Entropy: How to Open Locked Door Under Cuvas

Once you arrive in Cuvas, keep to the right side and head up towards Klatch Hall.

Standing in front of it, turn left and walk across the wooden bridge.

Then go to the left part of the location along the cliff. You will see a cave and lots of graffiti; go inside, and there you will find the door you’re looking for.

Alternatively: you can keep to the left side when you get to Cuvas and you’ll immediately reach the cliff under the bridge.

You’ll most likely find the first note on your way from Cnothag Forest to Cuvas, in a Ruined House. But if you missed it, you can see this house all the way from Cuvas. Head straight Voidwards.

This location is quite linear: go all the way through the first building, then go inside the second building.

Inside, behind the delusion-disc-TV-thing, you’ll find a staircase.

Go down it, and you’ll end up in the basement. Go to the far wall (an interaction sign will appear), press a button to destroy it, and go straight through the dungeon.

At the end, there will be a table with a skeleton and a note. Click on it and get the first part of the code.

In Сuvas, you can get a quest to restore The Great Transciever. After conducting the investigation (which I won’t describe here to keep the guide short and spoiler‑free as possible) you need to head Voidwards, returning to the quarantine gates near Draenog.

After entering the bunker as part of the quest, clear it out and reach the boss. To the left of him, there will be a door.

Inside, you’ll find a switch; interact with it.

Return to the room with the boss and retrace your steps back to the previous room. To the right, there will now be an unlocked door.

Inside an old friend skeleton will be waiting at the table, along with a note containing next part of codes.

You will be able to find thirt note only after completing Act 1.

You already can see this Ruined House even from Cuvas.

After finishing the quest inside Shaper Fortress, go through the main gates of the location.

If you are doing this for the first time, the credits for Act 1 will start and you will be thrown back to the main menu. Don’t worry, the game isn’t over; load your save, and you will appear after Black Mountains. Turn right and go to the ruined house.

There is only one house inside the location, with a staircase located behind the TV. Go down, break the wall, head to the skeleton, take the note. Usual business.

Return to Cuvas to the cave with locked door. Enter the four required digits in a sequence.

Keep in mind that first number in the note indicates the number under which you need to enter the digit, and second number is the digit you need to enter.

Как видно из моих записок я должен ввести IV – IV – I – III.

Success! Inside, you will find: Old Gloaming Armour and Old Gloaming Helmet.

Beware that the door may close permanently after leaving, make sure to do all your business inside.

This guide is relevant for Entropy Act 1 Version . I actively follow the game and will update this guide if the developers make any changes.

Also, keep in mind that the numbers I showed in the screenshots:
1. Can NOT be entered until all three notes are found (do not try to brute‑force the panel);
2. May not match the numbers in your playthrough.

Thank you very much for using the guide, and a special thanks to the members of the Dread XP Discord server for helping to solve the mystery of this door.
