Flash bang

The flash bang is a weapon in the Fallout: New Vegas add-on Lonesome Road.

Characteristics
The flash bang is a type of non-lethal grenade that deals fatigue damage. In addition, they also reduce enemy weapon skills and have a one in four chance of frenzying tunnelers. Upon detonation, the grenade releases a large explosion of blueish-white colored light in a 10-foot radius.

Getting caught in a flash bang's radius causes your screen to either blur or turn completely white (depending on how close you were to the blast). In addition, your hearing is severely affected.

Locations

 * Found on the body of a dead NCR trooper when first entering the collapsed overpass tunnel.
 * Can be found on marked hunters and marked scouts in varying amounts (1-3+).
 * Can be found on the occasional dead NCR trooper or NCR Ranger, typically in caves or other dark areas.
