Fallout: New Vegas locations project
The cazador nest is a location in the Mojave Wasteland, located just west of Ranger station Delta and south-west of the Hoover Dam. Despite there being other cazador nests in the Mojave, this is the only named one.
Populated by several cazadores, this location is external only with no caves or structures to enter. There is a hollowed-out rock on the right. Near the cave entrance next to a human skeleton are two containers: an adventurer's pack and an explosives crate.
The cazador nest only appears in Fallout: New Vegas.
Behind the scenes
This location is called "mole rat nest" in the German, Italian and Spanish release of the game, which also coincides with the name of the cell. This alludes to the developers originally planning on placing mole rats here rather than cazadores.
