EXTRACTROOMS
by GalaxiHD
ExtractRooms, a NeoForge minigame for 1.21.1, sends players into randomly generated Backrooms levels where they must find an exit portal before a five-minute timer runs out.
What it does
Players spawn in procedurally generated Backrooms rooms filled with loot containers, and each container holds random items drawn from the full game registry, including items from other installed mods. The objective is to reach the exit portal before the timer hits zero. A Temporal Compass points toward the nearest exit room within five blocks of its search range, and some areas contain hostile creatures such as a flying predator, a patrolling mob with varied personalities and skins, and hatchlings that grow into adults within 30 seconds of hatching.
A separate Endless Backrooms world type generates a survival map without timers or squads, and it sets liminal respawn units as spawn points. Players who enter within 16 blocks of another player are grouped automatically into a squad for co-op runs. Pack developers can use a KubeJS and datapack API to define their own loot tables, filter entries by keyword and adjust progression. The mod is released under the All rights reserved license, so it is not open source. It runs on client and server, so the server and every player need it, and files are published for 1.21.1 only.
Key features
Procedural Backrooms levels
Rooms, office biomes, varied ceiling heights, shafts, lockdown doors and vents are generated as the player explores.
Registry-wide loot
Loot containers fill with random items from the entire game registry, mods included, so each run differs.
Exit timer and compass
Each run has a five-minute limit to reach the exit portal, and a Temporal Compass tracks the nearest exit room.
Adjustable tension
Heartbeat sounds, field-of-view pulses and vignette effects can be toggled to change how intense the atmosphere feels.

How it compares
The Backrooms: Found Footage is a NeoForge mod for 1.21 – 1.21.2, published under a custom license, and it is not open source. Lost in the backrooms targets 1.21.8 only and is under All rights reserved, while Backrooms: The Complex is published for 1.21.1 under the Apache License 2.0. ExtractRooms differs from all three by being a timed loot-extraction minigame with one target version, 1.21.1, and a license that reserves all rights.
