This Superweapon calls in a bomber carrying an extremely heavy bomb that will freefall into the target from great height. The bomb has a hardened nose and will penetrate the ground, before exploding, sending a shockwave through the ground that will result in the formation of a large crater and cause an earthquake in the area. Damage is dealt through this earthquake and the weapon is only capable of damaging structures.
Notably, because it is designed to create a shockwave in the ground, the bomb is more effective when used next to its target rather than dropping it directly on it.
