One advantage we have is most zombies are not very bright. If they see prey they reach for it. I regularly use this to my advantage. When underseige I present myself myself from a third story window and present them with Bunny FooFoo.

Bunny FooFoo is a five gallon pail into that I have some home made rebarb with one bar looping to provide a place to tie a rope or parachute cord. The system is filled with concrete and allowed to set.

Bombs away. Lil Bunny FooFoo falls two to tree floors and impacts the zombie. Pull it back up manually or with pullies or a winch. Rinse. Repeat
