Developed by Microsoft Game Studios' Japanese branch, this unusual actionadventure game comes to North America thanks to Majesco. The game is set on a grim future Earth, where the incursion of a mysterious dustlike substance has brought the near extinction of the human race. The few people who survived now live underground, but have learned that the dust is not always completely deadly to them in some cases, limited exposure can actually grant them new powers and abilities. These survivors occasionally return to the Earth's surface, on missions to determine the cause of the dust.
