The Urugan Cannon has a range of 24" and Strength 5. It has the Armour Piercing (1) and Multiple Shots (Artillery Dice+D6) special rules.
To fire the gun, nominate a visible target and determine how many shots are fired. To do this, roll a D6 and the Artillery Dice: the result is the number of shots fired.
If a Misfire is rolled, roll immediately on the Blackpowder Misfire table. If firing is completed without a misfire, and the target is within range, roll To Hit with all shots as normal, using the Ballistics Skill of the crew.
