The plasma grenade is a weapon in 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, even though criticals deal no extra damage. It seems to have the same blast radius as its less powerful variant, the frag grenade.

Thrown grenades are affected by physics; they may bounce or roll unexpectedly if not thrown carefully. However, in game physics can also be used to your advantage; such as throwing grenades through doorways or bouncing them around corners to attack enemies who cannot see you.

Grenades can be targeted in V.A.T.S. and can thus be shot out of the air. Shooting them whilst they are still held by the enemy can detonate them as well. Grenades can be thrown point-blank in V.A.T.S due to the sharply reduced damage taken.

A grenade that has been thrown toward you will show up on your HUD as a red arrow denoting its direction relative to you. Move in the opposite direction as quickly as possible to escape the blast radius.

Holding the fire button down for a longer period of time will increase the strength of the throw. Grenades can be thrown for longer distances than normal through successful V.A.T.S. hits. Grenades cannot be cooked to detonate earlier.

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

Taking ranks in the Demolitions Expert perk will further improve the damage inflicted by any grenades in your possession, up to an additional 60% damage.
