TECH OVERGROWTH - Early Concept Design.
In the near future, a biotechnology and energy company called Frameshift Corporation changes the world. They bioengineer a life form whose blood can be used as a power source. It is many times more efficient than any other energy source in existence. Within five years, ninety-nine percent of households run on Framefuel, the branded biofuel created by Frameshift. In-home power cells, branded Framecells, contain live genetically engineered life forms, their blood continuously harvested to provide power to the home.
The small Framecell, seen here, is found primarily in residential areas. It is able to provide power to a typical household, with Framefuel to spare in the integrated portable cell. Post-apocalypse, the Leaper creatures are incubated within these Framecells. Once born, they lurk nearby, seeking out human victims to impale and dismember.
