[FT] My Railgun Variant

Just because someone (I don't remember who, sorry) asked for the reposting,
here are my Railgun rules again, all in one place. I am
going to make use of them myself, one way or another-if not for the
Kra'Vak then for some other hapless alien race.

I am making the following assumptions with Railguns: First, it's not easy to
hit a distant target with one. Secondly, if you DO hit, you inflict major
damage on your unfortunate enemy. (Blame the Colonial Marines Technical Manual
for this. If anyone cares, I can post the relevant paragraphs.) Thirdly,
Railgun damage is consistent, regardless of range. Fourtly, Railguns fire what
is effectively a gigantic cannonball. No, it is not the most logical approach,
but it feels right for the KV. Fifthly, all Railguns are one arc weapons.
Sixthly, Railguns have a high mass and point cost.

Cannon Mode: The attacker must roll HIGHER than the range to the target (in
inches or cm, whichever is appropriate) on 4d6. All sixes are
re-rolled, and added to the previous total. If the attacker succeeds in
rolling higher than the range, he hits.  Damage is equal to 1d6/class of

the gun. Damage is applied half to armor (rounded up), and half to hull.
Example: The Kra'Vak ship "D'mit" fires a Class 3 Railgun at the FSE ship
"Floating Target", 14 inches away. The KV player rolls 4d6, getting 3,6,2, and
2, for a total score of 13. The six is rerolled, producing a five, for a new
total of 18. The roll is higher than the range, so the FSE ship is hit. The KV
player rolls 3d6, for a total of 12 points. The "Floating Target" goes boom.

Simple enough, right? I decided that the "to hit" roll should not vary by
class size, as the size of the shot should not make any significant changes to
the effective range. The use of four dice gives RGs an average range of 13 or
14 inches, if my math is correct, so they are still going to be best at short
range. The rerolling of sixes on the damage dice is optional, but seems a
little harsh under the circumstances. The main advantage of this mechanic, to
my mind, is that

is very simple and requires no charts whatsoever.
