Last updated: [03/08/2026]
Zenless Zone Zero’s second anniversary just dropped, and Version 3.1 “The Long Goodbye” hands every player something rare in a HoYoverse game: a completely free limited S-Rank Agent of your choice, plus that character’s signature W-Engine. The catch? You can only pick one from Jane, Soldier 0 – Anby, Hugo, Trigger, or Lucia — and it’s irreversible. Choose wrong and you’re watching an idle character sit in your roster for a year. So let’s get it right.
Quick answer: For most players, Lucia or Jane is the best pick. Lucia is the strongest long-term choice — she’s the premier support for the Rupture archetype and stays relevant across future patches. Jane is the best universal pick and pairs perfectly with Remielle, this patch’s new banner Agent, to form a top-tier Anomaly duo. Pick Lucia for future-proof value, Jane if you’re pulling Remielle, and read on if you already own one of them — because the selector doubles as a Mindscape 2 unlock.
Want your free S-Rank battle-ready with the right discs and level instead of sitting benched while you farm? Our Zenless Zone Zero boosting service handles leveling, Hollow Zero, and material farming so your anniversary Agent hits the field maxed — skip the grind and play the fun part.

What You Actually Get From the Anniversary
Before the pick itself, here’s the full haul so you know what’s landing in your account this patch. The 3.1 anniversary is HoYoverse’s biggest ZZZ reward drop to date:
- One free limited S-Rank Agent — your choice of Jane, Soldier 0 – Anby, Hugo, Trigger, or Lucia
- That Agent’s signature W-Engine — the matching five-star weapon, which normally costs a separate banner pull to chase
- 1,600 Polychrome from login rewards
- 30 pulls’ worth of Encrypted Master Tapes and Boopons across the version’s events
- A free anniversary avatar and title
- Active redemption codes for bonus Polychrome and upgrade materials — see the full list in the Active ZZZ 3.1 Codes section below. The headline anniversary livestream code has already expired, but several Polychrome codes are still live.
The claim window runs the entire patch, so there’s no need to rush the Agent decision on day one. Take the time to pick right — but do redeem the codes soon, since those expire on a much shorter timer than the selector.
The signature W-Engine is what makes this reward genuinely huge. A free limited S-Rank is great; a free limited S-Rank with their best-in-slot weapon is the kind of value that normally takes two separate banners to assemble.
Active ZZZ 3.1 Codes (Verified [INSERT TODAY’S DATE])
These codes are live as of the date above. ZZZ codes rotate and expire fast — usually within days — so redeem them now. If one shows “invalid,” it has likely hit its redemption limit.
| Code | Rewards | Status |
|---|---|---|
| ZZZ31REMIELLE | 60 Polychrome, 6,666 Denny | Active — Version 3.1 |
| ZZZ2YEAR | 50 Polychrome | Active — anniversary |
| ZZZMEIJI | 3 Senior Investigator Logs, 3 W-Engine Energy Modules, 30,000 Denny | Active |
| ZENLESSGIFT | 50 Polychrome, 2 Official Investigator Logs, 3 W-Engine Power Supplies, 1 Bangboo Algorithm Module | Active — permanent |
Note: The Version 3.1 Special Program livestream code (ZZZY2ANNIV) expired July 19, and ZZZSTEAM expired July 29 — don’t waste time on those. New livestream codes typically drop 1–2 weeks before the version ends (~Aug 19), are usually worth around 300 Polychrome, and stay live for only about 24 hours.
How to redeem: Your account must reach Inter-Knot Level 5 first. Then either open Menu → More → Redemption Code in-game, or use the official page at zenless.hoyoverse.com/redemption while logged in. Rewards arrive in your in-game Mailbox — claim them within 30 days before they expire..
Which Agent Should You Pick? Decision Table
Your right pick depends on two things: what your roster already has, and who you’re pulling this patch. Here’s the fast answer:
| Your Situation | Pick |
|---|---|
| You want the best long-term value | Lucia |
| You’re pulling Remielle this patch | Jane |
| You already own a Rupture DPS (Yixuan, etc.) | Lucia — completes the team |
| New player with no main DPS | Hugo — transitional carry |
| You already own Jane / Hugo / Soldier 0 Anby at M0 | That same Agent — unlocks their Mindscape 2 power spike |
| You need an Electric Attacker | Soldier 0 – Anby |
Notice the pattern: there’s no single “correct” answer for everyone, but Lucia and Jane cover the most accounts. If you’re overwhelmed and just want the safe default, Lucia is the pick that ages best.
Every Agent, Ranked for the Selector
Lucia — Best Overall Pick
Lucia is the strongest choice in the pool for long-term value. She’s the premier support for Rupture teams — one of ZZZ’s newest and most future-proofed archetypes — supercharging Rupture damage and shredding enemy Resistance. Because she enables an entire archetype rather than just dealing damage herself, she stays relevant across patch cycles as HoYoverse releases more Rupture DPS built around her. Her signature W-Engine, Dreamlit Hearth, is usable only by her and pushes her buff uptime to near-permanent. If you don’t have a specific reason to pick someone else, pick Lucia.
Jane — Best Universal Pick
Jane Doe is the most balanced option and the timeliest one this patch. She’s a top-tier Anomaly DPS, and she pairs directly with Remielle — the new Lumiflux Agent on 3.1’s banner — to form one of the version’s strongest team compositions. Her signature Sharpened Stinger leans into her dodge-heavy playstyle for a huge Physical damage buff with easy uptime. If you’re pulling Remielle, Jane is the obvious pick; the two together are the meta Anomaly duo. Even without Remielle, Jane is a reliable carry who fits a wide range of teams.
Hugo — Best for New Players
Hugo delivers respectable Ice burst damage and works well as a transitional carry for newer accounts without a main DPS. His signature Myriad Eclipse is a strong CRIT stat-stick that suits his kit. The caveat: his rotation speed can feel sluggish, and his spot in the Ice meta now faces pressure from the hyper-carries released in the later half of 3.1. He’s a solid “get me a functional DPS now” pick, but veterans with an established roster get more from Lucia or Jane.
Soldier 0 – Anby — Situational
Soldier 0 – Anby is a powerful Electric Attack Agent with excellent personal damage, carrying the signature Severed Innocence W-Engine. But she’s primarily a straightforward DPS rather than an archetype-enabler, so she offers less account value than Lucia or Jane. That said, Electric Attackers are rare in ZZZ, so if that’s a hole in your roster, she’s a perfectly reasonable pick.
Trigger — Lowest Priority
Trigger is an easy-to-play Stunner with team-wide Defense shred, and her signature Spectral Gaze provides exactly the DEF-shred value that defines her ceiling — which, conveniently, the selector hands you. Still, if you’re already planning to pull the premium supports now available in 3.1, Trigger becomes redundant fast. She’s the hardest pick to justify for most accounts.
The Mindscape 2 Angle Most Players Miss
Here’s the pro move if you already own one of the selector Agents at Mindscape 0. Instead of grabbing a new idle character, use the selector to pick the same Agent you already have — this pushes them to Mindscape 2, a significant power spike for Hugo, Soldier 0 – Anby, and Jane in particular.
For an Agent you already play and invest in, an M2 upgrade almost always beats adding a brand-new character who’ll sit unused. A maxed, higher-Mindscape Agent in your active rotation is worth more than a fresh S-Rank you don’t have a team for. Check your roster before you pick — if one of these five is already carrying you, doubling down is often the smartest value.
How to Claim Your Free S-Rank Agent
The selector lives in the Version 3.1 anniversary event menu. Here’s the quick path:
- Log in during Version 3.1 — the claim window runs the entire patch (until ~Aug 19), so you don’t have to decide on day one.
- Open the anniversary event from the in-game Events menu (look for the “The Long Goodbye” / 2nd Anniversary banner).
- Select your Agent from the five options — Jane, Soldier 0 – Anby, Hugo, Trigger, or Lucia. The choice is permanent, so confirm your pick against the decision table above.
- Claim the signature W-Engine, which is granted automatically alongside your chosen Agent.
- Check your Mailbox for the Agent, weapon, and anniversary Polychrome — and claim within 30 days.
Don’t Let FOMO Waste Your Pick
The single biggest mistake players make with a free selector is claiming immediately out of excitement. Don’t. The claim window runs the whole patch, so map out your pull plans first. If you’re planning to summon Remielle, that changes your answer. If you’re building toward a Rupture team, that changes it too. Your roster gaps matter more than any community tier list — including this one.
The only thing you should rush is the redemption codes, which expire far sooner than the selector. Everything else can wait until you’ve thought it through.
Claim Your Free Agent — Then Make It Count
A free S-Rank and signature W-Engine is a massive head start, but a character sitting at level one with no discs isn’t winning you anything — the real power comes from actually building them. If you’d rather skip the leveling and material grind, our Zenless Zone Zero boosting service gets your anniversary Agent to Level 60 with EXP materials farmed and promotion rewards included, so they’re field-ready the moment you claim.

Conclusion
The 3.1 anniversary selector is the most generous reward ZZZ has ever handed out, and the right pick comes down to your account. Lucia is the best all-round choice thanks to her future-proof Rupture support role. Jane is the universal pick and the obvious call if you’re pulling Remielle. Hugo bridges the gap for new players, Soldier 0 – Anby fills an Electric slot, and if you already own one of these Agents, the selector doubles as a Mindscape 2 power spike.
Whatever you choose, don’t rush it — the window’s open all patch. Grab the codes now, plan your pulls, then claim the Agent that actually fits your team. Happy anniversary, Proxy.
Frequently Asked Questions
Which free S-Rank should I pick in ZZZ 3.1?
For most players, Lucia or Jane is the best pick. Lucia offers the strongest long-term value as the premier Rupture support, staying relevant across future patches. Jane is the best universal choice and pairs with Remielle, the 3.1 banner Agent, for a top-tier Anomaly team. If you already own one of the five selector Agents, picking the same one unlocks their Mindscape 2 power spike instead.
What are the current ZZZ 3.1 redeem codes?
As of the last update, the active codes are ZZZ31REMIELLE (60 Polychrome, 6,666 Denny), ZZZ2YEAR (50 Polychrome), ZZZMEIJI (logs, W-Engine modules, 30,000 Denny), and ZENLESSGIFT (50 Polychrome plus materials). The anniversary livestream code ZZZY2ANNIV expired on July 19. Codes rotate quickly, so redeem them via the in-game menu or zenless.hoyoverse.com/redemption as soon as possible.
Is the ZZZ anniversary selector agent permanent?
Yes. The free S-Rank Agent you select from the Version 3.1 anniversary event is permanent and comes with that Agent’s signature W-Engine. The choice is irreversible, so it’s worth planning around your roster and pull plans before claiming. The claim window stays open for the entire patch, so there’s no need to rush the decision.
Should I pick Lucia or Jane in ZZZ 3.1?
Pick Lucia for the best long-term value — she enables the Rupture archetype and stays useful as HoYoverse releases more Rupture DPS. Pick Jane if you’re pulling Remielle this patch, since the two form one of Version 3.1’s strongest Anomaly team compositions. If you own neither and want a safe future-proof default, Lucia is the stronger pick.
Can I pick an agent I already own in the ZZZ selector?
Yes, and it’s often the smartest move. If you already own one of the five selector Agents at Mindscape 0, choosing that same Agent pushes them to Mindscape 2 — a significant power spike, especially for Hugo, Soldier 0 – Anby, and Jane. An M2 upgrade on an Agent you already play usually beats adding a new idle character.
What W-Engines come with the ZZZ 3.1 selector?
Each Agent comes with their signature W-Engine: Sharpened Stinger (Jane), Severed Innocence (Soldier 0 – Anby), Spectral Gaze (Trigger), Dreamlit Hearth (Lucia), and Myriad Eclipse (Hugo). The free signature weapon is a major part of the reward’s value, since it normally requires a separate banner to obtain.
How long do I have to claim the free ZZZ agent?
The free S-Rank Agent selector claim window runs for the entire Version 3.1 patch, so you have weeks to decide. However, the anniversary redemption codes for bonus Polychrome and materials expire much sooner, so redeem those immediately even if you wait on the Agent choice.
