Doomguy Vet
 Veteran Build - Warhammer 40k: Darktide 

This is my Doomguy Vet build:

Weapons

     Alright so the Chainsword is kinda mid right now, which is a shame because it's one of the weapons that I started with. But it's hard to succeed with and it's gonna stall you from pushing up into higher difficulties.

     The Chainaxe, however, is pretty decent if you can get around its weaknesses. Namely: it either sucks at dealing with hordes, or sucks at dealing with Crushers. And even then it's not incredible vs. Crushers but we can get it to take them in a 3-hit combo (Heavy Weapon special, two lights and they'll bleed out). Take the Mk IV, not the Mk XII because the Mk IV lets you just light attack into Ragers and end their whole career in 2-3 hits while stunlocking them. Use heavies into hordes.

     Speaking of hordes, because we're not taking something like Slaughterer, we're gonna be kinda mid at dealing with them. Hence the Super Shotgun. Get a couple melee kills to guarantee a crit on it from Weapons Specialist, and fire one shot to delete the whole horde and whatever elites are mixed in with it. Man-Stopper is gonna let us cleave through the whole thing. Only really need to use double barrel if you've got like a 12-stack of ragers or 3+ Maulers. This will 1-shot Maulers but you gotta be pretty close and aim for the chest. You can finish them off with light spam or use the Heavy Special if you didn't hit em with the shotty.

Talents

     We're taking Voice of Command because it's the best Vet ult and the most Doomguy-coded. We're taking kind of an off-meta build so I wouldn't recommend skipping the "Press F to Win" ult. Just remember that even though you CAN use it to get a res in, doesn't mean you shouldn't be throwing that out at the start of combat to prevent your team from going down in the first place. It'll usually be off cooldown by the time someone goes down, don't be that guy.

     Grenades are to-taste. Strictly speaking, the build would be vastly improved with Smokes. But they're not Doom-ey enough for me so I go Shredder Frags for the hard CC. You can also pitch em at a gunners nest in a pinch. If you do take Smokes, drop Grenade tinkerer and pick up any node you'd like (Confirmed Kill, Superiority Complex, Skirmisher, etc.)

Build Weaknesses

     We suck, and I mean SUCK at dealing with ranged threats. You're going to have to rely on positioning and your teammates to deal with gunners & snipers. Every now and then you can blast both barrels and pick off a sniper at range, but don't count on it. You will be able to suppress them with the shotgun, but it can be rough if you're in that room with 50 gunners lined up on you. If your team can't cover you, you'll have to close distance and engage as the God-Emperor intended. I tend to throw grenades in these situations to buy some time. Also, build can be a teensy bit ammo hungry. Not too bad, we're Vet, but just try to balance out how much ammo you're using.

Good luck, have fun, purge spikey ones!
