Jacobstown sits at the same general location as the pre-war settlement of Mount Charleston, a small alpine community high in the mountains west of the Las Vegas Valley. Post-war, the area was of little interest to travelers and scavengers due to its remote location and lack of salvageable material. It was not until the past twenty years that it became a permanent settlement for any group. 雅各布斯鎮的名字來源於雅各布：一名鋼鐵兄弟會的聖騎士，和馬庫斯結伴一同發現了破碎嶺。馬庫斯為紀念這位老朋友，用他的名字命名了此地。後來成為當地警長的馬庫斯 took it upon himself to find a refuge for the 「broken-minded」 of his kind— low-intelligence super mutants and schizophrenic nightkin. It proved to be more difficult than holding on to Broken Hills, but he eventually discovered Mount Charleston and decided it was a good spot to set up a community.
Unfortunately for Marcus, not all of the nightkin were content to live under his rules. Davison (who currently talks to a brahmin Skull named Antler in the bowels of the REPCONN test site) and Tabitha (who broadcasts her particular brand of insanity from Black Mountain) broke off on their own, eventually winding up with their own dysfunctional super mutant communities. Though Marcus is disappointed at how things turned out, he does the best he can to take care of Lily and the other super mutants and nightkin at Jacobstown.
Other than the super mutants and nightkin, Jacobstown is also home to an unnamed super mutant master. He has a "normal," cultured voice (similar to Neil's), instead of the more gravelly voice used by the other super mutants, but says the same generic dialogue phrases.
Although the Nightkin will warn you not to stare at them, doing this will not turn them hostile.
In an upstairs room of the lodge, there is the one and only pinball machine in the game.
The mutants appear to still have an interest in heavy weaponry and destruction; when spoken to, the normal mutants will comment about wanting miniguns or missile launchers from Marcus.
At higher levels, cazadores will often spawn near the front gate to Jacobstown, and may attack the super mutants.
