In 'Who Are You Calling Hello?', players step into the shoes of a snarky telemarketer who discovers an underground conspiracy while making calls from their cubicle. The game is set in a hilariously exaggerated version of the corporate world, where players must navigate through absurd scenarios, engage in witty banter with quirky clients, and solve riddles that hint at a larger plot involving corporate espionage and secret identities. As calls progress, the player gathers clues to piece together the mystery and make crucial decisions that will impact the outcome.
