you can build a «bond» of sorts with them over time, which will allow them to carry more for you (such
as killed
animals, or
ammo), or be less scared of things like hostile
animals and explosions.
Not only is there a wide range of
animals to hunt, their skins are also quite useful
as they can net additional funds by being sold, or can be used to craft a number of useful items, such
as additional
ammo bags, weapon holsters, syringe kits, and more.
