Be immersed in thrilling audio fidelity to the myriad gunfire, explosions and pulsating sound effects as you race across the battlefield!

Smartly use IRCM to evade the constant barrage of bullets and missiles.

War! Intrigue! Nations and Mega Corporations vie for control over an ancient weapon discovered in the near future.

You must pilot the mecha “Gigas” and survive against endless waves of enemies in order to achieve victory.

Synopsis

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.
