Gryphline is launching a collaboration between 'Arknights: Endfield' and GS25. Titled 'Endfield Industries' GS25 Pioneering Operation,' the collaboration runs until June 15 and features a variety of co-branded products, including lunch boxes, burgers, chocolates, and snacks, along with limited-edition merchandise.

Purchasing any of the five collaboration lunch boxes provides a coupon for an in-game profile frame and 5,000 Talosian currency. Buying one of the five burgers—such as Perlica's Nashville Chicken Leg Burger, Zhangbang's Truffle Cheese Burger, or Levatine's Egg Hamburg Burger—grants a random photo card from a set of 26 featuring key characters. The lunch boxes will be sold only until May 15, while burgers and other items will be available at GS25 stores nationwide until June 15.

On the 23rd of this month, 'Gilberta's Energy Chocolate' will be released, each containing one of 10 character photo cards featuring Perlica, Zhangbang, and Gilberta dressed as GS25 employees. Starting the 29th, Levatine's Spicy Seafood Chips, Last Light's Energy Cube Jelly, and Perlica's Lemon Wafers will also go on sale, all featuring a collection of 40 'ttibu-ttibu' stickers.

A stamp rally event will also be held via the 'Our Neighborhood GS' app. By collecting a certain number of stamps from purchasing collaboration products, users can enter a drawing for a chance to win limited-edition merchandise, including administrator IDs, game coupons, commemorative coins, keycap keychains, framed mood lights, and clear files.

Special offline stores will also be operated. At five locations nationwide—Seoul Hapjeong Premium, Gangnam Dongwon, and The Gwanak; Daejeon Complex Terminal 1; and Busan General Terminal—customers can purchase store-exclusive merchandise such as LD acrylic stands, SD acrylic dioramas, and LD desk mats.

An offline event will be held for three days from the 24th to the 26th of this month at Mapo Point in Mapo-gu, Seoul. The event will operate on a timed reservation basis and offer prizes like administrator IDs, clear files, and photo cards through activities such as 'You'll pull for us, right?', '80m, reaching out to you', and 'Can't stand the loss of efficiency!'. Taking a photo at the on-site environmental observation booth will also provide a chance to win one of the limited-edition items.
