What you do in level 67 is first, contact smithy to get 100 balloons and weaken the spikes that drop on you next to the hideout (you get the 900 dollars for it in the hidden crack in the wall in level 48 that contains $899.99, when you were not looking, the guy threw away all his money except one cent) Once the spikes are mostly rubber, you can get to the hideout, you see 100 dead guys and your guy tries to run, just click the other hidden crack in front of the exit that locks the exit, so your guy goes on, you find the boss and the is also dead, but he is a super awesome zombie now, so you have to contact your friend and he will make 20 shotguns smash into the ceiling and land behind you so you can defeat the boss, but it will only work when you picked up the aimbot hax in level 57 because he dodges all of your headshots unless you are using the hax, so all you have to do is click a bunch to win.
@LaBaDa well, don't leave hateful comments like that, after all, this is probably just a movement test. also. You should try to make a game. Because this probably already took an hour, so think how much effort and time it takes to make a great game.
