# ? 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.
