In 'Chrono Chums: Who's There?', players assume the role of Max, an eccentric amateur time traveler who accidentally gets trapped in a time loop after meddling with a broken grandfather clock. Armed with only their quick wit and a snarky AI assistant named C.T. (Chrono Tutor), players must navigate through different timelines, solving quirky mysteries, interacting with historical figures, and uncovering the hidden connections between various events over time. As Max explores the past, he encounters alternative versions of his own friends, called 'Chums,' each representing different choices he could have made. They may help or hinder him, depending on how he interacts with them. The ultimate goal is to break free from the time loop by understanding the tapestry of choices made, while C.T. throws hilarious banter your way. Will Max learn from his Chums, or will he remain forever caught in his own tick-tock trap?
