Backrooms 🚪

📖 Description
Dare to step through a door that should never have been opened…
Brings the unsettling world of the Backrooms to Minecraft. The Backrooms are an endless maze of liminal spaces—places that feel strangely familiar yet deeply unsettling. Empty hallways, abandoned rooms, and silent corridors create an atmosphere of isolation where something always seems to be watching.
As you explore, you'll encounter mysterious and hostile creatures lurking in the darkness. They will stop at nothing to hunt you down, turning every step into a fight for survival.
The only way to enter or leave the Backrooms is through lonely doors scattered throughout the world. Some will lead you into this endless nightmare, while others may be your only chance to escape… if you can find them before it's too late.
While exploring the Backrooms, you may come across loot chests containing the same treasures found in some of Minecraft's structures, such as Ancient Cities, Mineshafts, End Cities, and more. If you're incredibly lucky, you might even discover an extremely rare chest containing the exclusive Suffocate enchantment.
Suffocate is an exclusive enchantment for Axes and the Mace. Striking a mob with a weapon enchanted with Suffocate forces it into the ground, causing it to suffocate until it escapes or dies.
At the moment, the mod only includes Level 0, the iconic endless yellow maze. However, this is just the beginning. Future updates will introduce new Backrooms levels, each with their own unique atmosphere, new creatures to survive against, and perhaps even even more valuable loot hidden throughout the endless halls.
Will you step through the door?
