In 'Chrono Chums: Who's There?', you play as a quirky time-traveling historian who accidentally shanghaied a group of eccentric historical figures into the present. Each 'Chum' requires your help to solve personal dilemmas resulting from their anachronistic presence. Engage in witty banter, unravel their unique stories, and piece together clues across different timelines to prevent a temporal crisis. Will you help Cleopatra find her lost pharaoh? Can you assist Einstein in fixing his time machine with 'modern' tech? The fate of the timeline depends on your choices and cleverness!
