A hand grenade is a thrown weapon that appears in all of the Fallout games. Most contain explosives designed to inflict damage in a wide blast radius by the fragmentation of their outer cases. Other types of grenades are used to disperse chemical or gas agents, ignite targets or materiel, cause electromagnetic pulse waves, release clouds of ionized plasma, stun targets with bright flashes of light and/or loud sound or create smoke as a means of concealment. Due to their varied nature, different grenade models may be more effective against some targets, and less effective against others. __TOC__
