Limen: A Backrooms-Inspired Total Conversion for Minecraft
Most Minecraft horror mods add a spooky mob, a dark dimension, or a handful of eerie blocks. Limen does something far more ambitious. It is a total conversion that replaces the core Minecraft experience with its own world generation, progression, interface, movement, and interaction systems. If you have ever wanted to step into the unsettling, endless spaces of the Backrooms, Limen for Minecraft delivers that feeling with remarkable depth.
What Makes Limen Different From Typical Mods
Limen is not designed to sit alongside your favorite modpack. It is a complete overhaul. When you load into a Limen world, you are not playing standard Minecraft with extra content bolted on. You are playing a different game built inside Minecraft. World generation, inventory limits, movement, equipment, menus, HUD elements, and even loading screens are all custom. This is why the developers recommend running Limen in a separate instance without other gameplay-changing mods.
Compatibility with mods that alter world generation, rendering, movement, inventory systems, UI, or multiplayer behavior is not guaranteed. For the intended experience, keep your instance clean.
Floor 0: Those Yellow Rooms
Floor 0 serves as the tutorial and first complete floor. It introduces players to the core loop of Limen through procedurally generated liminal environments featuring multiple room and sector types. You will encounter environmental puzzles, power systems, keys, access items, and progression equipment.
Resource management is central here. Limited inventory space forces difficult choices. Flashlights, batteries, medical supplies, and other equipment must be used wisely. The tape-based save and rewind system adds tension, while fog-of-war maps without a live player marker keep you disoriented. Custom environmental events and a fully reworked UI complete the atmosphere.
Key Features of Floor 0
- Procedurally generated liminal environments with varied room types
- Environmental puzzles and power system management
- Keys, access items, and progression equipment
- Limited inventory and resource management
- Flashlights, batteries, and medical supplies
- Custom movement and interaction systems
- Tape-based save and rewind mechanic
- Fog-of-war maps without a live player marker
Floor 1: Poolrooms Beta
Beta 1.1 introduces Floor 1, known as the Poolrooms. This expansion brings a new environment, new traversal mechanics, new progression systems, and a much larger focus on water, vertical exploration, and environmental interaction. Floor 0 remains fully playable alongside it.
Floor 1 currently includes procedurally generated Upper, Middle, and Lower sectors. You will navigate flooded rooms, pools, underwater routes, and vertical traversal paths. Custom water rendering and underwater visuals make these spaces feel genuinely alien. Environmental lighting and dark interior spaces heighten the dread.
Floor 1 Systems and Progression
- Hydraulic and pressure-based progression systems
- Pressure Rig and Survey systems
- Hydraulic systems and Phase Synchronizer System
- Hatch Bus progression
- Air management during underwater exploration
- Flooded Lower-sector traversal and catwalk areas
- New ambient audio and environmental sound
- Floor-specific UI and interaction systems
The current Floor 1 beta ends after the main progression sequence. The final encounter, final hatch sequence, and transition to Floor 2 are not yet included, but the content available already offers hours of tense exploration.
Co-op and Multiplayer in Limen
Limen includes experimental multiplayer through LAN and Steam. Co-op is still in beta and has not been tested as extensively as single-player. Desync, connection issues, latency spikes, and other multiplayer bugs may occur. All players must use the exact same Limen version. Steam integration is optional and is not required for single-player or LAN play.
If you want to download Limen and jump straight into the Backrooms with friends, the foxygame.net launcher makes it painless: it lists Limen in its add-on catalog and handles the entire installation in a single click, so you never have to manually match loader versions or move files around.
Supported Versions and Loaders
Limen is built for modern Minecraft versions and is distributed for the Fabric loader, which is required for the mod to function correctly. Before you download Limen, check that your Minecraft installation matches the supported version listed on the official project page. Because Limen is a total conversion, using the wrong loader or an incompatible Minecraft version will prevent it from running at all.
How to Install Limen for Minecraft
Installing Limen is straightforward if you follow the right steps. First, make sure you have the correct Minecraft version and the Fabric loader installed. Second, create a separate instance or profile specifically for Limen, since it should not be combined with other gameplay-changing mods. Third, place the Limen mod file into your mods folder. Finally, launch the game using the Fabric profile and start a new world.
If you prefer a simpler route, a launcher that manages versions and dependencies automatically can save you considerable time. Either way, always verify that your Limen version matches the one your friends are using if you plan to play co-op.
Final Thoughts on Limen
Limen stands out as one of the most ambitious total conversions available for Minecraft. Its commitment to replacing core systems rather than layering on top of them creates an experience that feels genuinely separate from the base game. The Poolrooms update expands the world meaningfully, and the experimental co-op opens the door to shared horror. If you are ready for something slower, stranger, and far more unsettling than standard survival, Limen is worth exploring.
