By the year 2050, mankind begins the colonization of multiple solar systems in search for habitable planets. However, while the colonists establish original cultures and scientific studies, many of them began feuding with each other and battles broke out among them and the Earth. One rebel faction in particular rose to great power and made Earth their primary target. Earth's response was Operation Viper Phase 1: to combat the rebels using advanced space fighters built from downed enemy ships.
