Monsters are hostile entities and serve as the main threat to Survivors. There are 29 Monsters currently in the game. You can get information about them in the Logbook. By killing Monsters, there is a chance to unlock their information in the Logbook.
Bosses (not to be confused with Teleporter Boss) are a type of Monster with much higher health and damage output, and offers much more threat to the player than most regular Monsters.
All Monsters except for Magma Worms, Overloading Worms, Aurelionite, the Alloy Worship Unit and the Twisted Scavengers can spawn as an Elite monster.
- When some Monsters have nothing to do, they jump up and down repeatedly or go to the nearest Shrine of Combat or Shrine of Chance and dance around it. This is due to pathfinding not knowing where the player is.
