I just started GM'ing for the first time ever with Dark Heresy, since of our RP group I know the most about 40k settings enough to get the setting just right. After a very slow start where most of the PCs were rolling 80s and failing consistently we got to the end of our campaign and they were getting the hang of the system and how best to use it to murder anything. By the end they were rank 3s and thru the grace of the Inquisitor one Scum was able to get a combat shotgun and the guardsmen got a heavy stubber. Let's just say anything coming at them was shredded. The stubber did have the 40 round drum mag so was only good for 4 turns before needing a reload, and the guardsmen would brace and all that to use it, but most encounters are happening in close range areas so normally most are withing "Short" or "Point Blank" range. Same for the shot gun, which gets extra shots for being scattered. I guess it can all be chalked up to good rolling and can't help it, but I was wondering what other people have thought about this.
Should I just not let them have those really nice weapons at a low level? But even if we continue and they make rank 6, they'd have stuff like that, or even a Boltgun maybe for the Guardsmen, so it'd be even crazier. The other part to this is a lot of stock monsters come with 8-14 wounds, and anything with Auto or Scatter will consistently put out damage to drop those in one turn. Should I be upping the number of monsters per encounter or just upping Wounds to compensate? Like we did the Edge of Darkness campaign and the final battle with the Churgeon boss and her scalpel familiar was laughably easy, so I just plot armored the familiar so it could at least get a couple attacks in before dropping to the hail of bullets at point blank. The group as a whole did sit down after the credits rolled and the players agreed it seemd a bit OP, so I'm not the only one, and they'd be willing to have a session before the next game to agree on some balance rules, like reduce the guns that full-auto from 1d10+4 to like 1d10+2 (or 1d5+4), but retain the normal stat line if they fire single shot. A justification basically being you're pelting the target with innaccurate bullets, so they might just be hitting arms and legs winging you.
Any suggestions or tips? Thanks!
