In 'Hello, Who's Calling?', you play as an unassuming switchboard operator in the 1980s, whose mundane job takes a dark turn when you start receiving mysterious and unsettling calls. Each caller has a secret to share. As you navigate conversations, gather clues, and unravel hidden tales of desperation, betrayal, and dark humor, you must piece together a chilling mystery that connects them all. With multiple endings driven by your choices, the fate of the callers—and possibly your own—hangs in the balance as you learn that some calls are better left unanswered.
