About this project
What does Jackson Horror add?

☠ JACKSON HORROR ☠
"The Darkness Knows Your Name."
Jackson Horror is a deeply atmospheric, fear-driven Minecraft horror mod that transforms your world into a living nightmare. Survive relentless hunts, unravel cryptic lore, and face Jackson — an entity that should not exist.
🌑 THE STORY
Something has broken through. On the night of the Crimson Moon, the barriers between dimensions crumbled — and Jackson walked through.
He does not attack. He hunts. He learns your patterns, tracks your movements, and waits. By the time you see those glowing white eyes in the dark... it is already too late.
Your world will never feel safe again.
👁 MEET JACKSON

Jackson is the central entity of this mod. Pitch-black, silent, and deeply unsettling:
- 🔲 Glowing White Eyes — visible from a distance in total darkness
- 😁 Sinister Grin — a wide, glitching smile that flickers when he sees you
- 👁 AI-Driven Hunting — Jackson learns and adapts to your behavior over time
- 🔊 Custom Sounds — whispers, static, and distorted breathing follow you
- ⚡ Glitch Aura — purple void particles and screen distortion appear near him
- 💀 Instant Kill — touching Jackson is fatal. There is no warning. Run.
🩸 THE CRIMSON MOON EVENT

Every few in-game days, the sky turns blood red. This is the Crimson Moon Event — and it is your greatest test of survival.
- 🌑 Blood-red sky replaces the normal night atmosphere
- 🧟 Massive zombie hordes assault your base relentlessly
- 👁 Jackson becomes enraged — faster, more aggressive, harder to escape
- 🔴 Crimson Moon Block floats ominously overhead, empowering all enemies
- 💜 Glitch Storms corrupt the terrain around you
Your only hope is a well-fortified base and plenty of resources. Even then... Jackson always finds a way in.
😈 CRIMSON STALKERS

Jackson is not alone. The Crimson Stalkers are his corrupted servants — shadowy humanoid entities with burning red eyes that work in packs to overwhelm survivors.
- 🏃 Fast and relentless — they do not stop until you are dead
- 👥 Pack behavior — they coordinate attacks and flank you
- 🌑 Darkness empowered — stronger in the dark, weaker in torchlight
- 💀 Death Particles — corrupted particles spew on death, spreading glitch corruption
👻 THE ECHO ENTITY

Deep in ancient misty forests, something else watches. The Echo Entity is a silent stalker that mimics sounds from your environment to lure you away from safety.
- 🌫️ Appears in fog — only visible at a certain distance
- 🔊 Sound mimicry — imitates chests opening, player footsteps, and animal sounds
- 💜 Purple glow — faint violet eyes barely visible in mist
- 👁 Disappears if you look directly at it — but it is still there
⚡ GLITCH DIMENSION

Using the Corrupted Portal Frame, brave players can travel to the Glitch Dimension — a fractured realm where reality itself is broken.
- 🟣 Purple lightning strikes from a corrupted sky
- 🏚️ Haunted structures filled with traps, lore books, and rare loot
- ⚡ Void corruption slowly spreads, transforming blocks into glitch matter
- 👁 Jackson resides here — this is his domain. Enter only if prepared.
- 🎁 Exclusive loot — powerful items only found in the Glitch Dimension
