Nux is an elite spectre outlaw that Tychus can recruit in Co-op Missions. He can use an ultrasonic pulse ability that does area-of-effect damage in a small area, which pairs well with Tychus's ability to pull enemies into a small area with his upgraded Shredder Grenade. Unlike the base spectre unit, Nux cannot cloak of drop nukes.
Fires pulses of ultrasonic energy that lasts 5 seconds, causing 20 damage/second to enemy units in the target area. Does not damage friendly units. Holds up to 3 charges.
Nux's bio is a possible reference to Samwise Gamgee as portrayed in the film adaption of Fellowship of the Ring. Upon being caught evesdropping by Gandalf, Sam utters "I heard a good deal about a ring...and a Dark Lord...And something about the end of the world."
