In Freedom Wars, you’ll be playing alongside others to take down giant Abductor enemies to mitigate your million year prison sentence. You’ll also have android partners called Accessories that can be fully customized from voice to looks.
Lilly is a mysterious female character in the Panopticon who was rescued by the protagonist. Even after being rescued, she remains active as a prisoner.
