Eve vs. Eidos 9 Corruptor, NG Hard Mode

Whose bright idea was it to make a boss fight just extra cancer? I just wanted it to be over, at least until I killed the dozer, and then the fight was fun because I could unleash my rage. This is the 3rd corruptor players can face, so once you kill his friend he doesn't put up a fight, even. As much as possible, keep both of them in your frame at the same time. And may God have mercy on your soul.
