You're supposed to shoot the last boss when his purple smoke is coming out of his face. I can't dodge for toffee, I've tried pressing up on the stick or down+B, it works when it feels like it.
No no...I got that straight away...that bit is pretty self explanatory!
Basically I kept getting up to the final section of the fight and when he was doing the running charge I was getting totally screwed over with it haha! Was so frustrating as I coasted the first 2 transformations...seems I should have kept a rocket launcher Would have solved any issues haha!
I was just flicking Up on the Circle Pad and that worked nicely, as long as you weren't moving it seemed to work out!
