Iro Hero

By the year 2306, humanity had learned to harness its own bioelectrical energy to produce electricity—a gift that was quickly turned into an instrument of control. Corporations found that humans themselves could be maintained as batteries, and the industry built around this discovery reduced most of the population to fuel. When his mother dies, a teenager named Iro learns that he may be the anomaly the system can't contain: the key to breaking the hold that the energy industry has over the human race. Iro Hero is a vertical shoot-'em-up with a story built around Iro's gradual understanding of his own role in a system designed to keep everyone powerless.
