Twin-Linked
(Rule)Description: A set of twin-linked weapons count as a single weapon of that type, but to represent their fusillade of fire you may re-roll the dice to hit if you miss (including twinlinked blast weapons). In other words, twin-linked weapons don’t get more shots than normal ones, but you get a better chance of hitting with them.
Twin-linked template weapons are fired just like a single weapon, but they can re-roll the dice to wound. When fired against a vehicle, you may re-roll the armour penetration dice instead.
