The Legend of Khiimori is a survival-focused open-world game set in 13th-century Mongolia where players act as Yam courier riders tasked with delivering cargo across harsh terrain. Unlike typical adventure games, it emphasizes system-driven mechanics such as managing your horse’s mood, stamina, and physical traits, as well as balancing cargo weight to avoid injuring your mount. The game, currently in Early Access with a full release planned, draws inspiration from Death Stranding and features player-driven storytelling through interactive systems rather than scripted narratives. Players must carefully care for their horses by feeding, watering, grooming, and addressing injuries, while also navigating environmental challenges like cold mountain passes, deserts, and storms.

Players begin by purchasing one of three starter horses, each with unique stats and breeds, and can later breed horses to pass on traits. Cargo management is critical, requiring balanced saddlebags and strategic inventory decisions, especially since some quest items cannot be dropped. Survival also depends on preparing for Mongolian weather and wildlife threats, using tools like bows and powder pouches for defense. The game rewards patience and preparation over speed, with designated campsites for resting and autosaves tied to dismounting or camping. Quality-of-life settings, such as disabling the item pickup camera effect and utilizing storage chests, help streamline gameplay. The developers plan to expand features like horse taming and a full narrative in future updates.
