Some missile weapons enable their users to shoot several times – this is known as multiple shots. The number of times the weapon can fire is given as part of its description (e.g. a Dark Elf repeater crossbow can fire two shots, so it is noted as having 2x multiple shots). These weapons can either fire once without penalty, or as many times as indicated in their rules with an additional -1 to hit penalty. All models equipped with such weapons in the unit must either fire multiple shots or single shots, the player cannot choose to fire single shots with some troopers and multiple with others.
Remember that a model's Attacks characteristic has no effect on the number of shots it fires. The Attacks characteristic refers to close combat attacks only.
