In 'Paradox Chronicles: Hello, Who?', players take on the role of Alex Pendleton, a once-prominent physicist turned amateur detective after accidentally inventing a device that opens doors to parallel timelines. When a mysterious figure starts manipulating events across these realities, you must navigate through different timelines to solve puzzles, gather clues, and prevent a catastrophic paradox that threatens existence itself. Each choice you make alters the timeline further, leading to wildly different world scenarios and unexpected allies or enemies. Will you unravel the conspiracy before time unravels?
