Nayuki's Arknights: Endfield Collab Crashed Its Own App: 500-Cup Queues and Three-Hour Waits
Nayuki's Arknights: Endfield collaboration overwhelmed its own ordering system on day one: over 500 queued cups per flagship store, three-hour waits, 140 themed stores nationwide. This piece reviews the surge and the failure, and explains why the real bottleneck for IP collaborations has moved from traffic to fulfillment.
What Happened: A Surge and a Collapse in One Afternoon
Day-one numbers: 500 cups, three hours, doubled foot traffic
Shenzhen Economic Daily's Chuang report describes the September 23 launch, which added three "first-snow light cheese fruit milk" drinks. Players queued before opening at stores nationwide, many store pages displayed over 500 cups still being prepared, and foot traffic doubled. Some fans carried badge-covered ita bags to the door half an hour before opening; others traveled between cities to reach the themed locations.
The official apology: capacity restored by 4pm
Nayuki then published an apology and explanation: the ordering mini-program's servers could not handle the simultaneous traffic, causing error pages and loading failures. The company scaled capacity through the day and restored full service around 4pm on September 23. Players with defective merchandise could register for exchange through customer service, and popular items were emergency-restocked.
Chain Reaction: Scalper Markups, Sold-Out Merch and Reflex Battles
Limited merch became hard currency
The campaign included more than ten limited items such as foil cards, embossed badges and rotating stands, and 140 themed stores were dressed as a real-world Endfield supply station. Merch sold out quickly, secondhand listings appeared with markups almost immediately, and some players paid for the set without receiving the matching items.
Context: this was Nayuki's second Arknights IP campaign
Nayuki's 2024 Arknights collaboration reached 11th on Weibo's trending list and is still cited as a benchmark for Chinese game IP partnerships. This time the partner was the newer Endfield, the heat was higher, yet the supply chain was not upgraded in step. The run-up did not lack warning signs either: community threads had already flagged leaked bottled drinks and unreleased character information, signals that demand was building well before the launch date. Participation then exceeded what the brand had planned for.
Deep Dive: The Bottleneck Moved From Traffic to Fulfillment
An IP collaboration trades fandom density for store traffic and product exposure. Once arrivals outrun mini-program capacity, inventory and drink production, a surge becomes a public failure: servers, merch stock and in-store throughput are exactly the three pressure points. Tea-brand collaborations that flopped in recent years failed for the same reason, underestimating how hard fans concentrate their spending. Peak QPS limits, per-store order ceilings and merch-to-drink ratios are the variables that decide whether a campaign becomes a talking point or a public incident. The gap is not creativity, it is pre-event stress testing.
Risk Side: A Fast Apology Is Not a Fixed Problem
Nayuki responded quickly, but two risks remain. If popular merch stays out of stock for long, negative sentiment compounds in the second wave of sharing. And repetition matters: if 2024's lessons did not become 2026's contingency plan, the next campaign carries the same exposure. A third risk is resale inflation, where merch becomes a speculative asset and the people who actually want it cannot get it.
My Take: The Heat Belongs to the Game and the Supply Chain
The biggest winner here is Endfield's IP momentum: three-hour queues proved its core audience will show up offline. Nayuki captured the traffic and simultaneously exposed its fulfillment gap to everyone. The opportunity in game-IP food and beverage tie-ins remains real, but the next round will be decided by preparation. I file these cases and their numbers for follow-up on GameHub.
FAQ
When did the Nayuki and Arknights: Endfield collaboration start?
It launched on September 23, 2026, with three collaboration drinks and one bakery item across 140 themed stores nationwide.
Why did the ordering app crash?

What if I cannot get the collaboration merch?
Nayuki said it began emergency restocking, and players who received defective items can register for an exchange through mini-program customer service. Restock timing for the most popular items depends on later official notices.
