Follow-up Measures on Issues After the Unity Version Upgrade on 5/28/2026

As part of the Scheduled Update on May 28, 2026, we upgraded the game's Unity version. Following this update, however, some AOS and iOS environments have been experiencing issues that prevented players from accessing or progressing through the game properly. The process of resolving these issues has taken considerable time, resulting in prolonged inconvenience.

We sincerely apologize for the lack of stable service.

Please refer to the information below on what has been confirmed so far and our planned follow-up measures.

1. Impact of the Engine Upgrade - Following the Unity version upgrade in the 1.106.0 update on May 28, 2026, an issue occurred where certain resources required to run the game were not being loaded in the correct order - The resulting "unable to connect" issue was initially resolved through the update on June 1 at 22:00

2. Increased Memory Usage - Following the engine upgrade, the amount of RAM required during the game's launch process has increased - As a result, some devices are experiencing screen freezes, unresponsive game application, or forced shutdowns

3. Current Measures To resolve this issue, we are working closely with Unity's technical support team on memory optimization and other related work for devices experiencing the issue

1. Below are the "devices prone to repeated forced shutdowns" as identified by our development team: AOS: Devices using Adreno 720 series GPUs iOS: Devices with 4GB of RAM or less, or devices running iOS 26.4 or later versions (* In particular, we have confirmed that iOS 26.4 and later versions exhibit higher memory usage by the operating system itself. As a result, the available RAM for game launch may become insufficient, leading to forced shutdowns)

※ To set clearer specifications for stable gameplay, the minimum device requirements for Limbus Company will be adjusted. The updated minimum requirements and their effective date will be announced via a future notice.

We are currently working to resolve the root cause of the forced shutdown issues occurring in both AOS and iOS environments. However, this issue involves several complex technical factors, including differences in OS versions, device-specific hardware specifications, and the engine's memory handling process. As a result, we have not been able to provide a swift solution that meets our Managers' expectations.

We sincerely apologize for the frustration caused by the delay regarding this issue.

※ Recommended Gameplay Environment (Temporary)

Until this issue is resolved, please access the game on a different mobile device or PC (Steam) with more RAM availability. We sincerely apologize for the inconvenience.

Please note that the above is only a temporary guidance, and we are committed to ensuring a more stable gameplay experience on mobile platforms.

Managers who have records of unclaimed Monthly Lunacy Supply due to the inaccessibility issue will be compensated with an equivalent amount of Lunacy for the number of days they were unable to claim them.

• Recipients All Managers who were unable to claim their Monthly Lunacy Supply due to the inaccessibility issue from May 28th, 2026 Scheduled Update to Jun. 25th Scheduled Update

• Lunacy Compensation Lunacy equivalent to the amount Managers were unable to claim over the inaccessibility period

• Distribution Date Lunacy compensation will be distributed simultaneously for the affected users after the Jul. 16th, 2026 Scheduled Update

We sincerely apologize to Managers who have been unable to access the Ch. 9.5-2 "Mnestic Experience" due to the inaccessibility issue.

However, due to the high level of variance of issue details and persisting duration between each Manager, which depend on a wide range of factors such as device specs, OS versions, GPU series, RAM size, and access environment, it is difficult to set a concrete compensation criterion for each Manager.

As such, we will be distributing "Photos", the event currency for Ch. 9.5-2 "Mnestic Experience", for all Managers.

Please note that this method of compensation has been decided in consideration of the scale and the duration of the issues that occurred after the May 28th Unity version upgrade. As it is an exception to our standard compensation process, it will be limited to the "Mnestic Experience" event.

• Recipients All users whose game accounts were created before Jul. 16th, 10:00 AM (available for 7 days)

• Content Ch. 9.5-2 Mnestic Experience Event Currency "Photos" - x1000

• Distribution Date Lunacy compensation will be distributed simultaneously for all users after the Jul. 9th, 2026 Scheduled Update

※ Relevant Compensation can be claimed until Jun. 11th (Thu), 2026, 10:00 (KST) via the in-game Mailbox. ※ Event currency in your inventory maxes out at the amount required to exchange for all event rewards. ※ If claiming the currency will exceed the above amount, any surplus event currency will be lost. ※ This event currency will become unusable if claimed after Jul. 16th, 2026 (KST). ※ Please make sure to claim and spend the event currency before the event ends.

We sincerely apologize for the inconvenience.

Thank you.
