Later this month Nintendo will release the first DLC pack for Zelda: Breath of the Wild, with the company announcing the news during their E3 2017 spotlight event.
The second DLC for Breath of the Wild is a story DLC release, which will be 'The Champions' Ballad', sounding like a prequel story to the main game. The June 30 release will see the 'Master Trials' DLC for Zelda: Breath of the Wild, with a video on the expansion pass embedded above.
Nintendo explains: "If you own The Legend of Zelda: Breath of the Wild, the Expansion Pass grants access to three new treasure chests, DLC Pack 1, "Master Trials," and DLC Pack 2, "The Champions' Ballad," as they are released. DLC Pack 1 "Master Trials" includes: Trial of the Sword, Master Mode, Hero's Path, Travel Medallion, Korok Mask and eight new armors. Master Trials - DLC Pack 1 will be available June 30, 2017".
