Tenebris Somnia is one continuous descent through a single apartment block and film school. This Tenebris Somnia guide is split by the wall you are stuck on: the first room, the puzzle that blocks a door, or the fight on the other side.

Start here

  • Beginner guide — your first ten minutes, the four health points, and how to work out a puzzle you are stuck on.
  • Full walkthrough — every floor from Iván's apartment to the finale, in the order you meet them.
  • Demo walkthrough — what the free demo actually contains, and both of its puzzles.
  • Controls — keyboard, mouse and gamepad bindings, plus the actions that have no button at all.

Route and puzzles

  • All puzzles — every puzzle in the game, grouped by the kind of thinking it needs.
  • Bottle puzzle — match the pitch of the glass pitcher to the bell behind the bar.
  • TV puzzle — power the remote on Floor 3, then read the answer off the Floor 2 set.
  • Picture puzzle — rebuild the torn Devora poster and fill the empty bedside frame.
  • Photo puzzle — develop the print in the darkroom and place the four poem panels.
  • Floor puzzle — the pressure plates, the lead fly tiles and the elevator colour order.

Fights and endings

  • All bosses — every encounter in the game and the single rule that wins it.
  • Obscuratus — the candle-headed first boss on Floor 2.
  • Vitria — the tentacle boss in the film school and its mirror phase.
  • Final boss — Lacuna, Hermes and the church fight on the street.
  • All endings — the four endings, what decides each one, and why there is no New Game Plus.
  • Secret endings — the walk-out ending and the three Iron Crosses route.
  • Wrench Queen — finishing the whole game with the wrench and nothing else.

Weapons, items and saving

  • Weapons and combat — the four weapons, where each one is, and how fights actually work.
  • Item locations — every key item, listed by the floor it sits on.
  • Silver key and bottle — getting the key from Sanguis and filling the bottle from three flames.
  • Moonlight — finding the moonlit window and turning it into purified water.
  • Save points — how the flames work and which three of them you have to spend.
