Grenade (Pulse)

A Pulse Grenade is a device designed to damage or disable robots and electronics with a short range electromagnetic pulse. It is significantly less effective against humans, mutants and animals. Power Armor is specifically hardened against EMP, and Pulse Grenades are ineffective against it.

In-game description
An electromagnetic pulse grenade, discharging a strong EMP blast that doesn't affect biological creatures. Contact fuse.

Location
Found in Sierra Army Depot, and the basement of New Reno Arms, among other places. Rare.

Fallout 3
In Fallout 3, a Pulse Grenade does only minor damage to biological creatures (around 5-10 points) but is very effective against robots. Most, if not all (Liberty Prime being the probable exception here for obvious reasons) robots are disabled temporarily by the EMP burst, leaving them vulnerable to attack. Upon exploding, Pulse Grenades create an electromagnetic field which tosses around loose objects within it. *Note* Having the Cyborg perk does not make you a robot, thus the Pulse Grenade EMP blast will effect like a normal biological creature.

The only exception is if you Sneak and plant the grenade onto another character, which makes the EMP explosion fatal to your victim. Also works with the mine version.

Talon Company mercenaries usually carry some Pulse Grenades with them. These grenades are the most cost effective ways of dealing with robots. Save them when possible.
