Fallout 3 Hints

(Optional) Test the repellent on seven more Mole Rats.

  • 1 of 4: After you finish the "Test the repellent on three Mole Rats" objective, go to the Tepid Sewers area (location 37 on the Zone 9 Map).
  • 2 of 4: Use the door there to enter the underground sewer area, then use the Tepid Sewer tour info to get through it.
  • 3 of 4: There are also raiders in the area, so you'll have to fight them, too.
  • 4 of 4: They'll kill mole rats, often before you can stop them. Still, it shouldn't be hard to find and stick-whack seven (or even ten) live mole rats in this area.
