Last round

Play this card when activating a fighter that has one or more Out of Ammo markers on them.

Choose one of this fighter's ranged weapons that is
Out of Ammo. The fighter immediately performs a
Shoot (Basic) action with that weapon that will hit automatically. Do not roll an Ammo Die - the weapon remains Out of Ammo.
Weapons with the Rapid Fire (X) trait make only
one shot.
