[Ultra-Tech] Errata in weapons lists?

For example, for a 5.56mm round, you an LD under 3 gives you pi-, an LD of 3-6 gives you pi, and a LD over 6 gives you pi- again. This is the "flechette effect" - a long, narrow projectile actually produces reduced wounding in flesh due to (I think) lack of tumbling. Special rules also apply for both very low and very high velocity (the rules do generate reasonable results with arrows, as well).

This really is very interesting. I'll keep my fingers crossed for the gun-design system.

While you are in here and making us happy, can you comment on whether storm carbines being pi++ is a typo or intended?

And what would be the stats of a Gauss Rifle firing 6mm or 7mm rounds with an aspect ratio of less than 6? I'd imagine the basic damage would be higher than normal, but it would lose its AD(3). Would +1 per die of damage and AD(3) reduced to AD(2) be fair enough for APHC rounds in Gauss weapons? With Gauss ball ammo inflicting +1 per die of damage, pi damage and no armour divisor?

The Gauss weapons are particularly opaque in design, making them very hard to reverse-engineer and tinker with.

Well, say you drop the LD to 4 (I think it's calculated based on LD 8) but up the diameter to about 6.5mm. Running it through the formula, the net results are:

* x1.1 base damage
* +1 bulk
* x0.7 to 1/2D range and about x1.1 to max range
* double the power requirement for the gun
* about 1.5x weight and cost of the weapon itself
* about 1.33x increase in Rcl
* About 1.18x increase in ST
* a bit over 2x increase in ammunition weight (or halving of number of shots)

This is with the same ammo, i.e., retaining the (3) armor divisor with APEP. Going to APHC only reduces the armor divisor to (2).

So Gauss weapons are using APEP rounds? Why is the CPS so low then?

And to clarify, was this the result of upping the caliber of a Gauss Rifle, 4mm to 6.5mm?

Ok, is this one an erratum?

On p142, should the Portable Railgun have its ammo type listed as 10mmG? G seems to stand for grenade, but the damage doesn't correlate with other grenade weapons, and the larger 40mm Railgun isn't listed with G ammo either.

The text on p141 describes the rounds as slugs, but then the ammo table on p143 repeats the ammo type as 10mmG and this is the only weapon that uses 10mm EM rounds (whether G or not).

And before anyone asks, I'll report via official channels too.

The portable railgun table entry and ammo type should be 10mm.

The gauss weapon rounds are the functional equivalent of APEP in that they're firing finned darts, I think.

Storm carbines and storm rifle at pi++ is a typo for pi+.

Thanks. To be honest I would have changed them to pi+ even if it wasn't a typo. Storm Carbines at pi++ is too much of an "ultimate" weapon, and I think it's funnier if there is reasons to use a variety of weapons depending on mission.

Finned darts.

Thanks, I really wondered how Gauss ammo looked.

Are those subcaliber darts with some superconducting sabots or does 4mm refer to the size of the dart?

Urban Assault Weapon: shotgun barrel should be 4d damage
Underbarrel Grenade Launcher: Acc 3 (not bonus).
Splat Gun should ideally use very rapid fire rules and Mortar Boxes should also use very rapid fire rules, or whatever ends up being used for precision burst.
Sniper Railgun, Gauss Rifle pi-
Portable Railgun Acc 8
Underbarrel EMGL 4

Incidentally, the Gauss Rifle is more or less consistent with a weapon firing a 0.006 lb. APEP projectile at just over 4,200 feet per second, except it should be Acc 5 and do 6d(3) pi-.

Since the Weapon Design Rules, while functional, remain vaporware, some weapons in UT were not modified if deviated too much from Basic Set.

(On Accuracy: You lose one point from Acc if the projectile L/D ratio is under 4:1 or the caliber is below 7mm.)

Quick question...does this mean the Gauss HMG, which is also 7 mm., should be listed as 16d(3) pi-? (It's listed as pi.)
