Vengeance (Fallout 3)

Vengeance : A very high powered Gatling Laser. Vengeance can be found in the Deathclaw Sanctuary, located in the Northwest corner of the map. The Sanctuary is filled with a ridiculous amount of Deathclaws so prepare for a fight. The Vengeance itself is found in a pool of blood and guts deep inside the Sanctuary, partly hidden by an overhanging rock formation.
