Overview

Thank you for playing KAIJU NO. 8 THE GAME.

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