Combat

Engineers can choose to engage in combat with creatures found in the world, in order to access resources they are nesting on and will need to defend themselves from hostile wildlife while exploring. Creatures will never attack structures built by engineers, only targeting the engineers. The engineer will die if the health drops to zero. Dead creatures drop loot on death and leave their corpses on the ground that despawn after a short amount of time if not in sight.

All creatures except for Stingers ignore engineers riding vehicles, not even targeting the vehicle.

Weapons
Below is a list of usable weapons and their damage per hit:
 * : 5
 * : 7 or 14
 * : 15
 * : 6
 * : up to 50

Creature respawn mechanism

 * There are spawn points for hostile creatures such as Hogs and Spitters, scattered around the map, particularly nearby Resource Nodes or collectibles.
 * If creatures were killed, they will attempt to respawn within 3 game days, and only if engineer is within 300 meters of the spawn point.
 * At the start of the game, (or upon game updates / balancing) the hostile creatures will be present around their spawn point by default.

To prevent hostile creature respawn, the following must be fulfilled:
 * There are at least 5 player-built buildings within the 300 meters radius of the hostile spawn point.
 * One of the building must be powered factory and is running smoothly. Note that power pole does not count as a factory, but is counted as a building. Same applies to a stopped factory due to lacking or saturation of material.
 * The existing creatures around their spawn point, if present, must be killed first.

Creature teleportation

 * If a hostile creature moves too far away from its spawn point, it will be automatically teleported back to it, provided the player is not near the spawn point (~ 80m). For example, if the engineer attempts to lure a stinger to fall off an edge, or move out of a cave, the stinger will be teleported back to its spawn point.
 * Same applies to all other creatures.
 * A creature's HP resets back to full-health when it is being teleported back to its spawn point.
