At one point I was looking at doing something similar with a zombie game that would involve physical movement--scouting, carrying messages, etc, similar to Zombies Run but with a community aspect and the ability for a game master to inject new elements. ("R&D just figured out how to boost transmitter power. Here are the parts your community needs to scavenge or trade to do it." "Work together! We need help moving these packages of virus samples across the country.")
