In Atomic Heart, door codes and passwords allow you to open new passages or secret rooms where chests containing valuable materials and blueprints are hidden. Some of these locks do not need to be picked according to the story, so the game does not indicate the locations of the necessary combinations. In this guide, we’ll show you where to find all the secret locks and tell you how to open them.

The “Vavilov” Complex (Plot-based):

  • Where is the code? It’s on the floor, 10 meters from the door.
  • Combination: A small square (4 dots) in the upper left quarter of the lock.

VDNKh (Optional):

  • Where is the code? It’s written on the board in the next room.
  • Combination: A square slightly larger than the first one, in another part of the disc. Behind the door is a valuable blueprint.

Plisetskaya Theatre (Story-based):

  • Where is the code? On a piece of paper next to the electrician’s body.
  • Combination: Three separate dots. The dead electrician will tell you the order to press them (use the dialogue through the glove).

Pavlov Complex / Hospital (Optional):

  • Where is the code? It is drawn in the form of circles on the wall with bloody fingerprints.
  • Combination: Five buttons in a specific order (see screenshot/video). Inside the room is a huge amount of loot and the missing blueprints.
