It is the twenty-seventh century. Humanity is at war against a robotic alien race which calls itself the Mechrion, whose true intentions are unknown. We have all but lost. Our last two cities, Fortress and Sanctuary, are under constant siege from these invaders, and are defended by a mechanized infantry corps called the Archangels. Strongest among them are the Titanmasters, pilots of humanity's greatest weapons, the Titans.
  It is these Archangels that stand alone against the alien threat, but even with all their terrifying splendor, it seems they only delay the inevitable.
