|The following is based on Van Buren and has not been confirmed by canon sources.|
3-Some caravaners are characters in Van Buren.
It's very difficult to tell a 3-Some caravaner from a hired escort. All are armored and carry at least a decent firearm of some sort. At first glance, these caravaners could be mistaken for raiders. If asked, they will say because of the frequent attacks by BOS, they must be heavily armed and always ready for battle. If the player wants to trade with them, and the player is on neutral to good terms with the 3-Some Caravan, then they will be happy to trade. If the player established a hostile reputation with the 3-Some Caravan, then the escorts and caravaners will attack the player on sight.
3-Some caravaners have not appear nor were mentioned in any published game. They were to appear only in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is not certain if they will appear in any future Fallout game.
