Fallout: Wasteland Warfare - Super Mutants - Nightkin

Creations of the Master, Nightkin are elite Super Mutants. Their purple hue is due to increase experimentation on them, though their name stems from near-constant use and almost addiction to Stealth Boys. This makes them some of the most dangerous variants of Super Mutants, as while they are not quite as strong as standard Super Mutants they are stealthier and have more reasoned approaches to combat almost verging on tactics.
