Hollow Days
Most horror mods in Minecraft chase you down a cave with a screaming entity and a screen full of red. Hollow Days does the opposite. It is a single-player horror mod built around liminal spaces and quiet, existential dread. There are no monsters to fight, no jump scares, and no blood. Just you, an ordinary world, and the growing feeling that something about it is wrong.
That premise alone makes Hollow Days one of the more unusual experiences you can install. It does not want to frighten you with noise. It wants to unsettle you with silence, and it is very good at it.
What Makes Hollow Days Different
Every day the world is a little less sure of what it is supposed to be. That is the core design idea, and it plays out slowly. Nothing will chase you. You are free to play the way you always do: build, explore, sleep. The mod simply asks that you pay attention to what you see and hear.
This is a short scripted experience rather than a sandbox overhaul. You get four in-game days in one world, and then it ends. There is no endless loop, no repeatable content, and no second act. Knowing that going in actually helps the pacing feel deliberate rather than abrupt.
How to Play Hollow Days Properly
- Create a new Survival world and play alone, with the sound on.
- Headphones and a dark room help considerably.
- Do not look things up. It works best if you do not know what is coming.
- Never install it into a world you care about.
The mod changes your world for good, and your builds may not survive it. Treat it like a one-way trip and you will get far more out of it.
Supported Versions and Loader
Hollow Days for Minecraft is built for Minecraft Java Edition 1.21.1. It requires Fabric Loader 0.16.14 or newer along with Fabric API. There is no Forge or NeoForge build, so if you are running a different loader you will need to set up a separate Fabric profile before you begin.
If you would rather skip the manual setup entirely, the foxygame.net launcher handles the whole process for you: Hollow Days appears in its add-on catalog and installs with a single click, matching the correct Fabric version automatically so nothing conflicts with your existing profiles.
How to Install
Installation is straightforward once your environment is ready.
- Install Fabric Loader 0.16.14 or newer for Minecraft Java Edition 1.21.1.
- Place Fabric API in your mods folder.
- Download Hollow Days and drop the file into the same mods folder.
- Launch the Fabric profile, create a brand new Survival world, and play alone with sound enabled.
Do not load an existing save. The mod is designed around a fresh world, and the scripted sequence assumes it starts from day one.
Things to Know Before You Start
While the mod is installed, music is turned off and the title screen panorama stands still. At some point the mod lowers your brightness, and your own setting returns when you leave the world. These are intentional choices, not bugs.
Hollow Days is made for single-player only. Compatibility with mods that change the sky, rendering, or sound has not been tested, so a lean mod list is the safest approach. Shaders and audio overhauls in particular can interfere with the atmosphere the mod is trying to build.
Is Hollow Days Worth Installing?
If you want combat, boss fights, or a monster that hunts you through the night, this is not that mod. Hollow Days is closer to a short atmospheric story you walk through at your own pace. It respects your familiarity with Minecraft and then quietly uses it against you, turning ordinary terrain and familiar sounds into something faintly wrong.
Four days is not a long commitment. Install it on a throwaway world, keep the lights off, and let the silence do the work. When it ends, you will probably want to sit with it for a minute before loading anything else.
