Azure Wing: Rising Gale

Based in a Dystopian future, a young soldier wakes up from stasis to find himself in a land he no longer recognizes, surrounded by primitive humans wielding nothing more then wooden sticks.

Being considered an "artifact" by these cave dwelling humans, he must find out what has happened in the time he has been frozen and how long he has been trapped in time.

Armed with his battle suit, an Advanced A.I. named Joan and outdated knowledge of the terrain he once called his battlefield, he begins his journey to learn what has happened to his species and the world.
