Enemies and monsters vary in their amount of hp, damage, armour and accuracy.
Loot from enemies is not random, but based on their weapons and equipment.
Carcasses of animals and mutants can be butchered. People and mushroomers (zombie analogue) can be searched.
Activity of certain enemies depends on the time of day.
Spiders can poison a character when attacking, and wolves can cause bleeding.
Monsters have different probabilities of detecting a character. Some react more to the visibility of the character, while others react to the amount of noise they make.
