In 'Chrono Chums: Who's Hello Is It Anyway?', you play as Eddie, a socially awkward time traveler who accidentally opens a portal that pulls characters from various historical eras into the modern world. Now, it's up to you and your quirky group of 'Chrono Chums'—ranging from a Victorian inventor to a disco-loving ancient Roman—to navigate the ups and downs of different time periods and prevent a timeline catastrophe. You must convince your new friends to help you gather the 'Time Tonic' needed to seal the portal, while also dealing with hilarious misunderstandings and unexpected friendships. Choices you make will affect your relationships with these characters, the timeline they came from, and ultimately, the fate of history itself!
