The MFC grenade is a powerful improvised weapon, created by converting three microfusion cells into a thrown explosive device. It has a wide blast radius and similar visual effects to a plasma grenade.
This weapon can only be gained by taking the Mad Bomber perk; it can either be directly crafted, or the player can gain up to six by recovering the individual mines of an MFC cluster. It cannot be found on enemies or in containers.
The blast radius is wider than a standard frag grenade. It also is slower to throw (at least in V.A.T.S).
It is the least expensive craftable weapon in the game. Requiring only 3 microfusion cells to create, valued at 9 caps total, in return the grenade itself has a value of 15 caps, 6 caps more than what it costs to create it.
Despite microfusion cells weighing nothing (outside of hardcore mode), the MFC grenade weighs half a pound.
Because microfusion cells weigh nothing, if you have ED-E (with Lonesome Road installed) and/ or Veronica Santangelo in your party, you can create MFC grenades on an "as needed" basis, so their weight is no longer a concern.
