I'm sorry but, those lawn mower things that replace the burners, are just useless. It doesn't even matter if it helps me get more perfects, y'know why? I CAN'T SEE WHERE THE ZOMBIES ARE STANDING! TOO MUCH BLOOD IN THE WAY. I prefer the burners, I do MUCH better with them. Other than that one flaw, the game was great! I love games like these, also very original combination of ideas.
