Behind the scenes

⦁ Hazmat suits: Provide protection in areas with toxic air, radiation, or fungal spores. ⦁ Sturdy footwear: Perhaps the most underrated item. You'll be running a lot, and walking on damp carpets or sharp concrete in torn sneakers is a surefire way to get an infection.

⦁ Firesalt: A crystalline substance that explodes or flashes brightly when struck or thrown with force. Excellent for blinding an entity or creating a smokescreen for escape. ⦁ Crowbars and Pipes: The most reliable melee weapon. Firearms are extremely rare in Backstage, and ammo is almost impossible to find, so a heavy hunk of metal is your best friend. ⦁ Carpet Scraps and Wallpaper Paste: As strange as it may sound, experienced survivors use these to barricade passages or create temporary shelters on Level 0 or Level 1.

⦁ Flashlights and Batteries: A basic survival item. Many levels are plunged into complete darkness. Regular batteries are worth their weight in gold, as electronics in Backstage drain faster than usual. ⦁ Walkie-Talkies (Neon Walkie-Talkies): Allows you to communicate with other survivors or MEG bases over short distances. The signal is often subject to interference, but this is the only way to coordinate. ⦁ Spirit Level (Builder's Level): A simple tool that helps you understand whether your spatial perception is going crazy. If an air bubble indicates the floor is level, but you feel like you're falling, it's the mental influence of the spirit level. ⦁ Geiger Counters / Entity Detectors: Homemade or found devices that begin to crackle when approaching radiation zones or when paranormal activity (approaching entities) is detected.

⦁ Almond Water: The Backstage's main resource. It tastes like sweet water with a hint of almond or vanilla. It not only quenches thirst and hunger, but also heals wounds, and most importantly, preserves your sanity and wards off certain entities. It's available in bottles, cans, and even coolers. ⦁ Liquid Pain: Warning! It looks almost like almond water, but has a red tint. You can't drink it (it's fatal), but it can be used as a dangerous weapon against entities if splashed in their eyes. ⦁ Royal Rations: A rare but incredibly nutritious food. It looks like a tasteless jelly or porridge, but one meal is enough to completely restore your strength and keep you from craving food for days. ⦁ Super Almond Water: A stronger version of regular almond water. It's hard to find, but it instantly heals severe injuries and alleviates severe psychosis.

Level 50 - "To Leave It All Behind" / "The Grand Casino"

• *Survival Difficulty: *Class 3 (Medium Danger, Gambling Trap).

• Description: A massive, dazzlingly luxurious casino with thousands of working slot machines, roulette wheels, and poker tables. The clink of coins and music fills the space. Faceless Men act as dealers at the tables. To advance to the next level, a wanderer must play and win a certain number of chips. If they lose everything, the level "takes" them, turning them into one of the silent gamblers, forever trapped behind the machines.

Level 50: "Main Hall" / "To the Core" ⦁ The Glitches: At deeper levels like the 50th, the stability of space begins to deteriorate. Unstable entities, appearing as pixel or texture errors, inhabit these areas. They move erratically and are capable of literally erasing a person from reality or glitching their body upon physical contact.

Level 49 - "The Mined Out"

• *Survival Difficulty: *Class 4 (High Danger, Cave-Ins).

• Description: A complex system of old mining tunnels with wooden supports, rails, and minecarts. There is no lighting at all, and the air contains dangerously low levels of oxygen. The main threat is the mine's dilapidated state; a loud noise or a careless step can trigger a massive cave-in, trapping a traveler alive. Acid Slimes and Skincrads are the creatures that inhabit this area.

Level 48 — "The Sunset Hotel"

• *Survival Difficulty: *Class 2 (Low Danger, Mental Traps).

• Description: An old roadside motel, where an eternal, crimson sunset freezes outside the windows. The rooms are cozy, with lights on, beds, and clean water. However, the level is dangerous due to its "sleeping" effect. As soon as the traveler lies down on the bed, they fall into a deep, dreamless sleep. It is impossible to wake up on their own—the level slowly drains the sleeper's life force until they completely turn to dust.

Level 47 - "The Ouroboros"

• *Survival Difficulty: *Class 5 (Deadly Danger).

• Description: Dark, damp catacombs, the walls of which are made of gray stone and intertwined with tree roots. The level gets its name from its structure: it is a closed spatial loop. Going straight always returns you to the point where you started. The level is teeming with Backstage Spiders and the "Ouroboros" entity—giant worms that move through the walls and devour all living things.

Level 47: Snake Forest ⦁ Arbor Watchers: Entities whose bodies resemble charred tree trunks with long, clawed branches. They stand motionless amidst the otherwise ordinary forest, but if you get too close, the "tree" comes to life and seizes its prey.

Level 46 - "The Desert"

• *Survival Difficulty: *Class 4 (High Climate Danger).

• Description: Endless sand dunes under a scorching, relentless sun that never sets. Temperatures here exceed 50°C . A wanderer's main enemies here are extreme dehydration and heatstroke. Almond water evaporates from bottles if left unprotected. Sand Snakes and Hounds hide in the sand. Occasionally, mirages of safe levels can be encountered, luring people deeper into the desert.

Level 45 — "The Indie Archive"

• *Survival Difficulty: *Class 1 (Safe).

• Description: An endless library or archive filled with shelves of videotapes, CDs, old magazines, and blueprints. It's extremely quiet and smells of old paper and plastic. This is a unique place: the tapes and documents contain real information about the Backstage, its levels, entities, and even people who have disappeared from the real world. There are no entities here; the level is strictly guarded by researchers.

Level 44 - "Corroded Retail"

• *Survival Difficulty: *Class 3 (Unsafe, Corrosive Environment).

• Description: An abandoned retail store or clothing warehouse that has become heavily corroded. Every hanger is rusted, the clothes have turned to dust, and plaster is falling from the ceiling. The air is thick with construction dust, making breathing difficult. This is home to Windows and "Ragmen"—entities that disguise themselves as piles of old clothes and attack if you get too close.

Level 43 - "Water World"

• *Survival Difficulty: *Class 3 (Unsafe, High Risk of Injury).

• Description: A massive indoor water park, comprised of a maze of hundreds of giant plastic water slides, wave pools, and bridges. The level is noisy due to the roar of the water. Navigation is restricted to swimming or sliding. Dangers include pipes that can narrow sharply (risk of getting stuck and drowning), as well as Skin Thieves, who lurk as travelers exit the enclosed slides.

Level 42 — "The Horizon"

• *Survival Difficulty: *Class 4 (High Danger Due to Physical Conditions).

• Description: An endless beach of dark sand overlooks a vast ocean beneath a blood-red sky. Gravity here is significantly higher than Earth's, making movement incredibly difficult, and every step a struggle. The ocean water is acidic. Colossal entities (Titans) occasionally emerge from the fog on the horizon; they are oblivious to humans but can crush them accidentally.

Level 40 — "The Roller Rink's Pizzeria"

• *Survival Difficulty: *Class 2 (Moderate Danger, Food Traps).

• Description: *An endless 1980s-style pizza restaurant with arcade machines, checkered tablecloths, and plastic sofas. Fresh, hot pizza can often be found on the tables.

• Warning: Eating this pizza is fatal; it consists of an unknown organic substance and is highly addictive, turning a person into a "Sluggish" (entity). The level is inhabited by animatronics and Faceless Ones working as "staff."

Level 40: "Pizzeria" ⦁ The Animatronics: Mechanical beasts that serve as mascots for an abandoned children's cafe. They remain motionless during the day, but if you linger on the level past the designated "closing time," the robots will begin hunting, attempting to shove you inside their mechanisms.

Level 39 - "Enchanted Backyard"

• *Survival Difficulty: *Class 1 (Safe, an ideal shelter).

• Description: An endless, well-kept garden with neat hedges, beds of vibrant flowers, fountains, and stone paths. A gentle sun always shines in the sky. The fountains flow with the purest almond water, and edible fruits grow on the trees. There are no hostile entities here, only the occasional singing bird (which is an anomaly in itself). Wanderers use this level for long-term rest and healing.

Level 38 - "The Inverted Level"

• *Survival Difficulty: *Class 2 (Low Danger, Spatial Anomaly).

• Description: This level appears to be an exact replica of Level 0, but with one fundamental difference: all colors are inverted (the walls are blue, the carpet is orange), and the laws of physics are mirrored. Sounds are played backwards, and to take a step forward, you must mentally command yourself to move backward. This is highly disorienting, but the level is used by explorers as a relatively safe corridor to other floors.

Level 37 — "Sublimity" / "The Poolrooms"

• *Survival Difficulty: *Class 1 (Safe according to Wikidot) / Variable Class (Due to mental influence).

• Description: One of the most aesthetically pleasing and well-known levels. An endless complex of rooms and corridors, lined with white tiles and completely or partially flooded with clear, warm, turquoise water. There are no doors or windows, and light comes from hidden sources. The level evokes a feeling of deep peace and nostalgia. There are practically no entities here, but if you stay here too long, the water will slowly dissolve your skin, and the wanderer risks becoming trapped here forever due to an unwillingness to leave.

Level 36 — "The Airport"

• *Survival Difficulty: *Class 1 (Safe, Habitable).

• Description: An endless modern airport terminal with waiting rooms, duty-free shops, and baggage claim areas. Windows reveal runways shrouded in white fog, devoid of any aircraft. This is a major Backstage transit zone, with plenty of Almond Water and food available in the cafe. Entities do not enter here, as the level is controlled by large survivor factions that have established outposts here.

Level 35 — "An Empty Hangar"

• *Survival Difficulty: *Class 1-2 (Minimal Danger).

• Description: A colossal aircraft hangar or exhibition pavilion. The walls and floor are made of smooth gray concrete, and the ceiling is so high that it is obscured by the gloom. Absolute silence reigns throughout the level. Occasionally, you can encounter the remains of old airplanes or empty cargo containers. There are almost no entities here, but the level weighs heavily on the psyche with its emptiness and gigantic scale—it's easy to lose your sense of direction.

Level 34 - "The Sewers"

• *Survival Difficulty: *Class 4 (High Hazard, Toxic Environment).

• Description: An endless network of narrow, flooded sewer tunnels. The water here is black, fetid, and extremely toxic—the slightest contact with a wound causes blood poisoning. The level is plunged into darkness, and the echoing sounds of dripping water and splashing echo. A huge number of Corpse Eaters and Water Hounds inhabit this area. The wanderer's main task is to avoid suffocation from the toxic gases and find the stairs leading up.

Level 34: Sewers ⦁ Sewer Serpents: Long, slime-covered carnivorous worms that inhabit dirty water. They are blind, but they navigate perfectly by splashes and vibrations, pulling unwary survivors to the bottom of pipes.

Level 33 - "The Infinitely Degrading Mall"

• *Survival Difficulty: *Variable Class (Class 1 to Class 5).

• Description: A gigantic mall that rapidly "decays" as one moves deeper. While at first the traveler sees clean stores with clothing, working escalators, and useful items, after a few kilometers the walls become peeling, the merchandise rots, and the light begins to dim. In the deepest zones, the level devolves into piles of rusty metal and concrete, teeming with dangerous entities.

Level 33: "Infinite Mall" ⦁ Mannequins: Ordinary plastic mannequins in store windows. As soon as you turn away, they shift positions or silently approach. If the lights go out completely, they attack en masse.

Level 32 — "The Forest of the Queen"

• *Survival Difficulty: *Class 3 (Unsafe, Medium Threat).

• Description: A vast, endless coniferous or mixed forest, where deep twilight always reigns. The air smells of pine needles and damp earth. Paved paths run through the forest—it is highly recommended not to stray from them, as aggressive entities (Hounds and so-called "Skeletons") inhabit the thicket. Wooden huts with supplies can be found throughout the level, but some of them are Skinthief traps.

Level 31 - "Roller Rink"

• *Survival Difficulty: *Class 2 (Low Danger, Moderate Entity Population).

• Description: An endless roller rink or indoor skate park from the 1990s, with neon lighting and a smooth wooden or plastic floor. Subdued pop music from the era plays. Roller skates and skateboards can be found scattered on the floor. The level is relatively safe, but treacherous: travelers' shoes gradually begin to slip on their own, making it easy to fall and get injured. Deathmoths and Smileys lurk in the dark stands.

Level 30 — "Shift Beyond" / "The End of the Beginning"

• *Survival Difficulty: *Variable Class (Varies by Sector).

• Description: A monumental level that appears as an endless, futuristic gray void, filled with floating giant monoliths, debris from other levels, and enormous platforms. This is a unique "boundary" of the first major zone of the Backstage. Level 30 has very weak gravity, allowing wanderers to leap from platform to platform. Spatial rifts frequently occur here, allowing you to noclip (drop out) to both the safety of Level 11 and the deadly levels of the third hundred.

Level 29 — "Hyperspace" (The Screen)

• *Survival Difficulty: *Class 5 (Extremely dangerous to the mind and body).

• Description: A space composed of millions of flickering television picture tubes, monitors, and optical cables. The screens display white noise, distorted human faces, or broadcast fragments of the traveler's own memories. This level generates colossal amounts of static electricity, causing the air to literally sparkle. Being here causes severe migraines, blindness, and hallucinations. The entities here are composed of pure electricity and radio waves.

Level 28 — "The Storm Catacombs"

• *Survival Difficulty: *Class 4 (High Danger, Frequent Natural Disasters).

• Description: Vast stone catacombs or ancient fortress corridors are constantly exposed to the elements. Hurricane-force winds blow here, and freezing rain pours incessantly through cracks in the ceiling (behind which only a thunderstorm is visible). The level is partially flooded. Dangers include strong currents, the risk of hypothermia, and the collapse of old stonework. Among the entities inhabiting this level are "Hounds" and special aquatic parasites.

Level 28: "Storm" ⦁ Storm Phantoms: Floating, translucent entities woven from pure electricity and dark clouds. They circle the level's ruined bridges, unleashing powerful bolts of electricity on anything that moves.

Level 27 - "The Bunker of Springs"

• *Survival Difficulty: *Class 3 (Hard Conditions, Aggressive Environment).

• Description: An endless network of underground concrete bunkers and bomb shelters, connected by massive hermetic doors. The level is filled with rusty pipes gushing with hot springs and underground springs. The water here is undrinkable due to its high sulfur and mineral content. The air is humid and stale. The main dangers are jammed hermetic doors, which can trap a traveler in a small concrete compartment forever without food, as well as Skincrads, who ambush you in the darkness of the break rooms.

Level 26 - "Spatial Chaos"

• *Survival Difficulty: *Class 5 (Mortal Danger, Geometry Unstable).

• Description: One of the most surreal levels. The laws of physics and geometry are violated here: walls can be at 90-degree angles to the floor, gravity constantly changes direction, and corridors twist into impossible Möbius strips. The Wanderer may see their own double walking along the ceiling above them. Spatial anomalies make movement incredibly difficult here—one wrong move and you'll fall "up" or become stuck in the level's textures forever.

Level 25 — "Quarter Arcade"

• *Survival Difficulty: *Class 2 (Low Danger, Moderate Number of Entities).

• Description: An endless arcade from the 1980s. The hall is bathed in neon lights, and hundreds of speakers simultaneously blast 8-bit music, beeps, and sound effects from old video games. The machines operate without an internet connection. You can play them using quarters (coins) found on the floor. Some games offer bonuses (for example, they can materialize a bottle of Almond Water), but if you lose at certain machines, the game can "take" your soul or physically harm you.

Level 24 — "The Plastic Theme Park" (Moon)

• *Survival Difficulty: *Class 1-2 (Relatively safe, but treacherous).

• Description: Wikidot and Fandom descriptions may vary, but the classic image of the level is of an endless, indoor amusement park or exhibition dedicated to space and plastic models of planets. Everything around seems fake, made of cheap plastic. The ceiling is painted to resemble a starry night sky, and a giant model of the Moon often occupies the center of the level. It is bright and clean, entities are few, but the food and water found here are often also fake (plastic), posing the risk of starvation.

Level 23 — "The Petrying Factory"

• *Survival Difficulty: *Class 4 (High Danger, Level Environmental Threat).

• Description: A gigantic abandoned factory complex with numerous conveyor belts, smelting furnaces, and robotic manipulators. The scariest thing here is that the factory's automation still operates, but in a completely chaotic mode. Conveyors move on their own, heavy presses can suddenly descend and crush travelers, and the air is choking with smog and the smell of burnt plastic. The level is inhabited by "Mechanical Entities" and Skin Stealers, who hide among the piles of scrap metal.

Level 23: Petrified Garden ⦁ Flesh Sculptors: Creatures resembling animated stone statues. They move only when no one is looking (similar to the Weeping Angels). If they reach a human, they transform their tissue into stone while they're still alive, adding to their "garden."

Level 22 - "Abandoned Parking Garage"

• *Survival Difficulty: *Class 3 (Unsafe, Medium Entity Count).

• Description: A massive, multi-level underground parking garage. There are no cars here, but there are visible signs of accidents, concrete chips, and oil stains everywhere. A caustic liquid similar to antifreeze drips from the ceiling in places. Natural light is practically nonexistent, and the rare lamps flicker ominously. Hounds and Skinstealers frequently roam here, and every footstep echoes for miles, revealing your location to the monsters. Access to other levels is usually via elevators or exits marked "EXIT."

Level 21 - "Numbered Corridors"

• *Survival Difficulty: *Class 2 (Low Danger, Mental Hazard).

• Description: Endless, dimly lit corridors, reminiscent of basements or technical floors of large buildings. The walls are made of rough concrete, and the doors on this level are numbered in a strict but chaotic order (for example, door #402 might immediately lead to #9103). The main trap of the level is a fixation on numbers . Travelers who spend too much time here begin to suffer from obsessive-compulsive disorder, trying to calculate the logic of the numbers, which leads to complete loss of sanity. Entities are rare here, but Smiling Ones can be encountered in the darkness.

Level 20 — "The Warehouse"

• *Survival Difficulty: *Class 1-2 (Minimal Danger, Plenty of Resources).

• Description: A gigantic, seemingly endless warehouse filled with wooden pallets, cardboard boxes, and shipping containers. Almost any real-world item can be found here, from household appliances to rare tools, but most of the boxes are sealed or contain useless junk. Entities rarely wander here, making this level an important transit point for traders and Backstage explorers.

Level 19 — "The Attic"

• *Survival Difficulty: *Class 2 (Moderate Danger).

• Description: An endless, dimly lit attic of an old wooden house. The floor is littered with creaky boards, old newspapers, boxes of junk, and dusty vintage clothing. The ceiling is low, with rusty nails sticking out everywhere. The main danger here is the fragile floor (it's possible to fall into the void) and the abundance of small but nasty creatures, such as "Scabs" and "Backstage Spiders."

Level 18 - "Memories"

• *Survival Difficulty: *Class 1-2 (Depends on the wanderer's mental state).

• Description: A space that takes the form of places from a particular wanderer's deep childhood (kindergarten, schoolyard, old room). Here, you can often encounter "Plush Dinosaurs"—rare, friendly entities that help restore sanity. However, the level is tricky: if you indulge in nostalgia for too long, pleasant memories will begin to distort, turning into childhood nightmares, and entities woven from the wanderer's fears will materialize from the darkness.

Level 18: "Memories" ⦁ Plush Dinos (Memories): This child-friendly level is inhabited by animated toys. They're not aggressive, but they adapt to your deepest childhood memories. The danger is that they lull you into complacency, causing you to become trapped with them forever and die of exhaustion.

Level 17 — "Industrial Sediment" / "The Carrier"

• *Survival Difficulty: *Class 3 (Unsafe, Medium Danger).

• Description: A massive complex resembling the interior of a giant cargo ship, aircraft carrier, or refinery. The entire space is composed of rusty metal, walkways, spiral staircases, and deep tanks filled with dark, toxic, or brackish water. The air is damp and cold. Aquatic entities, as well as creatures adapted to life in rusty pipes, inhabit this area. Risks include falling into the tanks and toxic fumes.

Level 16 - "Altered Topography"

• *Survival Difficulty: *Variable Class (Class 1 to Class 5).

• Description: This level has no permanent form. It is a "fusion" of pieces from all previous levels (0 to 15), which constantly shift places, flow into each other, and rebuild in real time. You can walk through the office of Level 4, take a step, and find yourself in the middle of the ocean of Level 7 or in the darkness of Level 6. Due to constant tectonic and spatial shifts, the level is incredibly unstable and dangerous to navigate.

Level 15 - "Futuristic Hallway" / "The Quiet City"

• *Survival Difficulty: *Class 1-2 (Safe, but unstable).

• Description: Endless, perfectly clean corridors of white plastic, chrome metal, and glass, reminiscent of the interior of a futuristic spaceship. Absolute, sterile silence reigns here. Lighting comes from neon strips on the ceiling. There are virtually no entities here, but the level is dangerous due to its colossal length and the complete lack of potable water and food—you can simply die of exhaustion here, trying in vain to find a way out.

Level 14 — "Military Hospital" (The Paradise)

• *Survival Difficulty: *Class 5 (Wikidot - Mortal Danger, Hallucinations) / Class 1 (Older Fandom versions - "Paradise").

• Description: Modern canon describes this level as a massive, dilapidated, and abandoned military hospital from the Cold War. It smells of damp, medicine, and rot. The level has a powerful psychotropic effect: travelers begin to hear the voices of long-dead loved ones or doctors urging them to "go for surgery." The walls may seem alive, and the wards are inhabited by aggressive entities disguised as medical personnel.

Level 14: Paradise Naval Hospital ⦁ The Nurses: Tall, pale figures in old medical uniforms. They have no faces, and long surgical instruments instead of fingers. They try to capture wanderers to administer "treatments" that always end fatally.

Level 13 - "Infinite Apartments"

• *Survival Difficulty: *Class 2 (Low Danger, Medium Number of Entities).

• Description: An endless multi-story apartment building in Soviet or Eastern European style with narrow stairwells, elevators, and countless apartments. The windows are either boarded up or reveal only a white void. Old furniture, clothing, and canned goods can be found in the apartments. The main dangers are malfunctioning elevators (which can crush or transport you to dangerous levels) and entities such as Windows (entities disguised as ordinary windows) and Smiling Ones, hiding in the dark corners of the corridors.

Level 12 — "Matrix"

• *Survival Difficulty: *Unspecified / Special Class (Psychological Hazard).

• Description: An unusual level, consisting of a small, enclosed white room with a simple table and chair. However, its main feature is the information effect. While here, the wanderer begins to see the world as digital code or pure data. The space attempts to "absorb" the person's mind, erasing their memories and turning them into part of the Backstage itself. On Wikidot and Fandom, this level is often described as a "censorship" or "glitch," from which it is very difficult to escape before your mind is completely dissolved.

Level 12: The Matrix ⦁ The Effects: This level contains virtually no living creatures, but the space itself generates visual and auditory anomalies. They appear as floating geometric distortions or white noise. Looking at them for too long causes migraines, amnesia, and can literally "burn out" the traveler's mind.

Level 11 - "The Endless City"

• *Survival Difficulty: *Class 1 (Safe, Stable, Strict Entity Control).

• Description: A vast, modern metropolis stretching into infinity. It features skyscrapers, residential areas, parks, shops, and cafes. Enclosed spaces give way to open skies, where a light smog always hangs. Functioning utilities and resources can be found within the buildings. Level 11 is the most densely populated area in all of Backstage, home to the largest bases of the B.P.E.I. (Base Sigma) and other factions. Security actively eliminates entities that wander here (mostly rare Hounds or Faceless).

Level 11: "Endless City" ⦁ Facelings: Humanoids completely devoid of facial features. On Level 11, they play the role of ordinary townspeople. Local "adult" Facelings are completely neutral and friendly unless attacked, unlike the aggressive "child Facelings" from other levels.

Level 10 — "The Field of Wheat" / "Harvest"

• *Survival Difficulty: *Class 1 (Safe, Stable, Very Few Entities).

• Description: An endless wheat field, bathed in the soft, eternal golden light of the setting or rising sun. Dirt roads wind through the fields, dotted with abandoned tractors, barns, and windmills. A peaceful atmosphere reigns here, the air smelling of hay and rain. Barns contain supplies of Almond Water and food. Entities (such as Skinstealers) are extremely rare here and only appear at night, if the sun does set in certain areas. This is an excellent place to establish permanent settlements.

(Level 9 - "The Suburbs" / "Darkened Suburbs")

• *Survival Difficulty: *Class 5 (Unstable, Deadly).

• Description: An endless American-style suburban suburb, immersed in a perpetual, dense night. Every house here is empty, and the streets are deathly quiet, occasionally interrupted by the howling wind. Walking along the roads of Level 9 is mortally dangerous – "Manglers" and "Animators" lurk in the fog and around the corners of houses. Step off the asphalt onto the grass, and you risk "falling" into far more terrifying, unexplored levels. Some houses may be safe, but most are traps.

Level 8 — "Cave System"

• *Survival Difficulty: *Class 5 (Mortal Danger, Infested with Entities).

• Description: An endless network of narrow, damp, and dark limestone caves and grottoes. Stalactites and stalagmites hang everywhere, and the floor is littered with chasms. This level is considered one of the deadliest: it is literally teeming with the most aggressive monsters of the Backstage (Hounds, Skinstealers, Spiders). Movement is forced by crawling, in a constant lack of oxygen and under the threat of cave-ins.

Level 8: "Caves" ⦁ Camouflage Crawlers: Cave predators whose skin perfectly mimics the texture of stone and walls. They lie motionless in wait for survivors in narrow passages and attack from behind.

Level 7 - "Thalassophobia"

• *Survival Difficulty: *Class 5 (Extremely Dangerous).

• Description: A room that at first glance appears to be a continuation of Level 6, but its floor drops abruptly, descending into a gigantic ocean of icy, incredibly dense water. The level's architecture is inverted: the ceiling, complete with chandeliers, is perched atop the water at a tremendous height. Entity 20 (the Tiny Terror—a gigantic, leviathan-like creature) dwells within this ocean's depths, destroying everything in its path. Survival here is virtually impossible without a boat or a wetsuit.

Level 7: Thalassophobia ⦁ The Thing on Level 7: A one-of-a-kind giant aquatic creature that dominates the entire flooded level. It is incredibly fast, intelligent, and instantly destroys anyone who ventures far from the safety of the starting room.

Level 6 - "Lights Out"

• *Survival Difficulty: *Class 4 (According to Wikidot canon) / Class 5 (According to Fandom - Mortal Danger).

• Description: Absolute, unnatural darkness. Flashlights, matches, and any artificial light sources simply don't work here (the light is "absorbed" by the space). You can only move by touch, navigating by the cold metal walls. An ominous silence reigns throughout the level, broken only by the occasional whisper. The most terrifying thing is that you can't see the entities that dwell in the darkness, but they hear and sense you perfectly well.

Level 6: "Dive into Darkness" ⦁ Things in the Dark: Entities that dwell in the pitch-black sixth level. They are physically invisible, but they constantly stalk travelers, whispering in their ears and driving them to paranoia. They attack only when their victims completely panic.

Level 5 - "Terror Hotel"

• *Survival Difficulty: *Class 3-4 (Moderate Danger, Mental Traps).

• Description: A massive, luxurious 1920s Art Deco hotel with vintage furniture, crystal chandeliers, and carpets. The space is filled with the soft sound of jazz playing out of nowhere. The main dangers of the level are psychological influences (hallucinations, whispers) and dangerous entities such as "King Rusty" and the Death Moth. A special place is occupied by the "Hall of Machines" in the hotel basement, where the madness escalates dramatically.

Level 5: "Horrible Hotel" ⦁ Deathmoths: Giant moths that fly through the hotel's halls. Males are relatively peaceful and will not attack unless provoked. Females, however, are much larger, extremely aggressive, and capable of spitting deadly acid.

Level 4 - "Abandoned Office"

• *Survival Difficulty: *Class 1 / Safe (Best Place to Take a Break).

• Description: Completely empty, clean, and silent modern office spaces. There are windows, but beyond them lies a pitch-black void. This is one of the few levels where entities almost never appear. Working coolers with Almond Water and vending machines can be found here. Due to its safety, this level has become the primary home to large survivor bases (for example, B.P.E.I. - Base "Alpha").

Level 3 - "Electrical Station"

• *Survival Difficulty: *Level 4 (High Danger, Many Entities).

• Description: Similar to Level 2, but on a colossal scale. This is a labyrinth of cramped brick and concrete rooms filled with generators, transformers, and tangled cables. This level is extremely dangerous: there is a high concentration of dangerous monsters (Stealers, Centipedes), and there is also the risk of fatal electrocution from exposed wires. However, it is also a valuable location, as many useful tools and equipment are scattered here.

Level 3: "Power Plant" ⦁ Wretches / Insanities: These are former humans (wanderers) who have gone too long without food, water, or Almond Water, completely losing their minds due to the local atmosphere. They are emaciated, feral, and attack anyone out of sheer hunger. ⦁ Windows: Seemingly ordinary windows, revealing a pleasant landscape, enticing one to come closer. In reality, this is a disguise for the entity. As soon as one approaches, a shadowy figure bursts out of the window and pulls the victim inside.

Level 2 - "Pipe Dreams" / "Abandoned Utility Halls"

⦁ Survival Difficulty: Class 3 (Unsafe, few entities, but dangerous environment).

⦁ Description: Long, narrow, and stuffy corridors, the walls literally strewn with pipes. The air here is dry, hot, and smells of burning and machine oil. The main danger is the pipes themselves: they can reach boiling point or suddenly explode, scalding the traveler with steam. Entities are encountered more frequently here, and the constant metallic grinding and noise of machinery weighs heavily on the psyche.

Level 2: "Pipeline" ⦁ Smilers: One of the symbols of the Backstage. They live exclusively in pitch darkness, revealing only glowing eyes and a wide, toothy grin. They are attracted to light sources. If you see them, slowly retreat into the darkness and do not panic.

Level 1 - "Habitable Zone"

• *Survival Difficulty: *Class 1-2 (Minimal/Low Danger).

• Description: A massive warehouse or endless complex of industrial-style concrete corridors with pipes on the walls and low-lying fog. Unlike Level 0, useful resources can be found here, such as Almond Water (the main salvation in Backstage). On Level 1, the lights can periodically go out completely for several hours. It is during these moments of darkness that aggressive entities (Skin Thiefs, Smileys, Hounds) appear.

Level 1: "Habitat Zone" ⦁ Skin-Stealers: Humanoids capable of devouring human flesh and disguising themselves in their skin. While at rest, they appear as a shapeless mass of flesh, but in human form, they attempt to lure survivors into a trap. ⦁ Hounds: Aggressive creatures that walk on all fours and resemble humans with long, tangled hair. They attack if they sense fear, but can be temporarily subdued by looking them directly in the eye with a stern, confident gaze.

Level 0 — "Tutorial Level" / "The Lobby"

• *Survival Difficulty: *Class 1 (Safe, stable, virtually no entities).

• Description: The most famous and recognizable level of Backstage. It is an endless, chaotic jumble of empty rooms with monotonous yellow wallpaper, damp old carpeting, and deafeningly humming fluorescent lights. The space is capable of distortion: if you turn around a corner, the path back disappears. Due to the psychological pressure and linear distortion, it is easy to go crazy here, but encountering monsters (entities) here is a rare "misfortune."

Level 0: "Lobby" ⦁ Bacteria (Bacteria / Howler): A tall, unnaturally emaciated creature composed of what appears to be black wires or vines. It emits distorted human screams and stalks anyone it spots. The best way to survive is to run and never look back.
