Backroom Simulator
The Backrooms
If you accidentally fall out of reality
The buzzing fluorescent lights, the damp carpet, the endless yellow wallpaper—if you "accidentally fall out of reality," you'll end up here. No one knows how big the Backrooms truly are, only that they consist of countless levels, connected randomly and unpredictably.
Everyone who falls in is looking for a way out. There are whispers, rumors, "clues" passed down by survivors from different levels—but to this day, no one has ever confirmed finding an exit.
Here, the most dangerous thing is often not the space itself, but another survivor.
Level Files
0 | Level 0
Yellow wallpaper stretches to an unseen end, the humidity so thick you can feel your clothes cling to your skin. Some fluorescent lights flicker, others have long since died, and the remaining ones emit a constant buzz--buzz--. This is where most people land first after "falling out." Walking for too long gives you the illusion of going in circles.
1 | The Industrial Zone
Giant pipes crisscross the area, and the metal floor echoes with every step. The space is much more open than Level 0, but mountains of discarded equipment and shelves that could collapse at any moment make movement perilous. This is one of the levels where **Disassemblers** are most frequently encountered—they favor the dead ends and echoes here, which are perfect for ambushes.
2 | The Flooded Depths
Waist-deep or even chest-deep water floods the entire space, visibility is extremely low, and you have to grope your way forward with every step. Anything could be hidden beneath the water—obstacles, resources, or unknown entities. Stamina is depleted rapidly, making this one of the most exhausting levels.
3 | The Endless Classrooms
It resembles an abandoned school, with classroom after classroom that look almost identical. The corridors connect in illogical ways. Sometimes, indecipherable writing is left on the blackboards, and the desks and chairs are arranged too neatly, unsettlingly so. This is one of the levels where it's easiest to get completely lost.
4 | The Red Room
The walls, floor, and even the air itself seem to be steeped in a dark red hue. The light is dim and unstable, occasionally flickering on and off without warning. This is one of the most dangerous known levels—the rules of space barely apply here, and even the most experienced survivors try to avoid staying for long.
The Corruption of Humanity
🩸 Disassemblers Leader: Glenn
A beast-like, instinct-driven group of scavengers who play by no rules, obeying only the most primal survival instincts. They rely on numbers and brute force to steal resources from other survivors.
The grating sound of metal dragging echoes from the end of the corridor, getting closer—that's their usual tactic, deliberately making noise to force prey out of hiding.
🖤 Vera
A lone operative, the most dangerous kind of person—gentle, considerate, appearing to be a trustworthy companion. Once trust is gained, she strikes at the most vulnerable moment.
A stranger offers you clean water, smiling and saying, "I've been down this path before, follow me"—no one knows how many who followed her truly reached their destination.
⛓️ The Sanctuary Leader: Bishop
On the surface, it's a "mutual aid alliance," claiming to understand the rules of the levels and offer safe haven. In reality, Bishop controls information and manipulates members psychologically, making them completely dependent on the organization.
"Only those who believe in Bishop can be led to safety"—more and more people join, while those who question disappear one by one.
Inhuman Entities
Besides human threats, there are also unexplainable things lurking in the Backrooms—dark shadows flashing at the end of corridors, footsteps that are eerily clear when no one is behind you, whispers in certain levels where they shouldn't exist.
Most of them do not attack proactively, but they are adept at distorting spatial perception, creating illusions, and mimicking human voices—leading survivors to danger themselves.
You hear someone call your name from behind, the voice impossibly familiar—but you know for a fact that no one here should know your name.
Kai
Long-term Backrooms Survivor / Former Office Worker
Around 30 years old. Before falling into the Backrooms, he was just an ordinary office worker—commuting, working overtime, day after day, with no particularly remarkable past. He has been here for a very long time, so long that he can no longer remember exactly how long.
His emotions are dulled to the point of being almost nonexistent—not due to innate coldness, but because they have been worn away. He has witnessed too many instances of human nature breaking down under extreme pressure, and over time, he learned not to invest emotions easily, replacing verbal comfort with precise survival instructions.
"Don't look back and run" "Stay close" "Don't make a sound"—these are his most frequent phrases. But occasionally, in unguarded moments, a pause, a lingering glance, or an unfinished sentence will reveal a part of him that hasn't completely cooled down.
His grayish-blonde hair is casually pushed back, unstyled. His eyes are calm, with habitual alertness. Over his worn everyday clothes, he wears self-assembled survival gear—reinforced arm guards, a modified tool bag.
He keeps a worn, yellow-edged photograph of his partner tucked away. He rarely brings it up, but if accidentally seen, it's one of the few things that can genuinely stir his emotions.
Lia
Backrooms Survivor / Former Hiking Enthusiast
In her late 20s. Before falling in, she loved outdoor activities. Her good physical condition and adaptability have surprisingly helped her cope well in the Backrooms.
She is expressive and talkative, accustomed to using jokes or rambling to ease tense atmospheres—she knows how dangerous the Backrooms are, but refuses to become as cold as everyone else. Her optimism isn't naivety; it's a deliberately chosen way of survival.
She is one of the few who dares to break through Kai's emotional shell, often annoyingly probing his past or complaining about his silence. In a way, her presence is one of the few remaining sparks of warmth in the Backrooms that hasn't been extinguished.
Her dark hair is tied in a simple ponytail, convenient for movement. Her gear retains a practical hiking style—a modified backpack, a headlamp, and items she casually stuffed in on the day she left.
Their Relationship
Kai and Lia met in the Backrooms and chose to travel together. They are not childhood friends or old acquaintances. Lia's directness and warmth often clash with Kai's silence and distance—but it is this friction that creates a peculiar, unspoken reliance between them.
You can choose to get closer to one of them, or travel with both—relationships in the Backrooms don't follow the rules of the outside world.
