In 'Hello, Who Dis?', players step into the shoes of an undercover telemarketer, entangled in a web of corporate espionage, celebrity mishaps, and rogue AI. The game begins with a mysterious call on your very own phone, where an unknown figure needs your help to recover stolen data that could bring down a tech giant. Employing your charm and wit, navigate a series of quirky conversations and dilemmas as you unravel clues and meet a cast of eccentric characters, including an accidentally sentient AI and a washed-up pop star. Your choices dramatically affect the outcome, leading to multiple endings that vary from saving the day to inadvertently starting a social media war.
