■ I want to link my player data from mobile device to Steam.
After launching the Steam version app, you can link your player data from Title Menu (≡) > Data Transfer.
*Please note that you cannot link your account with Steam from global menu (////) at the top right of the game screen > Menu (≡) > Account Linking.
You can link your Steam account by performing Data Transfer using the Google/Apple account that is linked to your current player data.
▼ Steps for Data Transfer
1. Launch the Steam version app and tap the Title Menu (≡) on the right side of the title screen, then select Data Transfer.
2. Select the Apple/Google account that is linked to your game account.
3. Log in to your selected account.
*Please note that your player data will be linked to the Steam ID that is currently logged in.
*Please confirm that the Steam ID you wish to link is correct, as you will not be able to unlink your account once the Steam ID has been linked.
■ "Data Transfer Failed" appears while performing Data Transfer on Steam
The error message may be displayed when your player data is not linked to your Apple/Google account.
Please perform Account Linking with your player data and try the Data Transfer again.
■ "This player data is already linked to another Steam account." appears while performing Data Transfer on Steam
The Steam account you are currently logged into is not the one you previously used to perform the Account Transfer.
If your game data is linked to a different Steam ID, please switch to another Steam account and log in.
■ Different player data linked to Steam while performing Data Transfer
If you perform Account Linking with newly created player data and link it to an Apple/Google account which is already linked to your existing player data, the previous link between Apple/Google account and your existing player data will be automatically removed.
Please link your former player data to the same Apple/Google account again before attempting the Data Transfer on Steam once more.
