Sony presented the first gameplay trailer for Ghost of Tsushima during the company's E3 2018 press conference. It opened with a samurai walking out of a forested area with his horse, he keels down and picks up a leaf, before the wind carries it away. Text appears on screen to denote it's Day 9 of the Mongol invasion, indicating the game will track progression by splitting them into days.

The character walks up a hill and looks over Otsuna Grassland, a beautiful field where wheat gently sways in the wind. The samurai calls his horse and begins riding. The game looks absolutely stunning. Eventually the samurai makes his way deep into the forest, where he encounters invading forces killing someone. The three enemies square off, but the samurai adopts a defensive stance, delivers a devastating counter, and cuts his foes down.
