Before you step inside
A few things to know.
Should I start with the demo or the full-game guide?
The game is already released. Our apartment, puzzle and ending routes refer to the full game unless a page says otherwise. If you want to try it first, use the official demo and version guide ↗; demo content can differ from the release.
Will these guides spoil the story?
Walkthroughs reveal the actions and locations needed to progress. Major ending conditions are marked and placed inside disclosures. For the lightest touch, open a guide for your current puzzle or item instead of reading a whole route.
Is this the official Tenebris Somnia website?
This is an independent fan guide. Our editorial desk checks published sources and explains coverage limits; we do not claim a personal playtest. For purchases, downloads and official announcements, visit New Blood’s official game page ↗.
Where can I report a different result?
Send a correction ↗ with the guide URL, game version, platform and the step that behaved differently. Sources and the latest review date are listed at the end of every guide.
