Battle Protocol

In the distant future, humanity abandoned a devastated Earth and migrated to Mars. After many years, signs begin to emerge that Earth’s environment has recovered. Hopeful for restoration, the Earth Federation on Mars prepares to return and rebuild their original home. A reconnaissance team is deployed to survey the planet and assess reconstruction viability. However, they soon discover that Earth is no longer empty. Savage, unknown lifeforms have claimed the planet as their own — and they violently attack any human presence. In response to the escalating threat, the Earth Federation dispatches its elite combat operative, 'Yang Soyoon', to confront the monstrous beings and reclaim Earth. The mission to retake humanity’s birthplace has begun.
