Forceful Dog Tank
 Arbites Build - Warhammer 40k: Darktide 

Detain the lex breakers, stop, drop and stop resisting! The beatings will continue until morale improves!

This build comes with all the possible crowd control tools a tank could have, let me count the ways:

1. Break the Line the big bada boom of everybody goes on the floor. Have fun charging into elite packs, all the time.
2. Branx Mk VI Shock Maul and Suppression Shield special flash, big aoe makes spiky people blink for a while. Constantly available, use it often. Especially great when moving into gunners (you are in blocking status while using the flash), while blocking their shots, but will also make melee elites pause.
3. Dog pounce to disable any non-monster enemy, humans it just eats, Voltaic Mandibles Augment makes ogryns do a jiggy dance.
4. Remote Detonation dogsplotion, makes a whole elite pack stutter and gives monsters a pause.
5. Lethal Proximity pull out the gun for a quick close up stagger if need be, also improves the dogsplotion range.

Or you can just beat them up with your trusty Branx Mk VI Shock Maul and Suppression Shield , improved push of a shield weapon, the H1 shield bash has excellent aoe stagger to smash groups of enemies and stagger elites and the basic light combo is enough to put Maulers and Ragers on their knees while doing great single target damage. H1 > H2 > L3 > L4 for the highest stagger combo, which is enough to disable any elite (except Bulwarks, for those use options 1-4 before commencing with the beatings.).
