Backrooms Mod

iminal Structures – Level 0 in the End (NeoForge 1.21.1)

Liminal Structures brings Level 0 of the Backrooms into Minecraft — not as a new dimension, but as a quiet corruption of The End itself.

Across the End, you’ll find 19 handcrafted, standalone Level 0 rooms, generated as isolated structures. No entities. No chase mechanics. No scripted horror.

Just fluorescent lights. Yellow wallpaper. Endless carpet.

🌫️ Concept

Level 0 appears naturally in the End as rare, structure-based anomalies. Each room is:

Randomly generated

Fully solid

Exploration-focused

Atmosphere-driven

They do not connect — every structure stands alone.

Custom blocks recreate the classic Backrooms aesthetic:

Wallpaper, ceiling tiles, fluorescent lights

Carpet (with slabs and stairs)

Vents and signage

Error blocks (visual anomalies)

Darkness & Darkness Core

Biohazard blocks and fluid (apply Wither)

Functional computer block

Items include:

Almond Water (rare consumable)

Flashlight (real light, subtle flicker)

🎮 Focus

This mod is built for:

Exploration

Liminal atmosphere

Minimalist horror

Just Level 0, where it doesn’t belong.

Liminal Structures doesn’t try to be loud.

It simply places Level 0 in the End —
and lets you stand in it.
