ELDEN RING Tarnished Edition for Switch 2 will include the main game, the Shadow of the Erdtree DLC, four new armor sets, two new character classes, and a feature to change the appearance of Torrent (3 types).
The game will release on August 28, and the new content will be released as DLC on existing platforms the same date.
They also posted new footage (looks pretty good performance wise but vegetation still looks PS4-level)
