In 'Whose Halo Is This?', players dive into a cyberpunk metropolis where the voices of the past echo through holographic illusions. As a rogue detective with a knack for sarcasm, you find a mysterious halo device that grants you the ability to hear the last thoughts of its previous owners. Each owner reveals a facet of a larger conspiracy involving corrupt corporate overlords, unearthly entities, and the quest for lost memories. You must navigate the treacherous underbelly of the city, engage in deep conversations with a unique cast of characters, and piece together clues in order to uncover the truth behind the halo. Players will interact through choices that affect the narrative and relationships, leading to multiple endings that depend on how they solve the mystery and their moral decisions.
