The Professional Mad Lad
 Hive Scum Build - Warhammer 40k: Darktide 

So going to keep this short because honestly the build isn't complex. Basically take the shivs and stab, that needle gun? That is just for a quick 3 tap into anything tanky like say a ogyrn or hit a special 1-2 times and move on so the poison can kill it. Melee is your friend here if you try to do range with this build you will die. Between the bleeding, the poisons, and crits you should be able to shred single targets. Because of the speed it isn't bad at just removing hordes too. Adrenaline Frenzy works well with this because of the speed your attacks you don't have to worry about aiming at heads in the mix of things and you generally want to be able to keep building stacks when the game decides you are fighting a boss now. You can drop your box Stimm Supply any time there is a horde, your friends are close, or if you just need some room to pick some one up as the boost will help you clear a bit before the poison creates some room. Throw in the poison nades Chem Grenade  if you need to make a lot of room really quickly as it's huge radius and chain explosions means you can deny an area when you need it from the horde. Testing this out in the meat grinder I have found you can down the 3 ogyrns in about 3-5 shots with 5 being the high end of Bulwark. You don't even need to pen armor just don't shoot the slab's shield and let your ticks drop them. Targeted Toxin allows you to reduce the incoming so the few times you eat an attack for what ever reason it isn't as bad. Keep in mind you aren't a tank you are melee dps. You are a blender and you can quickly dispatch a ton of things in melee. Your Pew pew Branx MkVI Needle Pistol should be treated as a "they are way over there and I can't be asked" or "That guy is very large" .


TL;DR: Run into melee stab everything in the face and dodge out of the way of things that want to stab you in the face
