奇异贤伴 爱达之歌

You and an AI mech named Magus explore a dystopian landscape in the year 2222. A catastrophic poisonous rain event known as Tears of the New Moon nearly eradicated the human race — survivors fled to the underground city of Amasia. To survive, the player character known as a “Drifter” must sell AO Crystals, which can only be harvested from the polluted outside world. To travel, you’ll drive around in a vehicle called the Cradle Coffin, which you can customize. The game will also have a unique PvP option, wherein playing online will support encounters with others plays on their own missions - you might collide head to head while trying to gather precious supplies

The year is 2222. It has been years since “Tears of the New Moon”, a mysterious rain, poured and wiped out almost the entire human race. The poisonous rain gave birth to deformed creatures devouring for humans, and humanity fled from the danger. As means for survival, the humans then build an underground haven; Amasia. In this new built dystopian city, on a pursuit of maintaining their existence, they run into an Artificial Intelligence named Magus. Not knowing how things will work between them, the story of how Humans and AI coinciding and trying to find their truths begin.
