A while back my old GM tobiasekwall posted in the Swedish corner about how to make weapons differ from region to region and from manufacturer to manufacturer. He mentioned aesthetics such as having Algolian weapons be sprayed black & plasticy, Miran weapons having wooden inlays in the stock and Dabarian pieces having the pipe be an almost statuesque cast that resemble the mouth of a mythical creature. He also mentioned having weapons get special traits, maybe certain acc-weapons don't work properly in non-standard G. Maybe certain vulcan weapons require standard atmospheres?
Based on that I made a little list of attributes to throw in to allow for both low grade, high grade and specialized weapons. Take, change and please give feedback.
The weapon is home made, a shabby job or perhaps it is old and rusted through. No matter the reason the weapon is unreliable. At every shot the first six must be re-rolled. Can be taken in different levels, more levels, more sixes that need to be re-rolled.
Well made - precise
The weapon is masterfully made, has been modified by a weapon connaisseur, is specially ordered or is in some other way better than a factory line made one. At every shot, one die may be re-rolled. Can be taken in different levels, more levels, more dice that may be re-rolled.
The accelerator in this acc-weapon whines and hisses. The weapon does not have the silent trait.
This acc-weapon has a sluggish accelerator. The range is reduced one level.
This vulcan weapon has a tendency not to activate the internal detonators of its shots. This results in the small rockets hitting the target without detonating. The GM can spend 2 darkness points to have the weapon deal no damage, and 1 darkness point to change the damage to that of a primitive rifle.
This vulcan weapon can with a setting have the shots detonate with a delay. If delay is active, half the sixes of an attack can be saved to an attack on the next round. Other sixes are forfeit.
Chain shot (streak vulcan)
This vulcan carbine has advanced tracking that makes the rockets in the same salvo follow the same vector. The risk is that if the first rocket misses, then all rockets miss. The reward is that if there is a hit the damage is greater and it punches through armor better. The weapon bonus is reduced by 3 but gains +1 to damage and the armor-piercing trait.
This vulcan weapon has been combined with an acc-mechanism that launches the rockets before they are activated. The weapon gains the extreme range. But for attacks at short range and closer the rockets do not have time enough to activate and the weapon is treated as a primitive rifle.
Due to damage or design this weapon does not have a proper magazine. Ammunition must be added after every shot. The weapon gains the single-shot trait.
This weapon either has a reduced magazine or is more demaning of cells. It requires a reload after only two quick shots in a round and after a normal shot & a quick shot in a round. The GM can also spend only 2 darkness points to cause the weapon to sieze fire.
The weapon has spikes, spines, images of menacing djinn or skulls. Whatever it is the weapon gives a threatening impression. It gives a +1 bonus to threaten with manipulate. And the first extra six used to cause stress damage causes 2 points of stress instead of 1 point of stress.
The weapon has a built in melee weapon. Either a bayonett, a blade built into the pipe or a knuckle duster on the handle. The weapon can be used as a melee weapon. Which melee weapon depends on what weapon is modified. Consult with the GM, but primitives or cell-driven daggers, swords, axes, spears or staves could all be possible
This weapon only works in certain atmospheres. Perhaps it only works on earth-like environs or works poorly in low-oxygen or in a vacuum?
This weapon only works as intended in certain temperature ranges. Perhaps it siezes up in the cold or overheats in warm climes.
This weapon is not adjusted to gravitational pulls other than standard 1 g. Perhaps it works poorly in low g, perhaps in high g.
The weapon has a built in intelligence that with sensors scans and monitors the battlefield. The weapon can be programmed with voice commands and can also give tactical advice. Gives a +1 bonus.
The weapon has been affected by the dark between the stars. It always causes both victim and user one point of stress on hit.
The weapon is blessed by the icons. It is more effective against darkmorphs. Against them the weapon can have one (or several) of the following traits. Increased bonus, increased damage, reduced crit-value.
