It has been fifty years since humanity first moved into space in large numbers, and the tensions between people born on Earth and people born in the colonies have finally reached a breaking point. When the Federal force deploys a giant laser weapon with the clear intention of using it against the colonies, a small group secretly develops the GEMINI ARMS: a system that lets pilots switch between a high-speed fighter and a powerful robot mid-battle. The colonies' only chance is what this small team built when no one was supposed to be watching. A retro-styled shoot-em-up about fighting a war that the powerful thought was already won.
