Zenless Zone Zero 3.1 Update: The Long Goodbye, Remielle, Sigrid and Anniversary Rewards

Zenless Zone Zero Version 3.1, The Long Goodbye, is the latest major update for the game as of July 29, 2026. The update continues Season 3, brings the first-generation Void Hunter Remielle into the playable roster, introduces Sigrid, launches the second anniversary celebration, and adds a new permanent mode for long-term progression.

The update goes live after maintenance on July 29, 2026, with Version 3.1 scheduled to end on September 9, 2026 at 06:00 UTC+8. Eligible players can receive Polychrome x300 for maintenance compensation and Polychrome x300 for issue-fix compensation, for a total of Polychrome x600 through in-game mail.

Version 3.1 At A Glance

The Long Goodbye: New Main Story

The main story update is Season 3 Chapter 2: The Long Goodbye. It becomes permanently available after the Version 3.1 update and continues the Roscaelifer arc that began in Season 3 Chapter 1, A Sleepwalker's Confession.

The chapter focuses on Remielle, memory, farewell and the weight of history. From the official English preview, Version 3.1 is clearly designed as more than a banner patch: the update uses Remielle's return to deepen the larger Season 3 mystery around Roscaelifer and the legacy of the first-generation Void Hunters.

Players who care about story continuity should finish Season 3 Chapter 1 before starting the new chapter. Players who mainly want access to rewards can still check the in-game event menu and Advance Screening options where available.

Remielle and Sigrid

Version 3.1 adds two new S-Rank Agents.

Remielle is an S-Rank Lumiflux Anomaly Agent. She is the headline Agent of The Long Goodbye and can be obtained through the Paradise Regained Signal Search. Her role points toward Anomaly-based damage and Lumiflux team building, making her especially interesting for players who enjoy status buildup and attribute-focused rotations.

Sigrid is an S-Rank Ice Attack Agent. She can be obtained through the 'Till the Ends of the Sky Signal Search. While Remielle is tied to Anomaly gameplay, Sigrid is positioned more directly as a damage dealer, so she may appeal to accounts that need an Ice carry or prefer a straightforward on-field DPS.

The update also introduces the S-Rank W-Engines Ode of Resurrected Wings and Knight's Extolment, plus the new S-Rank Bangboo Ariel. For most players, the safest pull order is still Agent first, W-Engine second. A signature W-Engine can raise a character's ceiling, but a new Agent usually changes an account more than a weapon upgrade.

Limited Channels in Version 3.1

Version 3.1's limited channels are important because the update contains both new characters and anniversary freebies. Before spending Polychrome, players should first check what the anniversary selector gives their account.

Remielle is the natural pull for players who want the version's main story character, a new Anomaly core, or a Lumiflux-focused team. Sigrid is the better target for players who need a premium Ice Attack Agent. Players with limited pulls should avoid chasing both W-Engines unless they already have enough resources to guarantee their priority Agent.

The exact channel countdown can vary by server display, so use the in-game Signal Search page as the final timer reference.

Second Anniversary Rewards

The second anniversary campaign is the biggest reason every Proxy should log in during Version 3.1. The official English rewards overview confirms that players can claim a strong package of free rewards during the version, including:

· A limited S-Rank Agent of choice

· A corresponding limited S-Rank W-Engine of choice

· Polychrome x1,600

· Encrypted Master Tape x20

· Boopon x10

· An anniversary avatar and title

· Lucy's free outfit, Princess on Holiday, from the Summer Waves Roll In event

· Pyrois Mindscape and W-Engine overclock materials through gameplay

The limited S-Rank Agent selector includes Jane, Soldier 0 - Anby, Trigger, Lucia and Hugo, with corresponding W-Engines available through the related choice reward. Version 3.1 also adds Tsukishiro Yanagi, Caesar and Zhu Yuan, plus their exclusive W-Engines, to Custom Search.

For new players, this is one of the best entry points the game has offered so far. For returning players, the selector can fix a roster gap before any Polychrome is spent.

Marcel Anniversary Gift

The Marcel Anniversary Gift event runs from after the Version 3.1 update until the end of Version 3.1. Players need to reach Inter-Knot Lv. 5 and unlock the Event feature in the Main Story Prologue to participate.

This is the event to clear first because it contains the most account-defining anniversary rewards. If you are returning after a break, prioritize opening the event page, checking its requirements, and claiming every reward before the version ends.

New Permanent Mode: Enigma of the Labyrinth

Version 3.1 adds Enigma of the Labyrinth: Operation Bagel, a permanent mode that opens on August 5, 2026 at 10:00 server time. It requires Inter-Knot Lv. 40.

In this mode, Proxies enter the Hollow, collect supplies, complete commissions, craft equipment, repair research-station infrastructure and evacuate. The reward pool includes Polychrome, shop items, Agent Focus: Pyrois, Proxy accessories and other progression materials.

Because Enigma of the Labyrinth is permanent, players do not need to rush it like a limited-time event. Still, unlocking it early is useful because it adds another long-term reward path to the account.

Events, Outfits and System Updates

Version 3.1 includes a full event slate. The most important login events are Gift From the Clouds, which gives Encrypted Master Tape x10, and The Great En-Nah Giveaway!, which gives another Encrypted Master Tape x10 plus Boopon x10. Event gameplay includes Summer Waves Roll In, Snap! Focus Showdown!, Crispy Meal Deployment Plan, Dangerous Fugitive's Leisurely Vacation, and Ding-Dong! Delivery Training in Progress.

Outfits are also a major part of the update. Remielle receives Seashade Pas Seul and Moonlight Whispers, while Sigrid receives Majestic Wavechaser later in the version. Lucy's Princess on Holiday outfit can be obtained for free through Summer Waves Roll In.

System additions include a new Beginner Guide, batch lock and unlock options for A-Rank W-Engines, new Drive Disc acquisition content, Dynamic Wallpapers for Remielle and Sigrid, new achievements, new enemies, Crowd Density graphics settings and DX12 support for select AMD graphics cards.

Should You Pull in ZZZ 3.1?

If you want Remielle as a character or need an Anomaly centerpiece, Version 3.1 is an easy banner to justify. If your account lacks an Ice carry, Sigrid may be the more practical target. If you are low on Polychrome, claim the anniversary selector first, then decide whether your roster still needs either new Agent.

The key point is that Version 3.1 gives players more free value than a normal patch. That means saving is more reasonable than usual. A free limited S-Rank can cover a missing role, and the W-Engine selector can strengthen a chosen team without forcing you into the weapon banner.

Final Take

Zenless Zone Zero 3.1 is a strong anniversary update because it combines story momentum, free account value and two high-profile new Agents. The Long Goodbye gives Season 3 a heavier emotional focus, Remielle anchors the version's identity, Sigrid adds another premium combat option, and the anniversary rewards make the patch worth logging into even for players who are not ready to pull.

For a low-time player, the priority list is simple: claim compensation mail, open Marcel Anniversary Gift, collect login rewards, unlock Enigma of the Labyrinth when eligible, and then decide whether Remielle or Sigrid fits your account better.
