Maintenance has been completed at the time listed above.

We sincerely apologize for the prolonged maintenance and the inconvenience caused by the issue in Fierce Battle Area.

Below is a report detailing the nature of the issue and the measures we have taken.

Issue Details

・An issue occurred starting 2025-11-05T03:00:00Z in which mission rewards and clear rewards for Fierce Battle Area (Permanent) [London] and [Tachikawa] could be obtained multiple times under specific conditions.

・As a result of the issue, players were able to obtain Dimensional Crystals (Free), Credits, Proofs of Valor, Emblems of Defense, and various items purchased with these currencies beyond the intended amount.

Measures Taken

Prioritizing fairness and data restoration for all players, we have taken the following actions:

▽ Dimensional Crystals (Free)

・All Dimensional Crystals (Free) acquired beyond the intended amount have been recalled.

・Players whose Dimensional Crystals (Free) balance fell below 0 after the recall have been temporarily restricted from logging in to allow for more accurate recall and data restoration. Details on login restrictions will follow below.

▽ Credits and Proofs of Valor

・Credits and Proofs of Valor acquired beyond the intended amount have been recalled. This adjustment will not result in a negative balance.

・To ensure fairness, we will incrementally distribute the maximum amount of Credits and Proofs of Valor that could not be recalled to all players.

However, for players from whom the items could not be fully recalled, the amount that was not recalled will be subtracted from this distribution.

▽ Emblems of Defense

・Emblems of Defense acquired beyond the intended amount have been recalled. This adjustment will not result in a negative balance.

・To ensure fairness, we will incrementally distribute a set amount of Emblems of Defense to all players.

However, for players from whom the items could not be fully recalled, the amount that was not recalled will be subtracted from this distribution.

・Additionally, players whose Emblems of Defense balance fell below 0 after the recall have been temporarily restricted from logging in to allow for more accurate recall and data restoration.

The exact amount of each item to be distributed can be found at the end of this announcement.

Login Restrictions

・As a result of the item recall, players whose Dimensional Crystals (Free) or Emblems of Defense balance fell below 0, and for whom immediate restoration is difficult, have been temporarily restricted from logging in. In addition to the restoration measures above, we will individually perform a detailed restoration listed below.

We will lift the login restrictions for these accounts incrementally as their restoration is completed. We ask for your continued patience.

▽ Gacha

・All characters, weapons, Talent Shards, Encounter Stones, THE GAME Gacha Medals, and Pickup Gacha Medals obtained from Gacha pulls using the Dimensional Crystals (Free) acquired from this issue will be recalled.

・Characters and weapons exchanged using THE GAME Gacha Medals or Pickup Gacha Medals acquired from this issue will also be recalled.

▽ Characters and Weapons

・Compensation for enhancement materials and Credits used on characters and weapons acquired from this issue is currently under consideration.

▽ Emblems of Defense

Items (Credits) that were exchanged for in excess using the Emblems of Defense acquired from this issue will be recalled.

・Dimensional Crystal x1,500

・Stamina Jelly x8

▽ Sequential Distribution

・Credit x756,670
