on the kongregate chalenge use 3 damage buffers and one heavy, max they out, and you will kill every enemy with one shot (even Kongregate ship!), you just have to hit they :D
the hard one was easier than the others O.o, I used 1 dual, 1 heavy, 2 damage buffers and 1 health buffer, on the last enemy, i used the dual to kill the small ones and the heavy to kill the boss, doing 63 damage each shot.
