"A hand grenade that releases a high-voltage electric shock."
The Shock Grenade is a thrown explosive weapon that releases an electric blast. It is particularly useful when thrown into a body of water.
Resident Evil: Revelations
In Revelations, the shock grenade serves as a weaker version of the standard hand grenade, doing only slight damage to most enemies within the blast radius. This weapon really shines when tossed into water. When used in this fashion, the electric blast is considerably stronger and the blast radius seems to be bigger as well. The blast is so much more powerful, in fact, that a single shock grenade can kill several enemies that are close together. This makes this sub-weapon extremely effective against packs of Ghiozzos and Sea Creepers.
This weapon's splash damage can injure and stun the player if thrown too close. As a result, this weapon can not be thrown when the player is swimming, unlike the Pulse Grenade.
