Synopsis

In 2050, humanity has made serious strides in space technology. That changes when the Eldar suddenly attack—a civilization sent back 250 years from the year 2300. In their time, Earth invaded their planet and crushed them using Trinity Energy, a weapon far more powerful than any hydrogen bomb. The Eldar's plan is straightforward: travel to the past and steal Trinity Energy before humanity can use it against them. They start by seizing Io, one of Jupiter's moons where humans have established colonies. From there, the Eldar launch a full assault on Trinity City with waves of creatures called Cosmosauruses, determined to claim the Trinity Energy. Toshiya and his friends pilot God Sigma to defend the planet, kicking off a lengthy conflict to reclaim Io and stop the Eldar invasion.
