Genshin Impact, the action-RPG from miYoHo is available on PC, PlayStation 4, Android, and iOS, and the game also features crossplay, allowing players on all platforms to play together in the same game.
If you are wondering if the game has a cross-save feature, and if you can play on the same account across all platforms, the answer is a little complicated. Cross-save can be used on PC, Android, and iOS, but cannot be used on PlayStation 4. If you are playing the game on Sony’s console, then you will not be able to transfer your save data to another device if you want to take the game on the road or play at your PC instead.
The reason for this seems to be that the PlayStation 4 version uses information that is locked to your PSN account, while the PC and mobile versions all use a miYoHo account instead.
All you need to do on PC, Android, or iOS is start up the game and then log into the miYoHo account that you wish to use, and you will be able to pick up where you left off on that playthrough.
At the moment, we do not know if this will also apply to the Nintendo Switch version when it eventually launches, but we image that it will once again use information tied to your Nintendo account, rather than a miYoHo account, so we expect it will be the same as PlayStation 4 in that regard.
