— In-game description, Fallout: New Vegas

Lady Killer is a perk for male player characters in Fallout 3 and Fallout: New Vegas.


In combat, the player character does +10% damage against opponents of the opposite sex. Outside of combat, one sometimes has access to unique dialogue options when dealing with the opposite sex, similar to the Sex Appeal trait. In Fallout: New Vegas, it is complemented by the Confirmed Bachelor perk.

Additional dialogue optionsEdit

Fallout 3Edit

Fallout: New VegasEdit

  • One can flatter Old Lady Gibson into giving them the Thrust control modules for free during the quest Come Fly With Me.
  • One can make Janet immediately fall in love with Jack during the Young Hearts quest.
  • A hooker named Dazzle in the courtyard of Gomorrah will have sex with the player character for fifty caps instead of 100.
  • One can flirt with Lady Jane to have her pay her debt to the Atomic Wrangler.
  • One can invoke some humorous dialog between you and The Lonesome Drifter; he informs you that he lived in Montana and his father left before he was born. The player character has the choice of worriedly asking "Montana? Oh god, you wouldn't happen to be seventeen would you?" to which he replies in the negative, and the player character responds by attempting to change the subject.
  • One can compliment a ghoul or human female prostitute on a lower Brimstone table in Gomorrah during How Little We Know in exchange for Cachino's location.
  • One can imply that Cass is flirting with you, to which she will say their relationship will not go any farther.
  • One can access some unique dialogue options, and eventually seduce Light Switch 02 in Old World Blues.
  • In Old World Blues, one can talk to Dr. Dala about their breathing for the quest Coming Out of Her Shell.


  • In Fallout 3, this perk does not carry over to super mutants, feral ghouls, or swampfolk, as they are classed as creatures by the game, and therefore would not be subject to any gender-based effects.
  • In Fallout: New Vegas, dialogue choices from these associated perks do not count as speech successes.

Behind the scenesEdit

The term "Lady Killer" is slang, dating back to the 19th century, referring to a man who is very popular and/or influential with women.
