Capcom going to release on August 25, 2017 this week in Japan the Monster Hunter XX Nintendo Switch Ver. As we already reported before you can move the save data file from the original Nintendo 3DS version to the Switch version so you can continue the game where you left it on your 3DS.
The application for the data migration is available from today in the Japan eShop for FREE. It should be noted that you can migrate the save data file from the original Monster Hunter X and not just from the XX. With the latst update for the 3DS version (which released today) you can also enjoy the new communcation function with the Switch version.
