After Reset™ RPG - a hard sci-fi role-playing open world game with old school top view, which action takes place in the future on Earth dying slowly after nuclear cataclysm that buried nearly all life on the planet.
Mutated Citizen – a person affected by one of the varieties of Biomass, for whom the infection has already passed from the incubation period to become irreversible. Because of the characteristic features of the infection, which cause mutations in the musculoskeletal system and the central nervous system, this being moves much slower than a normal human and frequently dies from lack of food. However, the main danger they pose is the possibility of their infecting other people, thereby provoking a real epidemic.

Looks good, a few variations of it would be cool, such as different colored clothes/skin. Not saying weird colored skin, just different tones to it to make them not all look exactly the same.
