Overkill is a one-star (★) challenge added in the Fallout: New Vegas add-on Gun Runners' Arsenal.

Challenge requirements

The player must kill any animal with either a Fat Man or a fat mine to complete this challenge.


Grants 250 XP upon completion.


  • Kills are valid if made with either the standard and GRA version of the Fat Man, Fat mines, or Esther.
  • Killing an animal by physically hitting it with a timed mini nuke will count toward the total, even though the nuke hasn't actually exploded.
  • Mutated animals do not count, only regular animals such as ravens, coyotes, and all types of dog, including NCR, Legion, Fiend and White Legs dogs, along with Cyberdogs.
  • This challenge is not repeatable.
