lethal company monsters explained Earth Leviathan. Giant worms roaming underground. So, these things stay underground until they find prey and then burst to the ground and eat players. There are actually videos of people baiting these things or accidentally having these things eat the forest keeper whenever it's chasing them.
Before the Earth Leviathan bursts to the ground it announces it's going to attack with a large growl and then black particles start rising from the ground. As soon as you notice this is happening immediately Sprint back to where you came or just out of the attack area where the stuff is rising. If you're really heavy you might have to drop some stuff but if you're fast you can get out. They mainly come out at night. They can burrow 40 M below ground, and they can feel the slightest vibrations above the ground.
