Complete Entity Database

1. Bracken

Also known as: The Backrooms Monster, Neck-Snapper

The Bracken is a tall, humanoid entity with pale skin, no face, and a set of what appear to be ribs exposed on its back. It stalks players through the facility, retreating into shadows when spotted. If a player stares at it for too long, it will snap their neck in a instant-kill animation.

AttributeDetail
Danger Level9/10
Spawn LocationsAll moons, interior only
Detection MethodLine of sight within ~20 meters
SpeedWalks slowly, sprints when attacking
HP5 hits (shovel)
Can be Killed?Yes, with 5 shovel hits or 2 shotgun blasts
Sound CuesLoud breathing, rustling footsteps
First Appearancev35

Behavioral Analysis:

  • The Bracken patrols the facility interior, moving room to room.
  • When it spots a player, it will raise its arms and back away slowly while maintaining eye contact.
  • If the player maintains eye contact for approximately 3-4 seconds, the Bracken enters a rage state and instantly kills the player by snapping their neck.
  • After a kill, the Bracken drags the body to a hiding spot.
  • It retreats if you look at it and back away, but it will stalk you from adjacent rooms.

Counter-Strategy:

StepAction
1Do not run. Running triggers chase behavior.
2Look at the ground or turn away from the Bracken.
3Back away slowly while looking away.
4Close any doors between you and the Bracken.
5If it attacks, a teammate can shove it off with a shovel hit.

Kill Strategy: Brackens have 5 HP. A coordinated team can kill one: one player acts as bait (looking at the Bracken to hold its attention) while another hits it from behind with a shovel. This is risky — one mistimed hit and the bait player dies.


2. Coil-Head

Also known as: The Weeping Angel, Spring-Head

The Coil-Head is a mannequin-like entity with a spring for a neck and a human head mounted on top. It operates on a simple rule: it only moves when you are not looking at it.

AttributeDetail
Danger Level7/10
Spawn LocationsAll moons, interior only
Detection MethodProximity, line of sight
SpeedFast (when you look away)
HPInvincible (cannot be killed)
Can be Killed?No
Sound CuesMetallic clicking, spring sounds
First Appearancev35

Behavioral Analysis:

  • Coil-Heads patrol corridors and rooms at a slow walk when observed.
  • The moment no player has direct line-of-sight, the Coil-Head lunges forward rapidly.
  • It instantly kills players on contact.
  • Multiple Coil-Heads can spawn on harder moons.
  • They cannot be killed by any means.

Counter-Strategy:

SituationAction
Alone, Coil-Head approachesBack away while maintaining eye contact
Multiple playersTake turns looking at it
Need to turn a cornerBack around the corner while facing it
Coil-Head + other monsterThis is a deadly combination. Prioritize escape.

The “Coil-Head Dance”: When multiple players are present, you can “pass” the Coil-Head by alternating who looks at it. Player A looks while backing up, then Player B catches line-of-sight as Player A rounds a corner. This allows the team to navigate past Coil-Heads safely.

Critical Rule: Never look away from a Coil-Head in a dead-end room. You will die.


3. Thumper (Crawler)

Also known as: The Blind Dog, Crawler

The Thumper is a blind, quadrupedal creature with an elongated body and powerful legs. It cannot see but has excellent hearing. When it detects a player, it lets out a distinctive screech and charges.

AttributeDetail
Danger Level6/10
Spawn LocationsAll moons, interior only
Detection MethodSound-based (footsteps, voice, doors)
SpeedFast charge (faster than sprint)
HP3 hits (shovel)
Can be Killed?Yes, 3 shovel hits or 1 shotgun blast
Sound CuesLoud screech before charging, heavy footsteps
First Appearancev35

Behavioral Analysis:

  • Thumpers patrol the facility, head low to the ground, listening.
  • When they hear a player (footsteps, door opening, voice chat), they screech and charge.
  • Their charge is faster than sprint speed — you cannot outrun one in a straight line.
  • They can open doors.
  • After a failed charge, they pause briefly to reorient.

Counter-Strategy:

TechniqueHow To
WalkingWalk (shift by default) instead of running to avoid detection
Door StallingClose doors behind you — Thumpers are slowed by doors
JukingBreak line of sight around corners, then crouch and stay still
Killing3 shovel hits from behind while it is chasing a teammate
Stun GrenadeFreezes it for 5 seconds, enough to kill or escape

Pro Tip: A Thumper’s charge has a brief wind-up. If you hear the screech, immediately break line of sight around a corner or door. It will charge to your last known position, giving you time to reposition.


4. Eyeless Dog

Also known as: Blind Dog, Hellhound

The Eyeless Dog is a large, canine-like creature with a featureless face (no eyes, no apparent nose). It is completely blind but hunts with extreme sensitivity to sound.

AttributeDetail
Danger Level8/10 (outdoor), 6/10 (if careful)
Spawn LocationsOutdoor areas on all moons
Detection MethodSound only
SpeedFast sprint
HP5 hits (shovel)
Can be Killed?Yes, 5 shovel hits or 2 shotgun blasts
Sound CuesBarking, growling, heavy panting
First Appearancev40

Behavioral Analysis:

  • Eyeless Dogs wander the outdoor map sniffing and listening.
  • They cannot see anything — standing still right in front of one is safe as long as you make no sound.
  • They react to: footsteps (running especially), voice chat, doors opening, equipment sounds, and scrap dropping.
  • Once alerted, they run to the sound source and attack anyone in their path.
  • They can be distracted by sound sources (Radar Boosters, Boombox).

Counter-Strategy:

SituationAction
Near an Eyeless DogStop moving completely. Do not even turn.
Need to moveCrouch-walk. Crouching reduces footstep noise.
Dog is closeHold still and do not speak on voice chat.
Dog is chasing youRun to the ship. Jump over obstacles to break its pathing.
Multiple dogsUse a Radar Booster or Boombox to lure them away.

The “Dog Dance”: Experienced players can walk past Eyeless Dogs by crouch-walking and stopping whenever the dog turns toward them. Each dog has an aggro cone — if the dog’s head points toward you, freeze. When it looks away, move again.


5. Forest Keeper

Also known as: The Giant, Earth Leviathan

Forest Keepers are enormous humanoid giants that patrol the outdoor areas of certain moons. They have a single large eye and wear tattered clothing. They can grab and eat players in two bites.

AttributeDetail
Danger Level8/10
Spawn LocationsOutdoor, Vow and harder moons
Detection MethodLine of sight
SpeedSlow walk (deceptively fast over distance)
HP8 hits (shovel) — extremely hard to kill
Can be Killed?Yes but impractical (requires 8 shovel hits or 3 shotgun)
Sound CuesTremendously loud footsteps, deep growls
First Appearancev35

Behavioral Analysis:

  • Forest Keepers patrol outdoor areas, scanning for players.
  • When they spot a player, they walk toward them and attempt to grab them.
  • Being grabbed results in being eaten: first bite deals damage, second bite kills.
  • They can be distracted by loud noises and will investigate.
  • They cannot enter the ship but can block the doorway.

Counter-Strategy:

TechniqueHow To
Line-of-SightStay behind trees, rocks, and terrain to break LOS
Indoor EscapeGo inside the facility — Forest Keepers cannot enter
Ship DashTime your sprint to the ship between its patrol paths
Boombox LurePlace a Boombox playing music away from your path
Stun Grenade5 seconds of stun to run past

6. Jester

Also known as: Jack-in-the-Box, Music Box Monster

The Jester appears as a small jack-in-the-box toy carried by a faceless figure. It patrols in harmless mode (winding its music box), but once fully wound, it transforms into a fast, lethal killing machine.

AttributeDetail
Danger Level9/10 (wound up), 2/10 (winding)
Spawn LocationsInterior, harder moons (Offense+)
Detection MethodPatrol path (winding), line of sight (chase)
SpeedSlow (winding), Very Fast (chase)
HPInvincible
Can be Killed?No
Sound CuesMusic box melody (winding), loud roar (chase)
First Appearancev40

Behavioral Analysis - Two Phases:

PhaseDurationBehavior
Winding (Safe)30-45 secondsPatrols facility playing music. When a player is nearby, it stops and cranks its crank.
Wound Up (Deadly)Until it loses trackingChases the nearest player at high speed, instantly killing on contact. Cannot be stopped.

Counter-Strategy:

PhaseAction
Hear the musicImmediately identify where the Jester is. Warn team.
It starts crankingLEAVE THE FACILITY. Go outside.
It is chasingRun for the exit. Close doors behind you. Juke around corners.
After chaseThe Jester returns to winding mode after ~20 seconds of not finding anyone.

Critical Rule: When you hear a Jester start cranking, announce it on voice chat immediately. The whole team needs to evacuate. One player ignoring the warning equals one dead player.


7. Snare Flea

Also known as: Ceiling Monster, Head Grabber

The Snare Flea is a small, insect-like creature that clings to ceilings and drops onto players passing below. It latches onto the player’s head, slowly suffocating them while the player struggles.

AttributeDetail
Danger Level5/10
Spawn LocationsInterior, all moons
Detection MethodProximity (drops when player passes under)
SpeedStationary (on ceiling), Slow (on player)
HP1 hit (shovel)
Can be Killed?Yes, one shovel hit
Sound CuesNone while on ceiling. Muffled sounds while on player.
First Appearancev35

Behavioral Analysis:

  • Snare Fleas are stationary on ceilings until a player walks under them.
  • They drop onto the player’s head and cover their face.
  • The player’s vision is obscured and they take damage over time until dead.
  • A struggling player can shake the Flea off after several seconds, or a teammate can hit it off.
  • They are very easy to spot if you look up.

Counter-Strategy:

StepAction
PreventionLook at ceilings before entering rooms. Scan with flashlight.
If grabbedMash E to struggle. Teammate hits you with shovel to remove it.
KillingOne shovel hit on the ceiling kills it before it drops.

8. Hoarding Bug

Also known as: Loot Bug, Item Hoarder

The Hoarding Bug is a beetle-like creature that collects scrap items and brings them to its nest. It is generally passive but becomes aggressive if you take items from its territory or stare at it too long.

AttributeDetail
Danger Level4/10
Spawn LocationsInterior, all moons
Detection MethodVisual range
SpeedModerate
HP2 hits (shovel)
Can be Killed?Yes, 2 shovel hits or 1 shotgun blast
Sound CuesChittering, skittering legs
First Appearancev35

Behavioral Analysis:

  • Hoarding Bugs patrol rooms, picking up loose scrap and carrying it back to their nest.
  • They are territorial — if you enter their nest room, they raise their arms in warning.
  • If you continue approaching or stare at them, they shriek and attack.
  • Their attack deals moderate damage but is not an instant kill.
  • They steal items from the ground — if you drop something, they may take it.

Counter-Strategy:

SituationAction
Passing byDo not make eye contact, move through quickly
It is threateningBack away slowly
It attacks2 shovel hits kills it easily
It took your itemEither kill it or wait for it to drop the item (it will eventually)

Pro Tip: You can use Hoarding Bugs to your advantage. They collect scrap into neat piles at their nest. Find the nest and you may find more scrap than you expected.


9. Hygrodere

Also known as: The Blob, Slime

Hygrodere is a large, amorphous green slime that slowly oozes through the facility. It deals damage on contact and can block corridors if it spreads.

AttributeDetail
Danger Level3/10
Spawn LocationsInterior, all moons
Detection MethodProximity (it moves randomly)
SpeedVery slow
HPInvincible
Can be Killed?No
Sound CuesWet squelching, bubbling
First Appearancev35

Behavioral Analysis:

  • Hygrodere oozes through rooms and corridors at walking speed.
  • It cannot be damaged or stopped.
  • Contact deals steady damage — you have about 5-8 seconds before dying.
  • It can split into smaller blobs.
  • It follows players very slowly (it can sense heat?).

Counter-Strategy:

SituationAction
See the blobGo around. It is slow. You have plenty of time.
Blocking a pathWait for it to move, or find another route.
Cornered by itRun through it. The damage is survivable.
Split blobsSame strategy — slow and easy to avoid.

10. Spore Lizard

Also known as: The Friendly Lizard, Spore Guy

The Spore Lizard is a small, harmless lizard with glowing spots on its back. When threatened, it releases a cloud of spores that blur vision temporarily. It is completely non-lethal.

AttributeDetail
Danger Level1/10
Spawn LocationsInterior, all moons
Detection MethodRandom patrol
SpeedMedium (will run from players)
HPCannot be killed
Can be Killed?No (it is harmless, do not try)
Sound CuesSoft chirping
First Appearancev35

Behavioral Analysis:

  • Spore Lizards wander the facility, completely ignoring players.
  • If approached, they release a cloud of pink/blue spores that blur vision for 5-10 seconds.
  • After releasing spores, they scuttle away to a different area.
  • They do not deal damage, do not attack, and cannot kill.

Counter-Strategy:

SituationAction
See the lizardIgnore it. It is harmless.
It spored youWait a few seconds for vision to clear.
Worried playersTell your team it is just a Spore Lizard — no threat.

Common Mistake: New players often panic when a Spore Lizard releases spores, thinking they are being attacked. It is completely harmless. Do not waste a stun grenade on it.


11. Ghost Girl

Also known as: The Spectre, Haunting Ghost

The Ghost Girl appears as a small figure in red clothing. She haunts a single player, appearing only to them. As the haunting progresses, she appears closer and closer until she kills the player.

AttributeDetail
Danger Level8/10
Spawn LocationsInterior, harder moons (March+)
Detection MethodTarget selection (random)
SpeedVariable (teleports)
HPInvincible
Can be Killed?No
Sound CuesStatic on affected player’s walkie, footsteps
First Appearancev45

Behavioral Analysis - Four Stages:

StageVisualAction Needed
DistantSee her far away, brieflyShe has chosen a target
ApproachingAppears closer, more frequentlyWarn team, identified target
CloseRight next to the playerTarget should leave the facility
KillTouches the playerInstant death for target

Counter-Strategy:

TechniqueHow To
Identify targetOnly the affected player can see her. Ask “can anyone see a little girl?”
Evacuate targetThe haunted player should leave the facility and stay near the ship
DelayStaying near other players may delay the kill (unconfirmed)
No known cureShe cannot be stopped, only delayed

Note: The Ghost Girl is one of the least understood entities. There is no confirmed way to prevent her kill. The best strategy is to have the haunted player wait outside the facility so they do not die mid-loot-run.


12. Nutcracker

Also known as: The Shotgun Soldier, Nutcracker Guard

The Nutcracker is a large, wooden soldier that patrols mansion/laboratory interiors carrying a shotgun. It periodically stops, scans its surroundings, and fires at any player it sees.

AttributeDetail
Danger Level7/10
Spawn LocationsMansion/Lab interiors, Offense+
Detection MethodPatrol path + visual scan
SpeedModerate walk
HP4 hits (shovel)
Can be Killed?Yes, drops shotgun and shells
Sound CuesHeavy wooden footsteps, mechanical clicking
First Appearancev50

Behavioral Analysis:

  • Nutcrackers patrol hallways in a set path.
  • Periodically, they stop and do a 360-degree scan.
  • If they spot a player during a scan, they fire their shotgun.
  • The shotgun deals massive damage (2 hits kills).
  • After firing, they reload (3 seconds) before scanning again.
  • They can be killed, and doing so rewards you with a shotgun and 2-3 shells.

Counter-Strategy:

TechniqueHow To
Avoid scansHide behind walls or furniture when it starts scanning
Kill timingHit it during its reload animation
Team killOne player baits the shot, another attacks from behind
Stun grenadeStuns through all phases, easy kill setup

Nutcracker Farming: Killing Nutcrackers is one of the best ways to get shotguns, which are both a powerful weapon and valuable scrap (shotguns sell for 90-150 credits, shells for 10-30 each). For a complete database of all scrap items and value ranges, see our Scrap and Loot Guide.


13. Eyeless Dog (Pack Variant)

On harder moons (Rend, Dine, Titan), Eyeless Dogs can spawn in packs of 2-4. Pack behavior is more aggressive and coordinated.

AttributeValue
Pack Size2-4 dogs
Spawn Rate30% on Titan, 15% on Rend/Dine
BehaviorSpread out to cover more area
CounterBoombox lures work best for multiple dogs

14. Jester (Rapid-Wind Variant)

On Titan specifically, the Jester can have a shortened wind-up time, reducing the safe period from 30-45 seconds to as little as 15 seconds.

Conclusion

Knowing your monsters is the difference between a successful run and a squad wipe in Lethal Company. Each entity has a specific behavioral pattern and a counter-strategy. The most dangerous situations arise when multiple monster types appear together — a Coil-Head blocking a corridor while a Bracken stalks you from behind, or a Jester winding up while Eyeless Dogs patrol outside.

Master the monsters one at a time. Learn the Bracken dance before you tackle Titan. Practice the Coil-Head stare on Assurance. Use the terminal bestiary command to review scanned entities in-game, and always, always check the ceiling. For a full list of terminal commands, see our Terminal Commands Guide.
