room connected to the prison courtyard.



Northwest of the timer room, bottom of the security room, there's a locked door saying you need the codebearer ritual. There are four enemies around it. Make sure you know where it is.



To unlock the door in the timer room, you need to imput a code on the rocks. to activate the rocks, you need to do a ritual involving the weapon symbols in the room, and killing an enemy behind the codebearer ritual room.

Basically, it goes like this :

1) wait for the timer to reset (to have your full 5 minutes).

2) Choose any "weapon" symbol on the ground. It has four numbers. Start with the hammer if present.

3) Just on top of the timer room, there's a checkpoint. Change your weapon and reset your stats to match the weapon symbol and the numbers.

4) Go to the symbol you choosed and activate it. It will turn green.

5) Rush to the locked ritual ground. You can now unlock it. Remember : you run faster with an empty stamina gauge.

6) Inside, there's a scythe enemy. Kill it. It will reveal a rock symbol. Memorize it (or screenshot it)

7) Return to the checkpoint atop the timer room and activate it, to be able to choose another symbol.

8) Go back to the timer room. Pick another weapon symbol, and repeat steps 3 to 6.

9) Hit the rocks right of the weapon symbols you chose until they display the corresponding rock symbol you saw when killing the scythe guy.

10) If you managed to do all that for the three weapon symbols, go for the door right of the timer room. It's really hard to do since you'll have very limited stats, you're likely only going to have two.
If you got only two, imput them first, and then try each symbol on the last rock. Make sure to check the door with each symbol, as there's nothing else that's going to tell you if you got it right.

11) Unlock the door and enjoy your loot.

You'll notice, around the timer, there's some codes too. Those are linked to the symbols you have to put on the rocks. See below for a list of decoded ones, and feel free to add missing ones you'd find in the comments with a full screenshot.
I think I have all of them, but I may be wrong.


Please note, to activate the rocks, you have to go through the cycle at least once and kill the scythe guy.

Code order : " . " -> " : " -> " - "
