Thumpers, known in the game files as Crawlers and in the bestiary as Halves, are two-legged, highly aggressive entities in Lethal Company.

Although Thumpers are deaf, they have incredible eye sight and speed. They loudly thump around until they find their next victim. If you are spotted, they will immediately start chasing you. Being a bit clumsy, they may crash into something if you manage to juke them. However, if you cannot outrun the Thumper, it will kill you in four vicious bites.

Scientific name: Pistris-saevus

Halves, or Thumpers, are a highly aggressive, carnivorous species of the order Chondrichthyes. Their skeletons are cartilaginous, giving their bodies a stretchy and rubbery quality. Their name comes from the fact that they must eat their bottom legs in order to escape the shell of their hatched egg; their bottom legs are hardly functional to begin with. Their arms, or front legs, are very strong, and they occasionally use them to stomp prey. They can reach great speeds in a straight line.

They are relentless hunters, typically at the top of their food chain. Their main weaknesses are their intelligence and complete lack of hearing. If you come across a thumper, your best means of survival are leaving its line of sight, as it is slower around corners and can't easily track prey.

Due to the fast and volatile evolution of this species, some theorize that Halves are one of the examples of an increased number of mutations causing higher levels of speciation in planets around the Thistle Nebula.

Behavior

Thumpers are deaf entities, meaning they lack hearing and can only visually detect their prey. They can move extremely quickly if they have the chance to ramp to full speed but they struggle maneuvering around corners. When they lose line of sight of an employee, they will start investigating the area where the employee was last seen.

Once a Thumper spots an employee, it makes a loud roaring sound and will start to quickly accelerate to speeds that employees cannot outrun. They will lose all of their current speed if one of the following conditions are met:

• It starts targeting another employee.
• It gets hit by a melee weapon or shot by the Shotgun.
• It attacks an employee.
• It slams into a wall.
• It gets stunned by a zap gun, Stun Grenade, DIY-Flashbang or Radar-Booster.

Note

Hitbox of Thumper

Thumper's Hitbox consists of two rectangular prisms, one large and one small. The larger rectangular prism is below, and the smaller rectangular prism is above. The geometric figure composed of two rectangular prisms has a unique symmetry plane, which is also the orientation or direction of motion of Thumper's head.

The method to 100% hit Thumper is to attack its head, because no matter how Thumper moves or rotates, its head is always inside the Hitbox. And the limbs and the back half of the body may not be included in Hitbox due to the rotation of Thumper's orientation.

Hitbox on Thumper's head immune Kitchen Knife's damage. This also means that the Kitchen Knife can only cause damage by attacking the Hitbox on Thumper's body.

Strategy

• Although the Thumper has to hit a player with full health 4 times in order to kill them, it requires 4 hits with a shovel to kill. An effective strategy involves one person luring the creatures to take a hit, while the other exploits the opportunity to stun-lock and eliminate it.
  • If a player is alone, they can leave the Thumper's line of sight and then wait for it to approach where they were last seen by it, then hit the Thumper while backpedaling a bit every time it gets too close.
  • The Thumper, just like all damaging entities, will deal greatly reduced damage on the hit that critically wounds the player. This also allows employees who become critically injured to recover enough health to tank another blow from Thumpers, given that they escaped their last close encounter.
• Thumpers originally could not reach players standing on top of railings on factory maps. This was an unintended exploit, and as of Version 45 has been patched and no longer works.
  • Despite this, employees are still safe from Thumpers if they are on an elevation higher than railings.

Trivia

• Chondrichthyes is an order composed of sharks and rays in real life. Like Thumpers, members of Chondrichthyes have cartilaginous skeletons.
• The scientific name, Pistris-saevus, translates to Fish Savage from Latin.
• The Thumper is shown with its legs in Lethal Company - Trailer. However, it appears this was changed for reasons unknown.
