To reach the secret ending in Tenebris Somnia, turn around as soon as the adventure begins and return to the building’s main entrance. Open your inventory there, select Ivan’s apartment key, and use it to leave the building and go outside. According to the available solution, leaving through this entrance completes the secret ending.

- Walk back to the building’s main door or principal entrance.
- Open the inventory when you are at the entrance.
- Choose the key belonging to Ivan’s apartment.

Important route details
The timing is the key part of this solution: the turn back happens at the beginning of the adventure, rather than after exploring the building. The source does not describe a puzzle, conversation, additional item, or alternative route. It also does not provide a separate code or a sequence of button inputs; use the game’s normal inventory command to select and apply the key.
If the exit does not work, check the order of actions first. You should be at the main entrance, have the inventory open, and select Ivan’s apartment key before attempting to leave. The supplied solution does not establish any other prerequisite or troubleshooting method, so no additional requirements can be confirmed from the available information.
What this guide confirms
- Return immediately after the adventure starts.
- Go to the building’s main entrance.
- Use Ivan’s apartment key from the inventory.
- Leave the building and reach the street.
The source supports only this short escape route, so details beyond these actions—such as the exact ending scene, achievement name, controls, or other possible endings—cannot be confirmed here.
