Detailed Walkthrough
A group of Mercenaries inside the NCR Storage Room are looking for Radiation Suits.

You are directed to a cave North of Nipton to find the Radiation Suits (Average Lock on the door). After you return the suits to the Mercenaries, you must raid a police station to look for NCR materials. The parts needed are: After obtaining these parts, you must travel to the Fire Station, where you encounter a Radscorpion Queen. Upon defeating her, you must travel to the heavily-irradiated upper level, where you will be told to look for more NCR Parts.
