Gun Run is a quest in Fallout 4.
Your arrival at the town of Salem spooked the mirelurks. It's up to you to take them out and restore the peace.
- Go to Rook Family House and kill three mirelurks nearby. Barney will invite you to his bunker.
- Talk to him and accept the task to reactive the five turrets:
- Two terminals are located on the opposite corners of the restaurant, just behind the church.
- Another is in the church steeple.
- The fourth is on the upper floor of the Rook Military Surplus store, near Barney's home.
- The last is in the alley opposite the church.
- Return to Barney for a key and Reba II.
