Fallout: New Vegas locations project
Old nuclear test site
Although the site is mostly fenced off and inaccessible, the player can enter the nuclear test shack in the compound. On a nearby hill to the south is a sandbagged observation area, with chairs and five pairs of authority glasses.
The two rescued Powder Gangers from the quest Booted will travel here and come to a stop at the area just in front of the nuclear test shack, where they will most likely be killed by the many high-level feral ghouls. Even if the ghouls are cleared out beforehand, the two prisoners will simply stand around in the area until the ghouls respawn.
The old nuclear test site only appears in Fallout: New Vegas.
