I don't know much about Equilibrium... maybe I'll try to conquer it again in the summer. But I don't think they've reduced the difficulty. That's how they'll get the money... with such a horde! What else can they do? Robbing various crypts - of course.
Regarding resistance, I meant the hero :) He may be a lone wolf (in that sense), but I perceive him as a unit... because he only kicks or shoots.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
