Heavy Shotgun
 Veteran Build - Warhammer 40k: Darktide 

Zarona Mk VI Combat Shotgun has good cleave, especially the special round so it is good for hordes. Spam that special round at hordes and you will kill a handful with each blast. At range, it might take 2-3 shots to deal with specialists but I think it's a good compromise to have over Agripinaa Mk VII Combat Shotgun or Accatran Mk III Huntsman's Shotgun . Ammo stock is high, magazine size is high, reload speed is decent and it hasn't let me down so far. Keep in mind blue stimms make this shotgun useless so don't waste ammo on enemies with blue stimms and also don't use it on Crusher unless you absolutely have to.

Turtolsky Mk VI Heavy Sword is as usual, can one-shot Dreg Rager and Mutant with weakspot hits. Heavy attacks deal full damage for the first two targets and miniscule damage to anything after that, so do not use it for crowds. For spread out enemies, specialists, elites etc. heavy attacks are absolutely perfect. For hordes, spam light attacks as they have good cleave and cleave damage distribution. For Crusher and Scab Mauler , open up with special attack which gives brittleness debuff to enemies and then go Heavy > Special to keep the debuff going. First light attack after Special attack can cleave through carapace armor so use it to stagger multiple vanguards and scab ragers at once if you need to.

Voice of Command overall is good team support. If you want full damage, you can go Executioner's Stance. I take Only In Death Does Duty End as it can come in clutch. For keystone I use Focus Target! but nowadays planning to use a build without keystone but we'll see. Mark anything that needs to disappear for a hefty damage bonus.

Smoke Grenade is really good for ranged units, Pox Hound, some specialists so I find it the most utilitarian blitz out of the three.

Now go slay some heretics!
