Living After Midknife - Plasma Til The Dawn
 Veteran Build - Warhammer 40k: Darktide 

Stars of the show are the quick swap speed on the Plasma Gun and the Mercy Killer blessing on the Mk6 Combat Knife - the Mk6 has sweeping heavy attacks to get Weapon Specialist kill procs to turbo charge the Plasma Gun compared to the Mk3.  When in doubt vs an Ogryn target, charge a Plasma shot and swap to knife for the finisher.  Swap between ranged and melee as needed.  Mk3 knife is better with a bleed or single target blessing (Flesh Tearer and Precognition keeps winning) to set up Mercy Killer weak spot hits instead of Haymaker due to single target focus.  Haymaker is great for general use on Mk 6 knife with Mercy Killer if you don't mind weirdness on not doing kill procs.  High toughness regeneration allows for frontline play - Stealth is an emergency regeneration and suppression button.  Smoke grenades work better after Patch 17 to break line of sight on gunner clusters and are game winners for closing ranks - no need for grenade regen due to 5% grenade on elite kill talent.  Infiltrate tops you off in tough times and leads to clutch revives. Plasma stats are a free space - most of the time the build is either swapping for a fast light shot on guaranteed crit after 3 melee kills or lining up the world's beefiest heavy charged shot after the crit threshold.  Build works great with Revolver with Hand Cannon and Crucian Roulette too.
