Fallout 3 Game Add-Ons (DLC) Hints

Kill the Professor.

  • 1 of 3: The brain predictably betrays you, and orders its protectrons to kill you.
  • 2 of 3: You could take the time to blast each one of them for combat XP, or you could just blast the brain's tank until it shatters, which will instantly deactivate all of the robots.
  • 3 of 3: That'll finish the quest. See the Post-Quest Notes to find out how to get your final reward and leave the lab.
