Zone of the Enders

Series
One sequel exists, Zone of the Enders: The Second Runner (known as Anubis: Zone of the Enders in Japan), also for the PlayStation 2. There was also a spin-off turn-based strategy title named Zone of the Enders: The Fist of Mars, and an anime series named ZOE: 2167 IDOLO.

While ZOE focusses mostly on the loss of innocence of a child faced with having to kill to survive, IDOLO and The Fist of Mars explore issues surrounding terrorism and ideological warfare.
