Seriously, given how the boss battle is handled Kuzmann needs a nerf. He is too tanky to be shot down and come back up as we try to move his head to a termianal. I swear hes has more health than the campaign bosses considering how much ammo is needed to take him down once. Its not that Kuzmann is hard per se, but his fight drags on for so long and is an absolute chore to play.
Lower his health, make the body recover partial health instead of the whole bar, give him critical weakpoints or something. This level has to be one of the worst given how much of a slog it is to get through it
