Arknights: Endfield's 1st Anniversary Festival Set for January 2027
Anniversary Events and Collaborations Planned
GRYPHLINE has officially confirmed that Arknights: Endfield's 1st Anniversary Festival will take place on January 10 to 11, 2027, at the Makuhari Messe International Exhibition Hall in Japan. The announcement arrived alongside new illustrated art of operators Liino, Rossi, Argent Flow (also known as Minho in JP), and Si to welcome the milestone. The festival will celebrate and look back on the game's first year, though specific details and in-game events will likely be released closer to the game’s anniversary.
The news came during the Sanctuary of Ink Livestream, which also introduced Endfield's new core chapter and version updates. The broadcast covered details on a new playable area, rewards, and upcoming operators, along with the anniversary and collaboration events.
Round1 and ZONe Energy Collaborations Soon
In addition to the events, two new offline collaborations were also confirmed. A collab with Round1 will run nationwide in Japan from November 10, 2026, through February 10, 2027, featuring bowling, collaboration karaoke rooms, an AR stamp rally, and limited-edition merchandise. This was also confirmed for the United States, running the same November 10 to February 10 window, with details to follow.
Endfield is also partnering with ZONe Energy, Suntory’s popular energy drink brand in Japan, with limited Original Towel Packs launching October 27, 2026, at Aeon, Aeon Style, and MaxValu stores nationwide, excluding Okinawa. Each pack includes 3 bottles of HYPER ZONe and a themed towel featuring one of the six available operators: Camille, Si, Typhoeus, Mi Fu, Liino, or Rossi. The products will be sold on a first-come, first-served basis while supplies last.
