Giant radscorpion

s are much larger versions of the Radscorpion with an even more highly effective stinger.

Giant Radscorpions
Giant radscorpions often travel and fight in pairs. It's not uncommon to see one turn from the player and back off, only to be joined by another and charge in again. In fact, they seem to operate in pairs most often, only preferring to attack alone when their partner is dead.
