Or, a new attack action!
[Fire a Full Spread]: The targeting parameters of a macrocannon battery may be modified to cover a wider area, at the expence of raw power. Before any attacks are rolled, the gunner(s) may chose to reduce the effective strength of their weapons battery to give them a bonus to hit, at a 1 str to +10% ratio. This may not reduce the batteries strength below 1.
This sounds better. Allow combining of battery fire so three STR 3 batteries firing at STR 1 each on a single salvo get +60 for a single hit. Assuming a 2 Shield cruiser is the target and a PC at the guns you'd get the equivalent of about three macro hits into armor on a single hit...3d10+1 vs armor (average about 19.5 damage).
