Railgun System

Electromagnetic accelerator fires solid penetrators at high velocity. The chance to hit a target is the same as torpedo systems.

Symbols:

Range and Rolling To Hit

At range of… Required score to hit
0-6″ 2 to 6
6-12″ 3 to 6
12-18″ 4 to 6
18-24″ 5 or 6
24-30″ 6 only

For each railgun projectile that hits, damage is dealt equal to the class of the railgun. However there is a chance it will deal double the damage instead. Roll another six-sided die to determine the result.

Table: Railgun Damage

Railgun Class 1-3 Rolled 4-6 Rolled
1 one point two points
2 two points four points
3 three points six points
4 four points eight points

* Standard defensive screens do not affect damage dealt by railguns

Advanced Screens

While standard defensive screens do not affect railgun hits or damage in any way, advanced screens are able to reduce the chance of taking double damage.
