 Arbites Build - Warhammer 40k: Darktide 

Dive gunners, leave the backline behind, you are your own backline (note: given the amount of buffs proc'd on elite kill you need to play/dive into elite packs as much and as often as possible so it is often a good idea to be generally pushing and outside of coherency from you team).

Save nades for staggering reapers/gunner packs for diving into melee otherwise you will get shredded (elite ball knowledge: if you have a horde between you and the gunner line use it to proc tdr buffs/toughness replenishment so you can safely dive the gunner pack)(horde is a toughness replenishment resource that needs to be shared by the whole team, horde clear as a team role is literally throwing in the face of H40 gunners and only continues to exist since the psyker cabal keeps pushing propaganda that they are needed to win, while fucking over the entire team enough to require zealot book or shout vet to upkeep toughness).

Save your ranged for specials as much as you can, you won't have the ammo econ to sit back and shoot everything that moves or even just the gunners (plus the reload takes long enough to be inconvenient.

Further elite ball knowledge: for revives make sure you have your shot pistol and shield out, it has a stupid amount of innate block cost reduction; elitist ball knowledge: you can perfect block an overhead with a revive if you time it right.

Anyways, dive everything, kill specials and elites, keep hitting break the line (if I hear one more brain dead comment saying that break the line is smite but for arby I will lose my shit, especially when shock mines exist and turn the game off more significantly).
