Not sure about the food. I do know we have a life size open chested cadaver that we will be filling with a tin of pulled pork for people to eat out of.
As far as the game, this is my idea. I am open for suggestions though.
First - I am making a video with Professor Ford from my invite:
He will talk about the virus and the effects with flashes of zombie clips from movies.
He will them let everyone know that the virus has mutated and all guests have been infected. He is on the verge of finding an antidote but needs samples from 5 cadavers. Th cadavers have been dismembered and must be reassembled for samples to be taken.
We will give each guest a piece of a puzzle (or pieces). They have to assemble their puzzle and that will be there team. I figure 5 or 6 people per team. Then they have to find the body parts and reassemble the cadaver pictured in their puzzle. The body parts will be scattered all around our property and in our basement. The first team to assemble their body wins.
I have will also have made syringes filled with green jello shots, which will be the antidote administered before the guests leave.
