...And Know Disintegrations is a challenge in Fallout: New Vegas.

Challenge requirementsEdit

The player must disintegrate 32 enemies with laser weapons.


Grants 75 XP upon completion.


  • All disintegrations (i.e. critical hits with energy weapons) count for this challenge, so plasma weapons can be used as well as the laser weapons mentioned in the in-game description.
  • This challenge is not repeatable.

Behind the scenesEdit

The name is a reference to Star Wars: The Empire Strikes Back, when Darth Vader tells Boba Fett "...and no disintegrations" when trying to capture Han Solo.

For example, if you create 4 goo piles and you leave the area with a challenge score of 4/32, when you come back to this area again, your score will increase to 8/32. [verified]
