The year is 1274. Samurai are the legendary defenders of Japan — until the fearsome Mongol Empire invades the island of Tsushima, sowing havoc and subjugating the local population. As one of the last surviving samurai, you rise from the ashes to fight back, but honorable tactics alone won't win this war. You'll have to move beyond your samurai traditions and forge a new way of fighting — the way of the Ghost — as you wage an unconventional war for the freedom of Japan.
