Some others and I thought of one in Mexico city but with a twist crossover with Plague Z

Survivors are in a city surrounded by walls some 20 odd years after the apocalypse, but then part of the wall exploded and crumbled, allowing whatever is out there to pour in. The players would control a character and are allowed to form gangs and other stuff and interact with factions throughout the city. Resources centers, like marketplaces, would be a factor as well.

Events would be given via Radio format
