Peak London Experience: Crackhead Simulator
 Hive Scum Build - Warhammer 40k: Darktide 

Forget playing tactically, taking cover, or preserving ammo. You are a Crackfiend on a five-day stimm bender in the underbelly of Tertium. Your only goals are pure chemical dependency, maximum Carnage and introducing every heretic within a five-meter radius to the business end of a rusty shank.

If your screen isn't throbbing, and flashing warning signs, you're playing sober. And we don't do sober.

The Playstyle Guide

1. Pop your Cartel Special on cooldown to keep those 3 stacks of Chem Dependency active 24/7. 
2. When a horde rolls in, drop all pretense of sanity. Spam light attacks with your Mk I Shivs until everything stops moving. When a carapace target steps up, swap to heavy-attack weakspot stabs. Use Rampage when your getting swarmed by Specials and Elites.
3. The Revolver is fairely accurate and can deal with pretty much any threat. Fan the Hammer into anything that can pose a threat from the distance.
4. When a terrifying wall of specials like Bulwarks and Crushers blocks your path, whip out the bazooka, and watch them completely disintegrate.

I created this build to have casual fun in Auric missions, but I had actual success in Havoc 40s too.

For Havoc you might want to swap your curios for Ally Revive speed, but you can do whatever you're comfortable with.
