Fallout: New Vegas Game Add-Ons (DLC) Hints

Where can I find the five upgrade circuit boards?

  • 1 of 4: The first one is on a destroyed eyebot that's just past the locked reactor door in the Hopeville Missile Silo. You'll find it while working on the "The Silo" quest's first objective.
  • 2 of 4: The next one is under a desk in the NW corner room in the HQ building at the Hopeville Missile Base Headquarters. You'll come across that location while doing the "The Job" quest's first objective.
  • 3 of 4: The third one is behind a locked door on the first (highest) floor of the Ashton Missile Silo, which you'll be visiting for the first objective of the "The Divide" quest.
  • 4 of 4: The others can be found in the Third Street Municipal Building and near the entrance to the Cave of the Abaddon. You'll be able to find both of them while doing the above quest's fifth objective.
