Triggermen

The Triggermen are a faction in the Commonwealth in 2287.

Background
The Triggermen are a collection of organized crime syndicates who base themselves around Boston's pre-War mafia families and their traditions. This appears to be due to the influence of their ghoul members, who claim to have been members of such organizations. They will usually wear a suit or other clothing typical to the pre-War era, sometimes alongside a fedora. Most Triggermen appear to operate with a code of honor, unusual for criminals in the wastes, for example, Skinny Malone refuses to kill Nick Valentine because of the "old times" when they fought with each other in the past. They can often be seen in the company of Raiders and other such unscrupulous characters, running enterprises such as the robot racetrack at Easy City Downs.

Territory
Triggermen generally live outside society, establishing secret bases where they undertake their questionable activities. One example is Marowski's chem lab, which is hidden deep in an abandoned fishpacking plant, and is where Marowski's gang create chems to smuggle into Diamond City and other settlements. Some Triggerman gangs maintain a limited presence in larger settlements, however; Goodneighbor in particular is a haven for such groups.

Relationships
Most Triggermen are hostile towards the Sole Survivor, although some are friendly or neutral as part of random encounters or scripted events, such as Skinny Malone and his men.

A group of Triggermen can be seen in Easy City Downs with raiders, suggesting they cooperate. This is further evidenced by Sinjin's raider group which works with the Triggermen.

At the conclusion of The Big Dig, there are two Triggermen with Hancock's bodyguard Fahrenheit. This is probably why when Whitechapel Charlie asks the player to clear the warehouses in Goodneighbor which contain Triggermen, he doesn't want to tell you that Hancock is the one behind his request: Hancock is having members of a group killed, that he apparently works with from time to time.

Appearances
Triggermen only appear in Fallout 4.
