Project Moon's Limbus Company completed its three-part Main Story Chapter 10 rollout on October 1, 2026, and the Steam version reached 151,455 peak concurrent players within 24 hours of the final part's release. That figure is the game's second-highest on record, behind 157,444 set on July 9 during the 9th Walpurgis Night event.
Limbus Company's latest major content push finished on October 1, 2026, when Project Moon implemented the third and final part of Main Story Chapter 10. The chapter was released in three weekly parts, on September 17, September 24, and October 1, and it changed how the game presents exploration: Chapter 10 adds a top-down perspective system in place of the visual novel format. Project Moon also made the chapter accessible early by clearing Chapter 1, so new players can reach the new system sooner. The September 24 update, the middle step of the rollout, adjusted enemy attack speed in specific stages, shortened input delay, and added a key-rebinding feature for the Steam version.
Player numbers followed the rollout. Within 24 hours of the October 1 release, the Steam version hit 151,455 peak concurrent players as of around 17:00, per the unofficial database SteamDB. That is second to the all-time high of 157,444 recorded on July 9 during the 9th Walpurgis Night event. The two peaks arrived under different conditions: the July record came during a limited-time event, while the Chapter 10 high came without one.
The July 9 event also produced the year's largest audience and the year's most visible operational problem. Servers came under strain during the 9th Walpurgis Night surge, and Project Moon distributed 1,300 Lunacy as both an apology and a celebration of the record. The same event marked the top of a growth curve: previous Walpurgis Night peaks rose from 12,000 in the first event to the July figure.

Oct 3
Project Moon implemented the final part of Limbus Company's Main Story Chapter 10 on October 1, 2026, completing a staged rollout that began September 17. The chapter introduces a top-down perspective exploration system, a departure from the visual novel format the game previously used, and was released in three parts over three weeks: the first on September 17, the second on September 24, and the third on October 1. Within 24 hours of the third part's release, the Steam version reached 151,455 peak concurrent players as of around 17:00, according to the unofficial database SteamDB. That figure is second only to the all-time high of 157,444 recorded on July 9 during the game's 9th Walpurgis Night event. Chapter 10 can be accessed early by clearing Chapter 1, a design choice intended to let new players experience the new exploration system sooner. A September 24 update also adjusted enemy attack speed in specific stages, shortened input delay, and added a key-rebinding feature for the Steam version.
Jul 9
Project Moon's Limbus Company reached a new concurrent player peak of 310,000 during the 9th Walpurgis Night event on July 9, 2026. The surge overwhelmed servers, causing instability. The developer announced it would distribute 1,300 Lunacy as both an apology for the issues and a celebration of the record. The game's player base has grown with each seasonal event, with previous peaks rising from 12,000 in the first Walpurgis Night to this new high.
