In the early 21st century, Earth has reached extraordinary heights of technological progress — and paid for it with environmental damage beyond anything previously imagined. Then disaster strikes: a massive floating fortress appears in Earth's orbit and a force calling itself the Beast Empire begins invading the planet. An entire continent is destroyed. With humanity on the verge of extinction, a special unit enhanced with the latest bio- and technological breakthroughs is deployed. Young soldier Abel leads a group into the field to investigate a site where a previously sent team has vanished without a trace.
