Nice. It kind of makes things a bit more complicated at the end, but I think 1CP is a good price for it.
I just got another idea for an automatic weapon-type rule. I think the less rules you have to make up and the more rules you can alter make the game better. That way you can just kind of use the "template" for all of the rules.
This one's based off of the missed shot rules:
Gatling Power/Automatic Fire (+2CP)
If a weapon with this ability is fired and the attacker gets a Skill Roll above the Use Rating, the attacker may make another ranged attack on another target. This second target must be within a distance equal to the difference between the Use Rating and Skill Roll in inches as well as in range of the attacker.
This second attack gets +1 to the Use Rating. This may continue until the attacker misses, with the Use Rating continuing to increase by +1 for each additional target past the first.
After the attacker has finished attacking the targets, he applies damage to all targets who were hit, using one damage roll. The first target receives full damage, the next target's damage is reduced by -1, the next by -2, etc.
Example: Frank has a Skill of 1d6 and a weapon with a Use Rating of 3, Gatling Power, and 1d6+2 damage. Bob, Bill, and Brian are all within range of Frank.
Frank attacks Bob first, rolling a 5 for his Skill Roll. He hits! The difference between the Use Rating of 3 and the Skill Roll of 5 is 2", so Frank checks and confirms that Bill is within 2" of Bob.
Frank attacks Bill next, now with the Use Rating increased by +1 for hitting him (4). Frank rolls another 5 and hits! The difference between the Use and Skill Roll is 1, and Brian is within 1 inch of Bill.
Frank attacks Brian, and the Use Rating is now increased by +2 (5 overall). Frank rolls a 4, not hitting Brian.
Frank rolls damage (1d6+2) and gets 5. That means that Bob gets 5 damage done to him. The second target, Bill, receives -1 to the damage, so he only takes 4 damage,
