Zenless Zone Zero turns two with Version 3.1 “The Long Goodbye,” and HoYoverse is marking the occasion with the game’s largest reward drop to date. The update lands on July 29, 2026, and the standout gift is a free limited S-Rank Agent of your choice paired with that character’s signature W-Engine. On top of that sit 1,600 Polychrome, 30 pulls’ worth of tapes and Boopons, a free outfit, and a redemption code you can grab right now.
Quick answer: Log in during Version 3.1 to pick one free limited S-Rank Agent from Jane, Soldier 0 – Anby, Trigger, Lucia, or Hugo, plus a matching W-Engine. Redeem code ZZZ2YEAR in-game, then claim the login and check-in events for 1,600 Polychrome, 20 Encrypted Master Tapes, and 10 Boopons.
Free S-Rank Agent and W-Engine selector
The centerpiece of the anniversary is a select-one gift. During the event, you choose a single limited S-Rank Agent from a pool of five and receive that character’s signature W-Engine for free alongside it. The reward should appear as an option on the event screen once you log in after the update goes live.
| Agent | Attribute and role | Signature W-Engine |
|---|---|---|
| Jane Doe | Physical, Anomaly | Sharpened Stinger |
| Soldier 0 – Anby | Electric, Attack | Severed Innocence |
| Trigger | Electric, Stun | Spectral Gaze |
| Lucia | Ether, Support | Dreamlit Hearth |
| Hugo | Ice, Attack | Myriad Eclipse |
You only get one Agent and one engine, so pick the character that completes a team you can already field rather than the one with the flashiest kit. A carry with no stun or support around it will struggle in endgame modes, so weigh the pick against the three Agents you already own.
Polychrome, tapes, and the 30 pulls
Beyond the selector, the anniversary hands out a stack of pull currency spread across a login gift and check-in events. Added together, the tapes and Boopons come out to 30 pulls, with the Polychrome sitting on top.
| Reward | Amount | How to get it |
|---|---|---|
| Polychrome | 1,600 | Log in during the event |
| Anniversary avatar and title | 1 each | Log in during the event |
| Encrypted Master Tapes | 20 | Check-in events |
| Boopons | 10 | Check-in event |
The check-in rewards are split across daily login events that run through Version 3.1, so you need to open the game across several days to collect everything. New players get an even bigger head start, with HoYoverse pointing to up to 180 pulls in total once starter and event bonuses are combined.
Redemption code: ZZZ2YEAR
HoYoverse released a live anniversary code, ZZZ2YEAR, which grants Polychrome and upgrade materials. Anniversary codes expire quickly, so redeem it as soon as you can rather than waiting for the patch.
ZZZ2YEAR exactly and confirm.You know it worked when a confirmation appears and the reward mail shows up in your Inbox. If the code is rejected, it has usually already expired or your account region does not match.
Standard pool additions and Custom Search
Version 3.1 also expands the permanent roster. Tsukishiro Yanagi, Caesar, and Zhu Yuan join the standard pool along with their exclusive W-Engines, and you can now pull for them through Signal Search.
A new Custom Search feature lets you designate a non-rate-up S-Rank Agent and W-Engine, plus featured A-Ranks, ahead of pulling. That selection pool includes the standard S-Ranks alongside Yanagi, Caesar, and Zhu Yuan, giving you more control over where saved Master Tapes go.
Free outfit, Pyrois materials, and top-up reset
The anniversary rewards reach beyond currency. Lucy’s “Princess on Holiday” swimsuit outfit is free to claim by completing the Summer Waves Roll In event, which takes place at Fantasy Resort with Lucy, Sigrid, and Remielle. That event also hands out Polychrome, upgrade materials, and the A-Rank Bangboo Overtimeboo.
Pyrois, the Season 3 protagonist avatar, gets a boost too. Through gameplay you can earn two of Pyrois’s Mindscape Cinemas and overclock materials for their W-Engine at no cost.
Finally, the first-purchase double bonus in the Monochrome Market resets when the new version launches. If you have already used the top-up bonus before, it becomes available again, giving you another round of bonus Monochromes.
| Reward | Source |
|---|---|
| Lucy’s Princess on Holiday outfit | Summer Waves Roll In event |
| A-Rank Bangboo Overtimeboo | Summer Waves Roll In event |
| Pyrois Mindscapes ×2 and W-Engine overclock materials | Version 3.1 gameplay |
| Monochrome first-purchase double bonus | Reset at launch |
When to claim and how to prepare
Version 3.1 arrives in two phases. Remielle’s banner headlines the first half starting July 29, with Aria as the returning rerun and the new Bangboo Ariel debuting. Sigrid features in the second half, which begins August 19, alongside a rerun that lets you pick Dialyn, Asaba Harumasa, or Ukinami Yuzuha.
The login and check-in rewards run on timers, so miss days and you miss pulls. Bank your Polychrome and Master Tapes before launch instead of spending down to zero, then log in daily once the patch is live so the anniversary influx actually moves your account rather than expiring in your mailbox.
