Ghost of Tsushima gets a surprise announcement where it’ll receive an update called Legends, which adds online multiplayer 4-player cooperative mode to the game.
Introducing Ghost of Tsushima: Legends, a new cooperative multiplayer* experience inspired by Japanese folk tales and mythology. Choose from one of four classes — Samurai, Hunter, Ronin, or Assassin – and play with friends or via online matchmaking in a series of two-player story missions or four-player wave-based survival missions.
Of course, an internet connection and an active PS Plus subscription is required for you to be able to play online with other people.
The free update will be available sometime in fall of 2020.
