Scorpion burrow is an unmarked location in the Mojave Wasteland. It is located south of Nipton Road pit stop, in the dry lake bed. Walk past the crashed airliner, and head to the area with grass and rocks. There is a mix of radscorpions of all sizes in the vicinity.
Aside from the obvious threat of multiple giant radscorpions, a pack of night stalkers roams nearby. The two creature types normally attack each other, but if the Courier is detected, they'll attack the Courier instead. The entrance looks like the ant mound.
Inside is a long corridor that leads to a large double-room cavern containing five radscorpions and a radscorpion queen. In the beginning of the corridor, a dead wastelander can be found. In the first room, there are two other dead wastelanders and in the last room, that contains the radscorpion queen, a dead Jackal gang member and a dead prospector can be found.
This scorpion burrow appears only in Fallout: New Vegas.
