The shockwave generator, a rudimentary sonic weapon, was developed by the old Mandalorian Crusaders. It produced a powerful sound wave, designed to obliterate any target struck by the energy it emitted.
Frequently, Basilisk war droids had a nose section made up of several shockwave generator rods. Upon activation, these rods would converge their energy, unleashing a plasma discharge strong enough to penetrate the hull of a starship.
