Walkthrough
This quest takes place in a cyan factory building with a random layout. The room immediately after the first room has a raider leader that can be spoken to. Regardless of which dialogue option is chosen, a fight will ensue. The raider leader always has an armor piercing minigun, and will drop it upon death. There is also a legendary junkin the room and two stimpaks. Other enemies in the building may include mole rats in groups of two to three, with the occasional mole rat brood mother, and radscorpions in groups of two to three.

This quest does not randomly drop weapons or outfits, instead, most corpses and containers will contain legendary junk, caps, and medical supplies, and rarely a Nuka-Cola Quantum. It is very likely that there can be more than a dozen legendary junk dropped on this quest, with some reports of up to 18 legendary junk.

The main boss needed to complete the quest is a glowing radscorpion accompanied by another radscorpion who will drop a pet carrier upon death. The room it is in contains 4 Nuka-Cola Quantum, 100,000 caps, and a lunchbox.
