Wasteland captive

Captives are imprisoned humans captured in 2277 by super mutants, found at super mutant encampments throughout the Capital Wasteland.

Background
Captives are nothing more than normal wastelanders unfortunate enough to be captured by super mutants. However most people in the wasteland say that they do not know why super mutants choose not to kill and eat their captives, but some events suggest two main reasons.

During the quest Big Trouble in Big Town some humans from Big Town are captured by super mutants and held in the Police HQ in Germantown. Apparently these humans have been captured to be used as food. While in the Police HQ, a super mutant can be overheard conversing with a human who is about to be killed. The human asks why he is to be killed when there are plenty of human remains available (presumably from other captives). The super mutant jailer reveals that they prefer their food to be from a fresh kill.

A friendly super mutant, Uncle Leo, suggests that captives are used to create more super mutants. This is corroborated by dialog overheard from other super mutants in other parts of the Wasteland, who remark that they need more new recruits, and so they must abduct more humans to transform into super mutants (using green stuff), which would be consistent with the method of super mutant creation practiced by the Master.

Other interactions

 * Releasing captives results in a karma boost. Care should be taken that you do not accidentally kill the captive while killing their captors. If you free the captive, they will thank you and offer some food, Rad-X, or ammunition. If you accept these supplies, you will receive 50 karma points and the supplies. If you tell them to keep it, you will receive 75 karma. There is no karma penalty for leaving the captive to their fate. Most captives are killed right away after being freed as they run toward super mutants within the area.
 * If you execute the captive you will lose karma, although it seems to balance out if you release the captive and then kill them.
 * If you ignore a captive or choose to leave them to their fate, a new captive will eventually respawn along with new super mutant guards if you revisit the location. However, if you free the captive, or if the captive is killed, then no new captives will appear in that location.

Locations

 * The first captive you are likely to encounter is north of the Anchorage War Memorial, where the fifth Keller Tape is also located. The captive is in the tent behind the trucks, guarded by a level-appropriate super mutant armed with a super sledge and two centaurs. Warning: Do not shoot the trucks or you will kill the captive. Assuming you have followed the Wasteland Survival Guide quest early on, this should also be your first encounter with a super mutant. If you decide to escort the captive after freeing him, he will run to the northwest of the map, near Fort Constantine, and will keep running beyond the northern map limit, stopping at a rock formation there for the remainder of the game.
 * One is halfway between the Jefferson Memorial and Rivet City. It is difficult to walk between the two places without noticing a pocket of 3-6 super mutants. The mutant at the top holding a minigun stands next to the captive. There is also a Lying, Congressional Style (Fallout 3)|Lying, Congressional Style book laying beside some ammunition cases and gore bags. Once freed this captive runs up the Jefferson Memorial Catwalk, past Irradiated Metro, across the bridge, past the Citadel, follows the road past Alexandria arms and stops next to a bus opposite the raider camp next to the Flooded Metro. He will run back to that spot if you try to move him. Soon after he randomly disappears. - Note: You may find this area completely deserted of enemies, you can just walk in and free the captive (All platforms - Confirmed). Note that Crazy Wolfgang, Crow, Lucky Harith and Doc Hoff regularly pass through here (as it is part of their travelling route) and will be attacked by the super mutants. If you stumble upon them passing by, assist them in killing the mutants or they might get killed.
 * One at Hallowed Moors Cemetery. Watch out for traps, and about 6 super mutants. Don't forget to grab the second Keller Family Transcript while you're there.
 * A captive is at Mason Dixon Salvage surrounded by about 8 mutants.
 * Between Mason District South and Hubris Comics. There are six mutants, beware of the cars which might accidentally kill the captive.
 * Where the highway enters the eastern side of DC. It is easiest to walk from Friendship Heights to Farragut station, hugging the city walls. The captive is guarded by a mutant and centaur. If you continue west you will find a small blockade with two mutants and a centaur, and a few gore bags. A mini nuke, two first aid boxes and ammunition boxes are in this blockade.
 * There are two captives at Clifftop Shacks which is almost due north of Minefield and west of Vault 92. The super mutants see you coming and therefore come to meet you, so it's easy to dispose of them without hurting the captives. However, this area may become a battle site between raiders, the Brotherhood of Steel Outcasts and the super mutants.
 * There are two captives in the Roosevelt Academy escape tunnels and maintenance section. If you release the captives before you completely clear the area of super mutants and centaurs, they will likely be killed in their escape, but you will not suffer any karma penalty if that happens.
 * A random encounter can occur in which two super mutants are holding a captive for you to rescue.

Bugs

 * A captive may, at times, not have ropes around their wrists while still acting as if they do.
