I'm trying to unlock all powers but I didn't unlock some powers on my good game before I finished and now I'm playing it afterwards but I rarely see enemies so I play the generated content. I'm only missing the good karma rockets and the last grenade power. The rockets I can't unlock without doing the hit flying enemy stunt which appearently I didn't do enough while fighting the ice guys. The grenades I think are glitched, I did the stunt needed for it enough times but it's still locked despite saying I did it 11/11 times. I'm playing my evil game right now and saved a second file before choosing between Nix and Kuo so I can always start from there as a good character but I'd rather not.
