BLIP! - Buff those Autocannons

Just a BLIP so you can make those Autocannons fun. PPC's are for chumps.
Autocannons work the same with the following additional rules:
When making an attack, if the attacker is successful and rolled a result above the Target Number, add +2 bonus damage to the attack. If the actual target number is rolled, apply standard damage. Example: A Shadow Hawk fires its AC/5 at a Cicada and needs a 9 to hit. Rolls a 10. 7 points of damage applied. If the result was a 9 it would have caused 5 damage.
