The Lucky 38 is a hotel and casino on the New Vegas Strip in 2281. It is occupied only by Mr. House, the ruler of New Vegas, and his securitrons.
The most prominent element of the New Vegas skyline, the Lucky 38 is a pre-War relic and an enduring monument to Mr. House’s vision of Las Vegas: luxury without decadence, refinement without elitism, class without snobbery. But to assume that it was just a casino is erroneous, as in the years leading up to the war, Robert House thoroughly modified the building in preparation for the upcoming nuclear war.
