Because Monster Hunter Stories 2: Wings of Ruin had a major demo before the release, many players there were already exploring the world, getting Monsties and looking for armor, weapons and resources. For those who are wondering if your progress is coming with you, the answer is yes.
Players who have already taken the time to demo and who are still playing on the Nintendo Switch must go through a fairly easy process. Buy and install the game first, then run it. When the game starts, it tells you that there is no data to save and asks if you want to create a new file to save. This is not strictly true, but if players press Create, it will run a new save file without overwriting anything that already exists.
When you get to the main menu, you’ll see a new option that says “convert from demo”. Touch this option to set your demo information in a new file to save and you’ll be happy. All your progress will be transferred and you will follow the example where you stopped in the demo.
Unfortunately, if you have decided to play the entire game on Steam, you cannot transfer your switching process to your PC.
