Killing Red Guys --> Throw them to air let them open their metal wings, when they open them, grab them and throw them to ground
Killing Blue Guys --> again throw them to air and let them open their parachute, then click on their parachute to tear it down, they will become as a normal villager and you can simply throw them again to air inorder to kill
jetpack guys--> try to keep them in the middle till they got out of fuel, then you can send them in air for their last fly...
this game is hard for a sure, so its ok to abuse bugs :d here is one that might be usefull to you, this works with shotgun as i see didnt tryed on all weapons. "" Hit the damn zombies with shotgun and while you are reloading, press Escape button to pause the game, you will still continue to reload your shotgun while the zombies freezes on their place" this is very usefull
is this game bugged or something? after sun rise where is says there is only 1 more difference, i used my Hint with "H" but it still says there is 1 more.... and clicking on a house near the edge of screen makes it flash but its not ending i clicked on every pixel still not working
