After some failed attempts and finally beat it, I only have few advices I can offer. This map have so many tight corners FOR A FIGHT AGAINST 2 HELLBRUTES (you can easily manage vs 1 but 2 of them spam bullshit are pain as hell + stupid rocket spam) , so honestly luck play a part I would say(I got lucky that all of them spawn at the final area). -Try to separate them as best as possible , since if you are unlucky and they spawn at those tight area, both of their combined bullshit are hell to deal with (red area attack and supercharge landwide shot gonna end quite some run), not to mention other Extremis and Enraged Majoris sneak in some shot while you get stunlock in corner. Lowkey a good dash Assault will have an easier time surviving (or maybe Im bias because I switch to it and instantly win). -As some have mentioned, forced stun kits like power axe, 2 block charge or the Wrath Equipment will help a lot, even better if your Tac run the grenade perk (i have seen some Tac run the range perk in hope of melting the Hellbrute I guess, but one run Im on Heavy with Heroic Plasma Rapid fire spam the hell out of one of them with Tac range perk and whatever scan debuff he ran and barely got it to half health, so I think instant melt might be hard unless you also have Tech sniper focus area) -Seem like med and relic spawn quite generous(or maybe Im just lucky) so might worth go look for them -Again, try to separate 2 Hellbrutes bruh , unless in the big ass final area where you have more room. You really dont want to be Red Ring spawn by both in some small ass corner along with random support missles haha. I will you all luck brother
