Description
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:
-
Procedurally generated Backrooms levels
-
Custom mobs that stalk the dark
-
Keep a eye for your hunger
-
Built-in multiplayer support — survive (or die) together
-
Limited hidden safe zones, and secrets to uncover
-
Constant updates with new levels, entities, and challenges
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.
