In 'Chrono Chums: Who's There?', players assume the role of Rex, a maladjusted time-traveling detective with a penchant for overcooked breakfast foods and poorly timed puns. Players sift through different time periods, from the Age of Dinosaurs to a dystopian future, to unearth clues about a mysterious figure manipulating time itself. Alongside quirky companions from each era—think a dinosaur with a penchant for dramatic monologues or a punk rock futurist—players will solve puzzles, engage in witty banter, and navigate timelines marred by paradoxes and miscommunication. The narrative unfolds based on player choices, revealing how each decision shapes not only the fates of the characters but the very fabric of time.
