Fight to protect the Earth from extraterrestrial life, or fight for coexistence.
About
In the year 20XX, Earth is plagued by numerous 'Kaiju'—giant extraterrestrial creatures ranging from 25 to 40 meters tall that have arrived and settled on the planet. The newly established 'Earth Defense Force' (EDF) developed 20-meter-class humanoid robotic weapons called 'Sentinels' to counter these monsters, gradually mass-producing and deploying them worldwide. A few years later, a Japanese military faction called 'Sanctuary' began secretly developing Sentinels and appearing on the front lines, advocating that 'Kaiju have lives too.' With the emergence of Sanctuary, the battlefield has descended into chaos. Can you survive this three-way struggle!?

Intro
In the year 20XX, humanity's cities were devastated by 'Kaiju' that suddenly descended from space. Humanity was helpless as the destruction spread across the globe... Subsequently, the 'Earth Defense Force' (EDF), established by Japan and other nations, developed 20-meter-class humanoid robots called 'Sentinels' to combat the Kaiju. However, an organization called 'Sanctuary'—which seeks to protect and coexist with the Kaiju—secretly developed their own Sentinels and appeared on the battlefield.
You are a regular soldier for either the 'Earth Defense Force' or 'Sanctuary.' Which side do you belong to, and how will you fight?
