Gigantes Ex Machina

In a future world devastated by endless wars between nations and megacorporations, humanity, driven by escalating arms races, excavates the ancient weapon “Gaia” long buried beneath the earth. What they uncover, however, turns out to be a catastrophe incarnate. Facing extinction, nations and corporations form a temporary alliance to resist Gaia. Decades later, the player awakens as an experimental candidate for “Anima,” a pilot of the next-generation weapon system known as Gigas, and takes their first step into this age of chaos.(Storyline via IGDB)
