To hunt foxes, deer, or wild boars in SAELIG you need a bow and a keen eye.
If you're keen to play as a hunter you can select the Hunter start when you select your map. You will start in the wilderness with a bow, so you can start hunting straight away.
You can hold the DEL key to highlight animals in front of trees.
Animals will respawn after a day or two, however the animal you just killed will not necessarily be replaced by an animal of the same type.
AI will also hunt animals in their spare time.
Animals will attempt to flee when approached or shot at. Hitting the animal is more difficult when it is running.
