I am going to make this short.
As a fan of 1968 Night of the Living Dead, I implore you to add a feature
called 'Fear of Fire' to sandbox.
It will make zombies be afraid of fire, just like in NOTLD, here is a scene to demonstrate

It would be RADICOOL if you could also add in a gas pouring feature so you could make a ring of fire with matches and a gas can as well
