Cave Horror

Random terrors stalk you in the dark caves of Minecraft.

What is this?

Cave Horror is a 100% vanilla datapack for Minecraft: Java Edition 26.3. No mods. No resource pack. Just drop it in and the caves will never feel safe again.

While you mine deep underground (Y ≤ 40) in darkness, every ~5 seconds there is a 35% chance that one of five random horror events strikes — then a 2-minute cooldown before the dark can touch you again.

The 5 terrors

• 👻 Whispers — disembodied voices circle you in the dark. "did you hear that?"
• 🌑 Darkness — total blackness for 5 seconds with a warden's heartbeat pounding in your ears.
• 💀 THE WATCHER — a floating wither-skull figure in pitch-black armor. It only moves when nobody is looking at it — every 2 seconds it teleports 4 blocks closer. Look away too long and it jumpscares you.
• 🪨 Rumble — the cave itself groans as gravel dust rains from the ceiling.
• 👣 Stalker — footsteps approach, louder and louder... then silence... then a final whisper right behind you.

Features

• ✅ 100% vanilla — works on any server, no client mods needed
