It mainly consists of hookers dancing on stands, with a bar in the middle and several gamblers. An elevator to the left of the bar leads to the lower level. A door with an Average lock to the right of the bar leads to the Zoara Club. A key to the club can be obtained from Cachino, or the door has an Omerta thug near it, who can be convinced to allow entry. Troike can be found in the Zoara Club during the quest How Little We Know. Passing the stage in the Brimstone lounge are double doors leading to the courtyard.
Brimstone appears only in Fallout: New Vegas.
Behind the scenes
The name of the club (like the casino itself) is a reference to the biblical story of Sodom and Gomorrah, two cities that were destroyed by "fire and brimstone."
