In 'Chrono Chums: Who's There?', players step into the shoes of Zane, a sardonic time-traveling historian who accidentally rips a hole in the space-time continuum while trying to impress his nerdy friends. Instead of slipping into the past unnoticed, Zane discovers that each time jump summons eclectic historical figures into the present — from Cleopatra's witty banter to Einstein's wild antics. Players must navigate chaotic gatherings, solve riddles involving time paradoxes, and forge alliances with these personalities to fix the timeline while keeping them entertained. Dramatic choices will affect both the timeline and Zane's relationships with his chrono-chums, leading to multiple endings and unexpected alliances.
