Blood Message is a narrative-driven, linear action-adventure single-player game based on the true historical event of "Dunhuang's Uprising". Set in the late Tang Dynasty in 848 AD, players take on the role of Dunhuang, a messager who embarks on a perilous eastward journey to deliver a message that holds the fate of his homeland. Alongside his son, they must survive relentless enemy sieges and a treacherous three-thousand-li odyssey, fighting against impossible odds to return to the heart of the Tang: Chang'an. Amidst the desert sands, they etch the final tale of loyalty in the Great Tang. The world has heard too many stories of emperors and generals—Blood Message is an ode to the unsung heroes.
