Backrooms Eternal
by Blockadile
Backrooms Eternal adds a Backrooms-style dimension to Forge 1.20.1, with a survival layer that turns its exploration into a creative challenge.
What it does
The mod is a world generation and adventure addition built around the Backrooms, an endless space of unfamiliar rooms. Level 27 is among its named areas. Geckolib must be installed alongside it. Forge is the only loader with files, all for 1.20.1, and the latest is 1.2.0 for 1.20.1, published 2025-05-20. Client and server both need it, so players and the server run it together. The code is All rights reserved, so the mod is not open source.
Players who want a survival run in this setting can use the mod's creative approach to the Backrooms, where exploration and building share the same space. The mod was first published and last updated on 2025-05-20.
