Tenebris Somnia Guide | How to Get All Endings

Tenebris Somnia features four endings, each with its own achievement: SOLVE ET COAGULA, MAGNUM OPUS, VIVUS EX MORTIBUS, and RENUNTIATIO. The first two endings depend on your actions during the final section of the main story, while the other two are hidden endings that require additional steps.

Ending 1: SOLVE ET COAGULA

Progress through the main story until you forge and obtain the Aurifer knife.

Create a manual save before continuing through the final section. This allows you to return to this point later to unlock Ending 2.

Continue toward the Séptimo Arte theater and watch for Relicta ghosts.

Avoid attacking or killing any Relicta with the Aurifer. Instead, run past them and continue through the area.

Progress through the finale until you reach the final boss, Lacuna.

Defeat Lacuna and finish the game to unlock SOLVE ET COAGULA.

The most important requirement is that you must not kill any Relicta with the Aurifer during the final route. Even a single kill will change which ending you receive.

When you encounter a Relicta, focus on avoiding its attacks and moving forward instead of fighting. If you're unsure whether you have accidentally killed one, reload your save from before the encounter to preserve the no-kill route.

Once the ending achievement appears, you can reload your earlier save to pursue Ending 2 without replaying the entire game.

Ending 2: MAGNUM OPUS

To get Ending 2, kill at least one Relicta ghost using the Aurifer. This ending follows the opposite route from Ending 1 and is commonly considered the bad ending. You do not need to kill every Relicta. One confirmed kill with the Aurifer triggers the alternate finale.

Load a manual save from after you obtain the Aurifer, or continue a playthrough where you haven't completed the final section.

Return to the area where Relicta ghosts appear.

Find a Relicta and attack it using the Aurifer.

Make sure you actually kill at least one Relicta; don't just hit it.

Continue through the final area toward the Séptimo Arte theater.

Progress through the alternate finale and defeat Hermes to unlock MAGNUM OPUS.

Unlike Ending 1, this route requires you to use the Aurifer aggressively against the Relicta ghosts. Once you have killed one, you cannot return to the no-kill ending in the same run unless you reload a save from before the kill.

How to Get Both Main Endings Without Replaying the Game

The easiest approach is to create a manual save immediately after you get the Aurifer, before you kill any Relicta.

First, complete the game without killing any Relicta to unlock SOLVE ET COAGULA. Then reload your save and kill at least one Relicta with the Aurifer. Continue through the finale to unlock MAGNUM OPUS.

This saves you from replaying the earlier puzzles and story sections. Just remember that the two routes lead to different final encounters, so you must complete each route's finale separately.

Ending 3: VIVUS EX MORTIBUS

To unlock Ending 3, collect three Iron Crosses by using the Bible to trigger hidden encounters, then place the crosses on the third floor to open a secret route. This ending requires you to complete Endings 1 and 2 first and start a new game.

Unlike the first two endings, you cannot unlock this one simply by changing your actions during the finale. You must complete three special encounters before solving their corresponding puzzles normally.

1. Find the Bible

After completing both main endings, start a new game.

At the beginning of the game, search the ground-floor lobby for the glass table and collect the Bible. This item is essential for triggering the encounters that reward you with the three Iron Crosses.

Keep the Bible in your inventory as you progress. Complete the hidden encounters before solving the associated puzzles through their normal methods.

2. Collect the First Iron Cross

Head to the second-floor apartment and enter the living room. You must perform this ritual before completing the normal TV puzzle.

• Use the Bible in the living room to trigger the hidden encounter.
• Locate the circle of planetary symbols on the floor.
• Stand on the Man/Mars symbol (♂).
• Run counterclockwise around the circle six times.
• Defeat the enemies that appear.
• Collect the first Iron Cross.

Make sure you perform this ritual before solving the TV puzzle. Normally, completing the puzzle removes the Bible from your inventory, so you can't trigger the encounter afterward.

3. Collect the Second Iron Cross

Next, head to the Community Center on the first floor and find the locked projector room.

• Use the Bible on the lock to open it normally.
• Approach the projector-room lock.
• Use the Bible on the lock to trigger the hidden encounter.
• Enter the code 6666 when prompted.
• Defeat the enemies that appear.
• Pick up the second Iron Cross.

Do not open the projector room normally before triggering this encounter. If you solve the lock first, you may lose the opportunity to collect the second cross during that playthrough.

4. Collect the Third Iron Cross

For the final cross, head to Floor 0 and locate the green door leading to the cinematography room. Complete this encounter before entering the Copper Key-locked door.

• Enter the cinematography room.
• Use the Bible to trigger the hidden encounter.
• Find the camera mounted on the tripod.
• Connect the yellow RCA cable to the camera.
• Switch between the camera channels until enemies appear.
• Defeat the enemies and collect the third Iron Cross.

Once you have collected all three Iron Crosses, you can proceed to the secret area.

5. Unlock the Secret Route and Defeat Amy

Return to the third floor and find the blue door to the left of the elevator. Look for the marked wall or poster where you can place the Iron Crosses.

Insert all three crosses to unlock the secret doorway, then enter the newly accessible area.

Continue through the secret route and prepare for a boss encounter against Amy, a character associated with the FAITH games. Defeat Amy to complete the secret route and unlock VIVUS EX MORTIBUS.

If the secret doorway doesn't open, make sure you collected all three Iron Crosses in the same playthrough.

Ending 4: RENUNTIATIO

You must complete Endings 1 and 2; SOLVE ET COAGULA and MAGNUM OPUS, before attempting this hidden ending.

• Start a new game.
• After the opening sequence finishes, look around the ground-floor lobby.
• Find the building's glass entrance door on the left side of the room.
• Open your inventory and select the Apartment Key.
• Use the key on the building's front entrance instead of taking the elevator to Ivan's apartment.
• Julia will leave the building, triggering the ending.

The key is to leave immediately instead of continuing through the normal story. You do not need to collect the Bible, solve the apartment puzzles, or fight the final bosses for this route.

Once Julia exits the building and the ending sequence plays, RENUNTIATIO unlocks.

Final Thoughts

Ending 4 is a relatively quick ending to obtain in Tenebris Somnia once you've completed the necessary prerequisites. The key is to finish Endings 1 and 2 first, start a new playthrough, and use the Apartment Key on the building's front entrance. This route lets you skip the usual progression and avoid unnecessary puzzles or encounters.
