Fallout Tactics: BoS → Junction City
This all seems like bravado, but nevertheless, it is necessary to recover the remains of this "potential enemy" so that Brotherhood technicians can identify its weak points. Apparently, we are facing a major war with the mechanical soldiers, and we need to gather as much information as possible about them.
The townspeople likely scattered the robot's remains to their hovels, and you'll need to thoroughly search the town without getting into any conflicts. The mayor might be able to help, as Junction City is having trouble with a gang of Reavers who have appeared in the area, also interested in rumors of a broken robot. Another task is to notify the town mechanic that a position has opened up for her in the Brotherhood.
The mayor will offer to give you one of the broken robot's parts if you deal with the Reavers. The mayor's assistant, a lady in red standing in the next room, will tell you where to look for the missing parts. But since you're already in the south, it's best to head southwest to a lonely shack. Near the shack, you'll have a small fight with a group of Reavers.
The bandits weren't particularly kind to the lucky owner of one of the parts, simply killing him. They hauled the sought-after piece of hardware to their temporary camp in the northeast of the map. I'll have to pay him a visit. It must be said that after the super mutants, the Reavers are easy to take out.
Now, without delay, head to the mayor's residence. If you start wandering around the city and taking in the local sights, a group of Reavers will "book" an appointment with the mayor, and the mayor himself might not survive. It's best not to wait for the bandits to start shooting at the townspeople, but to preemptively clear out the entire gang. Exit through the northern gate and slowly move east toward the mansion where the reavers have built their nest.
A commander in red armor with a machine gun is hiding behind the door, but he can be pretty well damaged through the cracks in the wall. On the workbench nearby is one of the robot parts. Be careful in the barn: there's a machine gunner lurking behind the logs.
Not far from the south gate, some homeless guy named Chuck will try to sell you something like a vibrator, masquerading as another robot part. Bring this thing to the Brotherhood, and the whole bunker will laugh at you. Also there, by the south gate, a little further west, in a small house, you'll find Casey, the local mechanic. She'd love to move into the Brotherhood bunker, but she can't leave the wounded man lying on the table. All you need to do is heal the poor guy, and when you return to base, you'll find Casey already there.
There's another interesting spot in this location. In the northwest corner of the map, look for a staircase leading to the catacombs, home to several giant, boar-like rats and a ton of loot, including the game's most useless machine gun. Moreover, after completing this mission, you'll be able to purchase your first set of energy armor. Next, we'll be heading to Coldwater.
