...And Know Disintegrations

"Disintegrate 32 enemies with laser weapons"

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

Effects

 * Completing the challenge grants the player 75 experience points

Requirements

 * The player has to disintegrate a total of 32 enemies using energy weapons. Although the description suggests otherwise, both laser and plasma weapons count, as long as the enemy is turned into a pile of ash or goo.

Behind the scenes

 * The naming of the challenge is a reference to Star Wars: The Empire Strikes Back, more specifically, Darth Vader's mandate to Boba Fett: "...and no disintegrations" when he hired the bounty hunter to capture Han Solo.

Bugs

 * Due to the way the game handles ash and goo piles, the game will increase the challenge counter whenever the player re-enters a cell where either was created.
