Dystopia Rising

"Dystopia Rising is a game world that takes place generations after the Fall of humanity. It's a world that focuses on the stories of rebuilding communities, the action and horror of surviving in a nightmarish wasteland, and the drama and passions of what it means to be alive. Dystopia Rising is not a game that follows hard science or facts; without question, it weaves pseudoscience and horror-fantasy aspects of the postapocalyptic and survival horror genres together to focus on the experience instead of being limited by the definitions of hard science."

the Infection
"In the Dystopia Rising universe, everything has Infection within them. This fungal infection gives all living things the amazing ability to regenerate. This means that when a person dies, what is left of their body will sink into the ground. This body will then knit back together, and they will be thrust back into the world. However, each person only has a certain amount of Infection. This means that after they lose their last Infection, there is not enough left of them to come back and they instead enter the world as a Zombie.

Lineage
"Within the world of Dystopia Rising, people have evolved into something called Lineages. These Lineages all possess different types of the Infection, which give them different traits. These Lineages, in turn, branch into three different Strains that each are slightly different."
