About this Mod

A fully survival-friendly Backrooms experience for Minecraft.
Based on entries from the Backrooms wiki, our mod aims to recreate the many levels of the Backrooms while staying true to Minecraft’s gameplay and atmosphere.While we draw inspiration from Kane Pixel's series and other online horror media, our mod is solely based off of the Backrooms Wiki and we try our best to maintain lore accuracy. This means no cheap jumpscares no random monsters.
What To Expect
- Multiple explorable Backrooms levels based directly on wiki lore
- Fully playable in Survival Mode
- Resources and progression integrated naturally into each level
- Multiplayer-friendly exploration with friends
- Compatibility-focused design intended to work well alongside other mods
- A vanilla-style gameplay philosophy with no forced thirst, sanity, or overly complex mechanics
This mod is designed to feel like it belongs in Minecraft not add new mechanics or vastly change the experience of the game.
Current content

Note: More content is currently being worked on with level 1 comming soon
Development
This isnt just another mod hopping on the trend. Its a mod made by people who have spent many hours reading backrooms wiki pages, and consuming other online horror media. (HUGE creepcast fans btw)
At the moment, only Level 0 is available - but this is only the beginning. New levels, mechanics, entities, and features are planned for future updates as development continues.
Building a massive, lore-rich Backrooms experience takes time, and we appreciate everyone who joins us early in the journey.
Your feedback, ideas, and support help shape the future of the mod.
