Tarnished Edition includes both the base game and the Shadow of the Erdtree expansion.
New players simply install the game and start a new character. You begin in the base game as normal, and the DLC content becomes available later in the playthrough once you reach its required bosses.
Returning players can continue using their existing save file. As long as Tarnished Edition (or the DLC) is installed, your character will automatically gain access to the expansion when the in game requirements are met.
Tarnished Edition is not a separate mode — it’s the complete game with the DLC already included.
