Boltgun Vet. - Mini Spice Mareeeenz!
 Veteran Build - Warhammer 40k: Darktide 

(Video will come soon, I promise!)

Roboute Guilliman's Seal of Approval Edition! This build will destroy heretics with ease, while keeping your team alive.

The main highlight is Locke Mk IIb Spearhead Boltgun. It can 4-shots Crusher and 3-shots Mauler, as long as you keep aiming at the head.

Puncture as precaution if heretics are still standing and Pinning Fire / Shattering Impact / Cavalcade to further increase your damage.

Couldn't go wrong with Catachan Mk III Combat Blade as your melee armament. Fast exploration and ammo gathering is the strength of Combat Blade. You can switch to any of your favorite melee, because 80% of the time you will use Boltgun. But for melee it is recommended to one that have fast mobility similar to Combat Blade.

Exhilarating Takedown, Close Order Drill, Confirmed Kill, Iron Will, and Voice of Command is amazing toughness damage reducer. This will allow you to almost ignore normal mobs damage, making it a great self sustain. Focusing on elites and specialists is the key strategy of this build. I have the lowest HP damage taken on a lot of Auric Maelstrom run.

You're going to need One Motion, since we pick Voice of Command and not Executioner Stance.

Another perk you can switch are between Field Improvisation or Charismatic. The Boltgun is strong enough to one-shot or two-shots every elites and specialists (except for mutant), even at short range (which negate the effect of Long Shot). So, in my opinion, the one needing more attention are the support aspect, which is why I pick Born Leader and not For the Emperor!

Tactical Awareness will allow you to spam Voice of Command. This will be boosted if the mission has modifiers such as: Waves of Specials, Hunting Grounds and Hi-intensity Engagement Zone. The biggest weakness if the mission has Scarce Ammo modifier.

Another thing to note is this build is ammo hungry. You're going to have a lot of kill-counts, but you're going to need a lot of ammo too.

If you're going this route in Havoc, you need to tell your teammate that this build is super ammo hungry and they're unfortunately need to reserve their ammo for critical situation only. So team composition must be Melee focus Zealot, Melee focus Ogryn, and Staff or Smite focus Psyker.
