CYAN BRAIN — Dark sci‑fi action

CYAN BRAIN is a decadent side‑scrolling sci‑fi action‑shooter that follows a nameless girl (protagonist voice: Momoka Kosuzu) awakened inside a colossal ruined city. Transformed into a living weapon by a fanatical organization known as the Church, she must cut through deranged machines and mutated foes to reclaim her memories and discover the truth behind the devastation.

The narrative is a bleak fable of annihilation and devotion, driven by memory fragments and the relationships you form along the way. As you progress the "end of fate" draws nearer — but every battle strips away more than just armor.
