Detailed walkthroughEdit

  • Once inside the caves of the abandoned waste dump, kill the deathclaws then locate the body of Agent Grey. Listen to the Agent's holotape, Operation Summary - Blackwell. Find the Bypass holotape in one of the deathclaw nests.
  • Enter the elevator at the back of the caves and stand very close to its access panel. Play the bypass holotape in your Pip-Boy to descend into Sam Blackwell's bunker.
  • Once you get inside, you will eventually see a laser grid. You won't be able to get in until you find the note Locked out? which is nearby. Once you find the note you will have to flip the circuit breaker, turn the air flu and activate the circuit conduit which will allow you to pass the laser grid to enter an office.
  • Once inside the office, look around for a keypad. You will have to access the nearby terminal and find the entry 'Judy's Gone'. Enter this date into the keypad and you will be able to reach behind the painting on the left of you to receive items including a deathclaw gauntlet. This will unlock the quest, One of Us.
