Both The Legend of Zelda: Breath of the Wild and The Legend of Zelda: Tears of the Kingdom are getting upgrades for the Nitendo Switch 2 enhancing the visuals of the game to make use of the improved hardware.
Resolutions and frame rates are getting a bump with the new Switch 2 having an in-built 1080p screen and 4K output docked. HDR support has also been added, improving the colours of the game.
Zelda Notes is a new feature that will allow for in-game navigation in the recently announced app.
UPDATE: Nintendo Switch Online + Expansion Pack members will be able to access the respective upgrade packs for free if they own a copy of either game.
