In 'Chrono Chums: Who's There?', players step into the shoes of Nia, a quirky time-traveling protagonist with a knack for attracting the oddest companions from various eras. When an interdimensional anomaly begins pulling people out of their timelines, it's up to Nia and her eclectic crew – from a disgruntled Roman centurion to a cynical 1980s hacker – to unravel the mystery of the disturbance. Players make choices that affect character relationships and the narrative, leading to multiple possible endings that explore themes of friendship, belonging, and the hilarity of mismatched time periods. Can Nia keep her chrono-chums in line while fixing the timeline, or will their antics send history spiraling out of control?
