MIDAS

MIDAS uses a G-Element structurally similar to gold to catalyze a seemingly totally clean form of nuclear fission.

While theoretically useful for generating power, MIDAS holds great promise as a weapon of mass destruction iterating on the G-Bomb concept.

When used as a weapon, MIDAS -- like a G-Bomb -- leaves a perfectly spherical blast radius; affected areas look as if something has been scooped out of the wall.
