GRYPHLINE announced on the 23rd that a collaboration between Arknights: Endfield and Frank Burger has officially kicked off. The event runs until August 22 at Frank Burger locations nationwide, featuring a trio of special menu items: the Wulung Set, the Endfield Industrial Set, and the Ceshika Side Set.

Customers who purchase the collaboration menu items will receive various commemorative merchandise. Depending on the set ordered, patrons can receive desk mats, acrylic stands, or acrylic keyrings, with three designs available for both the stands and keyrings. A CDK photo card containing in-game coupons is also included with every purchase.

Additionally, 12 locations across the country, including the Sinchon Sogang University, Banpo Sinnonhyeon, and Myongji University branches, have been transformed into special themed stores. The Sinchon Sogang University branch will host a three-day semi-pop-up event from the 24th to the 26th. Visitors can book their slots via the Naver reservation page to receive exclusive perks such as administrator badges, etched medal stickers, and collaboration stamps.

At the semi-pop-up event, those who purchase collaboration burgers will receive raffle tickets for a chance to win postcards, laser tickets, a three-piece ID photo set, and clear files. The event also offers opportunities for commemorative photos with cosplayers, and visitors who share their visit on social media with specific hashtags will receive a three-piece photo card set.

Meanwhile, GRYPHLINE previously held a pre-event from July 10 to July 20, where the character Pelika personally delivered collaboration burger sets to fans who submitted their stories.
