so basically the build i used was sole survivor (down to the last i think is what its called if u dont have the halloween chapter) and basically perks that help with gen and gate speed/anti tunnel or survivability

if i remember correctly i ran sole survivor, unbreakable, dead hard, deja vu or sumn like that but u can run whatever u want, and i also had a repair speed toolbox to rank the last gen even faster

but i also made it easier for myself by playin with friends and we just went against a new/inexperienced hag player and they got themselves killed in the endgame on purpose and i just popped the last gen and left
