Super-Duper Mart cave
The cave of rubble winds about before exiting in front of what used to be the Super-Duper Mart parking structure. A doorway on the northwest stairwell of the structure leads inside the second floor contains some derelict vehicles and feral ghouls. There is also a cooking station in front of a Master-locked security gate on this level. An elevator on top of the structure leads down into the lowest level of the flooded structure, which is now home of a deathclaw.
The Super-Duper Mart cave appears only in Fallout 4.
