Astro is an action game developed by 7 Raven Studios Co. Ltd. and released on Nintendo 3DS.
At the dawn of the 30th century, the invention of the tachyon-reactor saw the beginning of the space age. With small quantities of "Star Platinum," a mineral found in the asteroid belts, the tachyon-reactor could produce an immense amount of clean energy. This maintained interplanetary travel and the gigantic oxygen-generators required by the colonies. Human colonies appeared on all the 9 planets of the solar system.
