The aliens came with the giant monsters and robots that had ensured their previous conquests across the galaxy. But their latest prize was far from defenseless, and Earth’s own giant monsters and robots joined forces to engage their foes in a terrible war that has devastated the planet. When the aliens requested peace negotiations, Earth’s nations reluctantly saw the need to cease hostilities while there was still something left of Earth to salvage. The only participants in the war with any direct experience with one another have thus been assigned to come together in a desperate attempt to negotiate a lasting armistice.
