A magnetically sealed plasma delivery unit, with detonating explosives. Creates a blast of superheated plasma on contact.— Fallout 2 In-game description

Plasma grenades are weapons in Fallout and Fallout 2.


Plasma grenades are very rare but powerful thrown explosives. When detonated, a small explosive in the grenade ruptures the magnetic seal containing a charge of superheated plasma energy.

It is not recommended to use them against advanced power armor as it can absorb around 50-80% damage. However, just about everyone and everything else has a low plasma resistance, making this grenade type the most useful late to end game.



Fallout 2

  • Shady Sands sheriff's department has one in a container.
  • Navarro underground - Four can be found in a container.
  • Sierra Army Depot courtyard, level 2, and 4 have several plasma grenades in containers.
  • Carried by Hubologists in random encounters featuring five standing in a circle, one is guaranteed to have several on their person. Unlike most other situations, failing a steal does not provoke them into hostility and does not damage Karma/reputation, making plasma grenades potentially more plentiful than frag grenades.
  • Sometimes used by mercenaries in random encounters.
  • Sometimes used by the Enclave.
