Path Clear
 Veteran Build - Warhammer 40k: Darktide 

Build Hinges on the Bolt Pistol Blast Radius being 6m~ and you want Flak + Maniac as you aren't using it for Ogryns or Scab Ragers
Chain Axe softens those targets up and Krak Nades will deal with any Bulwark spam or Boss Spam

Chain Axe Second Blessing can be Any of your Preference but Headtaker is the best Overall and Consistent

Bolt pistol having the High Stagger Allows to stun Gunners without Infested Buff into either suppressing them or stagger out of their volley. This also stacks with Execution allowing the Bolt Pistol to deal an Extra 20% more damage in that 6m Radius

If your Team is lacking Space then you can use the Bolt Pistol as an Impromptu Grenade Launcher with its 6m Blast Radius to stagger groups and Shooters. DO NOT try to use this against Crushers as the Ammo Investment to take them down is not worth it unless you are staggering the enemies that surround it to separate the Crusher from the Horde. The Chainaxe can Deal with anything the Krak can't.

Chain Axe with Headtaker Heavy spam + Bleed should soften hordes if your bolt pistol can't be used
Preferable that you get a Melee kill to activate Agile Engagement and swap to the Bolt Pistol to give your Blast Radius that Bonus Damage

Born Leader and Demo Team are used together to top off your Kraks should boss spam be an issue, other reason for Born Leader is so that if you chain kills with the Blast Radius on the Bolt Pistol and Confirmed Kill with VOC. It allows your team to regenerate a decent amount of toughness while being in decent distance of one another and enables you to keep Survivalist active.

Big Issue with this Build is you become Very Ammo Hungry and Starved as this relies on the Bolt Pistol being used more Liberally, thats why Survivalist being active for the entire duration of a mission is Paramount.
