In 'Chrono Chums: Who's There?', players assume the role of a quirky time-traveling detective named Max, who discovers that their closest friends—known as the Chrono Chums—have mysteriously disappeared across different timelines. Each friend is stuck in an alternate version of reality, from a futuristic utopia to a chaotic medieval tavern. To rescue them, players must navigate sharp-witted dialogues, make clever choices, and solve intricate puzzles that intertwine with the fabric of time itself. The game offers multiple branches that change based on players' choices and the friendships they nurture with the Chums, turning their rescue into a laughter-filled journey through history's strangest moments, all while evading the shadowy Time Syndicate that seeks to exploit the timeline for its nefarious schemes.
