590,190 on my third try, some tips : the purple are by far the most annoying i used my Berserk on big groups of them, i stayed to the right side and strafed up and down to cover the entire screen with bullets, use slow time in short bursts, holding it down for a long time will mean it will be down when you really need it. If you get frustrated because you can't get the hard badge, take a 5 min break and try again. GL =D
