Recently, I’ve been thinking about mechanics for weapon batteries in Sword of Terra. Previously, I’ve simply given multiple weapons to a ship that share a firing arc, but I want some additional restrictions and benefits for weapons sharing a turret. Currently, I’m thinking about using the following rules when a ship has multiple weapons of the same type linked together to form a single weapon battery. Let me know what you think.
Shared Targeting System
In a single round, weapons in a battery can only fire upon a single target. A player may opt to only fire some weapons in a battery at that target, but the player cannot fire any weapon in a battery at a different target than the other weapons in the same battery.
A ship may use the spread fire option to increase accuracy. When making a spread fire attack, the player makes a single to-hit and to-damage roll for the entire battery rather than one set of rolls for each weapon. The spread fire attack has the same power as a single weapon from the battery, but it gains a +1 bonus to accuracy for each weapon in the battery beyond the first.
In an attempt to breach armor normally impervious to a weapon, a ship can use focused fire. As with spread fire, the player makes a single to-hit and to-damage roll for the entire battery rather than one set for each weapon. The focused fire attack has the same accuracy as a single weapon from the battery, but it gains a +1 bonus to power for each weapon in the battery beyond the first.
