The official Nintendo website has revealed an important detail about Wolfenstein II: The New Colossus for Nintendo Switch.
A note on the page says “A microSD card (sold separately) may be required to download this software. Upon release, at least 23 GB of free space will be required to download this software.”, indicating that players will need at least 23GB of space to download the game.
As Wolfenstein II’s eShop listing states the game’s file size is 13GB, it’s highly likely the Game Card itself has 13GB of content, and the remaining 10GB has to be downloaded online.
Wolfenstein II launches June 29, 2018 on Nintendo Switch.
