Overview:

Year 2145. The discovery of gravitonium allows humans to increase their physical and brain capacities tenfold, leading to a wave of intergalactic exploration that has led to colonies across the universe. In touch with new forms of life, the humans created "The Alliance," a special unit in charge of the regulation of resources and intergalactic conflicts. But the Saurian race, aliens dependent upon gravitonium, jeopardize the balance in the universe. When The Alliance's Espérance ship is attacked, two Alliance Space Agents are tasked to secure the ship. On board, the future of all mankind is at stake.
