In 'The Hello Protocol,' you play as Max, a quirky paranoid investigator who believes that every generic 'hello' in the city is part of an elaborate conspiracy. As you journey through the eccentric neighborhoods filled with odd characters, your mission is to unravel the mystery behind a series of seemingly benign greetings that hold the key to a citywide secret. With the aid of your eclectic group of friends—each with their own absurd personal theories—you must navigate bizarre situations, make pivotal choices, and uncover whether the polite 'hellos' are a harmless phenomenon or a covert mind-control scheme. Get ready for riddles, unlikely alliances, and a whole lot of miscommunication as you attempt to decode the truth.
