Vault 13's Revenge

Vault 13's Revenge is a two-star (★★) challenge added in the Fallout: New Vegas add-on Gun Runners' Arsenal.

Challenge requirements
The player must kill 15 super mutants with 5.56mm pistols, Plasma Defenders, plasma grenades, power fists, Rippers, or the Bozar.

Effects
Grant 500 XP upon completion.

Behind the scenes
This challenge is a reference to the original Fallout and Fallout 2, as all of these weapons, except the Bozar, could be acquired by the Vault Dweller, whose home was Vault 13 and who faced the threat of the super mutant army. The Bozar can be found in Fallout 2, where it can be used against the remnants of the Master's Army with great efficiency.
