Atomic Heart has only three code-locked doors. The first two are related to the story, while the third is optional and exceptionally difficult to solve. If you can't figure it out on your own, here's a solution.
Atomic Heart , Mundfish 's latest RPG-style shooter, features four types of locked doors: finger-snap locked doors, colour-matched dots locked doors, pin-pick locked doors, and code-locked doors.
There are only three locked doors that require the code throughout the game. The first will be in the game's opening section; the second will be inside the theatre, and if you don't know how to solve this one, check out our guide on how to unlock the code-locked door in the theatre section .
The third will be optional and not related to the story, but if you are a completionist who wants to collect everything while playing games, then this locked door will definitely catch your attention because it is located in a very visible location and the code for this door is nowhere to be found.
Where is the door code in the Pavlov complex?
You will have to fight your way through the vast bulk of enemies once you reach the Pavlov Complex in Atomic Heart as part of the main story. You will eventually come across the room with the code-locked door, and if you scan the area, you will see that there are a bunch of chests inside that room, but you will not find the piece of paper that holds the code or any other document anywhere inside this level.
This is due to the code being in the level rather than the document. When you get to the door, look at the bloody palm prints on the door and the pool of blood on the floor. This will be the key to unlocking this mystery.
If you follow the blood trail, it will lead you all the way to the complex's lower level. Make sure, however, that you only pursue this mystery after you have defeated all of the enemies in this section. Follow the blood trail until you reach the room with a circle of bloody palm prints. Check out the image below if you're not sure where this room is.

If you align yourself exactly as shown in the image above and look at the circles, you will see the code written right in front of you. Memorize the positions of the circles before returning upstairs to enter the code and unlock the door. There are five chests with a lot of loot inside the room. See the image below for instructions on how to enter the code.

The developers went to great lengths to conceal this code, so we had hoped to find something special in those chests, but aside from some upgrade material and ammo, nothing special can be found once you finally solve this, arguably the most difficult puzzle in the entire game.
