Ghost of Tsushima tells the story of Jin Sakai, a samurai fighting to save his homeland from the first Mongol invasion in 1274, where he must abandon the honorable samurai code for stealth and cunning tactics (the "Way of the Ghost") to defeat the overwhelming forces led by Khotun Khan, ultimately saving Tsushima but facing internal conflict over his transformed identity and strained relationship with his uncle, Lord Shimura.
