Havoc 30 Vet
 Veteran Build - Warhammer 40k: Darktide 

All attacks are powered up.

Horde clear:

Push + light + light (main one for me)

Or

Heavy + light + Heavy + light (repeating)

(Monitor your stamina a bit, i use combo 2 to split combo one up to regen stamina in between. Then back to push swings)

Example: Push + light + light - push again + light + Heavy (into repeating sequence) then restart that or adjust to your current situation of enemies and stamina)

I use the pistols explosion to disrupt the crowd aswell with its increased explosion size. Clip dump can easily take out a horde or at the very least reduce the numbers greatly (7 shots)

Specials/Elites:

I use the pistol for ragers and maulers, while mixing in melee.

Grenades are reserved for Crushers, Bulwarks if theres more than one, maulers and armoured ragers if it spawns a pack of them, then swap to pistol follow up.

Mutants after a doge I melee : light + Heavy (uppercut). 

Every other enem  is just melee or pistol. I only outlined the main troublesome enemies.

IMPORTANT: if you are out of grenades the pistol is strong enough to kill a crusher but will take 6 - 7 shots (clip holds 7) 

Boss:

You have to rely on grenades and pistol and sneak in melee attacks. You can do good damage but you do need your team to help ideally as i find the Veteran to be quite squishy.

Feel free to suggest some tweeks but this is my main build and it works well for me.

Note: dont expect a build to carry you, you still have to be good.
