Veteran Brawler (Revolver Ocelot)
 Veteran Build - Warhammer 40k: Darktide 

Weapons

Works great with any melee you like. This is a Brawler build, you will frontline when possible, use melee a lot. Target Specialists and other distant disruptive elements with the Revolver, then switch back to melee. If you want to run real fast, the Catachan Mk III Combat Blade is a great option.

Using Reload Speed as dump stat on the Zarona Mk IIa Quickdraw Stub Revolver, because switching between melee kills and ranged gives us an ammo reload due to Always Prepared.

Tactics

Shoot things you are too lazy to run up to!

Keep switching to the Revolver after melee kills, then back, to reload your drum!

Use Infiltrate to stay alive or hack terminals or pick up teammates!

Throw Krak Grenade at Elites and Monstrosities!

Talent options

Survivalist instead of Fire Team is a perfectly viable option.

One Motion instead of Longshot can trade some ranged damage bonus for faster swap between weapons.

Leave No One Behind instead of Demolition Team if you are less dependent on grenades is fine.

Shredder Frag Grenade instead of the Krak Grenade is a good option if you go with slower heavier melee weapon that is more Elite specialized. Clearing large hordes then consists of dropping a Frag in front of you and hold the enemy back with block/push.

Ability options

The Brawler is not dependent on any Ability, you are free to choose, but this is thematically not a support or a marksman build.

Executioner's Stance with Enhanced Target Priority can definitely be useful, in this case Competitive Urge could be given up for Counter-Fire or The Bigger they Are ....
