In order to get badge, dont buy the upgrades before the TV's. Wait until you have bought every single upgrade, then save up to buy them all in one go. Worked for me.
folks we got a rare treat today. Coming out of Mexico, its double jointed BLACK MASK GUY! And in the other corner we have the reigning champion of the world, double jointed BLUE MASK GUY! LETS GET READY TO RUMBLEEEEEEEEEEEEEEEEEE!
wow what are you guys talking about the zombie badge, its easy, just beat it on first try with the shotgun, btw im playing on a laptop with no mouse so it was harder for me
loved the game, first played it on newgrounds and became addicted, now im playing it here again, my top score is 11165 hop i can beat it soon. :) I give it a 10/5 for being so addicting. I would gladly play this game again, even without badges.
