Zenless Zone Zero’s Version 1.2 update, Tour de Inferno, arrived in late September 2024, and its companion invite event turned New Eridu into a bustling reunion party. In 2026, that campaign is long finished, but it remains a fascinating case study in how HoYVerse coaxed lapsed Proxies back into the city. The pitch was simple: bring a friend back, link an invite code, complete a few missions, and watch Polychromes pile up like cassette tapes in a Bangboo’s backpack. 🎮
The event ran from 2024/09/25, once Version 1.2 went live, through 2024/10/21 at 00:00:00 (UTC+8). During that window, active Proxies could share an exclusive invitation code. If an eligible returning Proxy linked it and completed the relevant missions, both sides could earn rewards. The headline number was up to Polychrome ×510 and lucky draws ×20 for the inviter. Returning Proxies could also snag an extra Polychrome ×60 just for successfully linking a code, pushing the potential total to Polychrome ×570. That was a pretty sweet deal, especially for players who had been saving for a new Agent or W-Engine. 💎
Here is how the reward math broke down:
| Reward | Amount / Notes |
|---|---|
| Polychromes for inviting and missions | Up to ×510 |
| Lucky draw attempts | Up to ×20 |
| Bonus for Returning Proxy linking code | ×60 |
| Potential combined total | ×570 |
Lucky draws were the real sparkle. Proxies could use their draw attempts to chase a prize pool that felt almost too generous for a web event:
| Prize | Quantity |
|---|---|
| PlayStation®5 | ×10 |
| Anby Demara 1/7 Scale Figure | ×20 |
| Character Stand (Random) | ×100 |
| Acrylic Stand (Random) | ×150 |
| Character Chibi Stand (Random) | ×200 |
| Polychrome ×5 | Can get up to Polychrome ×20 |
| Official Investigator Log | ×2 |
| W-Engine Power Supply | ×2 |
| Bangboo Algorithm Module | ×2 |
| Denny | ×1,888 |
At the time, HoYVerse noted the Anby Demara 1/7 Scale Figure would ship around August 2025 due to production. By 2026, that window has passed, but the original caveat is worth remembering: shipping damage happens, and winners were advised to contact the shipping company first. It was a gentle reminder that even virtual rewards can stub their toe in the real world. 🎁
Who counted as a Returning Proxy? The requirements were specific, and they still matter for anyone studying similar events:
-
The Proxy had not logged into Zenless Zone Zero for 14 consecutive days or more.
-
It had been 40 days or more since the Proxy activated the ‘Back in Business’ event.
-
The Proxy had completed the Chapter 1 Story Commission ‘Earlybird Ticket to Safety.’
The duration of Returning Proxy status matched the duration of the in-game ‘Back in Business’ event. If a player shifted from active to returning during the event, existing mission progress was retained, earned rewards could still be claimed, and leftover draw chances remained usable. Logging in before the event ended allowed Proxies to keep completing web tasks and claim whatever remained. That flexibility was not small potatoes; it meant latecomers were not automatically left out in the cold.
The event page itself could be a little shy. HoYVerse warned that returning Proxy status might take 2–4 minutes to update, so refreshing too quickly was like knocking on a door before the Bangboo had finished unlocking it. Patience was part of the process. Proxies who waited, refreshed, and checked again usually found their status settled without much drama.
From a 2026 perspective, the Tour de Inferno invite event stands out as a textbook retention campaign. It combined social sharing, time-limited rewards, and a lottery with physical prizes that made the stakes feel tangible. PlayStation 5 consoles, scale figures, acrylic stands, and in-game currency all shared the same stage. The event also gave returning players a soft landing: they were not just handed a code and forgotten. They could share their own invitation code and pull others back in, creating a chain of reunions across New Eridu.
Of course, the event is over now. No one can claim those Polychromes or lucky draws in 2026 unless HoYVerse revives the campaign in some form. Still, the structure offers lessons for future versions. Limited-time invite events work because they turn a solo grind into a social occasion. They give lapsed players a reason to log in, and they reward active players for being good neighbors. If a similar event returns in a future Zenless Zone Zero update, the smart move is to read the fine print, check eligibility early, and avoid waiting until the final hours. The event page may be calm, but the deadline is not.
Ultimately, Version 1.2’s invite event was not just about Polychromes. It was about rebuilding a community, one invitation code at a time. And in a city as chaotic as New Eridu, that is no small potatoes.
