The Inspector - Castigator Detective Build
 Arbites Build - Warhammer 40k: Darktide 

Well rounded Detective Hound build - "I see he's fighting 'til the end, That's what I call a good friend"

• Arbites Maul -  Your Old Riot maul before you became detective and kept for "sentimental reasons". Great for mixed hordes using the push attack into wide cleave heavy swings, perfect with Drive them Back and Weight of the Lex. Proc High Voltage easily with the weapons special well as your bois Voltaic Mandibles Augment.
• The Zarona Revolver - The detective special. Great for gunners and even armor thanks to Crucian Roulette , only 2 or 3 shots are necessary most time into crushers with with Efficient Killer and Zealous Dedication helping out. Quick reloads also with Judicious Efficiency and Priority Endowment turning this into a real 6-shooter. 
• Lightning dog - or Kommisar Rex to his friends, is great to disrupt and to deal with ranged foes when low on bullets. He doesn't need a warrant to bite first with solid Boss damage between the dog and your revolver thanks to Keeping Protocol and Monstrosity Hunter. Chaos Spawn's are just big meatball who thought they could outrun a good boi.
• Castigators Stance -  A solid defensive ability in rough situations. Every episode's got that moment where the partner's cornered before Rex comes crashing through the door, this is that button.
