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 suits, belonging to the Black Ghost counterinsurgency/terror units. Though the Stealth Boy is more portable and capable of projecting a more powerful stealth field, it has severe drawbacks.

The effects of the stealth field only last for about an hour, at which the Stealth Boy will run out of power and require recharging if possible. Also, repeated usage has been found to have unpleasant mental side-effects on the user, as was found by the Brotherhood of Steel, who quickly discontinued it in light of this discovery (see Circle of Steel).

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. It was going to appear in the canceled Fallout: Brotherhood of Steel 2 as "Stealth Girl", as it was usable only by Scarlet, a female character.

Bugs
The use of the Stealth Boy while in combat with non-hostile NPCs and then crouching causes combat to stop. The NPCs revert to being friendly. The stealthboy completely ends any and all agression to the player from friendly NPCs on the spot, even if provoked.
