Hunter (Fallout 3)

Hunters are people you can randomly meet in the Capital Wasteland. Some of them are regular hunters out for a wild game like mole rats. You can buy different kinds of meat from those hunters. Yet, at a time you'll meet a darker people out there. If you meet them right in middle of "hunt", as they chase a lone wastelander, killing those hunters will give you good karma. They're initially friendly to you, but naturally if you decide to attack them to protect their "prey", they will start firing at you too. Sometimes you can meet them just wandering around - in this case you can talk to them and buy some strange meat. Considering their "hunting" habits and what they tell about taste of meat, that strange meat itself well could be human meat of unlucky wastelanders.
