About this project

What does Cosmic Horror add?

Two Moon

The moment you create a new world... everything changes.

Cosmic Horror is a psychological horror mod inspired by the works of H.P. Lovecraft. Instead of filling your world with constant monsters, it slowly twists the Minecraft you already know into something that feels wrong.

From the very first second you spawn, the world is no longer the same.

What to expect

  • 10+ unique events that can happen naturally while you play.
  • Rare encounters that become more disturbing the longer you survive.
  • Creatures that silently observe you from places they shouldn't exist.
  • Reality glitches, time distortions, strange moon events, and impossible occurrences.
  • Darkness that becomes more than just the absence of light.
  • Hidden mechanics that react to your actions and surroundings.
  • Unpredictable jumpscares used sparingly to keep you constantly on edge.
  • Secrets, hidden lore, and mysteries waiting to be discovered.
  • No scripted story.
  • No fixed progression.
  • Every world creates its own horror experience.

You never know when something will happen...
only that it eventually will.

As the days pass, the world becomes increasingly unnatural, and if you're curious enough to uncover every secret, you may discover the truth behind humanity's disappearance—and why it feels like something has been watching you since the moment you spawned.

You're not alone.

You never were.
