Venom cannon

An Operative cannot perform a Charge, Fall Back or Normal Move action in the same activation in which it performs a Shoot action with this ranged weapon.

Each time a friendly operative makes a shooting attack with this weapon, subtract x from the Defence of the target for that shooting attack. x is the number after the weapon's AP, e.g. AP1. If two different APx special rules would be in effect for a shooting attack, they are not cumulative - the attacker selects which one to use.
