We see them have backpacks or bags but rarely do we see what’s inside. They definitely don’t have clothes since they don’t change into anything. Maybe food,water,ammo but they should have more. Or sometimes there packs are too light like they don’t have anything
I don’t think I’ve seen any hard apocalypse content in the same way there is hard science fiction. Even in most zombie content the zombies are secondary to the human antagonists.
