# 🎃 Ultimate Horror Experience
Turn your Minecraft world into a nightmare. **Ultimate Horror Experience** is a horror shader pack for **Minecraft 1.21** built to make survival, horror maps, and let's plays genuinely unsettling — without tanking your FPS.
Compatible with **Iris** and **OptiFine**.
## ✨ Features
- **Pulsing chromatic aberration** — a subtle "broken camera" distortion that intensifies at the edges of the screen
- **Cold, sickly color grading** — desaturated, greenish-grey tones that drain the warmth from your world
- **Dynamic vignette** — the screen slowly closes in around you
- **Film grain** — found-footage style noise for a raw, unsettling look
- **Random light flicker** — lights fail unpredictably, just when you least expect it
- **Heartbeat pulse effect** — a red pulse that syncs with a beating heart rhythm
- **Subtle scanlines** — VHS/found-footage finishing touch
- **Extra night darkening** — nights are even more oppressive than vanilla
All effects are **fully adjustable in real time** through in-game shader options — tune the grain, vignette strength, desaturation, aberration, and toggle flicker/heartbeat on or off to match your (or your viewers') tolerance for fear.
