Boomy Kal
 Ogryn Build - Warhammer 40k: Darktide 

light melee attacks solve everything, from hordes, to ragers, mutants, elites etc. thanks to Thunderous blessing giving 20% bittleness together with 5% rending from tree.

use your ability to charge to gunner backlines and kill them with boop stick. the charge bleed stacks is enough to kill all horde groaners in your path, and what is left alive and bleeding gives you up to 60% damage reduction.

as long as you always stay in coherency and are always swinging your boop stick to regen toughness, you will be practically immortal. the only way you can die is when you stop swinging or when you have 0 coherency.

only use heavy swings to kill lone targets, otherwise just light swing gleefully when 2+ targets.

Frag Bomb can wipe out an entire room of crushers/bulwarks thanks to Big Boom+Heavyweight (ogryn's signature racist talent).

against less than 4 crushers, swap to rumbler and fire directly at them. takes 2-3 shots to kill 1 crusher. dont fire directly into bulwark shield, bait his melee attack, dodge backwards and fire into his flesh when he is exposed.

note that each small ammo pickup gives you 4 rumbler grenades, don't overtake ammo.

rumbler with shattering impact and adhesive charge is the highest boss dps in the game barring the meme hammerzealot. as long as your grenades stick to them.

thanks to Bruiser talent, as long as you are staying in coherency, your ability can come off cooldown once every 10-15 seconds, be sure to spam it to get to enemy backlines, downed teammates etc.

ogryn cannot be stunned by melee nor ranged attacks, and boop stick is capable of staggering ragers even during their normally unstoppable melee combo. bonus points that your boop stick's special attack (the slap) is capable of stunlocking bosses if you can reliably slap their face.

as ogryn you should always be the team reviver, and the hacker (lol) since you cannot be stunned at all.

ogryns are very subsceptible to dog pounces due to his size, which is why Pained Outburst is amazing. with Pained Outburst, ogryn is the only class able to get a dog off him the moment his toughness reaches 0.

alternative melee:

Bull Butcher mk. 3 with Confident Strike + Slaughterer for better horde damage, but less CC and little to no armor penetration.

alternative ranged:

Gorgonum Twin-linked Stubber with Overwhelming Fire/Deathspitter.

Kickback with Surgical/Full Bore.

Mk 2 Ripper Gun with Blaze Away/Can Opener (be sure to stab a crusher once with your ranged weapon special to remove his armor before unloading into him).
