CYAN BRAIN, developed by NEKOUJI STUDIO, is a dystopian sci-fi side-scrolling action-shooter that explores themes of identity, survival, and the cost of power in a ruined world. The game follows a nameless protagonist who awakens in a colossal ruin with no memories, forced to battle entities created by "the Church"—an organization that previously reshaped her body into a living weapon.
