Against All Tyrants

Against All Tyrants is a three-star (★★★) challenge added in the Fallout: New Vegas add-on Gun Runners' Arsenal.

The Courier must kill any ten named Legion members with hunting revolvers, Ranger Sequoias, brush guns, service rifles, hunting rifles or cowboy repeaters.

Effects
Grants 1,000 XP upon completion.

Behind the scenes
The name of this challenge is a reference to Richard Overton's 1646 pamphlet An Arrow Against All Tyrants, which inspired the American Constitution. It also alludes to the embossment on the barrel of the Ranger Sequoia: "For Honorable Service Against All Tyrants." This second allusion is further supported by the fact that all listed weapons are typical issue for the NCR Army or Ranger corps.
