Grenade (Pulse)

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

Fallout 3
In Fallout 3 Pulse Grenade does only minor damage to biological creatures (around 5-10 points) but is very effective against robots. When exploded, Pulse Grenade creates electromagnetic field and this field tosses around loose objects within the field.

The only exception is if you Sneak and plant the grenade onto another character, which magically makes the EMP explosion fatal to your victim while doing almost no damage to anything around them. Also works with the mine version.

Talon Company mercenaries usually carry some Pulse Grenades with them.
