It is believed that long before human civilization, Mars was home to a highly advanced society. A powerful sorceress wiped out this civilization and all knowledge of it, leaving behind only a single artifact known as "INFINITY." By the year 2100, Earth was suffering from catastrophic food shortages that led to widespread famine and global civil wars. However, centuries later, the world government launched a colonization effort on Mars, which gradually began to alleviate these crises. On a nearby Martian farm, the Infinity chip was uncovered, revealing the lost technologies of the ancient civilization. In 2309, Mars issued a Declaration of Independence from Earth. Massive military forces were assembled on the Red Planet, with a vast armada prepared to defend against any Earthly assault. In response, the Earth government dispatched a fleet of warships, accompanied by a specialized aerial strike force known as ACID. ACID is armed with a cutting-edge fighter jet called the Mosquito. Their objective is to infiltrate Mars, halt the rebellion, track down the rebel leader—and stop them, no matter what they are.
