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. Marcus, the mild-mannered super mutant sheriff of a settlement named Broken Hills, 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.
Given the snowy climate and the look of the town itself, it appears to be a ski lodge resort with certain modified or fortified parts, located in the nearby Mount Charleston area northwest of New Vegas. The entrance features a giant sign on a tower that says "Jacobstown." Left of the entrance is a pen full of bighorners. To the right there are a few bungalows. The large building to the rear is the Jacobstown lodge.
At the entrance of Jacobstown, where you meet Marcus for the first time, there are two super mutants standing guard at both sides of the entrance. Near the one on the right, there is a hollowed-out rock which has a small heart painted on it and contains minor loot.

With Jacobstown's leadership destroyed, the remaining super mutants and nightkin of the west scattered across the wasteland. Jacobstown withered away, its death going unnoticed by the rest of the Mojave.
Thanks to the Courier and Lily, a cure for the nightkin's schizophrenia was found shortly after Doctor Henry's experiment concluded. Nightkin and other super mutants in the wasteland flocked to Jacobstown, and the town became known as a haven where a mutant could find peace.
Though a cure for the nightkin's schizophrenia was eventually found, it became a case of too little, too late for Jacobstown. Disgruntled by the death of their leader, Keene, most of the nightkin scattered into the wasteland, their insanity worsening with each day. Jacobstown, constantly on guard for anti-mutant reprisals, never truly prospered.
Though a cure for the nightkin's schizophrenia was eventually found, it became a case of too little, too late for Jacobstown. Most nightkin at Jacobstown followed their leader Keene out into the wasteland, terrorizing the Mojave for years to come.

It took more time than anticipated for a cure for the nightkin's schizophrenia to be found, but in the end it was beneficial to Jacobstown. The presence of the nightkin leader, Keene, persuaded nightkin from across the wasteland to make the journey to the town. Jacobstown prospered, becoming known as a fair - if somewhat intimidating - place for a trader to do business.

With no cure for the nightkin's schizophrenia in sight, the disgruntled nightkin left Jacobstown. Without a treatment, their insanity grew. The crazed nightkin terrorized the wasteland, and Jacobstown suffered repeated reprisals from mutant-hating humans. In the end, the surviving mutants abandoned Jacobstown entirely, its existence quickly forgotten by the rest of the wasteland.
If you have visited Neil near the Black Mountain, he will reveal to you the location of Jacobstown by marking it on your map. Also, if you help Neil at Black Mountain, a super mutant master appears at Jacobstown with his voice.
When speaking to Marcus, a certain dialogue option can have him explain certain events from Fallout 1 and 2, including the Master's Army and the destruction of the Oil Rig.
Occasionally, other super mutants will state: "Sometimes I miss being in the Master's army."
In Black Mountain, there are terminal entries revealing Marcus' discovery of the place. It is later revealed in the terminal entries that there was a brief conflict with the first-generation and second-generation mutants, eventually leading to the split in leadership. This led to the discovery of Jacobstown by Marcus and the other first-generation super mutants.
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.
