Wastelander (Fallout 3)

The anonymous civilians of the Capital Wasteland. Usually found dead, but some seems to randomly run around the Capital Wasteland until they run into a Raider or something else that kill them. Can be Ghouls, but usually Human.

Bomb
A female Wastelander will approach you and tell you bandits have strapped explosives to her. You have the option to attempt to disarm the explosives or leave her. The skill test for this appears to be fairly high (50 or higher explosives?). If you fail to disarm the explosive, she will start beeping and run away, then explode. After she explodes, the bandits will approach. One of these bandits has a Flamer. The rest have small arms and melee weapons.

Mole rats
A male Wastelander will run past you, chased by four Mole Rats. He will thank you when you've killed the mole rats ("I thought I was a goner"), but not give you anything actually profitable.

Ghouls for Underworld
Three ghouls around a burning barrel. They were on their way to Underworld, but couldn't because of all the Super Mutants. Talking to them will give you the map marker for Underworld.

Hunters
A wastelander will be run past you, followed by hunters that you may have encountered before(the ones that sell 'strange meat' which is actually human meat) the hunters can be killed for good karma, or the wastelander for bad karma. If you chose to kill the wastelander, looting the body will cause the hunters to attack you.
