Changes

The crystals needed for the weapon to fire, are taken from a mineral vein on the [[Mining World]] [[Cinderus XI]]. Created when [[Heretic]] [[Psykers]] were slaughtered and buried beneath the lava rivers on the planet, after a failed plot to kill the [[Planetary Governor]], the crystals cause a loud crackling nosie noise to be emitted by the Volcano Cannon when fired. This noise, which some claim are the final screams of the the dead Psykers, has been known to drive those who fight beside the weapon insane; though the tank or Titan crews themselves have never been reported to suffer from these ill effects. As a result units of infantry escorting vehicles and Titans using the Volcano Cannon are subject to periodic purges. The Imperium sees this as an acceptable price to pay for deploying such a devastating weapon on the battlefield.{{Fn|11a}}

A [[Reaver Battle Titan]] can mount a Volcano Cannon only on its two arm mounts,{{Fn|3}} while a [[Warlord Battle Titan]] can equip Volcano Cannons on each of its arm or armor carapace hard-points.{{Fn|4}} The massive [[Imperator]] Titan can carry up to six on its carapace hard-points.{{Fn|5}}

Was said to be even more powerful than the current MkIV, but was never used in service due to being to too volatile. When the Teracharge was fired it almost always destroyed the arms of the Titans and hulls of the tanks that carried it. As a result , it was ultimately determined to be a failure by the Adeptus Mechanicus.{{Fn|11a}}

In the original [[Adeptus Titanicus (game)|Adeptus Titanicus]]-era material, the Volcano Cannon was refered referred to as the '''Defence Laser'''{{Fn|6}}
