On level 5. Go near the end and the the bullets shoot the light box thingy. then keep on a low altitude and get the last star on the left bottom corner. Have fun getting the badge :)
lolol this update sucks 1/5. Nah, just joking. I haven't played this game for like a month or two, and i see what you've done thar; Also, I got a suggestion of the battle arena. Can you make your guy move? It's quite boring to see your guy getting hit by a walking dummy(yeah i'm a noob)
