OK, I actually decided to write this up pretty-like.

Railguns

The To-Hit dice are cored in the same manner as Pulse Torpedoes
Range 0-6, 2+ hits
Range 6-12, 3+ hits
Range 12-18, 4+ hits
Range 18-24, 5+ hits
Range 24-30, 6+ hits

For each hit, roll another die for damage. Add the class of the Railgun to the
roll. Subtract the target's Armour Level (Kra'Vak type, not human). Any roll
lower than 1 is treated as a 1.
Roll 1-4, damage = RG class
Roll 5-6, damage = 2 x RG class

That's it.

Now for the number crunchers

Average damage at range

Range RG1 RG2 RG3
0-6     1.25    2.78    4.58
6-12    1       2.22    3.67
12-18   .75     1.67    2.75
18-24   .5      1.11    1.83
24.30.25.556.917

That would allow us to balance as

Class 1 Railgun, 1 MASS, 2-arc
Class 2 Railgun, 2 MASS, 1-arc
Class 3 Railgun, 4 MASS, 1 arc POINT COST = MASS x 4(?)

Don't these and other figures show that massed class 1's are still
significantly better than 1 class 3? Except perhaps against integral armor
which is the less common case.

No. Just as for Beam weapons, Class 2s are the "best buy." As shown above, per
MASS, a class 2 outperforms a class 1 slightly. In other words, 2 Class
1 RGs are slightly worse than 1 Class 2 RG. Class 3+ RGs, though capable
of doing alot of damage in one strike, have a slightly lower efficiency.

If I don't divide for mass above, 2 Class 1s are 2.5, but 1 Class 2 is
2.78.

3 Class 1s are 3.75, and a Class 3 is 3.45

It mirrors Beams fairly well.

I couldn't stay out if the disscussion;) My quick thoughts.

> Schoon Wrote:

I worked out all the numbers like I did before and they seemed just a bit off.
So then I thought about modifying the damage roll to:
1-5, damage = RG class
6, damge = 2xRG class
This makes RG2's at an unarmored target do 2 pts on a 1-3 and 4 pts on
4-6.
It also allows a RG4 to do 4 pts on a 1 and 8 pts on roll of 2-6.

Then number crunching away we get:

I did a cost of 5 per mass and everything seemed to work out well. I'm happy

Yup, that is how I understand it (using my variation to Schoons original
mechanic). It also gives the RG a bit of the reroll feel that on a modified
damage roll of 6, damage is doubled, but in the end the weapon is balanced
with the non-reroll Pulse Torpedo.

Class 1 Railgun, 1 MASS, 2-arc

You get 4:1 class 1's to a class 3

Range RG1 RG2 RG3
0-6     1.25    2.78    4.58

4 class 1's are 5.0 and a class 3 is 4.58 plus the class 1's are 2 arc and
less prone to threshold rolls. I know what I'd use in 'wheenie mode'.

I suggest raising the mass of class 1 to 2.

<some big snips above>

Dean,

If I read this correctly, your verison of the 'K' railguns drops in power from
there FTMT counterparts. In FTMT we see that they Rainguns did damage
on 1-4 class rating, and 5-6 Double class rating. Yours shows 1-5
standard, and 6 double. I don't think I like the idea of making the Kra'Vaks
any weaker.

Lets look at in a new light, take the most powerfull Human weapons, and scale
the Class3 or 4 railgun to that level and see what happens..

Just a thought..

Here we go again.. We can never stop 'wheenie mode' so lets stop trying..We
are just trying to move the Kra'Vaks into the Fleet Book..

Lets start seeing some more Alien approaches, to the 'K' railgun rules..

Bouncing in for just a quick minute!:)

> I couldn't stay out if the disscussion ;) My quick thoughts.

How does this make them weaker? I mean, if you look at the details of what
Dean wrote up, I don't think it makes them weaker at all. Also,
it gives a differentiation between the Class-1s and the Class-3s; the
Class-3s are more prone to doing double damage than the Class-1s.

Whether this is a good thing or not...welll...  ;-)

Formula:  Damage = Die Roll + Weapon Class - K'Armor Rating

Thus:

Two K'Guns are fired, a Class-1 and a Class-3, at the same target (a
human ship). Both guns hit. Damage roll time. For both guns, a '4' is rolled.
For the Class-1, this means: 4+1-0 = 5. In Dean's system, anything <6 is
Class-damage, so the Class-1 does 1 pt. The Class-3, on the other hand,
does: 4+3-0 = 7, which is greater than 5, which means double damage,
which means 6 pts (ow).

Now, unless I'm missing something ('cause I haven't the time to number crunch
like Oerjan does;), it seems like a reasonable variation. If not for the
Kra'Vak, then someone else.

Okay, returning to lurker mode and back to work...  :-/

If we're not fixing the RG's why not just use them from MT as written?

The reason is that the FB fixed beams so moving RG's into the
FB you should fix them too. The current proposal from Schoon/Dean
actually works OK. And in the latest version the wheenie problem is basically
fixed. You just have to roll 2 die and accept penetrating damage is factored
into the damage multiplier. I'm happy with that, and its a lot better than
going round in circles.

This is Dean/Schoon system with changed mass
to fix the wheenie hole. Penetrating damage (rerolls) is being omitted at this
time.

Railgun
=======
To hit number as pulse torpedoes. Damage roll 1 d6 with modifiers:

1d6 + railgun class - target intergral armour level

The final damage roll value is interpreted

1-5 - railgun class in damage points
6   - 2 x railgun class in damage points

Yes Kurt, neither was I - its from Michael Sandy's rather neat
original calculation - double checked with a monte carlo simulation
of my own.

<Michael Sandy> How much damage, on average, is done by the reroll? Call this
amount 'x'.
x = 4/6 + 1/6*x, or
5/6 x = 4/6
x =.8 points.

So, 1 dice of beam damage can be expected to do
4/6 + .8/6, or 4.8/6, or 4/5 versus no shields.

i.e. 0.8 average damage with reroll per die(no shields/Iarmor)

As long as they cost a lot, fine. Right now (ie, MT rules) they're far, far,
FAR too powerful for their nominal points value.
