Graviton

Graviton weapons alter the target’s local gravity field, transforming protective armour into crushing force.
When a weapon with the Graviton quality hits a target, it inflicts additional damage equal to the target’s Armour points on the struck location. If the target is a vehicle or cover, it instead inflicts additional damage equal to the Armour points of the facing that the attack struck. Vehicles that suffer Critical damage from Graviton weapons always roll on the Motive Systems Critical Effects table, no matter what location was actually hit.
