Shock Trooper
 Veteran Build - Warhammer 40k: Darktide 

This build is focused heavily on melee & for players who want a more active, faster paced, and aggressive playstyle with Veteran, without giving up the ability to support the team & deal with high priority ranged targets thanks to the Bolt Pistol, while providing excellent horde clear & anti-specialist/elites (specifically Gunners, Shotgunners, and Ragers) in close range thanks to the Assault Chainsword, and providing a safety net for extremely dense hordes via Shredder Frag Grenades. 

You can run whatever curios you like (except wounds), just make sure you have 20% Gunner Resistance on all of them and at least one toughness curio. You can also swap Shredder Frag Grenades for Krak Grenades if you decide to run a shotgun instead.

Alternative recommended viable melee weapons:
- Cadia Mk IV Assault Chainsword with Maniac + Flak/Unyielding & Rampage + Shred
- Munitorum Mk I Sapper Shovel with Unarmored + Flak & Uncanny Strike + Skullcrusher
- Rashad Mk III Combat Axe with Carapace + Elites & Brutal Momentum + Headtaker
- Atrox Mk II Tactical Axe with Carapace + Maniacs & Brutal Momentum + Headtaker

Alternative recommended viable ranged weapons:
- Agripinaa Mk VII Combat Shotgun with Flak + Maniac & Scattershot + Manstopper
- Crucis Mk XI Double-Barrelled Shotgun with Flak + Maniac & Manstopper + Flechette
- M35 Magnacore Mk II Plasma Gun with Maniac + Carapace & Rising Heat + Gets Hot!
- M35 Magnacore Mk III Plasma Gun with Maniac + Flak & Volatile + Power Blast
- Zarona Mk IIa Quickdraw Stub Revolver with Maniac + Carapace & Hand Cannon + Surgical

You can of course run this build with Infiltrate or Executioner's Stance, however Executioner's Stance will tax you an extra node to reach the required Weapon Specialist perks, or you will have to drop another talent in order to do so.

This build was tested on Damnation & Auric with decent success.
