Content Ratings

No Romance
There is no romantic content; friendships and loyalties remain the central relationships.
Mild Themes
Corporate monopolization of power and technology, the ethics of artificial intelligence obedience, and the continuity of Cole's rescue mission are the primary concerns.
Mild Violence
Corporate enforcers, mechanical threats, and action-adventure combat create consistent excitement; violence is appropriate for the age group.
Synopsis

Cole and friends enter Zeropolis, a kingdom of technological magic where robots and mechanical wonders coexist with a threatening corporate power structure, and discover a conspiracy that threatens the stability of the Outskirts. A third installment that introduces an entirely new aesthetic register to the series.
