Even though it's not a very original name, it describes the weapon very well. It is usually used to clear out massive Swarm attacks. Since it is the only weapon The Swarm aren't given enough time to adapt to. The Red Empire developed the weapon in 2789 in hope to find a way to stop the increase in Swarm attacks. The bomb works buy putting the firing pod in space, setting in the coordinates, then three torpedo like objects fire out, and the second they hit the ground a wave of fire spreads out in all directions. Turning everything within 300 miles to ash.
