When shooting with an organ gun, roll two Artillery dice before making any rolls To Hit. The number of shots fired is equal to the total of both Artillery dice:

• If a 'Misfire' is rolled on one of the Artillery dice, the complex firing mechanism displays one of its all too common faults. All shots fired from the organ gun this turn suffer an additional -1 To Hit modifier.

• If a 'Misfire' is rolled on both of the Artillery dice, no shots are fired and a critical fault has occurred. Roll immediately on the appropriate Misfire table to determine exactly what.

After determining the number of shots, roll To Hit for each as normal, using the crew's Ballistic Skill and applying all appropriate modifiers.
