[Updated] Regarding Currently Confirmed Issues

Thank you for playing KAIJU NO. 8 THE GAME.

We would like to inform you of the issues we have currently confirmed.

We sincerely apologize for any inconvenience.

The issues are scheduled to be fixed in a future version update.

We will make another announcement or update this one once the fix is complete.

Resolved Issue

Updated 2025-11-04T11:00:00Z

・An unintended image was displayed for Training: Unimaterial [Caudata-Type Kaiju α].

*This was only a display issue. The obtainable materials remain unaffected.

Ongoing Issues

・Certain achievements may not show as "Completed" after you meet their conditions and tap to claim the rewards.

*This is only a display issue. The achievement is correctly completed and the rewards are received as intended.

・When pressing the "i" button while comparing equipment in Unipart R&D, a set effect that is currently not activated may be displayed.

・The filter option for ★2 materials is unavailable in Unipart R&D.

・On certain devices, an error message may appear after a return confirmation message when you take a specific backward navigation action on the End of Expedition screen.

*When the error message appears, you will be returned to the title screen. Loot and EXP are still correctly obtained.
