Darius Twin
Darius Twin is a shoot 'em up video game that appeared in 1991 for the Super NES. It was the first new installment in the Darius series not developed for arcades, and also the first to have a normal 4:3 screen ratio. Interestingly, although it is a unique game in the Darius series, it seems to reuse sprites and background designs from Darius and Darius II. Even though the names of the bosses are new, they are mostly revisions of previous bosses.
Story
Many millennia ago, the young, peaceful world of Darius was invaded by an ethnic group of barbarians under the command of the galactic tyrant Belser. The peace-loving Dariusites were ill-prepared for such an invasion and most fell quickly. However, before the entire planet succumbed to Belser's rule, a brave young couple, Proco and Tiat, resisted and managed to escape with many other Dariusites to sectors of space that were still free. Over the centuries, the descendants of this resistance movement multiplied and populated many worlds. On Orga, a world with unusual resources, they established the command center of the Galactic Federation, a governmental organization that united all the peaceful worlds of the galaxy. After a thousand years, the Belsians once again decided to expand their empire and set out into space to conquer the people who had escaped them centuries before. The Belsians continued to expand and took control of even more planets in the solar system. Inspired by the legends of Proco and Tiat, two of the Federation's finest pilots now prepare their starships for the long galactic battle that awaits them. These ships, advanced technological marvels called Silver Hawks, are capable of converting energy into powerful weapons and armor. Your task is to pilot a Silver Hawk, defeat Belser's forces on each of the planets along the route you choose, reach Darius and destroy the fearsome Alloylantern, a mechanical fortress from which all of Belser's technological power comes. The original world of Belser is unknown, but the most prominent scientists believe it was largely oceanic, as all of Belser's technology is modeled after aquatic life forms.
