Ghost of Tsushima is a 2020 action-adventure game developed by Sucker Punch Productions and published by Sony Interactive Entertainment. The player controls Jin Sakai, a samurai on a quest to protect Tsushima Island during the first Mongol invasion of Japan. Jin must choose between following the warrior code to fight honorably, or using practical but dishonorable methods of repelling the Mongols with minimal casualties. The game features a large open world which can be explored either on foot or on horseback. When facing enemies, the player can choose to engage in a direct confrontation using Jin's katana or to become a legendary warrior known as "the Ghost" by using stealth tactics to assassinate opponents. A multiplayer mode titled Ghost of Tsushima: Legends was released in October 2020 and made available separately in September 2021.
