The smooth, white skin that envelops this creature is an exoskeleton designed to protect the slug-like part of its main body, located in the torso. Even if part of this creature's humanoid form is destroyed, it will not have any effect on the main body.
The flexible nature of its structure allows it pass through narrow openings like ventilation ducts and other tight spaces. Its primary weakness is fire, and when it encounters intense heat, its main body will leap out of its humanoid exoskeleton to escape the heat.
The most dangerous characteristic of this B.O.W, however, is its ability to survive limb dismemberment and regenerate lost body parts after they have been destroyed. It is also capable of detaching its limbs, which are then able to search for prey independently to ensnare them. It has been proven to be nigh-invulnerable to conventional firearms; gunfire can only temporarily incapacitate it. If the player waits too long or does not leave the current area, the Rasklapanje will eventually reassemble itself and continue pursuing the player. Only extremely lethal environmental hazards are capable of killing this creature. Should the lower part of the creatures body be separated from the torso, the lower body will be capable of spraying a toxin at potential targets.
A distinctive feature of the creature is its long, leech-like proboscis that it extends from its mouth in order to feed - The creature will drive its mouth into the face of its victim, devouring it head-first. When it successfully kills its quarry, a new leech creature will burst forth from the victim's corpse, suggesting that this creature implants embryos of itself into whatever it kills, allowing itself to reproduce by hunting.
