A downloadable mod

Tenebra is a psychological horror game that takes you on a journey through a beautifully moody and often dreadful world that reveals itself as you progress. It embraces sadness and despair as you descend into darkness.

Your goal: search for clues and find out who's behind a disturbing spree of murder and violence. Tenebra's visual style is inspired by films from the silent movie era.

Playing Tenebra:
In case you get stuck...
All you can do is move, look/investigate and crouch. Crouching is not only required to move through tight spaces. Enemies will also have a harder time seeing you.

There is NO 'use' key.

Tenebra relies heavily on HDR. Please make sure to enable HDR (Full) under Options -> Video -> Advanced. And while you're there please also disable Motion Blur.

Hello, so I followed the instructions on downloading this and it only worked for me when I restarted my computer, not just steam. I was about to be disappointed but now I can play! looking forward to it

Glad you got it working!

Fantastic stuff, I trawl through the horror sections on these websites for great little experiences like this. Agree with it being hugely atmospheric, love how a lot of the horror crept up on you or was just out of sight unless you were having a good snoop around like I always do. Really nice work!


Visually stunning, incredibly immersive and the atmosphere is amazing. I covered this as part of my weekly Indie Freebies piece for Gaming Respawn: http://gamingrespawn.com/indie-game-spotlight/16854/indie-freebies-tenebra-niva-anxiety-lost-night/
