Grenade (Plasma)

 is a Throwing weapon in Fallout, Fallout 2, and Fallout Tactics. But is an explosives weapon in Fallout 3. Plasma Grenades create a blast of superheated plasma upon detonation.

Fallout and Fallout 2
A magnetically sealed plasma delivery unit, with detonating explosives. Creates a blast of superheated plasma on contact. Mainly used by the Hubologists and Mercenaries (in random encounters) but also by the Enclave as well. Not recommended to use them against the Enclave soldiers as their Power Armor can absorb around 50-80% damage.

Fallout Tactics
Description: A magnetically sealed plasma delivery unit, with detonating explosives. Creates a blast of superheated plasma on contact.

Note
End-game weapon of grenadier, plasma grenade delivers good all-around punch and is abundant enough to make using it feasible as main weapon in the last few missions. However, its value is somewhat detracted by the fact that end-game revolves around fighting robotic forces, which are prime targets for Pulse Grenade. Thus, it`s best to use plasma grenades as soon as they become available, and don`t attempt to conserve them.

Fallout 3
The Plasma Grenade is a magnetically-sealed plasma delivery unit, with detonating explosives, creating a fiery blast of green superheated plasma on detonation, with a high chance to cripple limbs. A critical hit will reduce the target to green goo. It seems to have the same blast radius as its less powerful variant, the Frag Grenade. They are only used by Enclave Officers and Smugglers, introduced in the Point Lookout add-on.

It is also possible to plant a live grenade on an NPC by passing one from your inventory to the NPC's inventory via pickpocketing. This will kill the NPC, regardless of how much health he has, but far more common grenades such as the Frag Grenade can do this too.
