And beneath it all, Level 0.

With Backrooms twelve liminal levels live beneath your server: wet carpet, humming lights, yellow corridors that never end.

Find the way out.

The books on the desks are the way out. Collect them. When you pick one up, something starts looking for you: only a closet can save you.

Or go in on purpose.

Light a soul soil portal: the Raid gives you 35 minutes to find a red door and get out with the loot. Discover Backrooms →

Backrooms

Twelve liminal levels under your server, each with its own generator. Some of them have things in them.

The yellow rooms go on forever, and the lights do not stay on.

Twelve levels

Each visit builds the way out somewhere new. Sounds, a bar with a direction and hints help, but never too much.

Limbo, Raid

Level 0 · The Lobby

Collect the books

Yellow rooms, humming lamps

Limbo, Raid

Level 1 · The Habitable Zone

Three levers, then the pool

Garages and gardens

Limbo, Raid

Level 2 · The Pipe Works

Three levers, then the shaft

Pipes in the dark

Pipes and copper hatches with almost no light. The Hound hunts on every level except the Lobby and Skyblock: hide in a wardrobe and wait.

Level 37 · The Poolrooms

Three levers, then the drain

Pools, a place to breathe

Level 7 · The Corrupted Chunk

Three levers, then the crack

Every block at once

How it plays

The fear director

Events come at random intervals, never on a beat you can learn. Visual scares wait until you are actually looking, and are given back if you missed them.

Things in the walls

Figures cross corridors and peek round corners, a black silhouette lunges at you, a minecart rolls by with nobody pushing it, doors close when you turn away. The Smiler waits in the dark.

The Hound

A hunter in black with red eyes. It searches by zones and remembers where you hid: wardrobes save you, but not if it saw you get in.

The Limbo

With Siege installed, dying while downed one time too many can drop you into the Backrooms with nothing, in adventure mode. Find the way out, serve the sentence, or beg your god.

The Raid

Light a portal framed in soul soil. A lobby, a countdown, up to six players a match, three matches at once. Loot, then reach one of four red doors at least 700 blocks away within 35 minutes, or lose what you found.

In game

Real screenshots from the test server, client 26.2, plugins in English.

White pillars and turquoise water in the Poolrooms

The furnished raid lobby with a purple portal and corridors

A black figure with red eyes standing in a yellow corridor

Walls of bookshelves and wooden floors in the Library

Broken floating terrain at sunset in the Far Lands

A dark corridor of bricks and copper pipes

A single tiny island with a tree and a chest in a dark void

A dim concrete parking garage in the Habitable Zone

A pool and a white hall with a structure at the far end

Works with

Backrooms works on its own. With these plugins installed they know each other, and more happens.

The Limbo (Siege): die downed one time too many and you may wake up in the Backrooms, with a level to escape.
The Raid (Siege): a soul soil portal leads to an extraction match: loot, red doors, 35 minutes. It needs Siege 1.16 or later.
Implore your god (Siege + Gods): from the Limbo, once per visit: the god sets a penance, and when it is done you are out.
