In 'Chrono Chums: Who's There?', players take on the role of a quirky, time-traveling detective named Flux, who partners up with various historical figures - or 'Chrono Chums' - to solve timeless mysteries scattered across different eras. Each chapter thrusts you into a new timeline, from the bustling streets of Victorian London to the outer reaches of the Galactic Federation in the year 3000. Players make choices that can alter historical events and impact both their buddy's lives and the world as they know it. Using a combination of wits, humor, and keen observational skills, you must discern friend from foe, solve intricate puzzles, and unveil secrets before the timeline collapses. With each choice echoing through time, what will you sacrifice for your friends, and can you trust them when the stakes are high?
