Is the hellgun pen correct in rogue trader it is 7 much higher then dark heresy were it is pen 3

Bolters can't fire on full auto in Dark Heresy either, yet in Rogue Trader, they can.

So which one is correct and canon?

Grand Inquisitor Fulminarex said:

Neither. According to Canon, Hellguns have a pen of 6 and Bolters, while capable of full auto, are not capable of semi-auto fire. If you doubt me, just look it up in the Canon. It says this, clear as day, on page 246, second paragraph.

this does not help Compatibility issues much does it

In the new ed. of the tabletop miniature games they upped the penetration of the Hellguns...so FFG followed.
Just treat as different patterns with different stats.

GrtZ,

S.

The RT pen is correct for RT, because, between the release of DH and RT, the hellgun in the tabletop game was much improved, so that it was AP3, which explains the upgrade.

And whilst the games are "compatible", they mean that characters can be transfered, it doesn't mention weapons and equipment. It's as compatible as the oWoD, in that it is, kind of, the same basic system, but you need to houserule to get them to work together, and even then, one will be OP compared to the other.

Compatibility is easy. If your playing a DH game, use DH stats. If you have RT characters, use RT stats. Dh characters that become RT characters, RT stats. Not too hard.

That is, afterall, how they're presented - many of the weapons in the RT book are listed with a pattern name, which differentiates them from other weapons of the same type but different pattern.

Well i Suppose the main issue for me is that well I just don’t think the hellgun should be that powerful it never was in my day blast them
Changing the rules on me
O well rant over

FFG stance is the weapons are simply different from different STs thus the <some_name> pattern hellgun.

Warhammer 40K is a galaxy of guns. There are more different types of weapons in than are discribed in both books combined.

For the most part, when their is a stat difference between weapons and equipment RT equipment is supperior to DH equipment. I don't see much of a problem here. Your DH character's don't shop at the same stores as RT character.

Sure it's not perfect, but it is definatly workable.

In addition to this little "pattern" thing... please take note that the "Hellguns of RT" only work with a energy backpack . Otherwise, they won´t do (see RT Armoury section) while "the Hellguns of DH" work with handy little energy cells. Not the standard "17 megathule" (or whatever), but they work without a backpack.

So, even there wouldn´t be any "pattern", this would logical explain why they have a different performance.

Heh, Something I hadn't noticed, and might make my players think twice about carrying them. They all busy working out encumberence but not taking the 10kg backpack into account - 16kg just for your Lucius Pattern Hellgun; 14kg for the pistol). I wounder why that extra weight wasn't included in the weight column.

Theoretically that'll mean that each clip is going to weight 10kg, rather than 10% of the weapon's weight and it'll take you 2 full rounds to swap out the backpack for a new one and almost impossible if you use the bigger 80 round backpack (pg 135)

Not to mention that would want an "ammonition boy" running with you to carry your extra backpakcs . No, seriously. I think the concept of the Lucius Pattern HE-Weapons is that you will not "reload" during combat.

The "standard 10kg" seem to be your outfigt if you prepare "for a small skirmisch". If 30 or 40 shot of high-powered, armour erasing energy will not settle things, you might be in over your head in the first place.
The large backpack will be "for war". The Lucius-HE seems to be simliar to an "elite weapon". Elite teams are not meant to take the "full load" of a battle but "for special situations". There, 80 shots from a Lucius Hellgun per Squadmember shall do it. If not.... it might be pretty wise to have a non-Lucius-HE Pistole as a side weapon.

All in all, I always wondered why everyone is jumping on this Pen-7-Monsters. The backpack makes them equivalent to the non-military Servosuits. Nice, but not practical or enduring enough to be choice for long-term-usage.
