Cauterize: Anyone Incapacitated by a laser blast adds +2 to his Vigor to keep from Bleeding Out.
Overcharge: The lasers below can overcharge to cause an extra d6 damage, but if any of the shooting dice are a 1, the weapon must cool down for a full round before it can be fired again.
No Recoil: Pistols, SMGs, and rifles ignore the Recoil penalty. Gatling lasers still take the penalty which is why they are traditionally mounted weapons.
