Blue Knight

Appearance The twins look like normal humans, with bright red skin and glowing white eyes. Behavior When first spawned, the Twins will appear as just one of them, wandering aimlessly. When approached, a bloody squelching sound will be heard, indicating that they have split into two. They will then begin to behave almost identically to the Licelings, pursuing the player. Both creatures attack, but deal 10% damage per hit. How to survive Try not to get too close to them or be observed. If you feel you've been spotted, you need to either run away or find cover before the Twin you spotted clones itself. Their presence can be detected by loud stomping sounds, even when walking. This same sound is also produced when they are pursuing a person. A clone created by a Gemini will not survive long and will die quite quickly.

Appearance Bone snatchers are large, slow-moving creatures with yellow skin, large black "eyes" that appear to be dripping with tears, and a pair of long arms. When they spot a human, they reveal the insides of their mouths and their true eyes in a pitch-black, void-like darkness. In appearance they are somewhat similar to frogs, although they lack the same hind legs. Behavior Bone Thieves move using their front legs. When at rest, they wander aimlessly, like bacteria. They remain dormant for longer periods than other creatures, but this changes if a human remains in their line of sight for a long time. Once spotted, a Bone Thieves opens their mouth, then raises their legs and leaps at the human, dealing 40% damage on impact, before returning to their dormant state during their cooldown. They also make fake sounds to trick players into approaching them (radio chatter, targeting, whistles, etc.). How to survive Either avoid getting close to the Bone Thief, as this will provoke him to attack, or avoid his line of sight entirely. The Bone Snatcher usually attacks with a straight lunge, so it is possible to dodge its attack.

Appearance Arachnids are large, quadrupedal creatures with thin, spider-like legs. They have a small body and a skull reminiscent of a dog's. Their entire body, except for the skull, is matte black. Behavior Spider spiders lurk on the roofs of levels. If a person passes under one, it will crawl off the roof and begin pursuing them. Once it emerges from under the roof, the creature will begin patrolling the level and will not return. However, if there is no roof on which it can spawn, it will appear on the ground and roam freely. When attacking a person, it deals 25% damage per hit. How to survive If you spot a Hymenoptera spider on the level ceiling, don't walk underneath it. Instead, try to go around it. If a Hymenoptera spider appears, quickly find cover. Hymenoptera spiders are among the fastest creatures in the game, and they are very difficult to outrun. To determine if the Aranean Membrane is at roof level, use the Entity Tracker or listen closely to your heartbeat. (The heartbeat becomes more noticeable as you get closer to the Entity.) Membrane spiders have a long detection range. Use this on open levels, such as Level 24 or Level 16, to increase your distance and find a safe spot. Their footsteps sound like metallic clanking, making it easy to hear them running. Use this to your advantage, as it will help you determine if one is approaching.

Appearance Dullers are pure gray humanoids with smooth, shiny skin and no distinguishable features. They have elongated, slender limbs and are quite tall. However, they always crawl on all fours. Behavior Thulers only move when no one is looking at them. They attack with their hands, dealing 25% damage. When at least one person is looking at them, they remain motionless and cannot attack or move. People can push them or even flip them over if they have a clear line of sight. How to survive Watch him while backing away. He's not very fast, and the player can look around to stop him and keep him from getting any closer, while also keeping an eye on the road ahead. It's worth noting that when Tuller moves, it feels like someone is stomping toward you.

Appearance The Transporter is a legless entity painted matte black. Behavior It crawls across the map until it spots a person who isn't crouched, then jumps in place and pursues them until it hits them and teleports them away, or loses interest. It outruns the person. It's worth noting that while chasing, it makes running sounds. It deals 10% damage per hit, but each hit teleports the player. On some maps, it teleports them to a specific location, while on others, it simply teleports them to their previous location 30 seconds ago. How to survive To temporarily avoid a collision, you can jump and climb onto an object (such as a table or bed). One of the best ways is to go into the L-shaped corridor and then run away from it. If you get teleported, run in the opposite direction. Energy drink. Crouching is also an option you can use, as if you crouch and the animal is not yet chasing you, it will not detect you.

Appearance The virus appears as a distorted, two-dimensional face. It has large, dark eye sockets and an exaggeratedly wide-open mouth with visible teeth. The face has a static and static effect, giving it an eerie or otherworldly feel. After 60 seconds, they gradually become translucent and then disappear. Behavior When the Virus is pursuing a person, it teleports to the player's current location with an electronic beeping/ticking sound. When the Virus infects a person, the player is startled and experiences distorted vision for a few seconds, after which they return to normal. The Virus deals 25% damage per attack. It may reappear in a different location, or there may be multiple Viruses in a single level (for example, during the "Blood Moon" quest). How to survive It's impossible to completely avoid this, as it will sometimes begin chasing the player from another room, even if they're not yet in line of sight. When it's chasing you, keep moving and try to outsmart it. This can be done by moving erratically or by moving to the side after moving in a straight line. The virus will despawn 60 seconds after the player begins pursuing it, allowing you to get ahead of its respawn time. If it's actively tracking you, hiding in the elevator won't work: it will be waiting outside.

Appearance The parasitic worms look like huge reddish-brown tapeworms with large, leech-like mouths full of sharp teeth. Behavior It glides aimlessly across the map, its front half wriggling back and forth as it moves. How to survive Avoid looking at him. Looking at him will repeatedly damage you, dealing 10% of the damage per hit. Each time he attacks, text will flash on the screen, and the screen itself will turn red. Just keep running and keep your distance. Otherwise, you can simply look up slightly, and he won't attack you. You can also watch the Memory Worm, but not for too long (usually a few seconds) as there is a grace period before it starts taking damage.

Appearance Fayslings look like normal humans, except they lack facial features and have a smooth surface instead of a face. They wear decent clothing: a black shirt with a red scarf and white buttons, a black belt, and gray trousers with black shoes. Behavior Faislings roam the level until they spot a human. They then begin to pursue them until they lose sight or interest. When attacking a player, they deal 20% damage, accompanied by a growl. Their running is also audible. How to survive Due to the long attack animation and smaller attack area, it's recommended to use a combination of running to maintain distance (Facelings run at the same speed as the player) and dodging to perform sharp turns or U-turns. Due to the long attack animation, it's also possible to provoke an attack and run away to increase distance if the enemy is too close.

Appearance The Strangler has a face similar to a plague doctor's mask, except it appears to be made of bone. His eyes glow white, and his body is mostly a matte blue-black. He is hunched over, his spine visible through his skin, and two rows of spikes protrude from his back on either side. Behavior It wanders aimlessly, like bacteria (only slower), until it spots a human. Once it does, it runs after the player like Naruto, hissing twice as loudly when it attacks. It deals 20% damage per hit. How to survive Climb onto elevated surfaces, like tables, find cover, or avoid his line of sight. He's very fast during a chase.

Appearance The Hound appears to be a cross between a humanoid and a canine, though it resembles a sauropod or silesaurus in appearance. It is thin and pale, with a humanoid skull, a huge mouth full of sharp teeth, long quadrupedal legs with sharp claws, and a long tail. The Hound's eyes glow white, making it easy to spot in the dark. Behavior The hounds will wander the level until they spot a human, then begin chasing them until they lose sight of them. Each hit deals 35% damage to the human. When you shine a flashlight on him, he stops briefly, turns his head to the left, and whines. He then resumes pursuing you until you shine the flashlight on him again or until he loses sight of you.

Appearance The lumps look like clay balls, with various limbs protruding from them. Mostly visible are two arms, a head, and three legs. Behavior This is a fast creature. Its unique feature is that it rolls rather than walks, as it has no legs to use as a support. It moves silently. When colliding, it roars/screams and deals 20% damage per attack. How to survive If you find him, you can usually just walk forward while he rolls toward you. In most cases, if you walk in a straight line, he won't catch you. Since it takes 5 hits to kill him, you can probably reach the elevator unless you're very far away, or jump over it if you're desperate. If you find him, just head in the other direction. You can also use a bear trap to stun him, allowing you to easily escape. You can also jump on an object, like a table, to prevent him from hitting you, but be careful, as he can still hit you when you descend.

Appearance The Skin Reaver is a tall, powerfully built humanoid, apparently made of a clay-like substance. It has one visible eye and a low-hanging jaw. Its second form, called the "duplicate", looks identical to players. Behavior Skin Snatchers will scurry around in their duplicate form when no players are nearby. Upon spotting an unfortunate victim, they will lower their head, then transform into their normal form, chase the nearest person, and attack. Each hit deals 35% damage. How to survive To survive a Skin Thief attack, stay as far away from the Duplicate as possible or simply avoid its line of sight. The best way to determine if someone is a Duplicate is by their behavior. If they wander aimlessly, they are likely a Duplicate. If the Duplicate isn't wearing the hat of the player they are impersonating, they are a Duplicate. Duplicate flashlights also have a red tint and are always on. If you're unlucky enough to have them transform into their normal form, quickly find cover. Outrunning the Skin Thief in its base form *is impossible, so it's best to hide where they can't reach you, such as in an elevator or behind cover. You can also avoid them by jumping on objects like benches or tables. It also makes a running sound when running toward a player. The running sound he makes is the same as the Faislings.

• It's impossible to escape from them without an energy drink.

Appearance The Bacteria is one of the signature creatures encountered throughout the game. It is a tall, thin creature of humanoid proportions, resembling twisted black wire. These creatures are extremely hostile and should be avoided. Behavior The bacterium wanders aimlessly until it spots the player. Upon seeing a human, it pauses for a moment to let out a loud, echoing scream that can be heard from far away. It also has the ability to stun people near it for a short time. It then begins to pursue the nearest person, howling constantly and dealing 35% damage per attack when it reaches the player. Upon each contact, it swings its arm in a slashing motion and emits a growl/scream. How to survive While dangerous, bacteria aren't very fast and can usually be outrun if the player doesn't make too many turns. Another strategy is to hide under a narrow passage, as they won't be able to reach you through it. When bacteria howl, it gives a person an advantage, allowing them to distance themselves from the entity. However, if a person is close to it, their vision blurs and they hear a ringing sound.

Humans are the most common race in the Back Rooms. Almost every human in the game wears a hazmat suit. These are yellow suits with dark green gloves and boots. They have an oxygen tank on their back and a translucent black mask on their face. These suits are essential for humans to survive the harsh conditions of the Back Rooms. In the game, humans can also be found as Lost Travelers, Wretched, and BNTG Traders. They also created groups such as the Chief Explorers Group and the Unaligned Behind-the-Scenes Trading Group.

MEG. We are the light of hope. We are M.E.G. We promise to protect everyone we can and explore unusual places no one has seen before. New discoveries are made every day. We are not perfect, but no one is. We will find a way, we will keep you safe. (This is an organization that studies the behind-the-scenes world of levels (infinite and non-infinite), which are currently believed to be infinite in number. They cover various themes, some dangerous, some peaceful. But most importantly, they contain entities that can be both safe and dangerous. Some levels have their own unique entities, which can only exist on that level, or on a limited number of levels. The various levels can be accessed via the elevator in the M.E.G. office.)

Level 28 is a large forest (with tall grass that barely reveals low-lying entities) with an old, slightly ruined stone castle in the center. However, the castle is still in fairly good condition. Nearby are the remains of ruined stone walls, which, if climbed, offer a beautiful view of the forest and meadows from above. The forest is surrounded by mountains. Dirt paths wind through the forest, some of which cross the boundary of the territory and lead into some very dark tunnels (which are dark even in daylight); they lead nowhere. Stormstone Castle is located on a hill and has a locked door. Some areas are lit by torches, but most are in darkness. The level has a blue tint, especially the sky. This makes it darker than most others and more challenging. If it starts raining, the sky will become cloudy and darker, making the challenge even more challenging. The map size is large, entities can appear

The Blue Knight is a passive creature found on level 28 in Stormstone Keep. The creature resembles a knight in azure armor with silver accents, his hands clasped behind his back. He's clearly tall and strong—a knight, after all—but no one has ever seen him without his armor, and no one has heard his voice, as he never leaves the castle, at least not while there are people on level 28. Although some say he's practically human-like, and he even seems to have a voice. Behavior The Blue Knight is reported to influence the weather through his emotions. This being is known for its sociability, but due to the loneliness it experiences, severe thunderstorms often occur on this level. Therefore, to prevent further storms, MEG sends its employees to this level to keep it company. The Blue Knight's name is Temperance.

The Blue Knight is a sentient humanoid entity that takes the form of a blue medieval knight. It resides in Stormstone Fortress on Level 28 and is encountered only there. It is known to be quite sociable, but suffers from anxiety when left alone; this sometimes results in powerful and deadly thunderstorms erupting on Level 28. To prevent such occurrences, MEG regularly sends humans to this level to communicate with it.
