The mysterious cave is a location in the Big MT in the Fallout: New Vegas add-on Old World Blues.


It is located south-southeast of Big MT north tunnel and southeast of Forbidden Zone dome entrance. It has nearly the same layout as broc flower cave, without the radioactive barrels and lit torches. It is west northwest of Elijah's Watch.

Upon entering the cave, there are paths leading to the left and right. The left branch leads to a large chamber where the legendary bloatfly lives. Going right leads to a balcony overlooking the large chamber which offers a good perch to snipe the Legendary bloatfly from. There is also a small cave offering small amount of loot, and a cot that can be slept in.

Notable lootEdit


The mysterious cave appears only in Fallout: New Vegas add-on Old World Blues.
