A FINE RED MIST [H40 PBB]
 Ogryn Build - Warhammer 40k: Darktide 

This build is an absolute blast and a great alternative to the PBB Rumbler Ogrynheimer build or the PBB Twink build. It packs as much of the damage as either of those two builds and is a ton of fun to play. There is nothing like getting multiple lucky bullets from Burst Limiter Override while shooting the Kickback and seeing everything get absolutely annihilated! Just make sure you're bracing the gun because it kicks like a mule when you get multiple lucky bullet procs (also you get toughness from Steady Grip and some damage reduction from Mobile Emplacement). 

I've tried to get as much damage out of the kickback by giving it very fast reloads with Pacemaker and Keep Shooting and helping its problems with armor by taking Dominate (although even crushers get knocked on their asses by a kickback shot to the chest). 

The Kickback currently has a broken blessing that doesnt quite do what it says. Pierce is supposed to apply the extra cleave and stagger to the special attack which would normally make this a useless blessing. But it was recently discovered that it actually applies to the actual shots themselves also. This lets you absolutely annihilate entire hordes very quickly. We take advantage of this by using Light 'em Up to spread burns like crazy. Add Blaze Away to round out the blessings for a big boost in strength while firing continuosly and you are going to be doing massive damage. 

The Powermaul is there as a nice "get off me" tool that. Use the special in between Point-Blank Barrage CDs to get enemies off of you in a pinch. You don't need to be too stingy with the bullets on the kickback because it has very generous ammo cache for you to dip into. 

Feel free to take whatever blitz you like but I tend to take the frag because you can deal with muties and other specialists with your gun quite easily.
