Hero's Path is a feature of the Sheikah Slate in The Legend of Zelda: Breath of the Wild.
This feature is unlocked upon installation of The Master Trials DLC pack. It essentially shows a line on the Sheikah Slate's map following Link's path throughout the player's playthrough over the past 200 hours of gameplay.[1] The feature allows Link to retrace his steps and even features his crying out whenever his path reaches a game over point (which are marked on the map by a red X) before continuing to tracing his steps.
