Arknights: Endfield is making the jump from your console onto physical cups. GRYPHLINE has announced a collaboration with Happy Lemon, bringing four character-themed drinks and limited collectibles to all Happy Lemon US locations starting today, May 13th, and running through June 14th. For fans of the game near a Happy Lemon, this is the kind of real-world collaboration that feels pretty interesting to see, even if it was unexpected.
The collaboration will feature the following drinks:
- Perlica Golden Lemon Bloom: A vibrant mango-lemon slushy.
- Zhuang Fangyi Jade Latte with Salted Cheese: A refined matcha latte layered with tiramisu salted cheese.
- Ardelia Strawberry Cream: A visually striking strawberry-forward layered beverage.
- Last Rite Blue Glacier: A bold blue-toned slushy.
During the event’s promotional period, people who visit a Happy Lemon store can also get some bonus goodies depending on what they purchase, being dubbed “bundle tiers”. These two bundle tiers are the Operator Set and Squad Set, and while it seems like slightly confusing wording, it seems to work like this:
By purchasing a single collaboration drink, you’ll receive a random character coaster, an in-game reward code postcard, a paper bag, and a collaboration cup sleeve. If you decide to purchase two collaboration drinks in a single order, you reach the Squad Set bundle tier, which includes two random character coasters, one random character clear card, an in-game reward code postcard, a paper bag, a character sticker sheet, and two collaboration cup sleeves, giving those who purchase more extra goodies.
San Diego Takeover
If you’re in or near San Diego, the Happy Lemon on Convoy Street is getting a full Arknights: Endfield-themed takeover during the collaboration period. On May 23rd from 2 to 4 PM PDT, there will be a dedicated event featuring interactive on-site activities such as character photo opportunities with Endfield cosplayers, themed games with giveaways, life-size character displays, a Live DJ playing themed music, and exclusive opportunities to sample the drinks.
Activities and programming are subject to change without notice, so it’s worth checking the Happy Lemon or Endfield socials closer to the date for any potential updates. Convoy Street is also a well-known spot in San Diego, so it may be crowded depending on how many people are traveling to check out the celebration!
About Arkknights: Endfield
For readers less familiar with the game, Arknights: Endfield launched January 22nd, 2026, as the first expansion of the Arknights IP beyond just having a mobile game. It’s a 3D RPG with real-time combat, exploration, and base-building, and it carries forward the strategic depth the original Arknights franchise has been known for on mobile, keeping the core of what made it a popular franchise. The original Arknights has exceeded 100 million downloads, which gives you a sense of the community behind it. Endfield is free to play and is available on PS5, PC (Epic Games Store & Special Launcher), and mobile devices.
