In a world where shadows have minds of their own, players step into the shoes of Sam Sable, a witty shadow detective with the ability to communicate with the shadows of others. When a series of shadowy crimes—such as thefts of color and light—plague the city, it's up to Sam and their quirky shadow sidekick to uncover the truth behind the mysterious vanishing shadows. Travel through dynamic environments that shift based on the light, solve puzzles by interpreting shadow behavior, and interact with a vibrant cast of characters whose true natures are revealed through their shadows. As secrets unfold, players must determine which shadows are friend or foe while balancing the fine line between light and dark.
