My buddy and I developed the most fun thing we have ever done at a party. It is best to do with 2-3 people. Everyone at the party is a "walker (zombie)" and you have to blend in. You can talk (minimal), acknowledge someone BUT you can not stay in one spot to long or let a group of servants (females) nest around you. You're still in cover if its only one or two, but getting a large group blows your cover and then you have to shotgun a beer if revealed. You can make own variations to rule, but just be careful of the walkers . It all started with the notion to find the perfect ass among the 'walkers'
