Mercy

 is a weapon in Fallout: New Vegas. It is a unique Grenade machine gun. It uses 40mm grenade ammo. It can also use incendiary grenade ammo.

Characteristics
Its higher damage comes at the cost of using 40mm Grenades, which is less common and more expensive than 25mm grenades. Cannot be modded, fires much slower than modded Grenade machine gun. However, a normal grenade machine gun equipped with a Grenade MG High-Speed Kit and high explosive rounds will out damage mercy, its unique variant.

Location
Dead Wind Cavern - By a dead Brotherhood of Steel soldier, guarded by many Young Deathclaws, Deathclaws, and the Legendary Deathclaw.
