The Stealth Boy is a torso power armor mod in Fallout 4.


When installed on power armor, the Stealth Boy will enable stealth mode when crouched, at the cost of one's Action Points, effectively rendering the armor's user almost invisible.


In order to craft the Stealth Boy a power armor frame with the desired torso piece attached must be installed at a power armor station.
