Welcome to the Backrooms... Minecraft style.

Step beyond reality and into an endless maze of yellowed corridors, buzzing lights, and the constant, uneasy feeling that you're not alone. "Backrooms: Lost in the Blocks" transforms your Minecraft world into a terrifying survival experience based on the viral Backrooms mythos.

Featuring a rich variety of custom dimensions, eerie ambient sounds, horror mechanics, and procedurally generated endless structures, this modpack traps players in a nightmare that feels alive.

Whether you choose to brave the halls alone or team up with friends (yes, built-in multiplayer is ready to go!), the only goal is simple: escape... if you can.

Key Features:

Can you stay sane long enough to find the exit... or will you become just another lost soul in the endless rooms?

Good luck. You'll need it.
