 Veteran Build - Warhammer 40k: Darktide 

This is a high(er) skill floor build to capitalize on breakpoints you can reach on knife with Vet. Push attack spam is your best single target dps and is sustainable (but not always safe!) thanks to the 2x0.25s stamina regen reduction talents. Serrated Blade lets us take Mercy Killer. Mk6's horde combo is L1H2. Most enemies will die in 1 or 2 pushstab headshots. Crushers and Maulers in 3 - they can die in 2 if you're lucky with crits.

Zoom around and dodge and slide to keep your stamina and crit rate up.
 

With this build, recon lasguns have good dps (even against armor, thanks to Rending Strikes and Onslaught ) and good ammo economy (helped by Infernus and Shock Trooper ). VIc is the best balance of damage and ammo.

You should have 2-3 toughness curios to improve survivability helped by Iron Will and Confirmed Kill .

Poxbursters, or the mutants that bring you to them, will be your number one danger. It won't be crusher/mauler packs or large rooms filled with shooters - you're built for those.

Use Infiltrate to regain your toughness and reposition. Holding block as you go invis is a good habit. Stealth is also great for objectives - pop it before you pick up batteries or start a hack.

Smoke grenades are underrated and taken to save talents for elsewhere. Throw them down on your team when you're surrounded by shooters. Dogs also apparently have a hard time finding targets in smoke?
 

Keystones aren't terribly helpful with this build. You only get so much out of Focus Target when there's 20 taggable targets on screen at once and Onslaught already helps your team's damage. Marksman's Focus would be better suited for a gun with a higher finesse multiplier. Weapons Specialist gives limited benefits - ranged crit chance only benefits single shots on a high firerate weapon, crit chaining aside, and the melee attack speed buff doesn't help pushstabs and Fatshark's servers like to bug out on high attack speed weapons anyway.
