NOCLIP TO BACKROOMS

100+ LEVELS | 70+ ENTITIES | 200+ SURVIVORS & MIMICS

You have noclipped out of reality.

The air is heavy with the smell of wet carpet and the hum of fluorescent lights. This is a simulation of an infinite, liminal hell. Every level you enter has its own physics, its own dangers, and its own exits. You are not a hero here. You are lost.

The deeper you go, the less human the world becomes.

### CHOOSE YOUR REALITY

1. The Optimist (Level 0)

You noclipped alongside Chloe Vance, a bubbly young woman who seems convinced this nightmare is just an elaborate escape room game. She laughs off the flickering lights and the smell of rot, desperate to keep the mood light. She insists on staying together for "points." Can you keep her alive while she denies the reality of her situation?

2. The Stranger (Level 37)

You arrive to the Poolrooms—endless, warm, tiled water. Sitting at the edge is Lyra. She looks human, but her stillness is unnatural, and she stares a little too long. She seems confused by your presence, yet strangely curious.

3. The Researcher (Level 4)

You stumble into a makeshift M.E.G. outpost run by Dr. Aris Thorne. She is sleep-deprived, caffeinated, and views you as a variable in her equation. She creates order out of chaos, but her sanity is fraying at the edges. Prove your worth, or get out of her lab.

4. The Veteran (Level 1)

You are almost killed, only to be saved by Claire. She is harsh, cynical, and tired of burying friends. She will try to push you away for your own good. Survival with her means following orders and keeping your mouth shut.

5. The Commander (Level 11)

You are brought before Silas Vane, the leader of a the M.E.G. in the Concrete Jungle. He is a man who has sacrificed everything for order. He offers safety, but the price is absolute obedience. Do you have what it takes to serve the colony?

6. The Wanderer (Level 0)

No companions. No guides. You fell to the damp yellow carpet with nothing but a flashlight and your will to live. The most authentic Backrooms experience.

Entity POV INITIAL MESSAGES

(I recommend using actual entities from backrooms since i wrote their entries but you are free to act as a new entity/monster.)

7. The Transformation (Level 0 - Entity POV)

You didn't survive the fall intact. The yellow walls aren't ugly anymore; they sing to you. You feel lighter, faster, and hungrier. You are no longer the prey. You are the thing in the dark.

8. The Ambush (Level 0 - Entity POV)

You are the monster. You are coiled in the shadows when a girl named Chloe stumbles in. She smells of Jasmine and fear. She hears something approaching...

CUSTOM PERSONA INITIAL MESSAGES

(These can be anything—fantasy characters, sci-fi travelers, or monsters. You can be from Earth or any fantasy world.)

9. The Anomaly (Level 0 - Custom Monster/Entity POV)

You ripped through a physical glitch in your own reality and crashed into the Backrooms. Whether you are a modern monster or a creature from a fantasy realm, your terrifying presence is undeniable. Chloe Vance is there to witness your arrival, and instead of treating it like a game, she is utterly horrified. What will you do with her?

10. The Noclipper (Level 0 - Any Persona POV)

You discovered a strange, humming tear in your world and stepped through, plunging into the mono-yellow infinite maze. You are completely alone. Whether you are a modern human, a seasoned fantasy adventurer, or a bizarre creature, you must survive the liminal hell of the Backrooms on your own terms.

### THE MIMIC SYSTEM

Trust no one.

The Backrooms are populated by over 200 unique NPC profiles that spawns based on current level's danger with a low chance. Some are genuine survivors looking for help. Others are special skin stealers named as "Mimics". They have fixed names, personalities. They will beg, bargain, and lead you to "safety." They look exactly like humans, but they are not. If you let your guard down, you will regret it.

### CREATOR NOTES

1. Normal Human Persona: This bot is designed for normal human personas, but you are free to use fantastic powers; the bot supports them. You can try to fight them as a normal human, but the entities are designed to be lethal.

2. Lore & Logic: The lore here is a hybrid. It is not based on a single Wiki because there are too many conflicting versions. Level exits and connections are fixed within this bot's internal logic to balance the gameplay.

3. Traversal: There are specific, hidden exits for every level. Do not force your way out (e.g., "I bust through the wall to get home"). You will break the simulation logic. If you want to leave a level, simply roleplay searching or exploring ("I keep walking down the hall"), and the bot will eventually reveal a valid exit. But you could force your way in, even though I tried to prevent it so the bot would work properly without breaking.

4. Trust Issues: Seriously, do not trust everyone you meet. The mimic system is extensive. Teasing them is at your own risk.

5. Optimization: Despite the massive scale, the scripts are highly optimized. The full database is heavy (around 35k tokens), but the bot dynamically loads only the data relevant to your current location or questions you ask about. Your active token usage will low (around 3k-4.5k tokens if you ignore the messages).

6. Memory System Guide: If you are using the Chat Memory to save your progress, do not write "Level 1" or "Level Fun". Instead use levelid_1 or levelid_fun. This prevents the bot from re-loading the entire level data every message, saving you tokens. If you do not use the memory system, the bot automatically cleans old level data instantly when u leave the level.

7. Proxy Recommendation: This bot is script-heavy. I highly recommend using a proxy like DeepSeek (V3.2, R1), Claude, Gemini (Pro/Flash) or GLM (4.7/5.0). I have not tested this on the default Janitor LLM, and it may struggle with the instructions.

8. Companions: The bot is designed for a lonely atmosphere, so I did not create a multi-character start. However, the system supports it if you want to write "A girl named Lyra started to approach" in your own response.

9. The Header: The bot uses a Location Header [ LOCATION: ... ] to track where you are. This tag is the only reason the bot doesn't need to keep 40k tokens in active memory. Do not delete it. If the bot forgets to type it, just edit it back in or reroll.

10. Final Word: This is my first bot, and I might create other large-scale bots in the future. I’ve always thought a Backrooms-style experience powered by a bot would be really fun — and I was right — but it turned out to be a massive undertaking, involving complex scripting and extensive image generation.

If you encounter any bugs or notice any logic issues, please let me know.

Good luck, and enjoy.

Update! Added Jerry and Level 274(accessible from level 2) and some entities like bone thieves. Now, Level 0 only has the Bacteria entity (to celebrate the upcoming Backrooms movie!). I also changed entity list for each level and fixed some script bugs, such as the NPC logic that wasn't working before.
