Even in Empire City, a town where weird science is the hope for tomorrow, itâ€™s hard for a robot to make his way. Itâ€™s even harder for a robot named Mack Megaton, a hulking machine designed to bring mankind to its knees. But Mackâ€™s not interested in world domination. Heâ€™s just a bot trying to get by, trying to demonstrate that he isnâ€™t just an automated smashing machine, and to earn his citizenship in the process. It should be as easy as crushing a tank for Mack, but some bots just canâ€™t catch a break.
When Mackâ€™s neighbors are kidnapped, Mack sets off on a journey through the dark alleys and gleaming skyscrapers of Empire City. Along the way, he runs afoul of a talking gorilla, a brainy dame, a mutant lowlife, a little green mob boss, and the secret conspiracy at the heart of Empireâ€™s founders---not to mention more trouble than he bargained for. What started out as one missing family becomes a battle for the future of Empire and every citizen that calls her home.
