Absolute Pitch Black: With the removal of Minecraft's ambient light, caves and moonless nights turn into a black void. If you don't have a light source, you will be completely blind.
The Dark is Deadly: The dreaded Grue ensures that staying in the shadows for too long is a death sentence. Total darkness now actively hunts you.
Threats in the Fog: A dense and oppressive fog hides bizarre entities. The Cave Dweller lurks in the tunnels, while silent figures watch you from afar among the trees.
Realistic and Terrifying Audio: The sound physics have been overhauled. Every footstep, drop of water, moan, or scream echoes realistically through the caves. The silence has been replaced by an ambient soundscape that will leave you constantly paranoid.
Dynamic Lighting: Holding a torch or lantern in your hand will dynamically illuminate your surroundings, allowing for desperate escapes through the dark when you don't have time to place a torch on the ground.
