Shooting the boss is easy, as can be seen in my old runs. Go to sniper mode, point the left lower tip of the crosshair at the boss, then shoot. (In case you didn't know, there's a version of MDK that permits you to save anytime, it's easier to practice that way.)
The gog version permit to save. I know it easy, I done it in training at 80% (other time it's on the little ball around for one or two shot).
But in SS I succed at 10% because it's when I started to be tired in fact. hard to focus all the time after 30 min of one run and 2 or 3 false start before XD
