Catastrophic Damage: Whenever a unit doubles the original threshold value of a machine, creature, capital unit or behemoth the unit suffers an additional internal hit. The number of additional internal hits is increased each time the unit scores a multiplier of double the target unit’s initial threshold. For instance if a unit scores 12 hits on a Zyklops regardless of the current threshold of the Zyklops, the Zyklops takes two internal hits (one for the initial hull penetration and one for the doubling of the threshold).
