Im going to repost some very helpful tips for the hard badge(all credit goes to VonAwesome):
If you're struggling on the Hard Badge (2 Slice) Here are the levels you can make the biggest gains over the "Gold %" (To get to that 1875) Level 4: Shoot for 70-75% (Get lucky, have a high block knock a low block down) Level 7: Shoot for 70% (Cut the white and red at the same time first) Level 12: Shoot at 95-100% (Drop a triangle of white from above, and cut the red into two un-even halves. one half is levered into the hole, the other is pushed off the edge) Level 14: Shoot for 80% (cut from bottom left peg to above mid-right peg. cut from just below mid left peg to top right peg. A parallelogram will slide loose, and the triangle above it should fall and just barely make it out)
at first i was kinda skeptical about the game..but after figuring out the michanics and giving it a shot..i really like it!!!dont listen to haters...keep the good work up!
death duck sucks but for the last level it was actually quest useful...i also used energy homers ans slow time to beat the last boss....most of the game i was using lightning(the best weapon in the game) along with the shield shooting one and bfg or big lazer...
i barely got the to wave 15 in survival mode with the golden commando..30 points x2 is more than enough for me ..goodbye wonderful concept went bad.............
