The Blockrooms

No-clip out of reality. Welcome to the endless yellow halls — if you can survive them.

The Blockrooms is a fan-made survival-horror expansion for Minecraft (NeoForge) that turns your world into the Blockrooms: level after level of procedurally generated Backrooms-style rooms, tunnels and corridors, each with its own rules, threats and secrets.
