"Behold, we are the Arms of God, to do his will upon the earth. For the Lord God comes with might, and his arms rule for him" - this creed is both your driving force and your burden. Hellish demons have overrun the world, and the Order of the "Arms of God" was meant to reign over them, but it has been decimated.

You stand as humanity’s final beacon of hope, charged with resurrecting the Order and restoring divine order to the earth. As you face legions of fiends, you gain strength, able to sanctify your weapons and wield your mechanical arms in the execution of God's will.

In your relentless crusade against the infernal waves, you reclaim sacred grounds, drawing closer to the throne of damnation, where the greatest evil seeks unlimited power to enact its darkest intentions. Your sacred mission is to forge a weapon so mighty that it will smite the heretics and endure the trials against the most fearsome foes.
