Overview

Thank you for playing KAIJU NO. 8 THE GAME.

To protect your game data, we ask that you link your account.

 Account Linking

Additionally, if your current device malfunctions or if you wish to change devices, you can transfer your player data to the new device.

 How to Link Your Account

You can link your account to your Apple Account or Google Account.

Steps to Link Account:

FAQ: Regarding Account Linking

Q1: How do I restore my data or transfer my account?
A1: Access Title Menu (≡) on the title screen, select Data Transfer and follow the on-screen instructions.

Q2: After transferring account, will I be able to pick up my game progress from when I linked my account?
A2: You can proceed with the game from when you were last online. For example, if you link your account when a mission is ongoing and transfer your account after clearing the mission, the game will proceed from the time when the mission is cleared.

Q3: After transferring my account to a different device, can I still play on the original device?
A3: Yes, you can play on both devices. However, you cannot log in to the same account on both devices simultaneously. If a new login is detected on a device, you will be returned to the title screen on the previous device.

Q4: Will my linked account be unlinked if I delete my player data?
A4: No, deleting your player data will not unlink your account. To unlink an account, go to Menu (≡) > Account Linking.

Q5: I wish to change my linked account.
