Hive Scum Anti-Ranged Support
 Hive Scum Build - Warhammer 40k: Darktide 

Simple idea to this build is to slip and slide to survive, focusing all attention onto range threats in the elite classification.
This build will have you slipping and sliding all the time with pistols drawn focusing your attacks onto gunners, heavy gunners and sniper mobs

With pickpocket you should always have ammo available and with extended clip from ammo jack your ranged uptime should be 99%

Stimlab set for attack speed and stun/slowdown immunity with some Toughness regen (40%) and a little damage reduction. (8%) keeping the re-use timer down to 51s.

Blessed stims should keep your corruption in check

Boom bringer to delete boss mobs

Anarchist for additional damage, (advised) but gunslinger could be useful for the group in your support role, Higher difficulty games will suffer without this damage boost as everything matters in havoc and auric.

Gunners and heavy gunners are your worst nightmare in open spaces at range, damage reduction is in the curios to mitigate any "issues" Otherwise curio configuration is somewhat standard.

Ranged Blessings Run and gun + sustained fire to grant additional damage when attempting to pop highlighted targets at range, with additional damage to elites and flack enemy's this should not be an issue removing them from the field. thus doing its job cleanly.

Shivs set up for trash cleaning, not to be relied on as a serious option but will do fine for basic garbage disposal.

Summary, fast moving ranged strictly, anti ranged and elite mob build that can stand on its own by slipping and sliding around between dodges and slides. Fun to play, can take some time to get used to if you are a slower paced player.

Enjoy
