A Electromagnetic pulse grenade is a thrown weapon that appears in all of the Fallout games except Fallout: Brotherhood of Steel. Electromagnetic pulse, or EMP, hand grenades have little wounding effect to organic targets. Instead they create a powerful magnetic field that induces high currents or voltages in the effected radius, damaging electrical circuits or disruption their function. Unshielded electrical or electronic devices are particularly susceptible to EMP damage. __TOC__
