So I'm wondering how well it would work to combine a hidden movement game and a zombie game. The premise is that there is a carrier of a virus that turns people into zombies but the carrier themself is immune to the virus. One player would be the carrier of the virus traveling through a city out of sight of the other players. They would control zombie spanning and movement. The other players would act as a taskforce team trying to track down this person while dealing with the zombies that are popping up.
I'm not so sure this would be my style of game but I think it could be an interesting take on the plethera of zombie games out there.
Oh there's a plethora of convenient reasons why the zombies don't eat the carrier. How about either the zombies see the carrier as another zombie because of the virus or it takes some time for the virus to take hold and zombify someone and by that time the carrier has left the scene.
