Corvega Assembly Plant

- Part of the quest “The First Step”

- Has several entrances. The whole place is huge but there's really no special loot. I would suggest exploring it as much as you can for extra ammo and weapons.

The storage area where you can use the key is located in the main floor in the middle, which you can easily get into if you entered from the Lexington side of the factory. You can get the key from the body of one of the attacking raiders in Concord (During the mission “When Freedom Calls”

The Repair Bobblehead can be found on the rooftop of the building. There are multiple exits to the rooftop. The easiest one is from the main entrance, take the catwalk to the second floor door. Once inside, you'll find the door with the red mark “Exit”. From there, you have to make your way to the large blue sphere to the south. The bobblehead is found at the end of the topmost walkway.

Getting the Jared's body and the control room may be a bit tricky. To reach it, you have to jump over the gap from the catwalk in the corner of the assembly line, next to the control room. Equip something lighter, like a pistol or just simply hide your weapon. Make sure to hold the jump button since it seems to make your jump stronger. You can refer to the video below.

After reaching the control room, you can now loot a steamer trunk containing ammo and weapons and pick up the Grognak the Barbarian comic on the table.
