Sleeping monsters, however, are undetectable in this way.

This will enable humans to hide and avoid monsters. The closer/greater the number of nearby monsters, the more frequent the beeps.

While cell phones cannot be used for normal functions, they will start beeping as a monster gets close. However, if someone has wired internet, they are still fine. This makes wireless internet and telephones unusable. The monsters exert a signal-jamming presence. The easiest way to completely kill a monster is through incineration however, some monsters are smart enough and have enough pain tolerance to find a way to put out the fire before it is fatal. It is possible to kill a monster through severely mutilating and destroying its body, but a monster's innate durability and regenerative qualities make this very difficult to do. While the skull can be fractured, if any part of it is destroyed completely, it will not regenerate. They can recover from most injuries and organ damage from the neck down. Monsters also do not die as easily as humans do. However, they will continue to attack if the infected human is known to be hostile to monsters. Monsters will also stop eating humans if they see any visible signs of infection. They usually do not attack other monsters except for specific circumstances (for example, Steroid attacking Blind because Blind hurt Steroid). They will attack any non-infected human on sight. Nearly all monsters are driven by cannibalistic tendencies and are very sensitive to sound. Most monsters repeatedly utter phrases related to their desires, but they can respond to things around them, such as Steroid Monster remembering Hyun-su's weapon. For example, the Slime Monster was based off a young child's desire to not be seen. Each monster has a unique set of traits and abilities related to the desires of the human it was made from.
