Stealth Boy

RobCo Stealth Boy 3001 is a personal stealth device worn on one's wrist. It generates a modulating field that transmits the reflected light from one side of an object to the other, making a person much harder to notice (but not completely invisible).

The technology was developed by Robert Mayflower, based on captured Chinese Hei Gui stealth armor units, belonging to the Black Ghost counterinsurgency/terror units.

After the war, it was used by the Nightkin elite super mutant units of the Master's army.

Fallout
Nightkin NPCs can be seen using Stealth Boy, however, their usage is entirely cosmetic. Unlike the mechanics of traps, the player does not have to make a saving throw in order to spot Nightkins.

Side effects
Some time after they acquired the Stealth Boy technology, the Brotherhood of Steel experimented with those devices. It turned out that prolonged use causes the user to suffer paranoia, delusions, and eventual schizophrenia. When this was discovered, the devices were banned and the team disbanded. However, it was not known that the team had already begun to suffer the effects of the device. Thinking the disbanding of their team to be a conspiracy, they decided to steal the Stealth Boys and form a new covert operation called the Circle of Steel.

Appearances
Stealth Boy can be found in the first Fallout and Fallout 3, although it is mentioned in Fallout 2 and its description is present in Fallout Tactics files. The device's back story wasn't developed until Van Buren, the canceled Fallout 3 by Black Isle, where it was spelled as StealthBoy to prevent it from being confused with the "Stealth Boy" playing style.

Stealth Boy was to appear in Fallout 2, but only in areas that where cut from the final game.
