Vet utility H40
 Veteran Build - Warhammer 40k: Darktide 

No frills H40 veteran with bolt pistol. Standard smoke setup with utility and res-shout.

Aim your gun, shoot stuff far away, throw smokes to "close doors" or to act as a psyker bubble. Res shout is a new addition to the vet lineup due to the buff and acts as an instant clutch in those chaotic games where multiple people go down. 

Spam smokes - saving them is pointless when your whole strategy is to regen them off Demolition Team and Demolition Stockpile. If your team is ever fighting outside of a smoke, you're doing it wrong.

Personally I think Target Down! can be swapped out for another node of choice such as Trench Fighter Drill, Exhilarating Takedown, Volley Adept and Grenadier, depending on if you want to lean more into toughness, anti-elite or utility. Grenadier is the worst of these as smokes generally do not need to double up. 

Shock maul brings a bit more utility due to Skullcrusher on bosses while still having serviceable damage and horde clear. This build is serviceable with the tac axe (prefer Mark VII but you can also use the lightest one for a nice triple special stagger combo), combat blade or duelling sword. I prefer not to use power sword with this build as it lacks the usual melee Trench Fighter, One Motion and Skirmisher. 

Shock maul combos:

• Horde clear: L > H repeating
• Safe horde clear: push attack > H > L repeating. Note that the L can go back into H and you get the horde clear loop, so you don't need to push every time. 
• Single target: H > L (double overhead) repeating. Can chain into special if you like for nice stagger.
• Boss: open with special or H > L > special so you apply skullcrusher. Then H > L repeating. 

Pistol combos:

• Anti-elite: hold down right click, press left click. Wait for surgical to proc for better sniping.
• Horde clear: press swap weapon or dodge button
• boss killing: left click x 4 (max out bleed stacks), re-apply to maintain max stacks until dead
