About this project

What does The Lost Levels add?

The Lost Levels

The Lost Levels is a Backrooms-inspired horror and exploration mod that adds several liminal dimensions to Minecraft.

Instead of entering through a portal, you can accidentally noclip out of reality by flying into a wall, falling in the wrong place, or running into a wall. Once you enter, you will need to explore each level and find a way out.

Current Levels

The Yellow Halls

A huge maze of yellow rooms and hallways filled with buzzing lights. The area is confusing, repetitive, and easy to get lost in.

The Poolrooms

A large network of tiled rooms, flooded hallways, and indoor pools. Some areas are calm and open, while others are dark, cramped, and much deeper than they look.

The Neighborhood

A quiet neighborhood with repeating streets and houses. The roads can loop back around, something may be watching you from inside the houses, and making the wrong choice can reset your escape progress.

Features

  • Multiple Backrooms-inspired dimensions

  • Procedurally generated levels

  • Noclip-style ways to enter

  • Hidden exits between levels

  • Creatures and other dangers

  • Unique escape mechanics

  • Custom sounds and atmosphere

  • More levels planned for future updates

No normal portals are leading into the Lost Levels. You might enter while exploring, flying, falling, or simply running into the wrong wall.

Once you are inside, finding the exit is up to you.
