Editing Exterminatus (section)

===Cyclonic Torpedoes===
The primary method of Exterminatus used in the 41st millennium, these are basically skyscraper-sized nuclear missiles that've eaten their weight in steroids. These capital ship-fired warheads each generate a series of massive, self-sustaining nuclear reactions, which, when fired in bulk, fuels a much larger reaction that causes the devastation to spread and multiply, eventually glassing the entire world with a thermonuclear holocaust given a sufficient barrage. If you fire enough in the same spot it will break through the crust of a planet, causing part of the mantle to erupt out and royally buttfucking the entire planet in the process ([https://www.youtube.com/watch?v=FYXj9xOUFIM see the ''Fire Warrior'' end cinematic]).

[[Krieg]] is an example of a radioactive perpetual-winter world that survived multiple cyclonic torpedo strikes, though in this case it was on a much smaller scale and in some sources are described as standard nukes. This was the method that killed Typhon, in combination with the above shoot-the-shit-out-of-it method. (Another theory holds that the bombardment is used to remove anything that might prevent the torpedo from reaching the surface or to weaken planets crust.) Only the [[Inquisition]] and the [[Space Marines]] are authorized to carry cyclonic torpedoes in their warships, the former because the Inquisition has the authority to do anything, and the latter because the Imperium figures that if the Space Marines can't beat it, nothing else will.

Cyclonic Torpedoes are pretty variable in their strength, either due to there being different classes of torpedoes or the fact that the strength of a single torpedo has never been nailed down in official materials. In one case, ol' [[Abaddon|Abby]] dropped a dozen to fry a single hive; in another a single torpedo is a qualified planet cracker. Similarly, this method is the easiest to thwart with shields, as they disrupt the stacked efficiency needed for ongoing detonation. Presumably this variability in strength is due to "Cyclonic Torpedo" being as broad a description as "atomic bomb", which can refer to both a Davy Crockett and a Tsar Bomba.
