Tenebris Somnia: VIVUS EX MORTIBUS Ending Steps

The VIVUS EX MORTIBUS ending in Tenebris Somnia is unlocked by meeting two prerequisites before you even start the run, then following a strict sequence of Bible interactions and puzzle solutions. You must have already completed both the SOLVE ET COAGULA (Final 1) and MAGNUM OPUS (Final 2) endings on your save file. Once both are done, begin a completely new game. From that point, the route is linear if you follow the steps below in order.

Prerequisites and Overview

• Finish Final 1 (SOLVE ET COAGULA): Obtain the Aurifer without killing any enemies, then proceed to the final boss fight.
• Finish Final 2 (MAGNUM OPUS): Obtain the Aurifer while killing at least one Relicta.
• Start a new game after both endings are registered. Do not continue an old save.

The VIVUS EX MORTIBUS path is longer because it requires replaying a significant portion of the game, but the key is using the Bible at four specific moments and changing one lock combination and one TV channel. Missing any of these steps will lock you out of the ending, so save before each interaction if you want a safety net.

Step-by-Step Route

1. First scenario – pick up the Bible. In the opening area, look for a Bible lying on a table. Pick it up and keep it in your inventory. This item is required for all later Bible uses.
2. Second-floor apartment – use the Bible before the TV puzzle. Go to the apartment on the second floor. Before you solve the television puzzle, use the Bible. A cinematic will play; watch it carefully because it shows the correct solution for the puzzle. After the cinematic, solve the TV puzzle exactly as shown.
3. Cultural center – use the Bible before the padlock. Later, go to the cultural center. Before you interact with the padlock puzzle, use the Bible. Then enter the code 6666 on the lock. This code is different from the normal solution, so the Bible use is what makes it valid.
4. Floor 0 – use the Bible in the shotgun man's room. Much later, when you reach Floor 0, find the room containing the man with the shotgun. Use the Bible there. Then connect the yellow cable and change the TV channel repeatedly until enemies appear. Kill those enemies.
5. Third floor – blue door with three red crosses. Go to the blue door on the third floor, to the left of the elevator. On the right-hand wall in the street, place the three red crosses, then enter the door. This triggers the VIVUS EX MORTIBUS ending.

Common Pitfalls

• Using the Bible after solving a puzzle instead of before will not trigger the required scripted event.
• Entering the normal code on the cultural center padlock instead of 6666 will lock you out of this ending.
• Killing enemies in the Floor 0 room before changing the channel and spawning the correct ones may break the sequence.
• Placing the red crosses on the wrong wall or entering the wrong door will not advance the ending.

If you follow these steps on a fresh save with Final 1 and Final 2 already completed, you will reach the VIVUS EX MORTIBUS conclusion.
